How it helps
Understand your own progress.
Authorized signals may support personal trends and goal context. They are not a diagnosis and do not replace a qualified professional. Optional AI processing requires the controls and disclosures presented in Matrix.
How it is protected
No ads. No sale of health data.
Matrix does not use Apple Health data for advertising, data brokerage, unrelated marketing, credit, lending, employment, or insurance eligibility.
Revoking access
Permission and deletion are separate.
Revoking a category in Apple Health stops future reads. It does not automatically delete data previously imported into Matrix. Use the Matrix deletion process for stored copies.
Delete stored copies
Your Matrix account has separate controls.
Use Matrix account settings or contact our privacy team to delete information stored by Matrix, subject to the limited lawful exceptions in our Privacy Policy.
