Privacy Policy
Last updated July 2026
The short version
PeptideMate has no sign-up and no accounts. The calculators run entirely in your browser — the numbers you type in (vial size, dose, water volume, and so on) are used to compute a result on your device and are never sent to us or stored on any server we operate.
What we don't collect
We don't require or ask for your name, email, or any account information. We don't store your calculator inputs or results anywhere — they exist only in your browser tab and disappear when you close it or refresh the page.
Hosting & standard web logs
Like virtually any website, our hosting infrastructure automatically logs standard technical information for every visit — things like IP address, browser type, and request timestamps — for security and reliability purposes. We don't personally access or analyze this data on an individual basis.
Cookies & analytics
We don't currently use cookies, tracking pixels, or third-party analytics. If that changes in the future — for example, adding privacy-respecting analytics to understand which tools are most useful — we'll update this page to reflect it before doing so.
No selling of data
We don't have advertisers, and we don't sell, rent, or share personal data with third parties. There isn't a meaningful amount of personal data collected here to sell in the first place.
Children's privacy
This site is not directed at children, and we don't knowingly collect information from anyone under 18.
Changes to this policy
If our practices change — for instance, if we add accounts, saved calculations, or analytics down the line — we'll update this page and adjust the "last updated" date above.
