4. Data Sharing

We do not sell or share your personal information

AceSense does not sell personal information for money or other valuable consideration. We also do not "share" personal information for cross-context behavioural advertising (as those terms are defined under the CCPA/CPRA). We honour Global Privacy Control (GPC) signals from browsers that send them. There is nothing to opt out of because no sale or sharing is occurring — if that ever changes, we will update this policy and provide an opt-out mechanism before any such sharing begins. To confirm your status or exercise any privacy right, email privacy@acesense.io.
