No account, no login, no ads, no tracking.

Rivals ("the app", bundle com.ludovicpuaud.rivals) is published by Ludovic Puaud. This page says exactly what leaves your device and why.

What the app collects

Product interaction — which screens are used, which choices are made in the game, whether a purchase screen was seen. Sent to PostHog (EU servers) keyed to a random identifier created on first launch. It is not linked to your name, email, contacts or any account, because the app has none. You can rotate it at any time: Settings → Reset my anonymous ID.
Purchase history — processed by RevenueCat and Apple so a purchase can be restored on a new device. Not linked to an identity; not used for tracking.
Messages you write in Settings → Message the developer, with the app version and device model, and an email address only if you type one.

What it does not collect

No name, email, contacts, location, photos, microphone, advertising identifier, or anything from other apps. There is no advertising SDK, so the app never asks for App Tracking Transparency permission. Your runs, ledger and settings stay on your device unless you export them yourself.

Notifications

Local only, scheduled on the device, never from a server. At most one reminder when a run is left unfinished, and an optional daily reminder you turn on yourself.

Children

The app is rated 12+ and collects no personal information from anyone.

Your rights

Because nothing identifies you, there is nothing to look up or delete beyond the pseudonymous analytics stream, which you can unlink with the reset in Settings. Questions: matcontact@tuta.io.
