Privacy Policy

Last updated: September 11, 2026

Nestis ("the app," "we," "us") is a fasting timer and tracker for iPhone. This policy explains what data the app collects, how it's used, and your choices.

What we collect

• Your fasting sessions, journal entries, and preferences. Start and end times, schedule goals, journal notes, and app settings (like your chosen theme and accent color) are stored on your device and, if you're signed into iCloud, backed up privately using Apple's iCloud/CloudKit. We do not have access to this data; it is stored in your personal iCloud account, encrypted and managed by Apple.
• Purchase information. If you subscribe to Nestis Pro, purchase and subscription status is processed by Apple and our payments provider, RevenueCat, to verify your entitlement. This includes an anonymous purchaser ID and transaction data; it does not include your payment card details, which Apple never shares with us.
• Notifications. If you enable milestone or reminder notifications, the times you choose are stored on your device to schedule local notifications. These are scheduled entirely on-device, and we don't see when or whether you receive them.

What we don't do

• We don't sell your data to anyone.
• We don't run third-party advertising or ad-tracking SDKs.
• We don't use analytics tools that build an advertising profile of you.

Third parties

We use two services to operate the app:

• Apple (iCloud/CloudKit): stores and backs up your fasting data privately in your own iCloud account. See Apple's Privacy Policy.
• RevenueCat: manages subscription status for Nestis Pro. See RevenueCat's Privacy Policy.

Your choices

You can export your data at any time from Settings, and delete all of your data by deleting the app and, if you wish, removing Nestis's data from Settings → [your name] → iCloud → Manage Storage on your device. Uninstalling the app does not cancel an active subscription; subscriptions are managed and cancelled through Settings → [your name] → Subscriptions on iOS, or via the "Manage Subscription" link inside the app.

Children's privacy

Nestis is not directed at children under 13, and we do not knowingly collect personal information from children.

Changes to this policy

If this policy changes, the "Last updated" date above will change. Continued use of the app after an update means you accept the revised policy.
