Bill search results and stage/sitting dates come live from the free, publicly available UK Parliament Bills API (bills-api.parliament.uk) whenever this app calls out to refresh them - an internet connection is needed for search and for "Refresh stages". Everything else - which bills you're tracking, and any notes or links you attach to a stage - stays only in this app, stored locally on this device, and is never sent anywhere. This is a personal research tool, not a legislative or legal record: always check bills.parliament.uk directly for the authoritative, up-to-the-minute status of any bill before relying on it.
