2. What we do not collect
- We never see or store your payment card details. Purchases are handled entirely by Google Play.
- We do not collect your contacts, photos, files, precise GPS location, microphone or camera data.
- We do not ask for your real name, postal address, or date of birth.
- We do not sell your personal information, and we do not share it with data brokers or advertising networks.
3. Service providers
We rely on a small number of Google services to operate the Game. These providers process data on our behalf; we do not sell your data, and we do not share it with advertising networks or data brokers.
- Google Play Billing — processes purchases. Google’s own privacy policy applies to the payment itself.
- Google Sign-In / Firebase Authentication — used only if you choose to link your Google account.
- Firebase Cloud Messaging — delivers push notifications.
- Google Analytics for Firebase — measures how the Game is used, so we can see which features are played and where players get stuck. It records an app-instance identifier (a random ID for your installation, reset if you reinstall or clear the app's data), basic device and country information, and in-game events such as launching the Game or completing a level. It does not record your name or email address.
Google’s handling of this data is governed by the Google Privacy Policy.
Aside from the providers listed above, the Game does not send your data to any other third party.
4. Where data is stored
Game data is stored on servers operated by or for the Developer. Data sent to Google services is handled on Google’s infrastructure under their terms.
5. How long we keep it
- Game accounts and progress — kept while the account is in use, and for a reasonable period afterwards so you can return to your characters.
- Chat messages — retained only for a limited period for moderation and abuse handling.
- Technical logs — kept for a short period for security and diagnostics.
- Purchase records — kept as long as required for accounting and dispute handling.
If the Game is permanently shut down, player data will be deleted within a reasonable period after the shutdown.

Email [email protected] with the subject line
Data deletion, and include your in-game character name and server, or the Google account you linked. We will confirm and complete the request within 30 days.
Please note that deleting your account permanently removes your characters, progress, and any unused virtual items. This cannot be undone, and purchases are not refundable on deletion.
7. Children
The Game is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us with personal information, contact us and we will delete it.
8. Security
We take reasonable technical measures to protect player data, including signed requests between the Game and our servers. No system is perfectly secure, and we cannot guarantee absolute security. If a breach affects your data, we will notify affected players and the relevant authorities where the law requires it.
9. Changes to this policy
If this policy changes in a way that materially affects you, we will update the effective date above and announce the change in the Game before it takes effect.
