Privacy Policy
What DogCalcs does and does not collect. Calculations run entirely in your browser and nothing you enter is transmitted or stored.
Last updated September 2026
The short version
Everything you type into a calculator on this site stays on your device. There is no account, no login, and no database of your dog. The pages are static files served from a CDN. The only things that leave your browser are the page requests themselves, a cookieless page-view count, and an email address if you deliberately choose to submit the signup form.
Calculator inputs
Weights, ages, amounts and every other value you enter are processed by JavaScript running in your own browser. They are never sent to a server, because the calculators do not talk to one. Closing the tab discards them.
Cookies
This site sets no cookies of its own and does not use browser storage to track you across visits. That is also why there is no cookie banner: there is nothing to consent to.
Server logs
The site is hosted on Cloudflare. Like any web host, Cloudflare records standard request information such as IP address, user agent, requested URL and timestamp, and uses it to serve pages, mitigate abuse and protect against attacks. We do not combine that data with anything else, and we do not use it to identify individuals.
Analytics
This build ships no analytics at all. If cookie-free aggregate analytics are switched on, this page describes exactly what they collect before they go live.
Email list
The home page has a tips signup box. If you enter an address there, it is sent to a small function that runs on the same Cloudflare account that serves this site and stored in a private key-value store owned by DogCalcs. No email provider, advertiser or other third party receives it at that point. Nothing else on the site sends anything anywhere.
We use your address to send occasional tips and updates about the calculators, and for nothing else. We do not sell it, rent it, or pass it to anyone beyond the service that delivers the messages. Every email carries an unsubscribe link, and unsubscribing removes the address. To have it removed without waiting for an email, contact us.
Submitting a signup form is the only action on this site that transmits anything you have typed. Calculator inputs remain entirely in your browser, before and after you sign up.
Third parties
The site loads no third-party fonts and no advertising or tracking scripts.
If affiliate links are added to any page, they will be disclosed in line with our affiliate disclosure, and clicking one will take you to that retailer, whose own privacy policy then applies.
Children
This site is intended for adults responsible for a dog and does not knowingly collect information from children.
