Privacy Policy

Last updated: August 23, 2026

Silverback (“the app”, “we”) respects your privacy. This policy explains what data is processed when you use the app, and how. In short: your screen content stays on your phone;when product analytics is enabled, limited pseudonymous technical data is processed to improve the app.

Accessibility service and screen content

Silverback uses the Android Accessibility Service to understand when you are scrolling short videos (Reels, Shorts, TikTok). The service processes the foreground app package, whether a supported short-video surface is visible, and scrolling/index movement only on your device, in real time; the result is converted into a scroll count. Screen content is never stored, never sent to a server, never shared with third parties, and never sold.

Product analytics and technical diagnostics (PostHog, EU)

When product analytics is configured for the app build, PostHog receives a pseudonymous app/device identifier, app version, locale, device model, operating-system version, app interactions, and technical diagnostics. Accessibility-derived diagnostics are limited to the supported app package, aggregate swipe count, session duration, count strategy, and detection or overlay error signals. This data is used to improve counting reliability and investigate crashes; it is never used for advertising or sold.

Data kept on your device

Your scroll counts, limits, streaks, badges, and settings are kept in your device’s local storage. This data is removed from your device when you uninstall the app.

Invite codes (Google Play Install Referrer)

If you install the app from a friend’s invite link (silverback.app/i/<code>), only the invite code (code=<CODE>) is passed to the app via the Google Play Install Referrer, so you join the right battle.

Battles and friend challenges

When you sign in with Google and join a battle, your account ID, display name, profile-photo URL, daily aggregate swipe score, earned badges, and friend/invite state are processed in Supabase. This data is visible only as required by Battle and your friend relationships. The rest of the app works without an account.

Feedback and purchases

If you submit feedback in the app, we send the category, message you write, app version, platform, and, if signed in, your Battle account ID to Supabase. If you subscribe or restore a purchase, RevenueCat and Google Play process the purchase status and identifiers needed to provide entitlement; we do not receive payment-card details.

What we do not collect

Third-party services

We share data only with processors needed for the features described: PostHog (analytics and diagnostics), Supabase (Battle and feedback), Google (sign-in and Play services), RevenueCat (subscription management), and Google Play (purchases). See theGoogle Privacy Policy for Google’s own data practices.

Retention and deletion

Local data is removed when you uninstall the app or clear its storage. You can sign out of Battle at any time. To permanently delete a Battle account and its related cloud records, use the in-app account-deletion option or contact us at the email below.

Children

Silverback is not directed to children under 13 and does not knowingly collect data from them.

Changes

We may update this policy from time to time. For material changes we update the date on this page.
