Privacy Policy
Last updated: October 12, 2026
This policy explains what information PuppyWeightCalc collects when you use the site, and how it is used.
Information we collect
Calculator inputs stay in your browser. When you enter your puppy's age, weight, or breed, that information is processed on your device to produce the estimate. We don't receive or store the exact values you type.
If you email us, we receive your email address and message so we can reply. We don't use it for marketing.
Analytics
We use analytics tools (Vercel Analytics and Google Analytics) to understand which pages are visited and how the calculators are used. These tools collect aggregated, page-level information such as pages viewed and general device type. We don't track your individual calculator inputs or results.
Cookies
We use a small number of cookies: a language-preference cookie that remembers your settings, and analytics cookies that help us measure traffic. You can block cookies in your browser settings; the calculators will still work.
Advertising
We may display ads served by third-party vendors, including Google. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our sites and other sites on the internet. You may opt out of personalized advertising by visiting Google's Ads Settings at https://www.google.com/settings/ads.
Third-party services
Our site is hosted by Vercel and uses Google Analytics for measurement. These providers process limited technical data (such as IP addresses and pages visited) under their own privacy policies in order to operate the site.
Children's privacy
PuppyWeightCalc is not directed at children under 13, and we don't knowingly collect personal information from children.
Changes to this policy
We may update this policy as the site evolves. The “last updated” date at the top always reflects the current version.
