Privacy Policy

Last updated: 2026-08-03

1. Information we collect

This calculator requires no account and collects no personal information. The values you enter — your dog's age in years and months and its size class — are processed entirely inside your own browser. They are not transmitted to us, not stored on a server, and never received by us in any form. There is no backend: the site is a set of static files plus JavaScript that runs on your device.

2. Cookies and third-party advertising

This site may display third-party advertising, including Google AdSense. Third-party vendors, including Google, use cookies (such as the DoubleClick cookie) to serve ads based on a user's prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to users based on their visits to this site and/or other sites on the internet. You may opt out of personalised advertising by visiting Google Ads Settings, or opt out of a third-party vendor's use of cookies for personalised advertising at aboutads.info. Users in the EEA and UK may also be shown a consent prompt where required by law.

3. Analytics

We may use privacy-friendly, cookie-free aggregate analytics (for example Cloudflare Web Analytics) to count page views and understand which pages are useful. No personally identifying information is collected, and the numbers you enter into the calculator are never included in analytics data.

4. Local storage

The calculator may read preset values from the page URL (for example a preselected age or size when you follow a link from one of our guide pages). We do not require cookies for the tool itself to function.

5. Affiliate disclosure

Some links on this site may be affiliate links, meaning we could earn a commission if you sign up for or purchase a product through them. This never changes the price you pay, and it does not influence the formulas, figures or recommendations on this site. Where a page contains affiliate links we aim to make that clear on the page itself.

6. Your choices

You can block or delete cookies in your browser settings; the calculator will continue to work. You can also use the site with an ad blocker. This service is not directed at children under 13 and we do not knowingly collect information from them.

7. Not medical advice

All results on this site are estimates generated by published or conventional formulas, as described on the about page. They are not veterinary advice and must not be used to diagnose or treat any animal.

8. Changes to this policy

If this policy changes, the "last updated" date above will change with it. Material changes will be reflected on this page rather than announced separately.
