Tangey uses Oauth2 with Strava as a provider. All communications between Tangey and Strava servers always happens over HTTPs, and no data ever leaves your device.
Tangey's website uses the open source Plausible Analytics to count website visits so the developer can be happy when someone new discovers the app. No cookies are used and no personal data—not even an IP address or browser user agent—is stored. For more information, see the Plausible Data Policy.
