A WHITE BELT'S GUIDE TO JIU JITSU
- PRIVACY POLICY

(c) Cyber Fitness - Discipline Rewired (CFDR). Last reviewed: October 2026.

A White Belt's Guide To Jiu Jitsu is made by Cyber Fitness - Discipline Rewired (CFDR). We keep things simple: the notes and progress you create stay on your own device, and we do not run our own servers or collect personal information from you.

What the app stores

Your favourites, notes, questions, scrapbook entries, goals, skill ratings and whether you have removed ads are saved only in local storage on your device. This data stays on your device, is not sent to us, and is removed if you uninstall the app or clear its data.

Ads

Until you remove ads, the app shows advertising through Google AdMob. To serve ads, Google and its partners may collect and use data such as your device's advertising identifier, approximate location and app usage, under Google's own privacy policy at policies.google.com/privacy. You can manage ad personalisation in your device settings. Removing ads with the in-app purchase stops ads from loading.

Purchases

The optional "Remove all ads" purchase is handled by the Google Play Store or the Apple App Store. We never see or store your payment details; the store processes the transaction under its own privacy policy.

Links to other services

The app can open YouTube to show technique videos. Once you leave the app, the privacy policy of that service applies, not this one.

Children

The app is a general reference and is not directed at children under 13, and we do not knowingly collect personal information from anyone.

Changes

If this policy changes, the updated version will appear here in the app.
