Privacy policy
Effective 14 October 2026
KoiKnife is published by LIBCSYSTEMS LLC. The short version: KoiKnife does not collect, store or share any personal data.
What the app collects
Nothing. There are no accounts, no sign-in, no analytics, no advertising, no tracking and no third-party SDKs that collect data.
What stays on your device
Your "My Koi" wishlist and your best quiz score are saved only on your own device, using the operating system's standard app storage. They are never sent to us or anyone else, and they are deleted when you delete the app.
Links that leave the app
Buttons to call, get directions or visit a website hand off to your phone dialler, maps app or browser. What those apps do is governed by their own privacy policies.
Children
KoiKnife collects no data from anyone, including children.
Changes
If this ever changes, this page will be updated before any app version that collects data is released.
