At zustrack, your privacy is our priority. As a Local-First application, we handle your data differently than traditional web apps.
All your route data, GPX files, and settings are stored locally in your browser using PGLite (WASM Postgres) and IndexedDB. We do not have a central database where your tracks are stored.
Your sensitive activity data never leaves your device to be stored on our servers. Any analysis (weather, terrain) is performed by sending coordinates to public APIs, but your original tracks are not kept by us.
We use third-party providers (Google, Strava, etc.) only to identify you and allow access to the application. We do not sell or share your profile data with anyone.
zustrack is open source. You can audit our code to verify how your data is handled.
