Calculations happen on your device
You can use the calculator without an account. The pet selection, age inputs, size group, and calculation result are processed in your browser. This version does not send these entries to a server or save them in browser storage.
No tracking scripts or cookies
This release does not include analytics, advertising, third-party fonts, cookies, or tracking pixels. All calculator code and visual assets are served with the website.
Website delivery
The company hosting this website may process standard connection information, such as an IP address, requested URL, and browser details, to deliver and secure the site. That is separate from the calculator, which does not transmit your pet’s age inputs.
About this release
Pet Age Convertor is a free, independent educational tool. If analytics, advertising, or other data collection is added, this notice should be updated before those features are enabled.
