Jump Rope Coach — Privacy Policy
Last updated: September 27, 2026
This policy explains what data Jump Rope Coach ("the app") handles. The app is published by The Alchemist Code ("we").
The short version
- There is no account. We never ask for your name, email or password.
- Your workouts, history, progress and settings are stored only on your device. We do not upload them anywhere.
- The app shows ads and uses analytics and crash reporting. Those services, run by Google and RevenueCat, collect some technical data, described below.
Data stored on your device
Workout sessions, progress, custom workouts, unlocks and settings. They stay on your phone. You can erase them at any time in Settings › Delete my data. Uninstalling the app also removes them.
Data collected by third-party services
| Service | What it collects | Why |
|---|---|---|
| Google AdMob (ads) | IP address (used to estimate approximate location), Android advertising ID and app set ID, interactions with ads and the app, performance diagnostics | Showing ads, measuring them, preventing fraud |
| Google Analytics for Firebase | App-instance ID, advertising ID, approximate location derived from a masked IP address, screen views, sessions and purchase events | Understanding how the app is used |
| Firebase Crashlytics | Crash stack traces, device metadata at the time of a crash, app state, an installation identifier | Finding and fixing crashes |
| Firebase Remote Config | Country, language, time zone, OS and app version | Adjusting app settings remotely |
| RevenueCat | Purchase history and an anonymous app user ID | Managing your subscription |
| Google Play Billing | Payment details | Processing purchases (we never see your card) |
All of this data is encrypted in transit. Each provider handles it under its own privacy policy:
- Google: https://policies.google.com/privacy
- How Google uses data from apps that use its services: https://policies.google.com/technologies/partner-sites
- RevenueCat: https://www.revenuecat.com/privacy
Your choices
- Ad personalization (EEA, UK, Switzerland): the app asks for your consent before showing personalized ads, and you can change your choice anytime in Settings › Ad privacy options.
- Advertising ID: you can reset or delete it in your Android settings under Privacy › Ads.
- Premium removes all ads.
Children
The app is not directed at children under 13 and we do not knowingly collect data from them.
