BodyLoop: Body & Waist Tracker · Last updated November 6, 2026

BodyLoop is made by Digital Utopia SRL (Romania). It has no accounts and does not ask for your name or email. We do not sell your information, share it for advertising, or track you across other apps or websites. There are no ads.

What stays on your phone

Your weigh-ins, waist and biceps measurements, height, target weight, units, goal, reminders and progress photos are stored on your iPhone. Progress photos are kept inside the app and are not saved to your Photos library. If you allow Apple Health, the app reads your steps, active energy and walking distance to show them; it does not write to Health and does not send this data anywhere. You can export a backup file and import it again at any time. Deleting the app deletes this data.

Personal answers from the AI coach

The coach can use your progress only if you allow it. The app asks once, the first time you open the coach, and you can change your choice at any time in Settings. When it's on, each new message to the coach carries a short summary from BodyLoop: your goal, target weight, units, your first and latest weigh-ins with their dates, weekly averages, waist measurements, your trend and the estimated date for your goal. Settings shows what would be sent. The summary is passed to OpenAI to write that answer and is not stored by us. When it's off, nothing of this is sent and the coach answers in general terms. Photos are never sent.

The coach is an AI. Its answers can be wrong and are not medical advice; see the Terms of Use.

Usage statistics

The app records a few moments, such as opening the app, finishing onboarding, logging a measurement (never its value), opening the paywall, sending a message to the coach (never its text) and your choice about personal coach answers. They are sent with a random ID that iOS creates for our apps on your phone, the app version and your time zone offset. The app never reads your advertising identifier. Our server (Heroku and MongoDB Atlas, United States) keeps the statistics for one year and uses them only in totals. Google Firebase Analytics and Crashlytics collect similar usage data and crash reports under Google's terms.

Legal basis (GDPR)

The coach and purchases: to provide the service you asked for (Art. 6(1)(b)). Personal coach answers: your consent, which you can withdraw in Settings at any time (Art. 6(1)(a) and 9(2)(a)). Statistics, crash reports and onboarding answers: our legitimate interest in keeping the app working and improving it (Art. 6(1)(f)); you can object by writing to us. Transfers to the United States rely on the EU-US Data Privacy Framework or Standard Contractual Clauses.

Your rights

Wherever you live, you can ask us whether we hold information about you, for a copy, or to correct or delete it, free of charge. Because we don't know who you are, tell us the date and approximate time of a conversation or send the feedback email you used, so we can find it. We reply within one month. You can also complain to your data protection authority. California and other US states: we do not sell or share personal information and do no targeted advertising.

Children

BodyLoop is not directed at children under 13, and we don't knowingly collect their information.

Changes

If this policy changes, the new version appears here with a new date. If a change would send something new off your phone, we'll say so in the app first.
