Privacy Policy — Fastino
Overview
Fastino ("the app") is a free intermittent-fasting tracker for iPhone and Apple Watch. Your privacy is important to us. This policy explains what data the app accesses, where that data lives, and how it is used.
The short version: Fastino has no servers. Nothing you record in it is ever sent to us.
Data We Collect
We do not collect, store, or transmit any personal data. The app has no backend, no analytics, no user accounts, no advertising, and no third-party SDKs. It performs no tracking as defined by Apple's App Tracking Transparency, and it contacts no network service of ours — because there isn't one.
Apple Health
With your permission, Fastino reads two kinds of data from Apple Health so it can show them alongside your fasting history:
- Sleep — to show how much you slept on a given night
- Body mass (weight) — to show your weight trend week by week
How that data is handled:
- It is read only when a screen needs it and held in memory only. It is never written to the app's database, never cached on disk, and never included in iCloud sync.
- It is never transmitted anywhere — not to us, not to any third party.
- It is never used for advertising, marketing, or data mining, and is never sold or shared with anyone.
- Fastino never writes anything to Apple Health. It requests read access only.
Granting Health access is optional. Fastino works fully without it; the sleep and weight panels simply stay empty. You can review or revoke access at any time in the Health app, under Sharing → Apps → Fastino.
iCloud Sync
If you are signed in to iCloud, your fasts and settings sync between your own devices through your own iCloud private database. This is Apple's CloudKit private storage: the data belongs to your Apple Account, and Baleware has no access to it and cannot read it. We operate no server that touches it.
Apple Health data is excluded from this sync entirely, as described above.
You can turn sync off in iOS Settings → your name → iCloud, by disabling iCloud Drive access for Fastino. Fastino keeps working as a local, single-device app.
Data Stored on Your Device
The app stores the following locally:
- Your fasts — start time, end time, goal, and any notes you add
- Your settings — fasting protocol, reminder times, appearance
- A small technical log of iCloud sync activity, used for the in-app sync diagnostics. This records only event types and timestamps — never the contents of your fasts.
- Which of your devices is responsible for scheduling notifications
This data is not accessible to other apps, and is deleted when you delete the app. Deleting the app does not remove the copy in your own iCloud account; you can remove that in iOS Settings → your name → iCloud → Manage Account Storage.
Apple Watch
If you use the Apple Watch app, the watch and the iPhone exchange a single technical signal so that only one of them schedules your notifications and you don't get every alert twice. No fasting data is sent over this channel, and the signal is not stored on either device. Your fasts reach the watch through your own iCloud account, as described above.
Notifications
Reminders and goal alerts are scheduled locally on your device. There is no push server, so no notification is ever composed or delivered by us. Permission is requested only when it would first be useful, never on launch, and Fastino works without it.
In-App Purchases and Advertising
There are none. Fastino is free, contains no advertising, and has no in-app purchases or subscriptions.
Children's Privacy
The app does not knowingly collect any data from children — it collects no data from anyone. It contains no tracking, advertising, or social features.
Changes to This Policy
If we update this policy, the revised version will be posted at this page with an updated date.
