Arch Rival - Privacy Policy

Last updated: July 4, 2026

Short version

Arch Rival does not collect, store, or share any personal information. There are no accounts, no analytics, and no advertising.

Information we do not collect

No name, email, phone number, or contact information.
No location data.
No device identifiers used for tracking or advertising.
No analytics or usage telemetry.
No third-party advertising SDKs.

Online multiplayer

When you play an online match, the app connects to our multiplayer relay server (hosted on PartyKit / Cloudflare) to exchange game moves between the two players in the same room. This exchange includes:

A short-lived 4-digit room code you or your opponent enters.
In-game moves (piece position, rotation, line clears, pause, game-over).

These messages are relayed in real time and are not persisted to any database after the match ends. IP addresses may be briefly visible to the relay infrastructure as a normal part of establishing a WebSocket connection; they are not logged or associated with any identity by the app.

Data storage on your device

The app stores your game preferences (sound, haptics, difficulty, volume) locally on your device only. This information never leaves your phone.

Children's privacy

The app does not knowingly collect information from anyone, including children under 13.

Changes to this policy

If this policy ever changes, the updated version will be posted here with a new "last updated" date.
