Rival Brains — Privacy Policy

Effective date: July 25, 2026

Rival Brains is a two-player game played on one phone, published by Proliferaite LLC. It has no accounts, no sign-in, and no servers of its own.

What stays on your device (everything you create)

Player names, emoji, avatar photos, scores, head-to-head records, and settings are stored only on your device. They are never uploaded, transmitted, or shared. Avatar photos taken with the camera or chosen from your gallery are copied into the app's private storage on the device and nowhere else. Uninstalling the app permanently deletes all of this data.

What is collected automatically (diagnostics only)

To find and fix crashes, the app uses Google Firebase Crashlytics and Firebase Analytics. When the app runs, Google's SDKs may collect:

• Crash logs and stack traces
• Diagnostics: device model, operating system version, app version
• Anonymized identifiers (such as a Firebase installation ID) used to count installs and de-duplicate crash reports

This information is used solely to keep the app working and is processed by Google LLC on our behalf. It is encrypted in transit. Crash data is retained by Google for a limited period (approximately 90 days) and then deleted. We do not use this data for advertising and we do not sell it.

Advertising

The current version of Rival Brains shows no ads. If a future version introduces ads, this policy and the app's store listing will be updated first.

Children

Rival Brains is suitable for a general audience. We do not knowingly collect personal information from anyone, including children — the only data that leaves the device is the anonymous diagnostics described above.

Data deletion

All gameplay data lives on your device: uninstalling the app deletes it. Diagnostic data held by Google expires automatically. For any request or question, contact us at the address below.

Changes

We will post any changes to this policy at this URL and update the effective date above.
