Swarmmail privacy policy

Last updated 10 November 2026

Swarmmail is a game you play with friends who open a room link. It has no accounts, no ads, no analytics and no tracking. This page says exactly what leaves your device and why.

What the game sends, and to whom

• Your nickname. The name you type (or the random one the game picks, like "Heron 27") is shown to the other players in your room. Do not use your real name if you would rather not.
• A random device token. A random code made on your device, so a room recognises you if your connection drops and you come back. It is not linked to you, your phone or any account.
• Game messages. While you play, your device exchanges game state (health, score, the monsters you mail) with the other players' devices.
• Your IP address is seen, as for any internet connection, by the room server and, when players connect directly to each other, by those players' devices and by a public STUN server (stun.l.google.com) that helps devices find each other.

What is stored

Nothing about you is stored on our side. The room server runs on Cloudflare. It relays messages while a room is open, keeps only a counter for numbering seats, and deletes that when the room empties. Request logging is switched off.

On your device the game keeps your nickname, the random token, your settings (sound, music, vibration, reduced motion) and which tips you have already seen. Clearing the app's data removes them.

What we never do

• No advertising, no analytics, no crash reporting services, no third-party SDKs.
• No selling or sharing of data. Cloudflare and the STUN server only carry traffic for the game.
• No location, contacts, camera, microphone or files are accessed.

Children

Swarmmail is not directed at children under 13 and does not knowingly collect information from them.

Changes and contact

If this policy changes, this page changes with a new date. Questions: write to the developer email shown on Swarmmail's Google Play page.
