blocks.zone · last updated 18 June 2026
Blocks is a structured-workout builder for cyclists and runners at blocks.zone. This page explains what we store and why.
What we store
If you sign in with Google, we store your name, email and profile image (for authentication), and the data you create in the app: your workouts, training profile (FTP, pace, zones) and favorites. Browsing the catalog and collections works without signing in and stores nothing.
Connected services
If you connect a third-party service such as intervals.icu, we store the access token it issues so we can send workouts you choose to your account there. The token is encrypted at rest and is only used on the server to perform actions you initiate. It is never shown to your browser or shared with anyone. You can disconnect at any time on the Connections page, which deletes the stored token. We only request the minimum scope needed (calendar write).
What we avoid
We do not sell your data, run third-party advertising or analytics trackers, or access connected accounts beyond the actions you trigger.
Data removal
To delete your account and all associated data, or for any privacy question, email gavrilov4444@gmail.com.
