Who we are

Independent software.
No compromises.

Kaiyo Zero is one person, two apps so far, and a stubborn refusal to build anything worth ignoring.

Hi, I'm Chazic.

"I started Kaiyo Zero because I was tired of apps that treat users as a product. Ads on top of ads, mandatory signups before you can do anything, feature lists three screens long with nothing worth using."

"I wanted something cleaner. Software that respects the person using it. Honestly priced, honestly built, with nothing buried in the fine print."

"Kaiyo Notes came first. It's the note-taking app I always wanted and couldn't find. More will follow, each one held to the same standard."

The Kaiyo Zero rules
  1. 1 No ads — in any app, ever
  2. 2 No selling your data — it doesn't leave your device
  3. 3 No dark patterns — upgrade prompts are honest and skippable
  4. 4 No feature bloat — if it doesn't belong, it doesn't ship
  5. 5 Freemium done right — the free tier is genuinely useful

Kaiyo (海洋)

Kaiyo is the Japanese word for ocean. Vast, deep, always in motion. The wave across our logos takes its shape from Hokusai's Great Wave — something that looks effortless and hits hard. Software should feel the same.

More apps are coming.

Kaiyo Notes is the first. Each new app follows the same rules. Each one gets its own wave.
