What areAccess tokens?

Access tokens allow exercisync to perform actions on your behalf. By using access tokens, exercisync never needs to store your username or password. In order to obtain an access token, exercisync may need to ask for your credentials - which are erased immediately after being exchanged for an access token.

What isActivity metadata?

Activity Medatada are the basic details of any activity: start time, time zone, duration, distance, and type. exercisync needs to store this information to determine which activities should be synchronized to each of your accounts.

What constitutesActivity data?

Activity data is the complete record of an activity: the GPS track, sensor data, and all metadata. To improve synchronization performance, exercisync temporarily stores (caches) this data from your Dropbox account.

1 I've done a good deal to keep your password safe, but there has to be a way for exercisync to use it to sync your account. Therefore, anyone with enough access and resources to the exercisync database and servers could access it, too.

2 The email address you used to pay is stored so that you can transfer or recover your payment.

All the juicy details

exercisync moves your activities between the services you connect - period. Other than the basic metadata mentioned above, your activity data is not stored on exercisync servers. No activity data or metdata is ever shared with third parties beyond the accounts you connect.

However, the services you connect may, of their own accord, share your activity data with third parties. For instance, at the time I write this, Strava reserves the right to "collect certain use data and information related to [exercisync's] use of the Strava API Materials, and Strava Platform in connection with [exercisync's] Developer Application ("Usage Data"), and that Strava may use such Usage Data for any business purpose, internal or external, including, without limitation, providing enhancements to the Strava API Materials or Strava Platform, providing developer of user support, or otherwise." Please consult the privacy policy for the services you connect in order to determine how they handle your data.

Limited data regarding your interaction with exercisync.com is recorded in order to monitor the performance of the website itself. Google Analytics is used to track website performance, while Sentry records internal server errors.

Exporting & erasing your personal data

Most of the data exercisync stores regarding your accounts and activities is automatically deleted once you disconnect your last service from exercisync.com. Only diagnostic logs regarding your account will remain for a limited period afterwards - but are not stored permanently. During this process, any activities that exercisync synchronized to the services you connected will remain untouched. If you wish to receive a copy of all the data exercisync has stored regarding your user account, or request the deletion of this data, please contact me and mention GDPR in the subject line.
