FitFixer is a free tool for fixing GPS glitches in FIT files. This page explains what data is processed and how.
Uploaded FIT files are stored temporarily (max 24 h) and automatically deleted. FitFixer does not share your file or its contents with any third party. No account or personal data is required to use the tool.
If you choose to upload to Strava, FitFixer requests only the activity:write scope — the minimum required to upload a file on your behalf. FitFixer does not read your Strava data. The access token is used once for the upload and is not stored.
You can revoke FitFixer's access at any time in Strava → Settings → My Apps.
