P.S. We may need to update this letter as the product grows. If so, we'll keep it updated right here at heartrate.hedronvision.com/privacy. You've probably noticed that we don't force you to create an account or provide your email—that helps protect your privacy but prevents us from emailing everyone when we make changes. You're always welcome to check back here for updates, and we'll assume you're happy from your continued use of the software.
