What may stay on your device
Lien keeps core app data on-device where the product supports it. Some features may also use a backend for syncing, AI, account access, or asset delivery.
What may be sent when you use online features
If you use AI, sync, account, or delivery features, Lien sends the minimum data needed to power that feature to its backend and service providers. The exact data flow depends on the feature you use.
What we don't collect
We do not use ad SDKs, third-party trackers, or sell personal data. Payment details stay with Apple when you purchase through the App Store.
Purchases
If you buy a paid tier, Apple handles the transaction through StoreKit and shares only the purchase state needed to unlock the app's features.
Children
Lien is rated 4+ and does not knowingly collect any personal information from anyone, including children under 13.
