Privacy

Short version: we do not collect your health information.

Last updated November 3, 2026.

The injection site logbook

Everything you enter in the logbook is saved in your browser's local storage on your own device. It is never sent to us or anyone else. We cannot see it, recover it or delete it for you. Clearing your browser data removes it. The backup link keeps a copy of your log inside the link itself (it is never sent to or stored on our servers), and the backup file option saves a copy as a file on your device.

Accounts

There are no accounts, logins or sign-up forms on this site.

Analytics and cookies

We use two analytics tools to count visits and see which pages are useful.

• Vercel Web Analytics does not use cookies and does not identify you across sites.
• Google Analytics uses cookies to count visits and see how people move around the site. Google receives your IP address, browser and device details, and the pages you view. We have turned off Google signals and ad personalization, so this data is not used to show you ads. Google's use of the data is covered byGoogle's privacy policy, and you can opt out with Google's browser add-onor by blocking cookies in your browser.

For both tools, we send only the page address without anything after a ? or #, so a logbook backup link is never recorded. Nothing you type into the logbook or the eligibility checker is sent to Google. Vercel Web Analytics counts which type of checker result was shown (for example, in or out of the label's BMI range, and the type of insurance chosen), without cookies or anything that identifies you. Our host, Vercel, also processes standard server logs (such as IP address and requested page) to deliver and secure the site. There are no advertising cookies. If we add advertising, we will update this page first.

Fonts and third parties

Fonts and the Vercel analytics script are served from this site's own domain. The only script loaded from another website is the Google Analytics tag.

Affiliate links

Some links on this site are affiliate links. If you follow one, the provider and its affiliate network may record that you came from this site so we can be paid a commission. That tracking happens on their sites, under their privacy policies. See our affiliate disclosure.
