Privacy Policy
Who we are
GLP1Cost.org is a service operated by Anthony K C Fong. For privacy inquiries, contact privacy@glp1cost.org.
GLP1Cost is built to need as little of your data as possible. The calculator runs entirely in your browser. Your weight, height, dose, insurance details, and any other inputs you type into the calculator never leave your device and are never sent to our servers. This page explains exactly what we do collect, why, and who else touches it.
What we collect
- Anonymous pageview data — which pages you visit, where you came from (referrer), the country and device type Plausible can infer from your IP. Plausible is cookie-free and does not track you across other websites. No personal identifiers are collected. See Plausible's data policy.
- Email address — only if you voluntarily enter it on the /updates page or another newsletter form. We use it solely to send you GLP-1 cost and clinical updates. We never sell or share your email. You can unsubscribe at any time using the link in any email we send.
- Standard server logs — our hosting provider (Vercel) and CDN (Cloudflare) automatically log IP addresses, user-agent strings, and request paths for security and abuse-prevention purposes. These logs are retained briefly and not used to build profiles of you.
What we don't collect
- No user accounts, no passwords, no profiles.
- No calculator inputs (your weight, height, dose, insurance, etc. are processed entirely in your browser and never transmitted to us).
- No health information beyond what's in our public clinical content.
- No sale of your personal information to anyone, ever.
- No tracking across third-party sites.
Third parties we use
The full list of services that may handle data on our behalf:
- Vercel — hosting and serverless functions
- Cloudflare — DNS and edge caching
- Plausible — privacy-friendly analytics (cookie-free)
- Resend — email delivery for newsletter and transactional messages
- Google AdSense — display advertising (planned, not yet active). When ads are added, AdSense may set cookies for ad personalization. We will update this page and add a cookie consent banner before that goes live.
Cookies
Today, GLP1Cost sets no cookies of its own. Plausible analytics is cookie-free by design. If we add ads or other features that require cookies in the future, we will display a cookie banner and update this policy before doing so.
Affiliate links and click tracking
Links beginning with /go/ are affiliate redirects. When you click one, we redirect you through our server to a partner site. The partner may set its own cookies once you arrive — that is the partner's tracking, governed by their privacy policy, not ours. See our Affiliate Disclosure for details on which partners we work with.
Your rights
Depending on where you live, you may have rights under the GDPR (EU/UK), CCPA/CPRA (California), or other privacy laws to:
- Know what personal data we hold about you
- Request deletion of that data
- Request correction of inaccurate data
- Opt out of any sale of personal data (we don't sell, but you can confirm)
- Withdraw consent for newsletter emails by unsubscribing
Since we collect very little personal data to begin with, most of these requests will consist of unsubscribing from the newsletter (one-click in any email). For anything else, contact us at the address below.
Children
GLP1Cost is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has submitted information through our site, contact us and we will delete it.
International users
Our hosting and email infrastructure is operated from the United States. By using GLP1Cost, you understand that any data we do collect may be processed in the United States. Plausible analytics is hosted in the EU.
Updates to this policy
We will update this page when our data practices change. Material changes will be flagged on the homepage or in our newsletter. The "last updated" date below tells you when the policy was last revised.
