Frequently asked questions
Where is my data stored?
Roster is a fully local app. All content stays exclusively on your device — there is no server and no cloud. Learn more in our privacy policy.
How can I delete my data?
You can delete individual entries directly in the app. If you want to remove all data, uninstall the app — this deletes all content stored locally on your device.
How do I manage my subscription?
Subscriptions are handled through your Apple ID. You can manage or cancel them anytime under Settings → [your name] → Subscriptions on your iPhone.
