This Privacy Policy explains how the Duzz mobile application ("the App") handles your information. The App is developed by Patrik (hereafter "we", "us", or "the Developer").
The App does not collect, transmit, or store any personal data on our servers. Everything you create — workouts, training plans, exercise logs, body measurements, progress photos, and settings — is stored exclusively on your device using a local database (Android Room) and local preferences (DataStore). We operate no backend server, and your data, including your progress photos, never leaves your device.
Duzz includes an optional on-device AI workout generator. When you enable it, an AI model is downloaded once to your device and then runs entirely on your device, offline. Your inputs and the generated workouts are processed locally and are never sent to us or to any third-party server.
The App displays advertisements served by Google AdMob (including banner, interstitial, and opt-in rewarded ads). AdMob is a service of Google LLC and is subject to its own privacy policy. To serve ads, AdMob may automatically collect:
Full details: Google Privacy Policy · AdMob & AdSense Data Policy.

You can reset your choice at any time by resetting your Android Advertising ID (Android Settings → Google → Ads → "Reset advertising ID") or by reinstalling the App.
If you install the App from Google Play, Google Play collects data under its own policies: Google Play Policies.

com.google.android.gms.permission.AD_ID | Used by AdMob to serve ads |
When you tap "Share" on a workout or program, the App generates a text summary locally and opens Android's native share menu. The content is created on your device and sent exclusively to the target app you choose (WhatsApp, messaging, email, etc.). We do not receive a copy.
The App is not directed at children under 13. We do not knowingly collect data from children. AdMob is configured to not target content to children (COPPA).
Since we don't collect data, there is no data-breach risk from our side. Data on your device is protected by Android's security mechanisms (app sandbox).
Since we do not process personal data on our servers, GDPR rights of access, rectification, deletion, etc. do not apply to our operations. To exercise these rights regarding data processed by Google AdMob, refer to Google's policies.
At any time you can:
We may update this Policy over time. The last updated date is shown at the top. Material changes will be communicated through an in-app notice.
