What stays on your device
Your puzzle progress, guess history, and stats (games played/solved, streaks) are saved only in your browser's local storage. They're never sent to a server, and we have no accounts or logins — that data belongs to your device and browser, not to us.
Analytics — Umami
We use Umami, a cookieless analytics service, to see which puzzles get played and whether people finish/share them. It records page visits (which page, roughly when, your browser/device type, and the general region your traffic comes from) and a handful of named events (e.g. a puzzle being solved or failed, or the share/copy buttons being used) tagged with which puzzle they came from.
Umami does not use cookies or any local storage to track you, does not collect your name, email, or any way to identify you personally across visits, and does not sell or share this data with third parties — on its own, it would need no cookie consent banner. The banner described below exists because of advertising, not analytics.
Advertising — Google AdSense
We show ads served by Google AdSense to help keep Noodler free to play. Google and its advertising partners may use cookies, device identifiers, or similar technology to personalise the ads you see, based on your visits to this site and others.
If you're in the UK or EEA, a consent banner is shown the first time you visit, using Google's own certified consent tool. You choose there whether to allow personalised ads, and can change that choice at any time by reopening the banner (usually available via a small link in the page footer or Google's own privacy controls) or through Google's Ads Settings at adssettings.google.com. If you're outside a region where this consent is legally required, or you decline, you may still see ads — just not ones personalised to you.
For more detail on what Google and its partners do with this data, see policies.google.com/technologies/partner-sites and policies.google.com/technologies/ads.
Error tracking — Sentry
If the app crashes or hits an unexpected error, a report is sent to Sentry so we can fix it. That report can include technical details like the error message, which part of the code failed, your browser/OS, and the page URL you were on. It does not include your puzzle progress, guesses, or anything you typed.
Questions
This page describes the whole of what we collect — there is nothing else being tracked beyond what's listed above.
