Recordings stay on this phone until uploaded directly to your Drive. Keep CamSync open while uploading.
CamSync creates this folder in your connected Google Drive.
Counted from each successful upload. Drive backups are kept. Applies to existing phone copies too; cleanup runs while CamSync is open or next reopened. Recordings waiting to upload are always kept.
Your recordings, settings, and upload history are stored on this phone. CamSync has no account database or application server. Only the backups you authorize go to Google Drive.
