Privacy

Vetrule has no account, no sign-in, no analytics and no advertising. Every calculation runs on your iPhone or iPad, and Vetrule itself sends no data anywhere.

The app collects no personal information, so none is provided to third parties.

The patient bar keeps the species, weight and optional name of your recent patients. They are stored only on your device, and we never receive them.

Like the rest of your app data, they go into your own iCloud or device backups, under your Apple account. Deleting the app removes them from the device.

This button opens your own mail app with a draft addressed to hello@vetrule.com. The draft lists the calculator, the formula version, the app version, your language and region setting, and the numbers on screen, so we can check the result.

Nothing is sent unless you send the email. You can edit or delete anything in the draft first; if it includes a patient name, you can take it out. When you do send it, we use the email to reply to you and to check the calculation.

Vetrule Pro is bought through the App Store, and Apple processes the purchase. We don’t receive your payment details.

No cookies, no analytics, no trackers and no forms. Fonts load from Google Fonts, so your browser connects to Google’s servers to fetch them. The site is hosted on Cloudflare.
