TrustFast Privacy Policy
TrustFast is provided by Ugo Di Profio, a sole proprietor doing business as Atelier Artisanal Digital, in Quebec, Canada ("we").
The short version: your fasting data stays on your iPhone and your Apple Watch. We have no servers that receive it, no account, no advertising, and no tracking. Apple handles subscription payments. RevenueCat receives the purchase information needed to run your subscription. TelemetryDeck receives anonymous signals about onboarding, the Plus page and whether you start and finish a first fast.
Your fasting data
TrustFast keeps your fasts, history, schedule and alert choices on your iPhone. Your paired Apple Watch keeps a copy of what it needs to show and start or end a fast, and the two exchange that information directly with each other through Apple's watch connection. Widgets and Live Activities read it on your iPhone.
We never receive your fasting data. TrustFast has no iCloud sync. Like the rest of your apps' data, it is included in the iPhone backups you make to iCloud or to a computer, under Apple's settings and Apple's privacy policy.
Fasting information appears in widgets, Live Activities and alerts, including on your Lock Screen, where people near your phone can see it.
Alarms and notifications
TrustFast schedules alarms and notifications on your iPhone, using Apple's alarm and notification services, with your permission. They are not sent from a server and work without a network connection.
No account, no advertising, no tracking
There is no TrustFast account or sign-in. The app contains no advertising. TelemetryDeck records only the onboarding, Plus page and first-fast signals described below. TelemetryDeck does not link those signals to your identity or use them to track you across other companies' apps or websites.
If you have chosen in iOS Settings to share analytics with app developers, Apple may give us anonymous crash reports and usage statistics. Apple controls that choice; see Apple's privacy policy.
Subscriptions
TrustFast Plus is an auto-renewing subscription sold through the App Store. Apple processes the payment; we never see your payment details or your Apple Account.
The app uses RevenueCat, a subscription service, to check whether your subscription or trial is active and to restore purchases. To do this, RevenueCat receives your App Store purchase records and an anonymous identifier for your copy of the app. When you open the Plus page, RevenueCat also receives that it was shown, closed, or led to a purchase. We use these records to run subscriptions and to see, in aggregate, how the Plus page performs. None of this is linked to your identity or used to track you, and RevenueCat never receives your fasting data. See RevenueCat's privacy policy.
Your subscription status never affects what is stored. When a trial ends or a subscription is cancelled, no fasting history is deleted.
Anonymous usage signals
The app uses TelemetryDeck to understand how onboarding and the Plus page are used, and whether a first fast was started and later ended. It receives those limited signals and an anonymous identifier for this copy of the app. The identifier is a one-way hash, not your identity. TelemetryDeck does not receive fasting times, durations or history. These signals are not linked to your identity and are not used to track you. See TelemetryDeck's privacy policy.
Deleting your data
Because your data is only on your devices, you control it entirely. Deleting TrustFast from your iPhone and your Apple Watch deletes your fasting data from them; copies in your own backups remain until you delete those backups. We hold no copy to delete. RevenueCat keeps purchase records under its own policy; contact us and we will ask it to delete yours.
Children
TrustFast is not directed at children under 13.
Changes to this policy
If this policy changes, we will post the new version here with a new effective date. If a change affects what leaves your device, we will say so in the app's update notes.
