Privacy policy

Effective October 10, 2026. Tower Blocks is operated by Velvin Technologies Private Limited.

No sign-in

Tower Blocks has no accounts and never asks for your name, email address or password. Each installation creates a random anonymous player identifier and a random device key, stored encrypted on your phone using Android Keystore.

What we store

For that anonymous player we store your unlocked cities and the towers built in them, your best scores and heights in each mode, and your settings for World Tour, when the player was last active, and a support code shown in Settings. We use this to keep your progress safe and to restore it on another phone. Sound and music preferences stay on your phone.

Google Play Games

If you are signed in to Google Play Games, the game uses Google's Play Games Recall service so your progress follows your Play Games profile. We send Google an encrypted token and an opaque identifier for your anonymous player; neither contains personal information. Google never shares your Play Games identity with us. You can manage or remove these links in your Play Games settings. Google processes this data under the Google privacy policy.

Services and security

Convex hosts the game backend. Network requests also expose connection information such as IP addresses to service providers. Cloud communication uses HTTPS. We do not sell personal information. This version has no purchases or remote gameplay analytics.

Advertising

Tower Blocks shows ads from Google AdMob: a full-screen ad at some breaks between games, and an optional ad you can choose to watch to keep building after a fall. The Google Mobile Ads SDK collects device identifiers such as the advertising ID, approximate location derived from your IP address, and ad interactions, and shares them with Google to serve and measure ads. Where the law requires it (for example in the EEA, UK and Switzerland) the game asks for your consent first, and you can change your choice at any time in Settings → Privacy and ad choices. Learn more in how Google uses information from sites or apps that use its services.

Retention and deletion

Progress is kept until you delete it, or automatically deleted after 12 months without playing. Use Delete my progress in the app's Settings, or the web deletion page with the support code from Settings. Deletion removes the player, saved game and every device key, and removes the Play Games link when the app can reach Play Games. Service providers may temporarily retain backups or operational logs under their retention policies. Convex dashboard backups, if enabled, expire after 7 days for manual/daily backups and 14 days for weekly backups. Uninstalling the app or clearing its storage removes local game data.

Service policies

Convex privacy policy and Google privacy policy explain provider practices. Data may be processed outside your country.
