# PediTools app: privacy policy

Last updated: 2026-10-27

- **Patient data:** nothing entered in the app is saved, analyzed or sent anywhere. Entries are kept only while the app is open, and a patient file or bulk file only while its screen is open.
- **Preferences:** the app remembers, on this device only, how you like it to work: the look, the WHO SD23 setting, the recently used charts, whether the dates section is open, the patient growth chart's plot options and the bulk page's download options.
- **Saved files:** "Save the patient file", "Download the table" and "Download the results" open your device's share sheet. The file goes only where you choose (files, email, another app), and the app keeps no copy.
- **Correction notice:** when online, at most once a day, the app reads a small file on PediTools that lists known corrections. Nothing is sent with that request, though like any web request it reaches the server from your device's internet address.
- The app has no ads, analytics, accounts or tracking.
