CatKai

Terms of Use

Last updated: 2026-10-28

These Terms of Use ("Terms") govern your use of CatKai (the "App"), provided by Luca Ramseyer, Switzerland ("we", "us"). By downloading or using the App you agree to these Terms. If you do not agree, do not use the App.

1. The App

CatKai calculates the coat colours, patterns and other inherited traits that kittens of two cats can have, and helps you keep records of your cats, litters, weights, vaccinations and care schedules.

2. Genetic predictions are probabilities, not guarantees

The App's results come from a genetic model and from the information you enter. They are probabilities: a result of 25% means each kitten has a one-in-four chance, not that one kitten in four will have that trait.

  • Results can only be as accurate as the information you enter. Where a cat's appearance can hide a gene, the App counts every possible genotype unless you enter a DNA test result.
  • The App does not replace DNA tests, a veterinarian or professional breeding advice. Health, inbreeding and blood type information is provided for orientation only.
  • You alone are responsible for your breeding, health and sale decisions. We are not liable for the outcome of any mating, litter or sale.

3. Licence

We grant you a personal, non-exclusive, non-transferable, revocable licence to use the App on devices you own or control, as permitted by the rules of the store you obtained it from. You may not copy, modify, reverse engineer, resell or redistribute the App, except where the law expressly allows it.

4. Breeder Mode subscription

Some features ("Breeder Mode") require a paid subscription, offered monthly or yearly.

  • Payment is charged to your Apple ID or Google Play account when you confirm the purchase. The price is shown in the App before you buy.
  • The subscription renews automatically at the same price for the same period unless you turn off auto-renewal at least 24 hours before the end of the current period. Your account is charged for the renewal within 24 hours before the current period ends.
  • You can manage or cancel the subscription in your account settings: on iPhone and iPad in Settings → your name → Subscriptions; on Android in the Google Play Store → Payments & subscriptions → Subscriptions. Cancelling stops the next renewal; you keep Breeder Mode until the end of the period you paid for.
  • Purchases are processed by Apple or Google. Refunds are handled by them under their policies; we cannot issue refunds ourselves.
  • A free trial or introductory offer, if offered, ends when you are first charged; any unused part of it is forfeited when you buy a subscription.

5. Your data

Your cats, litters and records are stored on your device. You are responsible for keeping your device and its backups. If you delete the App or lose your device, data that was not backed up may be lost. How we handle personal data is described in our Privacy Policy.

6. Acceptable use

Do not use the App in a way that breaks the law, harms animals, or interferes with the App or with other people's use of it.

7. Intellectual property

The App, its genetic model, texts and design belong to us or our licensors. The information you enter remains yours.

8. No warranty

The App is provided "as is" and "as available". To the extent permitted by law, we make no warranty that the App is free of errors, always available, or that its results are correct or fit for a particular purpose.

9. Limitation of liability

To the extent permitted by law, we are not liable for indirect or consequential damages, lost profits or lost data, or for damages arising from decisions based on the App's results. Our total liability is limited to the amount you paid for the App in the 12 months before the claim. Liability for intent and gross negligence, and any liability that cannot be limited by law, remains unaffected.

10. Changes

We may update these Terms. The current version is always available at this address, with the date of the last update at the top. If you keep using the App after a change, the updated Terms apply.

11. Apple App Store

If you obtained the App from the Apple App Store:

  • These Terms are between you and us, not Apple. Apple is not responsible for the App or its content.
  • Apple has no obligation to provide maintenance or support for the App.
  • If the App fails to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price, if any. To the extent permitted by law, Apple has no other warranty obligation with respect to the App.
  • Apple is not responsible for addressing any claims by you or a third party relating to the App, including product liability claims, claims that the App fails to conform to legal or regulatory requirements, and claims arising under consumer protection, privacy or similar laws.
  • In the event of any third-party claim that the App infringes that third party's intellectual property rights, we, not Apple, are responsible for the investigation, defence, settlement and discharge of that claim.
  • You confirm that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
  • Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

12. Google Play

If you obtained the App from Google Play, the Google Play Terms of Service also apply. Google is not responsible for the App.

13. Governing law

These Terms are governed by Swiss law. Mandatory consumer protection law of your country of residence remains unaffected. The place of jurisdiction is the provider's domicile in Switzerland, unless mandatory law provides otherwise.
