Quadle is a free puzzle game published by Stringband Games ("we", "us"). This page explains what information Quadle collects, how it's used, and the choices you have. Quadle has no user accounts. Gameplay and saved progress stay on your device; limited gameplay events are sent to Cloudflare to help us understand how much the game is played.
Your wins, losses, streaks, and daily-puzzle progress are saved using your browser's local storage, directly on your device. We do not upload your saved board or full game history. Clearing your browser's site data for quadle.io deletes your locally saved progress and stats.
When you place your first tile or finish a game, we send a small event to our Cloudflare-hosted endpoint. Events record the game mode, start or win/loss result, loss reason (such as giving up or running out of time), tiles and undos used, and the current streak. Cloudflare adds the receipt time. We use this information to count games and understand results by mode, not to identify individual players.
These events contain no player identifier, advertising identifier, saved board, or personal contact details. Our analytics dataset does not store IP addresses, browser information, or referring pages. No tracking cookies are set by this gameplay analytics feature. Cloudflare still processes network information to deliver requests, as described below. Analytics Engine retains these events for three months. Clearing local game data does not delete previously received events, which we cannot associate with an individual player.
Quadle shows ads served by Google AdSense. Google, as a third-party vendor, uses cookies and similar technologies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the internet.
Quadle is hosted on Cloudflare. Like most web hosts, Cloudflare may process standard technical information (such as IP address and request metadata) as part of delivering the site and analytics requests, governed by Cloudflare's own privacy policy.
Quadle is not directed at children under 13, and we do not knowingly collect personal information from children. Since Quadle has no accounts and no data-entry beyond gameplay itself, no personal information is ever knowingly requested from anyone, regardless of age.
Because Quadle keeps essentially everything on your own device, you're in direct control of it: clear your browser's local storage for quadle.io to erase your saved stats and progress, and use the ad opt-out links above to control personalized advertising.
If this policy changes, the "Last updated" date at the top of this page will change with it. We encourage checking back occasionally if you have concerns.
