Why no account?

Saved fits

OpenBikeFit works without one — on purpose.

Your fits stay on your device — that's a feature

  • Full privacy by design. Measurements, symptoms and analyses never leave this device. There's no login to phish, no database of your body data to breach, nothing to sell.
  • Everything still saves. Your fits live under Your saved fits and survive closing the browser.
  • Need a durable copy? Every report can be printed or saved as a PDF, and the raw data exports as JSON — from the report page.
Want cloud backup anyway?
If opening your fits on another phone or computer matters to you, press the Help button in the corner and tell us. If riders ask, we'll ship it — free and strictly opt-in, with local-only staying the default.
