FAQ
Clear answers.
Why no accounts?
Because fasting doesn't need identity infrastructure. You open the app and start. That's it.
Where is my data stored?
On your device only. Timer state, history, and settings are local-first and offline.
Will you add AI coaching?
No. ClearFast is intentionally anti-bloat and keeps the product focused on core utility.
Can I export my history?
Yes. Premium includes styled PDF export with custom filename support. Free users can still view, delete, and manage history inside the app.
Are there ads in the free version?
No. ClearFast is ad-free in both Free and Premium. Premium adds Custom plans, unlimited history, PDF export, and deeper personalization — not ad removal.
