Aetherglyph: Arcane Duels — Privacy Policy

Last updated: July 24, 2026. Publisher: Cooper Unlimited Games. Contact: rocmat21@gmail.com

Aetherglyph is a paid, one-time-purchase wizard dueling game. There are no accounts, no sign-in, no advertising, no in-app purchases, and no sale of personal data. This policy explains the small amount of data the game uses.

Anonymous identity

The game creates a random, anonymous identifier that is stored only on your device (browser/app local storage). It is not linked to your name, email, phone number, Google account, or any real-world identity. It is used to rank online matches and to reconnect to a duel after a brief disconnect. You may enter an optional display name; it is also stored locally and shown to opponents during a duel only.

Offline play

The tutorial and bot practice run entirely on your device and require no network connection. No data leaves your device during offline play.

Online play

When you start an online duel, the app connects to our authoritative game service (aetherglyph-server.onrender.com by default; you may configure a different service URL in Settings). To run a fair, server-authoritative match, the service processes:

• your anonymous identifier and optional display name;
• your selected guide shortcuts and the gestures/inputs you send during a match;
• network metadata inherent to any internet connection, including your IP address, used only for connectivity, security, abuse prevention, and short-lived connection logs;
• match results and a numeric skill rating tied to your anonymous identifier.

Raw gesture paths are used only to validate a cast and are then discarded. Connection/security logs are retained for a short period (up to 30 days) and then deleted. We do not use analytics SDKs, advertising SDKs, or third-party trackers.

Permissions

The Android app requests only the Internet permission (and network-state for connection quality). It does not request camera, microphone, location, contacts, photos, or broad storage access.

Data you control & deletion

Because your identity is anonymous and local, you can delete your data at any time:

• In the app: Settings → Delete my data removes your local identifier, display name, saved settings, and any saved duel token. A new anonymous id is created next time you play online.
• Server-side rating record: see the account & data deletion page to request deletion of the rating record associated with your anonymous id.

Children

The game contains fantasy magic combat and no chat. It is not directed at children under 13 and collects no personal information that would identify a child.
