// Download
CELAJE is distributed only here, not through app stores. To install, open the downloaded file and allow your browser to install apps when Android asks (a one-time setting). Updates install over the previous version and keep your widgets and places.
For automatic updates use Obtainium:
add this page’s address as an HTML source and it will pick up new celaje-x.y.apk links as they appear. Machine-readable version info:
latest.json.
Verify the download: sha256sum celaje-1.1.1.apk must print the hash above. All releases are signed with the same key, so Android will refuse an APK that was not built by us.
// What you get
// Privacy
No account, no analytics, no advertising SDK. The only permission is Internet (plus opening your clock app when you tap the time). The app talks to Open-Meteo for forecasts and place search; everything astronomical and the default tide model are computed on the device.
// Questions
Why isn’t CELAJE on Google Play?
We distribute it only from this site: free, no store account, no tracking SDKs, and updates the moment they are ready. Android warns once about installing from a browser — that is expected.
Does the app track my location?
No. It has no location permission at all. You type or pick a place; only that place’s coordinates go to Open-Meteo to fetch the forecast.
How do tides work without an internet connection?
The default tide model runs on the device from bundled EOT20 harmonic constituents. Only the weather forecast needs the network.
How do I get updates?
Download the new APK from this page — it installs over the old one and keeps your widgets and places — or add this page to Obtainium as an HTML source for automatic updates.
Which Android versions are supported?
Android 10 and newer, with any launcher that supports resizable widgets.
