Privacy Policy

Last updated November 3, 2026

This policy explains what information PetCalcHQ ("we", "us", "our") collects when you use petcalchq.com (the "site"), why we collect it, who we share it with, and the choices and rights you have. Our Cookie Policy lists the cookies we use in more detail.

Summary

• Our calculators run in your browser. The numbers you type are not sent to us.
• Analytics and advertising cookies are used only if you allow them in our cookie banner. You can change your choice at any time with the Cookie settings link at the bottom of every page.
• If you contact us, we use your message only to reply.
• We do not sell your personal information.

Calculator inputs stay on your device

Our calculators run entirely in your web browser. The details you enter, such as your pet’s weight, age or dates, are not sent to us or stored on our servers. We remember a couple of settings in your browser's local storage: whether you prefer US or metric units, and your cookie choices. You can clear them at any time by clearing your browser's site data.

Information you send us (contact form)

If you use our contact form, we receive the name, email address, subject and message you enter, the page you sent it from, and, for security and spam prevention, your IP address and browser type. If you email us, we receive your email address and message. We use this only to read and answer your message, to fix errors you report, to improve the site, and to protect the form from abuse. Messages are stored in our site administration system, which runs on our hosting provider's servers. We keep them only as long as we need them for these purposes, normally no longer than 24 months, and then delete them. We never sell this information or add you to a mailing list.

Log data

Like most websites, our hosting provider automatically records basic technical information when you visit, such as your IP address, browser type, the pages requested and the time of the request. These logs are used for security and to keep the site running, and are deleted on the host's normal schedule.

Cookies and your consent

Cookies are small text files a website stores in your browser; similar technologies include local storage and tracking pixels. We group them into three categories:

• Necessary (always on): needed for the site to work, such as remembering your unit setting and your cookie choices. These do not track you.
• Analytics (off unless you allow it): helps us understand how the site is used.
• Advertising (off unless you allow it): lets advertising partners show more relevant ads and measure them.

When you first visit, a banner asks for your choice: Accept all, Reject all, or Customize to choose each category. Until you choose, and if you reject, no analytics or advertising cookies are set by us or our partners. We use Google Consent Mode, which tells Google's tags that consent for analytics and advertising storage is "denied" by default and updates that signal only when you allow it. Your choice is stored in your browser for up to 12 months, after which we ask again. You can change or withdraw your consent at any time with the Cookie settings link in the footer; withdrawing does not affect processing that took place before.

If your browser sends a Global Privacy Control signal, we treat it as a request to opt out of advertising cookies and keep them off.

Analytics

Only if you allow analytics cookies, we may use:

• Google Analytics 4 (Google LLC / Google Ireland Ltd), to measure visits, pages viewed, how long people stay, the device and browser type, and approximate location (country or city, derived from your IP address, which Google Analytics 4 does not log or store). It sets cookies such as _ga and _ga_*. Learn more in How Google uses information from sites or apps that use its services. You can also opt out with the Google Analytics opt-out browser add-on.
• Microsoft Clarity (Microsoft Corporation), to see how pages are used through aggregated heatmaps and session replays (clicks, scrolling and mouse movement). Clarity masks text you type into forms. It sets cookies such as _clck and _clsk. See the Microsoft Privacy Statement and Clarity's cookie list.

We may also use Google Tag Manager to manage these tags. Tag Manager itself does not set cookies; the tags it loads follow your consent choices.

Advertising

We may show ads served by Google AdSense and other third-party vendors to keep the site free. When ads are shown:

• Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this site and other websites.
• Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the internet.
• If you do not allow advertising cookies, you may still see ads, but they will be non-personalized: based on the page you are viewing rather than your browsing history. Google may still use cookies for limited purposes such as frequency capping, aggregated ad reporting and fraud prevention.
• You can opt out of personalized advertising at any time in Google's My Ad Center, and opt out of some third-party vendors' use of cookies for personalized advertising at www.aboutads.info/choices (US), youradchoices.ca (Canada) or www.youronlinechoices.eu (Europe and the UK).
• Learn more in How Google uses cookies in advertising.

Only if you allow advertising cookies, we may also use the Meta Pixel (Meta Platforms, Inc. / Meta Platforms Ireland Ltd) to measure the results of our ads on Facebook and Instagram and to show our ads to people who have visited the site. It sets cookies such as _fbp and sends Meta information about your visit, such as the page viewed and your browser and device. See Meta's Privacy Policy; you can control the ads you see in your Facebook ad preferences.

Visitors in the European Economic Area, the UK and Switzerland will be asked for consent through a consent message that meets Google's requirements before personalized ads are shown.

Who we share information with

We share information only with service providers that help us run the site: our hosting provider, and, if you allow them, the analytics and advertising partners named above. These partners may process data in the United States and other countries. Where personal data from the EEA or UK is transferred, they rely on safeguards such as the EU-US Data Privacy Framework and the European Commission's Standard Contractual Clauses. We may also disclose information if the law requires it.

Legal bases (EEA and UK visitors)

Under the GDPR and the UK GDPR, we process personal data on these legal bases:

• Consent for analytics and advertising cookies and similar technologies. You can withdraw it at any time.
• Legitimate interests for answering your messages, keeping the site secure, and the necessary storage that makes the site work.
• Legal obligation where the law requires us to keep or disclose information.

Your rights under the GDPR and UK GDPR

If you are in the EEA, the UK or Switzerland, you have the right to:

• access the personal data we hold about you and get a copy of it;
• have inaccurate data corrected;
• have your data deleted;
• restrict or object to our processing, including processing based on legitimate interests;
• data portability;
• withdraw consent at any time, for example through Cookie settings;
• complain to your local data protection authority (in the UK, the Information Commissioner's Office).

Your rights under US state privacy laws (including the CCPA/CPRA)

If you live in California or another US state with a privacy law, you have the right to:

• know what personal information we collect, use and disclose, and to access it;
• delete the personal information we hold about you;
• correct inaccurate personal information;
• opt out of the "sale" or "sharing" of personal information, including sharing for cross-context behavioral (targeted) advertising;
• not be discriminated against for using these rights.

We do not sell personal information for money. Advertising and analytics cookies, if you allow them, may count as "sharing" for targeted advertising under California law. To opt out, choose Reject all in the cookie banner or turn off Advertising in Cookie settings; we also honor the Global Privacy Control signal. In the past 12 months, the categories of personal information we may have collected are identifiers (such as name, email and IP address), internet activity (such as pages viewed, if you allowed analytics) and approximate location, for the purposes described in this policy.

How to make a request

To use any of these rights, contact us using the details below. We will respond within the time the law requires (usually 30 days under the GDPR and 45 days under the CCPA), and we may need to confirm your identity first. You may also use an authorized agent where the law allows.

Children

The site is intended for a general audience and is not directed to children under 13 (or under 16 in the EEA and UK). We do not knowingly collect personal information from children. If you believe a child has sent us personal information, contact us and we will delete it.

Security

The site is served over HTTPS, and access to messages sent through our contact form is restricted and password-protected. No method of transmission or storage is completely secure, but we work to protect your information.

Links to other sites

Our pages may link to other websites. We are not responsible for their content or privacy practices.

Changes

We may update this policy from time to time. The date at the top shows when it last changed. If we make a significant change to how we use cookies, we will ask for your consent again.
