Privacy Policy — Wear OS apps

Effective: 6 September 2026

This policy covers the Tumbatu Collection watch faces (Jua, Upeo, Pwani, Mwangaza, Ngalawa, Wavu, Machweo, Urembo) and the CRZA Solunar Engine complication, published on Google Play by CRZA Visual Labs (developer name "CRZAnthony").

The short version

These apps do not collect, store, transmit, sell or share any personal data. There are no accounts, no analytics, no advertising SDKs and no network access.

Watch faces (Tumbatu Collection)

The watch faces are built in Google's Watch Face Format. They contain no executable code. They display information the watch already holds — time, date, weather, heart rate, step count, battery level, sunrise and sunset — by reading it from Wear OS on the device. Nothing is written anywhere, and nothing leaves the watch.

CRZA Solunar Engine (complication)

The Solunar Engine computes lunar feeding windows on the watch itself.

Location. The app may ask for coarse (approximate) location. This is optional. If granted, the location is used once per calculation, on the device, to refine moonrise and moonset times. It is not stored beyond the current calculation, is not logged, and is never transmitted. If you decline, the engine uses your watch's time zone instead and still works.

Nothing else. The app has no internet permission and cannot send data anywhere.

Children

These apps are not directed at children under 13 and collect no data from anyone.

Changes

If this policy changes, the new version will be posted at the same URL with an updated effective date.
