Privacy Policy
Last updated: 4 April 2026
CritterCalcs (“the site”, “we”) is operated by Dan Dadovic from the United Kingdom. This policy explains what data we collect, why, and your rights under the UK GDPR and EU GDPR.
What we collect
Google Analytics 4 (consent-gated)
We use Google Analytics 4 (GA4) to understand how visitors use the site — which pages are popular, how long visits last, and which calculators are used most. GA4 collects anonymised usage data including page views, session duration, device type, browser, and approximate geographic location (country/city level).
GA4 is only loaded after you explicitly accept analytics cookiesvia the cookie consent banner. If you click “Reject” or close the banner without accepting, no analytics data is collected. You can change your preference at any time using the “Cookie Settings” link in the footer.
Cookies
We use a single first-party cookie to store your cookie consent preference (cc_consent). This cookie is essential for remembering whether you have accepted or rejected analytics cookies. It expires after 365 days.
If you accept analytics cookies, Google Analytics sets additional cookies (_ga, _ga_*) to distinguish unique visitors and sessions. These are set by Google under their standard analytics cookie policy.
Cloudflare Turnstile
Our feedback form uses Cloudflare Turnstile, a privacy-focused alternative to CAPTCHA, to prevent spam submissions. Turnstile does not use cookies for tracking and does not collect personal information. It verifies that the form submission comes from a real browser, not a bot. Cloudflare processes this verification under their privacy policy.
Feedback form (Resend)
If you submit the feedback form, we collect the information you provide: your name (optional), email address (optional), and message content. This data is sent to us via Resend, our email delivery service. We use it solely to respond to your feedback and do not add you to any mailing list. Your feedback data is retained for 12 months to allow follow-up, then deleted.
Calculator inputs
All calculator inputs (pet weight, breed, medication, etc.) are processed entirely in your browser. No calculation data is sent to our servers or any third party. Your calculator inputs are not stored, logged, or transmitted.
Legal basis for processing
We process data under the following legal bases:
- Consent — Analytics cookies (GA4) are only set after explicit consent.
- Legitimate interest — Essential cookies (consent preference) and spam prevention (Turnstile) are necessary for the site to function properly.
- Contract performance — Processing feedback form data to respond to your enquiry.
Your rights
Under UK GDPR and EU GDPR, you have the right to:
- Access the personal data we hold about you
- Rectify inaccurate personal data
- Erase your personal data (“right to be forgotten”)
- Restrict processing of your personal data
- Object to processing of your personal data
- Data portability — receive your data in a structured format
- Withdraw consent at any time (for analytics cookies, use the Cookie Settings link)
To exercise any of these rights, email privacy@crittercalcs.com. We will respond within 30 days.
International data transfers
Google Analytics data may be processed in the United States under Google's standard contractual clauses. Cloudflare processes Turnstile verification data in their global network under their DPA. Resend processes email data in the United States under their standard contractual clauses.
Children
CritterCalcs does not knowingly collect personal data from children under 16. If you believe a child has submitted personal data through our feedback form, please contact us and we will delete it promptly.
Changes to this policy
We may update this policy to reflect changes in our data practices or legal requirements. Material changes will be noted at the top of this page with the updated date. Continued use of the site after changes constitutes acceptance of the revised policy.
