The app
Your solved levels, your stars and your Daily Hiku results stay on your phone; the widget reads them there. Everything is deleted if you delete the app.
From version 1.2 the app sends a few anonymous milestones so we can see how far players get: reaching 1, 9, 10, 20, 30, 40 or 50 cleared levels (and 100, 150, 200), solving a Daily Hiku board and its difficulty, and a Daily Hiku streak of 3, 7, 14, 30 days or more. They go to TelemetryDeck, a privacy-focused European analytics service, and contain nothing that identifies you: the install gets a random number that is hashed one way before it is sent. We use the numbers only to improve the game.
Daily Hiku on the web
Daily Hiku in the browser sets no cookies and sends no game data. Your results stay in your browser. The site counts visits with Cloudflare Web Analytics, which uses no cookies and does not follow you between sites: we see how many came and from which site, not who.
Hiku in ChatGPT and Claude
Hiku in ChatGPT and Claude is the same game as the website. The server that shows the boards keeps nothing about you or the conversation: it only learns which board was asked for, and the game sends no game data. What you write in the conversation is handled by ChatGPT or Claude under their own privacy policies. Hiku never sees it.
