This Privacy Policy describes how Celis Collective LLC doing business as Chemistry (“Chemistry”, “we”, “us”, or “our”) collects, uses, and discloses your personal information when you visit our website, book or attend a class or session, make a purchase, or otherwise communicate with us (collectively, the “Services”).
For the purposes of this Privacy Policy, “you” and “your” means you as a user of the Services, whether you are a client, website visitor, or another individual whose information we have collected.
Please read this Privacy Policy carefully. By using or accessing any of the Services, you agree to the collection, use, and disclosure of your information as described here. If you do not agree, please do not use the Services.
Changes to This Privacy Policy
We may update this Privacy Policy from time to time to reflect changes to our practices or for other operational, legal, or regulatory reasons. We will post the revised policy on this page, update the “Last updated” date, and take any other steps required by applicable law.
What Personal Information We Collect
The information we collect depends on how you interact with us.
Information you give us directly
- Contact details, including your name, email address, phone number, and emergency contact information.
- Date of birth, which we use to confirm you are old enough to sign our waiver yourself, and — only if you have opted in to marketing — to send you a birthday message.
- Booking and account information, including your class history, class pack balance, login credentials, and scheduling preferences.
- Payment information. Payments are processed by our third-party payment processor. We do not store your full card number. We receive limited details such as the last four digits, card type, billing name, and confirmation of payment.
- Health and fitness information that you provide on intake forms, liability waivers, or verbally to your instructor. This may include injuries, medical conditions, surgeries, physical limitations, pregnancy or postpartum status, healthcare provider clearance, medications relevant to exercise, and your fitness goals.
- A record that a form was submitted from your connection. The contact form, the coaching application and the email signup each limit how many times they can be used from one internet connection in a day, which is how we keep automated spam out without making you solve a puzzle. To do that we store a one-way scrambled version of your IP address, which we cannot turn back into the address itself. It is used for nothing else.
- Coaching application information. If you apply for one to one coaching, we collect your name, email address, phone number, age, Instagram handle, country and state, employment status and occupation, how you rate your readiness to change, and your written answers about your goals and what you have found difficult. We use it only to decide whether coaching is a fit and to reply to you. We do not use it for advertising and we do not sell it. If we do not work together, we keep your application for 12 months and then delete it.
- Communications, including messages you send us by email, text, direct message, or through any form on our website. When you use the contact form we collect your name, your email address, the subject you pick if you pick one, and what you write. We store it so that a message cannot be lost if our email provider is having a bad day, we use it only to answer you, and we keep it for 12 months and then delete it.
Information collected automatically
When you visit our website we may automatically collect usage data using cookies, pixels, and similar technologies. This may include device information, browser type, IP address, pages viewed, and how you interact with the site.
Information from third parties
We may receive information from service providers who support our business, including our booking and scheduling platform, our payment processor, our email marketing provider, and website analytics providers.
We are not responsible for the accuracy of information provided to us by third parties, or for the privacy practices of those third parties.
Photographs and video
We may photograph or record classes, sessions, and events for marketing and educational purposes. See our Terms and Conditions for how to opt out.
How We Use Your Personal Information
- Providing our services. To register you as a client, process bookings and payments, track class pack balances and expiry, manage waitlists, and send confirmations, reminders, and schedule changes.
- Health and safety. To adapt exercises to your body, provide appropriate modifications, decide whether a format is suitable for you, and respond in an emergency. Health information is used only for these purposes and is shared with instructors only to the extent needed to keep you safe.
- Communicating with you. To answer questions, provide client support, and maintain our relationship with you.
- Marketing. If you have opted in, to send you promotional emails, offers, workshop and schedule announcements, studio news, and a birthday message. Marketing is optional and separate from our waiver — you can decline it and still book classes — and you can withdraw it at any time.
- Improving our services. To understand how our website and classes are used and to improve them.
- Security and fraud prevention. To detect, investigate, and act on fraudulent, illegal, or malicious activity.
- Legal compliance. To comply with legal obligations, enforce our Terms and Conditions, and protect our rights and the rights of others.
Marketing Emails and Birthday Messages
Marketing email is opt-in. We send it only if you have ticked the marketing box, which sits separately from the liability waiver. Declining it does not affect your ability to book, and accepting the waiver does not sign you up for it.
If you opt in, we may email you about offers, discounts, class packs, workshops, schedule announcements, studio news, and milestones in your own practice, and we may use your date of birth to send you a birthday message. We do not sell your personal information, and we do not share it with third parties for their own marketing.
You can turn marketing off at any time from My account in the booking app, or by using the unsubscribe link in any marketing email.
Turning marketing off does not stop the emails you need in order to use the studio — booking confirmations, waitlist notifications, cancellations, schedule changes, receipts, and fee notices. Those are part of the service and are sent whether or not you have opted in.
Email list
When you enter your email in the offer on The Formula page, we save your address and add you to our email list. We send you your discount code, and after that we may send you occasional emails from CHEMISTRY. We keep a record of when you signed up and the wording you agreed to. Our emails are sent through Resend. Every email includes an unsubscribe link. Unsubscribing does not affect your account, receipts, or program emails if you are a member. To have your address deleted, email us at hello@feelthechemistry.co.
If you unsubscribe, we ask whether you would like to say why. Answering is optional, we store only the words you type and the date, and we never publish it or share it.
Reviews
If you have access to one of our online programs, you can write a review inside the program itself. Reviewing is optional, nothing in the program depends on it, and you can leave it blank for as long as you like.
When you submit one we collect your written answers, your rating out of five, and the first name you enter on the form. You can add your age if you want to, and reviews are for members aged 18 or over. You can add up to three photos. We also record which week you were on and how many workouts you had finished when you wrote it, so that we can read the review in context. If you tell us how many rounds of the program you had completed before joining the platform, and which month you first started, we store both as you gave them to us.
Your first name is prefilled from your profile and you can change it on the form. Your age is not prefilled. We keep the values you entered on the review itself, so editing your profile later does not quietly rewrite something already published.
The four permissions
You answer four separate questions, and each one controls a different thing. You can say yes to one and no to another. All four start switched off, so a review you submit as it is stays private.
- Publish the words. We show your review only if you say yes. We read every review either way.
- Show the first name and age. We show your first name, and your age if you gave one, only if you say yes. Otherwise the review appears without either.
- Show the photos. We show your photos publicly only if you say yes, whatever you answered to the other three.
- Use in ads and social posts. We use your review or photos in our advertising or on our social media accounts only if you say yes. If you say yes and later change your mind, we stop using them in new ads and posts, and remove them from our own accounts on request. Changing only this answer does not affect whether your review appears on our website.
A review is only shown publicly once we have also approved it. Approval and permission are separate: your permission alone does not publish anything, and our approval alone does not either.
Photos
A photo goes to private storage first, exactly as your phone sent it. We then process it: we bake in the rotation, resize it so its longest edge is no more than 1600 pixels, convert it to JPEG, and discard all of the file’s metadata in doing so. That metadata is where a camera records GPS coordinates, the device, and the time the photo was taken, so none of that survives processing.
The original is deleted as soon as it has been processed. If processing fails, the original is deleted automatically within the hour. It is never public and it is never linked to your review.
The processed copy stays private. A public copy is made only when your review has been approved and you have said yes to showing photos, and only that copy is ever reachable from the website.
Changing your mind
Your four permissions are read every single time the site asks for reviews, not recorded once at publication, so a change takes effect from then on rather than only for future reviews.
You can change all four yourself in the program, on the same form you used to write the review. Saving any change sends the review back to us to approve again, which means it stops being shown in the meantime. If you would rather we did it, or you want the review deleted outright with its photos, email us at hello@feelthechemistry.co.
Feedback
Feedback is separate from reviews and is never published. If you send us feedback from inside the program, we collect your written answers, the topic you chose, whether you asked us not to use your name, and which week you were on and how many workouts you had finished at the time. It is linked to your account. We read it to improve the program. It is not shown on the website and it does not appear in reviews.
Review Invitations
We ask Trustpilot to invite you to review us. For an online program that happens when you buy it. For studio classes it happens after your third attended class, once only, however many classes you attend after that.
What we share with Trustpilot is the email address the invitation goes to, and for a class invitation the name you gave us. We share it for that purpose only, and we do not send an order or booking reference.
The invitation comes from Trustpilot, not from us, and Trustpilot decides when to send it. You do not have to respond to it, and whether you write a review makes no difference to your purchase, your classes, your access, or anything else about your account. Any review you publish is held by Trustpilot under its own privacy policy, which you can read at legal.trustpilot.com/end-user-privacy-terms, and remains between you and Trustpilot.
If you would rather not be invited, email us at hello@feelthechemistry.co and we will exclude you.
Health Information
We treat health information with particular care.
- We collect only what we need to keep you safe during exercise.
- We do not sell health information, and we do not share it for cross-context behavioral advertising. The Meta pixel described below runs only on our program page, which collects no health information.
- We do not use health information for marketing purposes.
- Access is limited to your instructor and to those who need it to deliver or administer your sessions.
- We are not a healthcare provider and we are not a covered entity under HIPAA. The information you share with us is not protected health information under that law, but we handle it as sensitive personal information under California law.
If you are in Washington State, the My Health My Data Act gives you additional rights over health information, and that law requires us to set them out on a page of their own. See our Consumer Health Data Privacy Policy.
You may decline to share health information, but doing so may limit our ability to provide safe instruction, and we may decline to accept your booking as a result.
The health information described here is what you give us for your safety, such as intake forms. It does not include photos you choose to add to a review, which we publish or use only with your permission and after we approve the review, as described under Reviews.
A coaching application is health information too. What you write about your body, your health and what you have found difficult is treated the same way as anything on an intake form, and it is read only by Ana.
Information from the member app is health information too, and we treat it the same way. That means what you record in your meal log, the nutrition targets you save, and anything we receive from a device you have connected. We do not use any of it for advertising, we do not sell it, and we do not share it with other members. See CHEMISTRY On Demand below for how each part works.
CHEMISTRY On Demand
CHEMISTRY On Demand is our members’ app, at ondemand.feelthechemistry.co and as our iPhone app. Some of what it does is described here rather than above, because it collects different information in different ways.
The meal log
The meal log is part of The Anti-Inflammatory Edit, a paid program. You can record a meal in four ways: take up to three photos of it, type a description, photograph a barcode, or photograph a nutrition label.
What happens to a photo. Before anything leaves your phone or computer, your browser resizes the photo and saves it again in a smaller form. That step removes the hidden data a camera attaches to a picture, including where it was taken. We never receive the original file and we never receive your location from a photo.
The smaller photo, and anything you typed, is sent to Anthropic’s Claude AI so it can estimate the foods in the meal, the portions, the calories and macronutrients, and a short read on how anti-inflammatory the meal looks. We do not keep the full-size photo. We keep only a thumbnail, about 320 pixels across, in private storage, so you can recognise the meal when you look back at your log.
Barcodes. When you photograph a barcode we send the barcode number, and nothing else, to Open Food Facts, a public food database, to look up the product. No photo and no personal information go with it.
You decide what gets saved. Every estimate is shown to you first. You can change any part of it before you save, and nothing is saved until you do. What we store is the meal name, the foods and amounts, calories and macronutrients, the pattern notes, the time of the meal, your water intake, and your nutrition targets if you have set any.
You can turn the numbers off. If you would rather not see calorie and macronutrient figures at all, you can switch them off in the app.
You can change or delete anything. You can edit any meal, and you can delete one. Deleting a meal deletes its photo too.
Who can see it. Your meal log is yours. Other members cannot see it, and we have not built any way for our staff to open it in the app.
Meal ideas. If you ask for meal ideas, you can photograph your groceries or your fridge, or type what you have. That photo or text is sent to Anthropic’s Claude AI, together with what is left of your day’s targets, so it can suggest meals. We do not keep the photo. The ideas are not saved unless you log one as a meal.
What the AI estimate is, and what it is not
These estimates are educational and approximate, and they can be wrong. They are not medical advice, not dietetic advice, and not a substitute for care from a qualified professional. They are not suitable for medical nutrition therapy, for treating an eating disorder, for pregnancy, or for managing a medical condition. If you are dealing with any of those, please work with a professional who knows you.
The calorie calculator
The calculator asks for your age, sex, height, weight, activity level and goal. We do not store any of those. They exist only in your browser while the page is open, and they are gone when you leave it.
If you tap “Use these in my meal log”, we save the results only: your goal, your macronutrient split, your maintenance calories, and your calorie and macronutrient targets. We never save your age, your height or your weight.
The AI uses those saved targets to tailor what it suggests. It does not tell you that you ate too much.
Cycle tracking
Cycle tracking is optional and off until you turn it on. When you turn it on we record that you agreed and when.
What we store. Only what you log: the days of your period and how heavy it was, LH (ovulation) test results, the symptoms you tick, and your energy from one to five. If you have connected Oura or Apple Health, we also use your nightly temperature change from your own usual, described under Connected devices below. From these the app works out your cycle day, your phase, and its own averages for your cycle and period length.
Estimates only, not birth control. The app shows an estimate of your next period and of your fertile window, and marks days as fertile, maybe fertile or low fertility, always labelled as estimates. They can be wrong, especially when cycles are irregular. Do not use CHEMISTRY to prevent pregnancy or to plan one. It is not a medical device, not contraception, and not medical advice.
Who can see it. Only you. Other members cannot see it, and we have not built any way for our staff, Ana included, to view anyone’s cycle data. It is not sent to Anthropic or any other AI, it is never used for advertising or marketing, it is not shared with Meta or any advertiser, and it is not sold.
Your home screen. If you add the cycle widget to your iPhone, your cycle day and phase are shown on your home screen and lock screen, where anyone holding your phone can see them. The widget is optional.
Deleting it. “Delete my cycle data” in the app deletes every cycle log and turns tracking off, straight away. Deleting your account deletes it too.
Connected devices
Connecting a device is optional. You choose whether to connect one, and you can disconnect it at any time from your Profile.
Oura. You connect through Oura’s own sign-in, so we never see your Oura password. We ask for read-only access to your daily data, which covers steps, activity, active calories, sleep including resting heart rate during sleep, and your nightly temperature change from your usual (which we use only for cycle tracking, if you have turned it on), and to your workout data. We keep Oura’s access tokens securely on our servers. You cannot see them, and we never share them. We sync about once an hour.
Disconnecting Oura deletes the tokens and all of the Oura data we have stored for you. You can also withdraw our access from inside the Oura app. Some Oura ring models need an active Oura Membership for this data to be available.
Apple Health. In our iPhone app, and only if you give permission in Apple’s own Health screen, the app reads your steps, exercise minutes, active energy, walking and running distance, sleep, resting heart rate and, from an Apple Watch, your sleeping wrist temperature, and sends daily totals to us. Wrist temperature is sent as the change from your own usual and is used only for cycle tracking. The app reads only; it never writes anything to Apple Health. We do not use Apple Health data for advertising or marketing, we do not sell it, we do not use it for anything you have not agreed to, and we share it with no one except the service providers needed to run the app. You can turn access off at any time in your iPhone’s Settings, under Health, and the app stops reading straight away.
Who sees device data. You do. It appears on your Today and Progress pages and in your meal log. It is not shown to other members, it is not used for advertising, and it is not sold.
Notifications
If you allow notifications in our iPhone app, your phone gives us a notification address for it, which we store with your account so we can send you workout reminders, replies to your comments, group chat messages and news from Ana. You choose which of these you get in the app, and you can turn them all off in your iPhone’s Settings. Notifications are delivered by Apple’s push notification service. We do not put health information in them.
Workout history
When you log a workout, we keep each session: the date, how long it was, and the reps and weights you logged, so you can see your history and how you are progressing. Only you can see it.
Deleting your account
You can delete your account yourself in the app, under You. Before it goes you can tell us why, if you want to; that answer is kept with no name, email or anything else that points back to you.
Deleting your account deletes your login, your profile, your reviews, your meal log and its photos, your workout history, your cycle data, your connected-device data and your notification settings. Two things stay, and the app tells you so before you delete: the record of what you bought, with the name and email on it, which we keep for our accounts and tax records; and the comments you posted, which stay in their conversations under your username. That username is then reserved, so nobody else can take it. If you would rather your comments were removed too, email us at hello@feelthechemistry.co.
Service providers for the app
These companies process information on our behalf so the app can work. Their own privacy terms apply to what they hold.
- Supabase, for our database, file storage and member sign-in.
- Vercel, which hosts the app. Its servers are in the United States.
- Anthropic, which provides the Claude AI that estimates meals. Anthropic acts as a processor for us, which means it handles what we send only to do the job we asked for. It deletes what we send within 30 days, and it does not use it to train its models. There are exceptions it publishes: if its safety systems flag something it may keep it for up to two years, and safety classification scores for up to seven years. We do not send your name or your email address with a meal, only the resized photo or the text you wrote.
- Open Food Facts, for barcode lookups. Only the barcode number is sent.
- Oura, and only if you have chosen to connect it.
- Apple, for Apple Health (only if you allow it) and for delivering notifications (only if you allow them).
How We Disclose Your Personal Information
We may disclose your personal information to:
- Service providers who perform functions on our behalf, including our booking platform, Stripe as our payment processor, email provider, review platform, and analytics providers, and who are permitted to use it only to provide those services to us. For the member app these are Supabase, Vercel, Anthropic, Open Food Facts, and Oura if you have connected it, each described under CHEMISTRY On Demand.
- Professional advisors such as lawyers and accountants, where necessary.
- Legal and safety recipients, where required by law, in response to lawful requests, to enforce our Terms, or to protect the rights, property, or safety of any person, including emergency responders in the event of a medical emergency during a class or session.
- A successor entity, in connection with a merger, sale, or other business transfer.
We do not sell your personal information for money.
We do use the Meta pixel on our program page at feelthechemistry.co/formula to measure our advertising. Under California law, that counts as sharing personal information for cross-context behavioral advertising, so we describe it that way here rather than claiming otherwise. It applies to that page only. You can stop it at any time using the Do Not Sell or Share My Personal Information link at the bottom of that page, and we honor Global Privacy Control. See The Meta pixel on The Formula page below.
Cookies
Like most websites, we use cookies and similar technologies to operate our website, remember your preferences, and understand how the site is used.
Most browsers accept cookies by default. You can set your browser to remove or reject cookies through your browser controls. Blocking cookies may cause parts of the website to work incorrectly or become unavailable.
The fat-loss calorie calculator
The calculator runs on your device. We store only your email, your consent choice and your result.
Your age, height, weight and activity level are used by your own browser to work out the number and are never sent to us or to anyone else. They are not stored, and they are not shared with Microsoft Clarity, the Meta pixel, or any other analytics tool. If the calculator tells us anything at all, it tells us that someone completed it — never what she entered.
Website analytics on The Formula page
On our program page at feelthechemistry.co/formula, we use Microsoft Clarity to understand how visitors use the page. Clarity records how the page is used, including clicks, scrolling, mouse movement, and details about your device and browser. Microsoft acts as an independent data controller for the information it collects. You can read how Microsoft handles it in the Microsoft Privacy Statement.
Clarity hides what you type into form fields, so your entries, including your email address, never appear in a recording.
Clarity runs only on that page. It is not on any other page of this website, and it is not in the member app.
The checkout page
Checkout at feelthechemistry.co/formula/checkout is handled by Stripe, our payment processor. Your card details are entered into fields hosted by Stripe and go directly to Stripe. We never receive or store your full card number; what we see is the result of the payment, the last four digits, and the card brand.
Stripe sets its own cookies and collects device and browsing information on that page for fraud prevention, which is how it tells a real buyer from a stolen card. Stripe acts as an independent controller for that. You can read how it handles the information in the Stripe Privacy Policy.
Neither Microsoft Clarity nor the Meta pixel runs on the checkout page. Nothing records the page where you enter your card, and no advertising tool is loaded there.
The Meta pixel on The Formula page
On the same program page we use the Meta pixel to measure our advertising: it tells us which ads lead to a purchase, so we are not paying for ads that do not work. It runs only on that page. It is not on any other page of this website, and it is not in the member app.
The pixel runs by default when you open that page. We do not ask you to accept it first. It sets the _fbp and _fbc cookies and reports page views and purchases to Meta, which acts as an independent controller for what it receives. You can read how Meta handles it in the Meta Privacy Policy.
How to opt out. The notice on that page has an Opt out button, and the same control is behind the Cookie settings and Do Not Sell or Share My Personal Information links at the bottom of it. Opting out stops the pixel, stops any further events, and expires the cookies it has already set. Your choice is stored in your browser for 365 days. It is per browser and per device, so opting out on your phone does not opt out your laptop, and clearing your browser data clears it.
Global Privacy Control. If your browser or an extension sends a Global Privacy Control signal, we treat it as an opt-out and the pixel does not run at all. You do not need to do anything else.
Clarity runs without cookies unless you accept. Without cookies, it treats each page view separately and cannot recognize you on a later visit. If you accept, Clarity uses cookies, some set by Microsoft, to recognize a returning visitor. The notice on that page has an OK button and an Opt out button, and opting out is as easy as accepting. OK lets Clarity use cookies. Opt out keeps Clarity cookieless and also stops the Meta pixel described above. You can change your choice at any time with the Cookie settings link at the bottom of that page.
Data Retention
We retain your personal information for as long as needed to provide the Services and for the purposes described in this policy.
Client records, including intake forms and signed waivers, are retained for as long as you remain a client and for a period afterward as needed to comply with legal obligations, resolve disputes, and defend against claims. Retention periods for waivers and injury-related records are generally set by the applicable statute of limitations.
In the member app, what you record stays until you remove it. Deleting a meal deletes its thumbnail at the same time. Disconnecting a device deletes that device’s access tokens and the data we stored from it. Deleting your account deletes your app data straight away, as described under Deleting your account above, apart from your purchase records and your comments, and anything else we are required to keep by law.
Security
We take reasonable measures to protect your personal information. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.
In the member app, access rules are enforced by the database itself rather than only by the app, so each member can read only her own records. Where we limit how often something can be requested, we identify the request by a hashed value rather than by storing the identifier itself.
If you have an account with us, you are responsible for keeping your login credentials confidential. Please contact us immediately if you believe your account has been compromised.
Your Rights
Depending on where you live, you may have the following rights:
- Access. Request confirmation of whether we process your personal information and request a copy of it.
- Correction. Request that we correct inaccurate personal information.
- Deletion. Request that we delete your personal information, subject to legal exceptions. We may need to retain waivers and injury-related records to defend against potential claims. In the member app you do not need to ask us: you can delete any meal yourself, and disconnecting a device deletes what we stored from it.
- Portability. Request a copy of your personal information in a portable format.
- Limit use of sensitive personal information. Request that we limit the use of sensitive personal information, including health information, to what is necessary to provide the Services.
- Opt out. Opt out of marketing communications at any time by using the unsubscribe link in any email or by contacting us.
- Non-discrimination. We will not discriminate against you for exercising any of these rights.
California residents
If you are a California resident, you have the rights described above under the California Consumer Privacy Act as amended by the California Privacy Rights Act. You may also designate an authorized agent to make a request on your behalf.
Opt out of sharing for cross-context behavioral advertising. The Meta pixel on our program page is the only such sharing we do. Use the Do Not Sell or Share My Personal Information link at the bottom of that page, or send a Global Privacy Control signal, which we honor. You do not need an account and we will not ask you to verify your identity to opt out.
To exercise any of these rights, contact us at hello@feelthechemistry.co. We may need to verify your identity before responding, and we will respond within the timeframe required by law.
Children
Our Services are not directed to children under 18, and we do not knowingly collect personal information from anyone under 18 without parental or guardian consent. If you believe we have collected information from a child without consent, please contact us and we will delete it.
The member app is for adults. You must be 18 or over to use the meal log and the calorie calculator, as set out in our Terms and Conditions.
Third Party Websites and Links
Our website may link to third-party websites, including our booking platform and social media profiles. We are not responsible for the privacy practices of those third parties. We encourage you to review their privacy policies before providing them with any information.
