Constelly is a free daily puzzle made by one person in Copenhagen, Denmark. It has no accounts and no server of its own, and it doesn't collect your name, email or any other personal details. It's paid for by ads from Google, which work as described below.

What's stored on your device

To remember your progress, Constelly saves a few small entries in your browser's local storage (all starting with constelly:):

the lines you've drawn in each puzzle you've started (today's or a past one), with its timer and hints used,
your results history and statistics (streak, times),
whether you've already seen the how-to-play screen.

This data never leaves your device — it isn't sent to us or anyone else. It's needed for the game to work, so no consent banner is shown for it. You can delete it at any time by clearing this site's data in your browser settings (this resets your stats).

Ads and cookies

Constelly shows ads from Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet. How Google uses information from sites that use its services.

If you're in the EEA, the UK or Switzerland, Google asks for your consent first, using a Google-certified consent message, and ads are only personalised if you agree. You can change your choice at any time with the Privacy and cookie settings link that Google shows on the site.

Anywhere, you can opt out of personalised advertising in Google's Ads Settings, or opt out of other vendors' use of cookies for personalised advertising at aboutads.info.

Analytics

Constelly counts visits with Cloudflare Web Analytics, to see how many people play and how fast the site loads. It sets no cookies, stores nothing on your device and doesn't identify you or follow you across other websites; Cloudflare only receives technical data about each page view (such as the page, the referring site, your browser type, country and load time). See Cloudflare's privacy policy.

Hosting

The site is hosted on GitHub Pages. Like any web host, GitHub may process technical data such as your IP address to deliver the site and keep it secure. See GitHub's privacy statement.

Sharing results

The Share button only copies text to your clipboard or opens your device's share sheet. Nothing is sent anywhere unless you choose to share it.

Your rights and contact

Constelly itself doesn't hold personal data about you, so there's usually nothing for us to access or delete — clearing your browser data removes your game data. For data Google collects through ads, see Google's privacy policy. If you have questions, write to hello@playconstelly.com. You can also complain to the Danish Data Protection Agency (Datatilsynet).
