Privacy Policy

Effective date: 2026-05-11

Attack Deck ("the app") is published by 30str ("we", "us"). This policy describes what data the app handles and how.

Summary

Attack Deck collects nothing. No account, no telemetry, no analytics, no crash reporting, no advertising. The app does not connect to any of our servers. Everything you do in the app stays on your device.

What is stored on your device

Attack Deck uses your device's local storage (via AsyncStorage on iOS and Android) to remember:

  • The characters you have added (name and chosen class).
  • The perks you have toggled on each character.
  • The current state of each character's attack modifier deck (drawn, discarded, etc.).
  • Your settings (language preference, haptic feedback toggle, list of revealed classes).

This information never leaves your device and is not transmitted to us or to any third party. Deleting the app from your device deletes all of this data.

What we do not collect

  • We do not collect personal information.
  • We do not use analytics, telemetry, or crash reporting tools.
  • We do not show advertising.
  • We do not use any third-party tracking SDKs.
  • We do not request location, contacts, camera, microphone, or any other system permission beyond local storage and haptic feedback.

Third-party services

The app does not integrate with any third-party service that processes user data.

The game data shipped with the app (class names, perks, attack modifier deck composition) is adapted from the open-source Gloomhaven Secretariat project. That data is bundled with the app and used offline.

Children

The app is appropriate for all ages and is rated accordingly. It does not collect data from anyone, including children.

Changes to this policy

If we change this policy, we will update the effective date above and post the updated version at the same URL. Material changes will be announced in the app's release notes.
