Privacy Policy — Hollow Watch Face
Last updated: October 17, 2026
Hollow is a Wear OS watch face built entirely with Android's
Watch Face Format —
a declarative XML format with no application code. There is nothing in this app that
could collect, store, or transmit data even if it wanted to.
What this app does
- Displays the current time (HH:MM) on four stone pillars, read from the watch's own
clock.
- Displays a moon-phase icon, computed on-device from the operating system's own
built-in moon-phase data source — no network request, no location, no permission.
- Optionally displays weather and date complications — standard Wear OS
widgets. The data for these comes from whatever complication provider you choose in the
watch face editor (e.g. your phone's own weather app); this watch face only asks the
operating system to render whatever that provider supplies. It never receives, stores, or
forwards that data itself.
What this app does not do
- It requests no Android permissions — check the app's own
AndroidManifest.xml in the
public source repository.
- It has no network access, no analytics, no advertising, no accounts, and no
in-app purchases.
- It does not collect, store, transmit, or share any personal data, on the device
or off it.
Source
This app is open source (Apache-2.0) — the entire watch face is generated from one
Python script, and the generated watchface.xml is the entire app. See
github.com/pburney/HollowWatchFace.
