Need help with Fastum, or have a question or idea? We’d love to hear from you.
How do I manage or cancel my subscription?
Open the App Store app, tap your profile, then Subscriptions, and choose Fastum. You can change or cancel there. Note: deleting the app does not cancel a subscription.
Where is my fasting data stored?
In your Fastum account, synced securely to our backend so it's available across your devices. To remove it, use Clear history in the app, or delete your account entirely from Me → Delete Account.
My notifications aren’t showing up.
Make sure notifications are allowed for Fastum in your device Settings → Notifications → Fastum, and that Focus/Do Not Disturb isn’t silencing them.
Does my fast keep counting if I close the app?
Yes. Fastum tracks your fast from the time you started, so closing or backgrounding the app doesn’t lose any time, and your stage reminders still arrive.
Is Fastum medical advice?
No. Fastum is a wellness tool, not medical advice. Please consult a doctor before fasting, especially for longer fasts. See our Terms.
