Fasta is built around a simple promise: your data stays on your device.

What We Collect

Fasta does not require an account, does not run ads, and does not use third-party advertising analytics. Your core fasting data is stored locally on your device. We do not operate a Fasta account server that receives your fasts, weight, water intake, measurements, mood, energy, readiness history, voice journals, or progress photos.

What Is Stored Locally

Your name, fasting plans, fasting history, water entries, weight entries, body measurements, mood and energy check-ins, readiness history, recap preferences, voice journal text, progress photo references, settings, subscription app user ID, and achievement unlocks are stored in a local database inside the app's private sandbox on iOS or Android.

Data Retention and Deletion

Fasta retains data stored in its private app sandbox for as long as you keep the app installed and do not delete that data. You can delete individual records where the app provides a delete action, or use Fasta's Delete local data action to remove your local profile, goals, logs, history, check-ins, recaps, schedules, and reminder details. Uninstalling Fasta removes its app-private local data from iOS or Android. Fasta does not retain a copy on a Fasta account server.

Data already stored in Apple Health or Health Connect is retained by those platform services until you delete it there; deleting Fasta does not delete those records. Files you export are retained by the destination or people you choose to share them with. RevenueCat retains the pseudonymous app user ID and purchase entitlement information it receives according to its own privacy policy and as needed to provide subscription services.

Apple Health and Health Connect

If you grant permission, Fasta can read selected health data from Apple Health on iOS or Health Connect on Android, including weight, hydration, sleep, HRV, resting heart rate, steps, active energy, and blood glucose where supported. Fasta can write weight and water entries you choose to log. This data flows directly between Fasta and the platform health service on your device. Fasta does not use health data for advertising, sell it, or send it to a Fasta account server. Readiness and coach suggestions are wellness guidance only, not medical advice.

Notifications

Fasta uses local notifications for fasting milestones, fast completion, and optional reminders. You can disable notifications in your device settings or inside Fasta.

Voice Journals

If you choose to use voice journaling, Fasta asks for microphone and speech recognition permission. Voice journaling is optional. Audio is used to create a private journal transcription on your device and is not sent to a Fasta server.

Photos and Camera

If you attach a progress photo, Fasta asks for camera or photo library permission. Photos stay on your device and are only used for the progress entry you choose to create.

Partner Fasting and Local Network

If you use partner fasting, Fasta may ask for local network permission so nearby devices can connect directly. This feature is designed for peer-to-peer use without Fasta accounts or a Fasta server.

Purchases and Premium

Fasta Premium subscriptions are purchased through Apple on iOS or Google Play on Android. Fasta uses RevenueCat to check available products, purchases, restores, and Premium entitlement status. RevenueCat receives a pseudonymous app user ID and purchase entitlement information for subscription management. This is not used for advertising tracking.

Data Export

You can export data, reports, backups, or recap images through your device's sharing tools. Where you send those files is your choice. Fasta does not receive a copy.

Third-Party Services

Fasta uses Apple services for App Store purchases and Apple Health on iOS, Google Play and Health Connect on Android, device notifications, speech recognition, camera/photo permissions, and local networking. Fasta uses RevenueCat for subscription product and entitlement management. Fasta does not use third-party advertising trackers.
