Privacy Policy: Peptide Calculator Chrome extension

Published by Prism Labs. Effective October 27, 2026.

This policy covers the Peptide Calculator extension for Google Chrome (item ID aeodgnglneggbkahjhdicdpogcffppie). The extension calculates peptide reconstitution concentration and units on a U-100 syringe.

Data we collect

None. The extension does not collect, transmit, sell or share any personal or sensitive user data. It has no account, no analytics, no advertising and no tracking.

Data stored on your device

The extension saves the last numbers you entered (vial size, water volume, amount and unit, syringe size, and whether the chart is open) in the browser's local storage, so they are still there the next time you open it. This data stays on your device. It is never sent to Prism Labs or anyone else. Removing the extension deletes it.

Permissions and network access

The extension requests no browser permissions and no host permissions. It has no background script and no content scripts, does not read the pages you visit, and makes no network requests. All of its code is included in the package.

Links to our website

The popup has links to guides and product pages on prismlabs.store. A link opens only when you click it, in a new tab. The links carry campaign tags (utm_source=chrome_extension) so the site can count visits that came from the extension. Once you are on prismlabs.store, the Prism Labs website privacy policy applies.

Children

The extension is not directed at children under 13 and collects no information from anyone.

Changes

If this policy changes, we will update this page and its effective date.
