Data protection policy

Who is responsible

the Calorific developer is the controller of the personal data described here. Write to us from Settings > Report a problem and choose "I'd like a reply".

What we collect

Account: your email address and name, or the details Sign in with Apple gives us (which may be a private relay address), and when you joined.

Food and body: the meals you log (text, calories, nutrients, and meal photos), your calorie and macro goals, your weight and body details such as age, sex, height, activity level, and anything you choose to tell us about health conditions or injuries. Some of this is health information, which the law treats as special category data.

Training: your plans, workouts, sets, cardio details (distance, pace, and optional weather and a town name), schedule changes, and daily check-ins such as energy, soreness, sleep and mood.

Progress photos: kept on your device unless you choose "Keep my photos on my account", in which case an encrypted copy is stored for you.

Apple Health: if you connect it, the app reads the items you allow (for example steps, activity, sleep, weight and heart rate) on your device, and writes workouts and nutrition you save. What the app reads from Health stays on your device unless you separately choose to save it to your account.

Time zone, so that "today" is the right day wherever you are. Your exact location is never stored or sent; weather lookups use a position rounded to about a kilometre, only when you ask.

Problem reports you send, with the app version, device model and system version.

Why we use it, and our legal basis

To run the app for you, which is our contract with you: syncing your log across devices, calculating your targets, and producing plans and reviews.

Health information is used only with your explicit consent, which you give when you create your account and set up your profile. You can withdraw it at any time by deleting the information in the app or deleting your account; the parts of the app that need it will then stop working.

To keep the service safe and fix faults, which is our legitimate interest.

We do not sell your data and we do not use it for advertising.

AI services

To analyse meals and write plans and reviews, we send the relevant text, meal photos and a limited set of body and training details (for example age, sex, height, weight, goal, injuries and recent training averages) to an AI service provider. We use Anthropic's Claude, and may use other providers on the same terms. We choose providers that do not train their models on this data by default.

Photos sent for a one-off analysis are not stored by us. The provider may keep inputs for a short period under its own terms. Progress photos are read by an AI service only when you ask for a comparison and have separately allowed it.

Free-text notes you write (such as check-in notes) are not sent.

Where it is kept and how it is protected

Your data is stored on a server we run. It is encrypted in transit. Health information, progress photos, meal photos and problem reports are also encrypted at rest. Access is limited to what is needed to run the service.

Nightly backups are kept for up to 14 days, so deleted data can remain in a backup for that long before it ages out.

How long we keep it

We keep your data until you delete it or your account. Problem reports are deleted after 12 months. Deleting your account removes your records from our systems straight away, apart from backups as described above.

Your rights

You can ask to see or export what we hold about you, correct it, delete it, restrict or object to its use, and withdraw consent. Most of this you can do yourself in the app: edit your details, delete entries, withdraw photo consent, and permanently delete your account in Settings.

For anything else, Write to us from Settings > Report a problem and choose "I'd like a reply". You also have the right to complain to the data protection authority in your country; in the UK that is the Information Commissioner's Office (ico.org.uk).

Children

Calorific is not for children under 13 and we do not knowingly collect their data. If you are under 18, please use the app with a parent or guardian's agreement. For under-18s the app avoids weight-loss targets and weight talk.

Changes

If this policy changes in a way that matters, the app will show you the new version and ask you to accept it again.
