Stoic doesn’t use accounts in a traditional sense. Everything you write stays tied to your device and your Apple ID. There’s no cloud account to recover or manage — everything remains 100% private to you.
If you delete stoic from your devices, your data will be deleted along with it. Therefore, before deleting the app, be sure to export your journals and data. To read more about data exporting and backups, go to Data Storing, Importing & Backups section of this Help Center.
