Session Sync Features

Cross-browser login sync, encrypted cookie backup, and selective controls designed to keep sessions portable without giving up security.

Real-Time Session Sync

Changes to your cookies are instantly synced across all connected browsers using secure WebSocket connections.

Cross-Browser Support

Works seamlessly with Chrome, Firefox, Edge, and other Chromium-based browsers on desktop and mobile.

Security-First Approach

No tracking, no analytics, no data selling. StayLogged only stores encrypted data you explicitly choose to sync.

Selective Sync

Choose which domains to sync using whitelist or blacklist modes. Full control over your synchronized sessions.

Security & Privacy

We take your security seriously. StayLogged is built with privacy as the default.

End-to-End Encryption

All cookie data is encrypted on your device using OPAQUE and VOPRF protocols before being uploaded. We never have access to your decryption keys, so only you can read your synced data.

Auditable Client

The browser extension client is open source and available for audit. Users can verify local encryption, key handling, and privacy-sensitive sync behavior without needing to trust opaque client code.
