Privacy policy

Last updated July 6, 2026

Precinct collects no data. It has no accounts and no analytics, and it never talks to a server. Every precinct boundary, election result, and Census figure it shows ships inside the app.

Your location

Precinct asks for your location for one reason: to look up the precinct you’re standing in. The lookup runs entirely on your device against the app’s built-in database. Your coordinates stay in memory just long enough to find the precinct, then they’re gone. Nothing is written to disk or sent off the device. The home and lock screen widgets work the same way.

Location access is optional. If you decline, you can still explore every precinct by tapping the map or searching.

Third parties

The app contains no third-party code or SDKs, so there is no one to share anything with.

The data shown in the app

The maps and numbers in the app are public records: precinct boundaries from the Census Bureau and state election offices, joined to presidential returns, the 2020 Census, and the American Community Survey. None of it is about you.

Changes and contact

If this policy ever changes, the new version will be posted here with a new date. Questions can go to precinct@ethangao.xyz.
