Blobby

Privacy policy

Last updated 9 October 2026 · applies to the Blobby app, test version 1.3

Blobby is a training game for your body: short drills for balance, reaction, hand-eye and your weaker hand. Your results stay on your phone, and we only learn from you when you say yes.

This test version of the policy covers Blobby during its test with invited players. We will update it before Blobby is in the stores for everyone, and tell you in the app if anything important changes.
