Privacy Policy

Last updated: July 10, 2026

At Liniature, we respect your privacy. This Privacy Policy describes how we collect, store, and use information when you visit our website (liniature.com) and play our mobile game Stackle.

1. Information Collected Automatically

When you play Stackle, we do not require you to register with an email address or password. Instead, we collect the following anonymous data:

• Local Encrypted Saves: Your High Score, Lives remaining, ad removal status, and daily limits are saved locally on your device in an encrypted format. We use a hashed version of your device identifier (not raw IDs) solely for file encryption.
• Cloud Backup: We use Firebase Authentication to log you in anonymously. This generates a unique, random User ID (UID) to securely sync your save files to our database, protecting your progress if you switch devices.
• Analytics Data: We log anonymous events (such as game start, score milestone, or product purchase) to Firebase Analytics to understand game balancing and performance.
• Crash Diagnostics: We use Firebase Crashlytics to capture Stack Traces and error logs if the game crashes, helping us fix bugs quickly.

2. Third-Party Ad Services

We use Google AdMob to display banner, interstitial, and rewarded video ads. Google AdMob may collect and process device advertising IDs (e.g., Google ADID) to personalize ads and analyze traffic. You can reset these advertising IDs in your mobile device's settings menu at any time.

3. In-App Purchases

All purchases are processed securely by Google Play Billing. Liniature does not collect or store your payment card numbers, bank details, or personal billing addresses.

4. Security of Data

We protect your save data from modification and tampering:

• Local save files are encrypted using industry-standard AES-256 encryption.
• Cloud database access is protected by Firebase Security Rules, restricting read/write access exclusively to your authenticated UID.

5. Data Deletion

Since data is logged anonymously, you can clear all locally saved data at any time by clearing the application's storage or cache inside your device's application manager. To request deletion of any cloud backups associated with your anonymous ID, contact us at support@liniature.com.
