Privacy Policy
Last updated: October 25, 2026
Overview
Tessera ("the App") is developed and maintained by LL Cloud Development & Operations ("we", "us", "our"). We are committed to protecting your privacy. This policy explains what data the App accesses, how it is used, and your rights.
Data We Collect
Tessera does not collect personally identifiable information. No account, email, or sign-in is required to use the App.
Your wallpapers, settings, favorites and library stay on your device. The App collects a small amount of anonymous technical data through the services below:
- Usage analytics (Google Firebase Analytics): anonymous product events, such as a wallpaper being applied or a filter being used, with the phone maker, Android version and app version, so we can see which features work. No advertising ID is used.
- Crash reports (Sentry): in release builds, if the App crashes, a technical report with the stack trace, device model and app version is sent so we can fix it.
We do not use advertising identifiers, advertising SDKs, or any form of tracking across apps.
Network Requests
To deliver fresh curated artwork, the App makes the following network requests:
Catalog & Image Downloads
The App fetches a curated daily catalog and the artwork files themselves from our server at llcloud.app. These requests carry only the standard HTTP information (your IP address, User-Agent) needed to deliver the response. We do not log this information for analytics.
Popularity Ping
When you apply a wallpaper from our daily catalog, the App notifies the server which artwork was used so we can surface popular pieces over time. The ping contains only the artwork identifier — no user identifier, location, or device data is sent.
Museum APIs (Pro)
Pro users can browse beyond the daily curation by querying participating museum open-access APIs directly. These requests are anonymous and follow each museum's public terms of service. No identifier is attached.
Permissions & How They Are Used
The App requests Android permissions only as needed to deliver wallpaper functionality:
Set Wallpaper
Used to apply the chosen artwork to your home and lock screen via Android's WallpaperManager.
Internet Access
Used to download artwork from our catalog and museum APIs. No background data sync happens beyond fetching wallpapers on the schedule you choose.
In-App Purchases
Pro features are available as a one-time purchase processed through the Google Play Store. The purchase transaction is handled entirely by Google. We use RevenueCat to verify purchase entitlements. No payment information is accessed or stored by the App. RevenueCat receives an anonymous app user ID; no personally identifiable information is shared. See RevenueCat's Privacy Policy for details.
Local Storage
Your settings, favourites, history, applied-config preferences, and cached artwork are stored locally on your device using Proto DataStore and the standard Android file cache. None of this data is transmitted off your device and it is deleted when you uninstall the App.
Third-Party Services
- Google Play Store: app distribution and in-app purchase processing
- RevenueCat: purchase entitlement verification (anonymous user ID only)
- llcloud.app servers: daily catalog and artwork delivery
- Museum open-access APIs: catalog artwork browsing (Pro)

Children's Privacy
The App is not directed at children and does not knowingly collect personal data from anyone. The technical data described above is anonymous and is not used to identify you.
Changes to This Policy
We may update this privacy policy from time to time. Changes will be reflected on this page with an updated date. Continued use of the App after changes constitutes acceptance of the revised policy.
