BP Tracker – Privacy Policy
Last updated: November 14, 2026
Who this covers
BP Tracker is a personal tool used only by its owner, Adam Sherlip. It does not collect data from anyone else.
What data it accesses
With the owner's explicit permission through Google's consent screen, BP Tracker reads the owner's own Google Health data: body measurements (such as weight), sleep sessions (such as duration and sleep stages), and activity and fitness data. Access is read-only. BP Tracker does not change or delete anything in Google Health.
How the data is used
Only to display the owner's weight and sleep alongside his blood-pressure readings in his private tracker. It is not used for advertising, profiling, or any other purpose.
Where it is stored
Google sign-in tokens are stored only on the owner's personal computer. Imported values (dates, weight, hours slept, sleep stages) are stored in the owner's private tracker, which is hosted with Anthropic (Claude) and visible only to the owner.
Sharing
Data is never sold or shared with anyone. It is processed only by the services needed to run the tracker: Google, as the data source, and Anthropic, as the host of the tracker.
Google API Services
BP Tracker's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Retention and deletion
Data is kept for as long as the owner uses the tracker. Access can be revoked at any time at myaccount.google.com/permissions, and imported data can be deleted from the tracker at any time.
