Privacy Policy

Last Updated: June 10, 2026

Our Commitment to Privacy

PetCalcHub is designed to be private by default. We believe you should be able to use pet health tools without compromising your privacy. Here's exactly how we handle your data:

What We Collect

Nothing. All calculations on PetCalcHub happen entirely in your web browser using JavaScript. Your pet's weight, age, breed, and other information never leaves your device. We do not have servers that store or process calculator inputs.

Cookies & Analytics

PetCalcHub uses Google Analytics to understand overall site usage and improve our calculators. Google Analytics uses first-party cookies to collect anonymous usage data such as page views, session duration, and general geographic region. This data is aggregated and not linked to individual users. We use this information only to improve the website — we do not sell or share analytics data with third parties for marketing purposes.

You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on. The core calculator functionality works entirely without cookies — all calculations happen in your browser.

Third-Party Services

This site is hosted on Cloudflare Pages. Cloudflare may collect anonymized technical data (such as IP addresses and request logs) as part of their infrastructure. This is standard for any website and is governed by Cloudflare's Privacy Policy.

Children's Privacy

PetCalcHub is not directed at children under 13. We do not knowingly collect any personal information from children.

Medical Disclaimer

PetCalcHub is an educational tool — not a substitute for veterinary care.

The calculators and AI-generated insights on this website provide estimates based on published veterinary formulas and general knowledge. They are designed for informational and educational purposes only.

You should NOT:

  • Use calculator results to diagnose or treat any medical condition
  • Delay seeking veterinary care based on information from this site
  • Administer medications or supplements based solely on calculator results
  • Ignore professional veterinary advice in favor of anything read here

In case of a medical emergency involving your pet, contact your veterinarian or the nearest animal emergency hospital immediately. For suspected poisoning, call ASPCA Animal Poison Control at (888) 426-4435 or the Pet Poison Helpline at (855) 764-7661.

Affiliate Disclosure

PetCalcHub participates in affiliate marketing programs, including the Amazon Associates Program and pet insurance affiliate programs. This means we may earn a commission when you click on or make purchases via affiliate links — at no additional cost to you. Affiliate relationships do not influence our calculator formulas or risk assessments, which are based solely on veterinary science. All affiliate content is clearly disclosed in accordance with FTC guidelines.

Amazon Associates Disclosure

As an Amazon Associate, PetCalcHub earns from qualifying purchases. Amazon and the Amazon logo are trademarks of Amazon.com, Inc. or its affiliates.

Our Amazon affiliate links connect to Amazon search results pages rather than individual product pages. This ensures links remain valid over time and that you always see the current price and availability displayed directly on Amazon at the time of viewing. PetCalcHub does not set, cache, or guarantee any prices — all pricing and availability information is provided by Amazon and is subject to change.

Product category recommendations are independently selected by our editorial team based on veterinary guidelines. We do not claim any product is "Amazon's Choice" or a "Best Seller" unless such status is visibly displayed on Amazon's own site at the time you click through. Rankings and recommendations are not influenced by commission rates.

Pet Insurance Affiliate Disclosure

PetCalcHub may earn a referral fee when you request a quote from pet insurance providers (such as Pets Best, Lemonade, Embrace, Trupanion, ASPCA, Spot, Healthy Paws, and Fetch) linked on our pet insurance calculator page. Quotes are free and carry no obligation. Insurance provider rankings are based on coverage features, customer satisfaction, and price transparency — not commission rates.
