Terms of Service

Last updated: 2026-10-24

These terms apply to CatCalc (https://vonsoh.com) and to digital products sold through it. The site is operated by an independent creator based in China. Contact: tianxiemoyu@gmail.com.

Free tools and information

The calculators and articles are free and provided for general information only. They are not veterinary advice. Always ask your veterinarian about your cat's health, and contact a vet or pet poison hotline in an emergency.

Digital products

Products are downloadable PDF files. No physical item is shipped. Orders are processed by our online reseller and payment provider, which acts as the merchant of record and handles payment, taxes and invoices. Its own terms also apply to your purchase.

License

When you buy a product you get a personal, non-transferable license to download, print and use it for your own household as many times as you like. You may not resell, share, redistribute or claim the files as your own.

Refunds

See our Refund Policy.

Liability

The site and products are provided "as is". To the extent permitted by law, we are not liable for indirect or consequential losses arising from using the site or products. Nothing in these terms limits rights you have under consumer protection laws that apply to you.

Changes

We may update these terms. The date above shows the latest version.
