Privacy Policy

Last updated November 6, 2026

The short version. In the app, we collect what we need to build and adjust your training and nutrition plan, and nothing else. We don't sell your data, we don't show ads, and we never use Apple Health data for advertising. Your progress photos never leave your phone. You can delete your account and everything in it from inside the app at any time.

This policy covers the Locked In Health iPhone app, its Apple Watch app, its App Clip and the website at lockedin.health (together, "Locked In"). "We" and "us" means Locked In Health.

What we collect

Workouts: exercises, sets, reps, weights and effort	To track progress and decide next week's targets	Our servers
Food log: foods, portions, calories and macros you log, and weigh-ins	To track your nutrition and adjust targets	Our servers

Meal photos you choose to take or pick	To estimate what's on the plate	Only if you allow AI: sent to our server and to Anthropic to make the estimate, then discarded. We don't store meal photos.
Meals you describe by typing or talking, when you tap "Log with AI"	To work out the foods and portions	Only if you allow AI: sent to our server and to Anthropic, then discarded. The foods you log go in your food log.

What stays on your phone

Your first name. If you tell the coach what to call you, or Sign in with Apple shares your name, your first name is saved only on your iPhone and used to greet you. It isn't sent to us or to our AI provider.
Progress photos. They're saved only on your iPhone, encrypted while it's locked, and never uploaded to us or anyone else. Deleting the app deletes them.
Your voice. In the app, when you answer the coach out loud or tap "Say it" to log food, your speech is turned into text on your iPhone. Recordings aren't saved or sent anywhere. In the App Clip you answer by tapping or typing; it doesn't record your voice.
Apple Health data. With your permission we read sleep, heart rate variability, resting heart rate, steps and body weight from Apple Health. We use them on your phone to show recovery hints and to tune your calorie estimate. Your sleep, heart rate variability, resting heart rate and step readings stay on your phone. Two things leave it: body-weight readings come in as weigh-ins, and your weekly check-in summary can note your average sleep or that recovery looked lower (for example "Sleep averaged 6.2 h"), which is saved with the check-in. With your permission we also save your strength workouts and logged meals to Apple Health.
Camera. The camera feed used to line up progress photos is checked on your phone. It isn't recorded or sent anywhere.

Apple Health

Information from Apple Health is never used for advertising or marketing, never sold, and never shared with data brokers. It's used only to provide Locked In's fitness and health features to you. The only outside service that sees any of it is Anthropic, and only the weekly check-in summary, only to write your own check-in, and only if you allow AI. You can change or revoke access any time in the Health app or in Settings › Privacy & Security › Health.

Who we share it with

We don't sell or rent your personal information, and we don't share it for advertising. We use a small number of service providers to run Locked In, and they may process your data only to provide their service to us:

Supabase stores your account and the data in the table above.
Vercel hosts our website and the server the app talks to.
Anthropic provides Claude, the AI that estimates meal photos, reads meals you type or say, and writes weekly check-in replies. The app asks before anything is sent, and you can turn it off any time in Profile › AI. We send it the meal photo, the words you logged, or a summary of your week (training, food, weigh-ins, your check-in answers, and any sleep or recovery note from Apple Health). We don't send your name or email. Under its commercial terms, Anthropic doesn't train its models on this data.
Open Food Facts receives only the barcode number you scan.
Apple handles Sign in with Apple, push notifications and App Store payments.

We may also disclose information if the law requires it, to protect someone's safety, or as part of a merger or sale of the business, in which case this policy will continue to apply to your data.

How long we keep it

We keep your data while you have an account. When you delete your account, we delete your profile, screening answers, workouts, food log, weigh-ins, check-ins and sign-in record right away. Copies in our providers' routine backups are deleted as those backups expire, normally within 30 days. Launch-list entries stay until you ask us to remove yours.

Your choices and rights

Delete your account: in the app, go to Profile › Delete account. This deletes everything listed above.
Access or correct: most of your data can be seen and edited in the app. For a copy of everything we hold about you, email us.
Launch list: email us and we'll take you off it.
AI: Profile › AI turns the AI features on or off. Without them, barcode scanning, food search and quick add still work, and check-ins come as a standard summary.
Permissions: you can turn off Apple Health, camera, microphone, speech recognition and notifications at any time in iPhone Settings. The rest of the app keeps working.

Depending on where you live (for example California, or the UK and European Economic Area), you may have extra rights to access, correct, delete, or move your data, or to object to how it's used. Email us to use any of them. We won't treat you differently for doing so.

Age

Locked In is for adults 18 and over. We don't knowingly collect data from anyone under 18. If you believe a minor has created an account, email us and we'll delete it.

Security

Data is encrypted in transit and at rest with our storage provider, and each account can only read its own data. No system is perfectly secure, but we work to protect your information and will tell you if a breach affects you, as the law requires.

Changes

If we change this policy, we'll update the date at the top. If a change materially affects how we use your data, we'll tell you in the app before it takes effect.
