Backup
Your sessions are saved automatically on this device. Export a copy if you switch phones or clear your browser data. Export saves all your sessions as a .json file. Import adds the sessions from such a file; sessions you already have are skipped. Only the newest 1000 sessions are kept: if the total goes over 1000, the oldest sessions are removed.
