1. Who operates this website
PeptideCalc is an independent browser-based calculation tool available at www.peptide-calculator.uk. Privacy questions can be sent to dev@evetrend.com.
2. Calculator inputs and saved results
Reconstitution and blend calculations run locally in your browser. Values entered into calculator fields are not intentionally transmitted to our server or Google Analytics. If you select “Save result locally,” the saved record is stored in your browser using localStorage. It remains on that device until you delete it, clear saved results, or clear browser data.
3. Optional Google Analytics
With your consent, we use Google Analytics to understand general website usage, such as page visits, device type, approximate region, referrer, and interaction statistics. Google may process IP addresses and online identifiers. We configure analytics only after you choose “Accept analytics” in the privacy banner.
Google’s handling of information is described in Google’s Privacy Policy and its partner sites information.
4. Cookies and consent
Optional analytics cookies are denied by default. Your cookie choice is stored locally so the banner does not need to appear on every visit. Rejecting optional cookies does not prevent use of the calculators. You may change your choice by clearing this website’s local storage and revisiting the site.
5. Advertising and third-party vendors
If Google AdSense advertising is enabled, third-party vendors, including Google, may use cookies, web beacons, IP addresses, or similar identifiers to serve, measure, and personalize ads. Google’s advertising cookies may allow Google and its partners to serve ads based on visits to this website and other websites.
Users can manage or opt out of personalized advertising through Google Ads Settings. Additional industry opt-out choices may be available through AboutAds.
6. Health-related and sensitive information
Do not enter names, email addresses, medical record numbers, or other personally identifiable information into calculator fields. PeptideCalc does not use calculator values to create advertising audiences, infer medical conditions, or personalize advertising based on health information.
7. Other third-party services
- Google Fonts: font files may be requested from Google servers.
- jsDelivr: the Excel export library is loaded only when you request an Excel export.
- External links: linked websites have their own privacy practices and are not controlled by PeptideCalc.
8. Data retention
Locally saved calculator results remain in your browser until removed. Analytics retention is controlled through the associated Google Analytics property. We do not operate a server-side database of calculator results.
9. Children’s privacy
This website is not directed to children under 13 and is intended for adults. We do not knowingly collect personal information from children.
10. Your choices and rights
Depending on your location, you may have rights to access, correct, delete, restrict, or object to processing of personal information. Because calculator results are stored locally, you can delete them directly using “Clear all” or browser controls. For other requests, contact dev@evetrend.com.
11. Policy changes
We may update this policy when website features, analytics, advertising, or legal requirements change. The latest revision date appears at the top of this page.
