Frequently Asked Questions
What fasting plans are available for free?
The free plan includes 14:10, 16:8, 18:6, and 20:4 fasting schedules with a real-time countdown, progress ring, daily water tracking, weight logging with BMI, streak tracking, journal entries, smart alarms, CSV export, and theme options. You get a full fasting toolkit at no cost.
What does the premium subscription include?
Premium unlocks Custom & OMAD fasting plans, the ability to adjust start time (backdate a fast), extend fast duration mid-fast, advanced analytics with weight projections, PDF export, an ad-free experience, and priority feature updates. It costs $2.99/month or $17.99/year (saving 50%).
How does the 7-day free trial work?
When you subscribe to any premium plan, you get 7 days of full premium access at no charge. If you cancel before the trial ends, you will not be billed. Your subscription is managed through Google Play, and you can cancel anytime from your Google Play account settings.
How do I cancel my subscription?
Open the Google Play Store app, tap your profile icon, then go to Payments & subscriptions > Subscriptions. Find Fasting Diary and tap Cancel subscription. You will keep premium access until the end of your current billing period. Uninstalling the app does not cancel your subscription.
Is my data stored on your servers?
No. All your fasting logs, weight entries, and journal notes are stored locally on your device. We do not transmit your personal health data to any server. For full details, see our
Privacy Policy.
I lost my data after reinstalling. Can I recover it?
Because data is stored locally on your device, uninstalling the app removes all fasting history and settings. We recommend using the Export Data (CSV) feature in Settings before uninstalling. If you have already lost data, unfortunately it cannot be recovered.
