2.2 Personal Profile (stored locally)

If you choose to fill in your profile, the App stores:

2.3 What We Do NOT Collect

•We do not collect your name, email address, or any contact details.

3. How We Use Your Information

All health and profile data you enter is used solely to:

•Allow you to export your history as a PDF file to your device.

This data never leaves your device and is never transmitted to us or any third party by the App itself.
