Privacy Policy
Last updated: March 20, 2026
What we collect
- Account information: If you create an account, we store your email address and display name.
- Email subscriptions: If you subscribe to election reminders, we store your email address and state.
- Ballot lookup addresses: When you look up your ballot, we send your address to determine your jurisdiction. We do not store your address. It is processed in real time and discarded.
- Usage data: We may collect anonymous analytics data (pages visited, time on site) to improve the service.
- Optional geolocation: If you grant browser location permission, we use your approximate position solely to detect your US state and pre-fill state selectors. We never store your coordinates or precise location. Only the derived two-letter state code is saved in your browser’s local storage. You can decline the browser prompt and select your state manually at any time.
