Who runs this service?
sliepie Training Sync is an independent service run by sliepie (Jarno Nijboer, Netherlands). He is responsible for your data. Contact: inquiries@sliepie.dev.
What data do we use?
We use your account details, your planned trainings, the results of your runs, such as distance, pace, heart rate and your own rating of the run, and your feedback. We also record your consent and the status of your connections. We receive this data from you, from Run2Forty2 and, if you connect Garmin, from Garmin.
Why do we use this data?
We show your Run2Forty2 trainings and let you enter or edit feedback, also without Garmin. We put your planned runs on Garmin. We fill in your feedback with the results of matching runs. When you send that feedback, it goes to Run2Forty2. Your coach can view that feedback there.
These connections and transfers rely on your consent (GDPR Article 6(1)(a)), including explicit consent for health data (Article 9(2)(a)). Sign-in and security rely on our legitimate interest in providing a secure service (Article 6(1)(f)).
Who receives your data?
We share your training data only with Run2Forty2 and Garmin for these transfers. They process it under their own privacy notices: Run2Forty2 and Garmin.
Providers that host and operate the service act only on our instructions under a processing agreement. We do not sell your data or use it for advertising or AI.
Your data may be processed outside the European Economic Area. This only happens under an EU adequacy decision, under the EU standard contractual clauses (published by the European Commission), or because the transfer is needed to provide the service you asked for, such as sending your trainings to Garmin.
How long do we keep it?
We process only the data the service needs, and keep it no longer than needed. We keep activity results and feedback until they are sent to Run2Forty2, or until it is clear they cannot be sent. We keep unsent results and the remaining data until your account is removed.
Your choices and rights
You have the right to access, rectify and erase your data, to restrict its use, and to data portability. You can object at any time, on grounds relating to your situation, to our use of your data for sign-in and security. You can withdraw consent at any time. This does not affect the use of your data before withdrawal. Remove your data from the Account page.
Connecting Garmin is optional. Disconnecting Garmin stops new transfers with Garmin; remove your account to erase earlier data too.
Manage data already sent to Run2Forty2 or Garmin with those services. You can complain to the Dutch Autoriteit Persoonsgegevens.
