Privacy Policy

Last updated: August 2026

1. Controller

This app (Habituo – Habit Tracker) is operated privately.
Contact: klaus.workk@gmail.com

2. Local data (stays on your device)

Habituo is designed for maximum privacy. Your habit-tracking data stays exclusively on your device.

• Habits, tasks, goals: Stored only locally on your device. Never transmitted to servers.
• Body data (weight, photos): Stored locally only. Photos never leave your device.
• Settings (language, dark mode): Stored locally.

3. Account & Friends (optional)

Habituo works fully without an account. If you choose to sign in with "Sign in with Apple" to add friends and appear on leaderboards, we process data for this via our backend provider Supabase (server location EU/Frankfurt):

• An anonymous user identifier provided by Apple (no email address, no real Apple ID)
• Your self-chosen username and friend code
• Level, streak, success rate, and count of active habits (not the habits themselves or their content)
• A country roughly derived from your device language (no GPS, no precise location)
• Friend requests and any reports/blocks you create, if you use those features

This data is visible to friends and/or on public leaderboards if you opt in ("Visibility" toggle in settings). You can delete your account, including all server-side data, at any time directly in the app (Profile → Delete Account). Your local on-device habit data is not affected by this.

4. Advertising (Google AdMob)

In the Shop, you can optionally watch short video ads to earn coins. We use Google AdMob for this. We only request non-personalized ads — there is no cross-app tracking. Google may still process technical data for ad delivery, fraud prevention, and frequency capping (e.g. a device identifier, IP address, approximate location).

Users in the EEA, UK, and Switzerland see a consent prompt on first launch (Google User Messaging Platform). You can change your choice at any time under Settings → "Ad preferences". Google Privacy Policy: policies.google.com/privacy

5. In-App Purchases (RevenueCat)

When you purchase Habituo Pro or coin packs, we use RevenueCat to process purchases. RevenueCat processes:

• Device ID (anonymized)
• Purchase history (via Apple)
• App version and platform

RevenueCat Privacy Policy: revenuecat.com/privacy

Payment data (credit card, etc.) is processed exclusively by Apple (App Store). We never see your payment details.

6. No general tracking

Habituo contains no analytics or tracking SDK and builds no cross-app advertising profiles. We do not sell data to third parties. The only exception is the data processing technically required for ad delivery via Google AdMob (see section 4).

7. Photo access

The Body feature can optionally use photos from your photo library. Permission is only requested when you actively choose to add a photo. Photos are stored locally and never transmitted.

8. Data storage & deletion

Your habit-tracking data is stored in your device's local app storage. You can delete it at any time by:

• Uninstalling the app
• Deleting app data in device settings

You can delete server-side account data (see section 3) at any time via the app (Profile → Delete Account). Deletion is irreversible.

9. Children

Habituo is not directed at children under 13. We do not knowingly collect personal data from children under 13.

10. Reporting & blocking

Within the social features (friends, leaderboards), you can block other users or report them for inappropriate behavior. Blocked users can no longer see you and you can no longer see them. Reports are stored for review.

11. Changes to this policy

We may occasionally update this privacy policy. The date of the last change is shown at the top of this page.
