Numo Fast privacy policy
Last updated: 14 November 2026
Numo Fast is an intermittent fasting timer for Android, developed and published by Novixway LLC ("Novixway", "we", "us"). This policy explains what Numo Fast does with information on your phone.
The short version: Numo Fast has no accounts, no ads, no analytics and no crash reporting. Your fasts, plans and logs are stored on your phone. Numo Fast does not send them, or anything else, to Novixway or to anyone else.
Data kept on your phone
| Data | Why | Leaves the phone? |
|---|---|---|
| Fasts: start time, end time, goal length and plan | to run the timer and show your history, streaks and stats | No |
| Custom plans and your weekly schedule (Pro) | to pick the plan for each day | No |
| Weight entries and water entries you type in (Pro) | to show your log and charts | No |
| Settings, such as theme, units, water goal and notification choices | to keep the app the way you set it | No |
| Whether Pro is unlocked | so Pro works offline | No |
All of this is stored in Numo Fast's private app storage, which other apps cannot read. You can edit or delete any fast or log entry in the app at any time. Uninstalling Numo Fast, or clearing its storage in Android Settings, deletes all of it.
Numo Fast does not read Health Connect, Google Fit or any other health service, and it does not use your location, contacts, camera or microphone.
Android backup. If you have turned on Android backup for your device, Android may include Numo Fast's data in your device backup, which Google stores in your Google account under your backup settings. Novixway has no access to your backups. You can turn backup off in Android Settings.
Export and backup files (Pro)
When you export a CSV file or create a backup, Android's file picker opens and you choose where the file goes. Numo Fast writes the file only there. When you restore, Numo Fast reads only the file you pick. Where the file goes next, for example a cloud drive you chose, is governed by that service's own policy.
Notifications and alarms
Numo Fast can show a notification while you fast and another when you reach your goal. To do this it schedules alarms on your phone and sets them again after a restart. Nothing about this is sent anywhere.
Purchases
Numo Fast Pro is a one-time purchase handled by Google Play. Google processes the payment under the Google Privacy Policy. Numo Fast asks Google Play on your device whether Pro was bought, so it can unlock it. Novixway does not receive your payment details.
Network
Numo Fast works offline. The only network activity related to it is Google Play's own: checking the Pro purchase and price, and installing and updating the app.
What we do not do
- No account or sign in.
- No ads and no advertising ID.
- No analytics, tracking or crash reporting SDKs, and no Firebase.
- No sale or transfer of your information to anyone.
Not medical advice
Numo Fast measures time. It is not a medical device and does not give medical advice. Talk to a doctor before fasting if you are pregnant or breastfeeding, have diabetes, take medication, or have a history of eating disorders.
Children
Numo Fast is not directed at children under 13, and fasting apps are not meant for children.
Changes
If this policy changes, the new version will be posted at this address with a new "Last updated" date. Material changes will also be noted in the app's release notes.
