Last updated: May 20, 2026
Hair Thinning Check ("we," "our," or "the site") respects your privacy. This policy explains what information we collect, how we use it, and your rights.
Photos You Upload
Photos you upload for analysis are not stored on our servers. They are processed in your browser and sent directly to our AI vision provider (Anthropic) solely to generate your Ludwig scale result. We do not save, log, or share these photos. Once you close the page, the photos are gone.

We do not collect names, email addresses, or other personal identifiers unless you voluntarily provide them.
