# BigBrainParking > Informational site for BigBrainParking, an unofficial, open-source, de-Googled Android client for the ParkSmarter metered-parking system. BigBrainParking is a privacy-focused, MIT-licensed client for the same ParkSmarter parking meters as the official app — without IMEI harvesting, ad/telemetry SDKs, or automatic location pings. It offers a live MapLibre meter map, on-device QR scanning (VisionCamera), paid sessions with local expiry reminders, phone + password login, and optional push via your own UnifiedPush provider. No Google Play Services and reproducible builds; built with GrapheneOS users in mind. Installed via Obtainium straight from source.
