1. Summary

Z-Sync has no servers of its own. The developer operates no backend, receives no analytics, and collects nothing for himself.
Your Mozilla sign-in happens directly on Mozilla's website inside the app. Credentials go to Mozilla only.
Sync content is encrypted on your device before it ever leaves it; Mozilla's servers store only ciphertext.
To display favicon previews, website domains are sent to DuckDuckGo's icon service. No account or personal data is attached.
All remaining data stays on your device: in the iOS Keychain and in the app's local storage.
Signing out or deleting the app removes that local data.
