POWER Privacy Policy

Last updated: October 16, 2026

YOTATIS MANGNIMIT (the "Provider") sets out below how information is handled in the iPhone application "POWER" (the "App").

In short
No account is required, and your workout records and profile are stored only on your device. Meal text and photos you enter, and the figures used for the coach's feedback, are sent through the Provider's server to an external analysis service to estimate nutrition and generate wording; only an anonymous ID accompanies them and photos are not stored (see "7. Data sent by Meals and Coach"). To serve ads, Google AdMob may collect advertising identifiers (see "5. Advertising"). If you link Apple Health, Health data is used only on your device (see "8. Apple Health"). Cheers send your nickname and the body part you are training (see "9. Data sent by Cheers").

1. Information we do not collect

The Provider does not collect your name, email address, location or contacts. Photos you choose to submit in Meals are used only for analysis and are not stored (see "7. Data sent by Meals and Coach"). Information obtained in connection with advertising is collected by a third party (Google) as described in "5. Advertising".

2. Information stored on your device

The following is stored only within the App's own storage on your device (SwiftData and UserDefaults). The Provider has no access to it.

Workout records (date, exercise, weight, reps, duration, distance, notes)
Profile (nickname, sex, birth year, body weight, height, goal, focus body part, training experience and location)
Meal records (food name, amount, calories, nutrients), body weight and body fat log, water / bowel / supplement records, and goal-weight / diet-style settings
Coach settings (chosen coach, monthly goal and schedule answers, reminder frequency) and the coach's feedback and report text
App settings (display mode, language, units, colors, notification preferences)
Progress state such as level, EXP, titles and streaks, and what the coach has remembered ("Coach memory", which you can review and delete in Settings)
A summary for the widgets (level, streak, last 7 days, etc.), kept in the App's shared storage on the same device; nothing is transmitted

Deleting the App removes this data from your device. To move it to a new phone, use "Export data" / "Import data" in Settings. You are responsible for the exported file.

3. Purchases

Subscription purchase, renewal and restoration are handled through Apple's App Store. The Provider only checks on-device whether a subscription is active, and never receives payment details such as card numbers. Payment information is handled under Apple's Privacy Policy.

4. Notifications

The App uses local notifications (generated on your device) for the purposes below. They are delivered only if you allow them; no push notifications are sent from external servers. You can turn them off at any time in iOS Settings or in the App.

A reminder on days when your streak is at risk
A reminder before the free trial ends (2 or 3 days before, your choice)
A check-in from your coach 24 and 72 hours after your first logged workout
A reminder from your coach on the training days you selected
The end of the rest timer (the remaining time shown on the Lock Screen as a Live Activity is also generated on the device; no server updates)
The coach report every Monday
Supplement / medication times you set

5. Advertising

The App uses Google AdMob (Google LLC) for rewarded-video ads that unlock certain features. To serve ads, prevent fraud and cap ad frequency, Google may collect your device's advertising identifier (IDFA), IP address and device information. Such data is handled under Google's Privacy Policy and Google's partner sites policy.

If you choose "Ask App Not to Track" (App Tracking Transparency), the advertising identifier is not used and non-personalized ads are shown instead. All features of the App remain available either way. You can change this at any time in iOS Settings > Privacy & Security > Tracking.

Premium and higher plans do not require watching ads to unlock features.

6. Usage analytics

To improve the App, anonymous usage data is sent to the Provider's server (Supabase). This covers which screens were opened, which buttons were tapped, where a tutorial was abandoned, plus the app and OS version.

The only identifier used is a random anonymous ID generated inside the App on first launch. No device identifier (such as IDFA), name or email address is used. The ID is lost when the App is deleted and cannot be matched with data from other services.

The contents of your workout records (weights, reps, notes, profile) are never sent. They remain on your device.

7. Data sent by Meals and Coach

Meal text and photos you enter, questions you ask the coach (Pro), and the facts used for the coach's feedback and reports (that day's exercise names, set counts, whether a personal best was set, body weight and goal figures, and your monthly goal and schedule answers), are sent through the Provider's server (Supabase) to an external analysis service (Anthropic, PBC) to estimate nutrition and generate wording.

The only identifier attached is the same random anonymous ID described in "6. Usage analytics"; it is not linked to your name, email address or advertising identifier.
Photos are downscaled, used only for analysis and not stored afterwards. The resulting figures are kept only on your device.
Common foods are matched against a database inside the App and are never sent. For the same text input, the resulting food name and nutrition figures may be kept in a shared cache so the analysis need not be repeated; who entered it is not recorded.
To enforce usage limits, the Provider's server counts the number of analyses per anonymous ID.
Questions you ask the coach and the answers are used only to generate the reply and are not stored on the Provider's server; the history is kept only on your device.
Handling by the external service is governed by Anthropic's Privacy Policy. The Provider uses a commercial API under which submitted data is not used to train models.

If you do not use Meals or the Coach, none of this data is sent.

8. Apple Health

Only if you turn it on, the App exchanges the following with iOS Health (HealthKit):

Reads: body weight (e.g. recorded by a scale app) and step count
Writes: workouts (strength training with active energy), meal calories and nutrients, and body weight

Data read from Health is used only for the App's own features, such as calculating your calorie target and the "Activity" tile, and is stored on your device. Health data is never sent to the Provider's server, to advertising partners or to external analysis services, and is never used for advertising or marketing. You can turn the link off at any time in Settings, and records written to Health can be deleted in the iOS Health app.

9. Data sent by Cheers (community beta)

To show how many people are training right now and to exchange cheers, from the moment you log the first exercise of a session until you finish, the App sends a random anonymous ID (the same one described in "6. Usage analytics"), the body part you are training, the App language and the nickname from your profile to the Provider's server (Supabase). Your nickname is shown to the people who receive your cheer (no real name is required). The contents of your workout (weights, reps, notes) are not sent. When you finish, the "training now" record is deleted from the server.

10. Sharing with third parties

The Provider does not share or sell your information to third parties. The transmission to the external analysis service described in "7. Data sent by Meals and Coach" is processing on the Provider's behalf, not a sale or sharing.

11. Children

The App is not directed at any specific age group and does not knowingly collect information from children under 13.

12. Changes to this policy

This policy may be updated as laws or features change. Updates take effect when posted on this page.
