Data retention
Your sessions are kept while your account is active, until you delete them.
Worsley keeps your sessions for as long as your account is active, so your trends and history stay complete. You can delete individual sessions or all of your sessions at any time.
A deleted session stays in Deleted Sessions in Settings for 30 days, so you can restore it, and is then erased for good. Deleting your account closes it at once, and after 30 days it's erased with everything in it.
Once erased, data may remain in backups for a limited time before they expire.
