This policy explains what happens to information when you use Peptide Calculator at https://peptidecalculator.live. It is written to be read, not to be survived.
Information we collect
We do not ask you to create an account, and we do not collect names, email addresses or other personal details directly, except where you choose to send them through the contact form described below. There is no login, no profile and no user database.
What you enter on the site
Everything you type into a calculator on this site stays in your browser. Vial sizes, water volumes, doses, costs and cadences are computed by JavaScript running on your own device, and none of them is transmitted to this site, to a database or to any third party. There is no server side calculation and nothing to store.
Your inputs are mirrored into the address bar so that a bookmark or a shared link reopens the same calculation. A URL you copy therefore contains the values you entered; that is under your control, and clearing the query string removes them. If you share such a link, the person you share it with sees those values.
We do not ask for, and do not want, health information. A dose you type is never sent anywhere, so it is never received, logged or profiled by us.
Browser storage
The site stores one small value in your browser's local storage: your theme preference (light, dark or system). It is first party, stays on your device, and does not identify you. Clearing your browser storage removes it.
Analytics
We use Google Analytics to understand which pages people find useful and where the site falls short. It processes technical and usage information such as pages viewed, approximate location derived from IP address, device and browser type, and referring site. IP anonymisation is enabled.
Google explains its own handling of this data in the Google privacy and terms documentation .
Site performance monitoring
Separately from Google Analytics, this site uses Cloudflare Web Analytics (also called Cloudflare RUM), a first party performance monitoring tool from Cloudflare, which already hosts and delivers the site. It reports aggregated performance and usage metrics such as page load times, resource timing, approximate geographic region, and device and browser type. Cloudflare Web Analytics does not use cookies or any client side identifier to track you across visits or across other websites.
Cloudflare describes this in its own Web Analytics documentation .
Session recording and heatmaps
We use Microsoft Clarity to understand how visitors interact with the site through features such as session replays and click/scroll heatmaps. Clarity captures behavioral metrics and session data to help us improve site usability and user experience. Website usage data is captured using first- and third-party cookies and other tracking technologies. For more details on how Microsoft collects and processes this data, see the Microsoft Privacy Statement .
Advertising
This site displays advertising through Google AdSense. Google and its partners may use cookies or similar technologies to serve and measure ads, including personalised ads based on your activity.
You can review and change what Google uses for advertising at My Ad Center .
Contact form
The contact form is delivered by Web3Forms, which forwards your message to our inbox by email. The name, email address, optional subject and message you type are transmitted to Web3Forms for that purpose. We do not store your message anywhere else, and we use your address only to reply.
Hosting and security
The site is served through Cloudflare. As part of delivering and protecting the site, Cloudflare processes technical request information such as IP address, browser and device information, and request timing. This happens for every visit and is a normal part of how the site reaches you safely.
Data retention
We do not operate a database of visitors, so there is nothing on our side to retain. Information held by the third parties named above is retained according to their own policies.
Children's privacy
This site is not directed at children, and we do not knowingly collect information from them. If you believe a child has sent us information through the contact form, get in touch and we will delete the message.
Your choices
- Clear local storage to remove your saved theme preference.
- Block or clear cookies in your browser settings.
- Manage Google advertising preferences through My Ad Center.
Changes to this policy
This policy may be updated as the site changes. The date at the top of this page is updated whenever that happens.
