Privacy policy

Last updated November 3, 2026. Questions: team@stacktracker.co.

This policy explains what Stack Tracker Inc. ("Stack Tracker", "we") collects when you use the app, why, and the choices you have.

What we collect

How we use it

We do not show third-party advertising.

Health information

What you track is sensitive. It is stored encrypted at rest in the United States, protected by access rules so that only your account can read it, and never shared with partners or other users unless you create a share link yourself.

AI assistants

If you connect Claude or ChatGPT, the assistant can read and update your protocols and doses only after you approve the connection with a code from your Account screen. You can disconnect at any time from the same screen.

Keeping and deleting data

We keep your data while your account is open. Email team@stacktracker.co from your account email to export or delete everything; we complete requests within 30 days.

Your rights

Depending on where you live (including the EU, UK and California) you may have the right to access, correct, export, delete or restrict the use of your data, and to object to certain processing. Contact us and we will help.

Service providers

We use trusted providers for hosting, data storage, sign-in, email and payments. Each is bound by its own data-processing terms and handles your data only to run Stack Tracker.

Children

Stack Tracker is for adults. We do not knowingly collect data from anyone under 18.

Changes

We will post changes here and update the date above. Material changes are announced in the app.
