This Privacy Policy describes how Telestai Foundation ("we," "our," or "us") collects, uses, stores, and protects information when you use our mobile applications: Zeroa and LASKO (collectively, the "Apps").

We are committed to protecting your privacy and ensuring transparency about our data practices. This policy applies to both iOS and Android versions of our Apps.

2. How We Use Your Information

• Error Monitoring: Analyze anonymized error logs to fix bugs and improve stability
• Security: Detect and prevent security threats

3. How We Store Your Information

3.1 Local Storage

Sensitive Data (Stored Locally Only):

• Private Keys: Encrypted and stored in iOS Keychain or Android Keystore (never transmitted)
• Mnemonic Phrases: Encrypted and stored in iOS Keychain or Android Keystore (never transmitted)
• Wallet Addresses: Stored locally on your device

Profile Data: Display names and profile images stored in App Groups (shared between Zeroa and LASKO on the same device). Data remains on your device and is not transmitted to our servers.

3.2 Remote Storage

Anonymized Logs: Error logs and diagnostic information are sent to our servers at halo.telestai.io. Logs are anonymized and do not contain private keys, full mnemonic phrases, full wallet addresses, or personal identifying information. Logs are retained for up to 7 days for debugging purposes.

4. Information Sharing and Disclosure

We never sell, rent, or trade your personal information to third parties.

Zeroa and LASKO share profile information (display name, profile image) through iOS App Groups or Android SharedPreferences. This sharing occurs only on your device and is not transmitted externally.

5. Your Rights and Choices

You have the right to:

• Access your data stored locally on your device
• Delete your local data by uninstalling the Apps or clearing app data
• Control profile information through app settings
• Export your wallet using your mnemonic phrase

Note: Deleting the Apps will remove all locally stored data, including private keys and mnemonics. Ensure you have backed up your mnemonic phrase before deletion, as we cannot recover lost wallets.

6. Security Measures

• Encryption: Private keys encrypted using iOS Keychain or Android Keystore (hardware-backed when available)
• Access Controls: Private keys never leave your device unencrypted
• No Server-Side Storage: We do not store private keys or mnemonics on our servers

7. Children's Privacy

Our Apps are not intended for children under the age of 13 (or the minimum age in your jurisdiction). We do not knowingly collect personal information from children.
