Privacy Policy

Overview

n0n0gram.com (“we”, “us”) is a free puzzle game. We collect minimal data and do not sell personal information.

Data we store locally

Your in-progress puzzle state, solved puzzle history, and daily streak are stored in your browser's localStorage. This gameplay data stays on your device; the only information sent to our servers is the leaderboard data described below.

Leaderboards

To show daily and monthly rankings, the game sends a small amount of data to our servers (hosted on Upstash): a randomly generated device identifier, your chosen nickname, the puzzle number, and your solve time. The identifier is a random value created in your browser — it is not linked to your name, email, or any account, and we have no way to connect it to you personally. Nicknames are public on the leaderboards, so pick one you are comfortable sharing. No email address is collected, no account is required, and no tracking cookies are used for this feature.

Cookies & Analytics

We use Vercel Analytics, a privacy-friendly, cookieless service that measures aggregate traffic (pages visited, country, device type) without tracking individuals or storing personal data.

We also use Google AdSense to serve ads. AdSense may set cookies and collect usage data to show relevant ads, subject to Google's Privacy Policy.

We do not use cookies for any purpose other than those required by advertising partners. You can opt out of personalised advertising via Google Ad Settings.

Children's privacy

This site is suitable for all ages. We do not knowingly collect personal information from children under 13.
