Privacy policy
Pesyra works without an account, advertising profile, developer backend or tracking.
No registration, login, name or personal profile.
No ads, tracking or third-party analytics SDKs.
Your weight and measurements stay on your iPhone.
Pesyra does not collect or transmit your weight or body measurements to the developer. Records and preferences are processed locally to provide the features you choose. Data leaves the app only when you explicitly export a file or open an external link.
Last updated: 31 August 2026.
This policy describes processing performed by Pesyra 1.0 for iPhone. It does not cover processing independently performed by Apple or by a website or storage destination you choose to use under its own terms.

Pesyra may store information that you enter or configure inside its local app container:
Pesyra does not request your name, email address, account, age, date of birth, location, contacts, photos or Apple Health data. The body reference is optional, is not an identity profile and does not restrict features.
Pesyra has no user account, product server or developer backend. It includes no ads, tracking, IDFA use, third-party analytics or third-party crash-reporting SDK. It does not synchronise through CloudKit or access HealthKit. Its privacy manifest declares no tracking and no data collected by the developer.
Pesyra is bought once through the App Store. The app contains no subscription, advertising, trial, paywall or additional in-app purchase. Apple processes the purchase, download and any refund according to Apple’s own terms. The developer does not receive your measurement history as part of that transaction.
Pesyra can schedule an optional measurement reminder locally through iOS. Notification permission is requested only after you choose a reminder, and the rest of the app continues to work if you decline. The app does not use a push-notification server.
iOS provides app-container protection and may include the app’s local container in a device backup according to your Apple settings and Apple’s policies. The developer cannot inspect or retrieve that backup.
You can export a complete JSON backup or a readable CSV file. A file leaves Pesyra only after you choose a destination using the system interface. From then on, it is controlled by you and by the selected destination’s privacy terms; Pesyra cannot delete copies stored elsewhere. Importing reads a file you select, previews it and applies it locally only after your confirmation.
The Learn area offers optional links to sources from organisations such as WHO, CDC and NCBI. Opening a link causes an ordinary web request to the destination, which may receive information such as your IP address under its own policy. Pesyra does not add your measurements, history or an advertising identifier to the link.
Local information remains until you edit or delete it. You can correct individual days, disable a metric without deleting its history, export a backup, import a compatible backup, or choose Erase all data. Complete deletion removes measurements, history, preferences and Pesyra-managed reminders from the app on this iPhone and returns to setup.
Because Pesyra has no account or backend, the developer cannot view, recover or remotely delete local records. Keep a JSON backup before deleting the app or changing devices if you want to preserve your history. Files previously exported elsewhere must be deleted from those destinations by you.
The only user permission expected in version 1.0 is notifications, and it is optional. Pesyra does not request camera, photos, microphone, location, contacts or Health access. You are responsible for securing access to your unlocked iPhone and exported files.
Weight and body measurements can be sensitive. Pesyra is a private record-keeping and educational tool, not a medical device, diagnosis, treatment, personalised recommendation or emergency service. Its trends and body-fat values do not establish a clinical conclusion. The app is not designed to collect personal data from children, and the developer receives no age or account information.
If Pesyra’s data practices change, this page and its date will be updated before a version relying on that change is released. Any future feature that collects or transmits data would require a new review and a clear explanation.
The Pesyra support page explains measurements, reminders, backups and deletion. Pesyra cannot inspect your local records remotely.
