SyncMarket is a privacy-first browser extension for tracking marketplace listing views and metrics.

1. Local Data: All scans, view histories, and metrics are stored locally on your device via IndexedDB. No account or remote connection is required for core functionality.
2. Optional Cloud Sync: Users who opt into cloud sync sign in with Firebase. Synced data is restricted to their authenticated user account for backup and multi-device restoration.
3. No Tracking / Ads: We do not sell data, run tracking analytics, or serve ads.
4. Licensing: Lifetime Pro license validation verifies purchases via Gumroad API without storing payment details.
