Privacy Policy
Effective September 28, 2026
This Privacy Policy explains what information peptideinfo.org (the "Site", "we", "us") collects, how we use it, and the choices you have.
1. What we collect
- Email address and, optionally, first name when you unlock the Peptide Calculator or join our list.
- Calculator inputs (vial size, water volume, dose, syringe and schedule) are stored only in your own browser so the page remembers them. They are not sent to us.
- Technical information that any web server or hosting provider receives when you visit a page, such as IP address, browser type and the pages requested. We may use privacy-respecting, aggregate analytics to understand how the Site is used.
2. How we use it
We use your email address to give you access to the calculator and to send occasional peptide research updates from peptideinfo.org. Every email includes an unsubscribe link, and unsubscribing does not affect your access to the calculator. We do not sell or rent your personal information.
3. Service providers
Email signup and delivery are handled by Kit (kit.com), which stores your email address and name on our behalf under its own privacy policy. The Site is hosted by a third-party hosting provider. Citation links go to PubMed and DOI records, which are operated by third parties.
4. Cookies and browser storage
The Site does not use advertising cookies. The calculator uses your browser's local storage to remember that you have unlocked it and to keep your last inputs. You can clear this at any time through your browser settings.
5. Your choices
You can unsubscribe from emails using the link in any message, which removes you from our mailing list. The calculator inputs the Site keeps live only in your own browser and can be cleared through your browser settings at any time.
6. Children
The Site is intended for adults and healthcare professionals. We do not knowingly collect personal information from anyone under 18.
7. Changes
We may update this Policy from time to time. The effective date at the top shows when it was last revised.
