App: Meteo: Barometer & Weather Map
Package: com.digitalrhyme.meteo
Effective date: 2026-11-14

    Short version: Meteo has no account, no ads, no analytics and no tracking.
    Your pressure readings, history and height stay on your phone. The only network use is the
    optional pressure map, which downloads public weather data for a rounded area (about 100 km),
    never your position.

1. Who we are

Meteo is an independent app developed by Digital Rhyme. Contact: sazran@gmail.com.

2. Data we do not collect

No user accounts or registration
No analytics, usage tracking or crash reporting to any server
No advertising, no advertising identifiers
No device identifiers, contacts, photos, files or payment information

3. Pressure readings and history

Meteo reads your phone's barometer. Readings, the recorded pressure history (kept 90 days) and your settings are stored only in the app's private storage on your phone. They are never uploaded. Uninstalling the app deletes them.

Background recording is off until you turn it on. While it is on, Android shows a permanent notification and Meteo takes a short reading about every 15 minutes. Turn it off in the app or with "Stop recording" in the notification.

4. Location

Location is used for two optional features, only after you ask for them:

Height for sea-level pressure (precise location, GPS): when you tap Measure, Meteo averages GPS fixes for up to 3 minutes to find your height above sea level. Between measurements the barometer follows your height; if a GPS height has become uncertain (after a long gap, a big move or 3 days), Meteo measures again by itself, only while the app is open on screen. Only the height and its accuracy are saved, on the phone. Coordinates are not stored or sent.
Pressure map (approximate location): when you open the map, Meteo needs to know which region to show. Your location is rounded to whole degrees (about 100 km) before anything is sent; see section 5. The model value at your exact position is computed on the phone. If you pan the map to another area, that area's centre, also rounded to whole degrees, is used the same way.

Location is never used in the background. You can deny the permission; the rest of the app keeps working, and you can enter your height by hand.

5. Internet — the optional pressure map

Everything in Meteo works offline except the pressure map. Only while the map screen is open, the app contacts these public services:

Open-Meteo — forecast-model pressure for a grid of points around the rounded map centre.
aviationweather.gov (US National Weather Service) — public airport weather reports (METAR) in the same area.
OpenFreeMap — base-map tiles for the area shown on screen (like any web map).

These requests contain no personal data, only the area. Like any internet request, the services can see your IP address; their own privacy policies apply. Downloaded map data is cached on the phone for 30 minutes. Your own readings are never sent.

6. Third-party libraries

Meteo uses AndroidX/Jetpack (Google, Apache 2.0) and MapLibre (BSD, map rendering). Neither collects data for us; MapLibre only downloads the map tiles described above. There are no advertising, analytics or crash-reporting SDKs.

7. Children

Meteo collects no personal information from anyone, including children.

8. Changes

If the way Meteo handles data changes, this page and its effective date will be updated, and the change noted in the Play Store release notes.
