Privacy
Updated 26 August 2026. This policy describes what this site stores on your device.
Who operates this site
KnownPeptides is the educational site at knowspeptides.com. You can create an optional account to sign in. Shop checkout is not offered on this site right now.
What stays on your device
Favorites, recently viewed peptides, the shop cart, and the light/dark appearance preference are stored in this browser (local storage). They are not sent to KnownPeptides. Clearing site data in the browser removes them. The settings page explains that saved list data lives on the device.
Account and usage log
If you sign in, KnownPeptides stores your account email with the auth provider and any personal usage log entries you save (peptide, amounts you type, dates, notes, vial counts). That log is private to your account. It is not medical advice. Optional reminder emails only go out if you turn them on for a protocol. Favorites, recently viewed peptides, the shop cart, and appearance still stay in this browser until you clear them.
What this site does not collect
KnownPeptides does not run a payment form, newsletter signup, or advertising pixel. It does not sell personal information. Server logs from hosting may include IP address, user agent, and the URL requested.
Cookies
Appearance uses local storage, not an advertising cookie. Signed-in sessions use cookies required to keep you signed in. There are no third-party ad cookies on this site.
Your choices
Device-local tools run because you use the site. You can clear them in the browser. For questions about this policy, use the contact page.
Children
This site is not directed at children. Research-vial orders are not offered to minors.
