Privacy policy

Effective 6 November 2026. BaroLog is published by Eastframe Technology LLC.

What we collect: nothing. BaroLog has no account system, no analytics, no advertising, and no crash reporting service. It sends no data to us.

Pressure readings and headache notes are stored in a local database on your device until you delete them or uninstall the app. If you export them as CSV, the file goes to the app or service you choose in the share sheet.

Location and the forecast. To show the forecast and calibrate sea-level pressure, the app asks for your approximate location "while using the app". It rounds the position to about 10 km and sends only that rounded position to MET Norway, the Norwegian Meteorological Institute, to fetch the pressure forecast. No identifier, account or other data is sent with it. The rounded position is stored on your device so the forecast can refresh in the background. You can use BaroLog without location; the barometer still works.

Forecast credit. Forecast data from MET Norway, licensed under CC BY 4.0. Versions before 1.0.1 used Open-Meteo instead.

Notifications for pressure drops are created on your device. Nothing is sent to a server to deliver them.

Purchases are handled by the App Store or Google Play. We do not see your payment details. On Android, the app includes Google Play's billing library, which has the internet permission and connects to Google Play to handle purchases. Google's privacy policy applies to that connection.

Third parties. The app contains no third-party advertising or analytics code. Apart from the forecast request described above, the only external links are this page and the store's own pages, opened at your request.

Children. BaroLog is not directed at children and collects no personal information from anyone.

Changes. A new version of this policy will be published at this address with a new effective date.
