MONSTER VAULT

Privacy Policy

Last updated: November 5, 2026

Monster Vault is a monster card collecting game for Android. This policy explains what information the game collects, why, and how you can delete it. The short version: we collect only what is needed to save your progress, we never sell it, and you can delete everything at any time.

What we collect

• A random account ID. When you first open the game, it creates a guest account so your progress can be backed up. This ID is not linked to your name or device.
• Your email address, only if you choose to save your account. It is used to send you a sign-in code and to let you load your save on another phone. We do not send marketing emails.
• Game data. Your collection, currencies, levels, settings and the results of pack openings, battles and gradings. This is stored so your progress is not lost and so the game's economy cannot be cheated.

The game does not collect your location, contacts, photos, advertising ID, or payment information. Version 1 has no ads and no in-app purchases.

How it is used

Only to run the game: saving and restoring your progress, signing you in, and checking that rewards and purchases inside the game follow its rules. We do not sell or share your information with anyone for advertising.

Where it is stored

Game data is stored with Supabase, our database and sign-in provider, and on your own phone. Sign-in emails are sent through our email provider. These providers process data only on our behalf. Data is encrypted in transit.

How long we keep it

Until you delete your account. If you delete it, your account, email address, collection and save are permanently erased from our servers.

Deleting your account

In the game, open Settings → Account → Delete account. This erases everything immediately. If you no longer have the game installed, see how to request deletion.

Children

Monster Vault is not directed at children under 13, and we do not knowingly collect information from them. If you believe a child under 13 has given us their email, contact us and we will delete it.

Changes

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