Burrow is a small daily puzzle made by one person, Simon, in Croatia. It has no ads, no accounts, no cookies and no tracking. Questions or requests: hello@burrow.day.

What stays in your browser

Your arrows, scores, streaks, the sound setting and whether you have seen the how-to-play steps are kept in your browser's local storage. They never leave your device unless you share a result yourself. Clearing your browser data removes them.

What reaches the server

When you submit, the game sends this so everyone can see how the day went:

• the puzzle number,
• your score,
• a random id made by your browser, so the same result isn't counted twice.

To stop one machine from flooding a day with fake scores, the server also keeps a one-way hash of your IP address mixed with the day, so it changes every day and can't be turned back into the address. Your route is never sent. Nothing here is linked to a name, an email or an account. The scores are kept so the day's chart keeps working.

Legal basis: legitimate interest in counting results fairly (Art. 6(1)(f) GDPR).

Hosting

The site and the score database run on Cloudflare (Cloudflare, Inc.). The database is kept in the European Union. Like any web host, Cloudflare handles your IP address to deliver the pages and protect the site from attacks. See Cloudflare's privacy policy.

The fonts, pictures and sounds come from this site itself, so no other company is contacted while you play.

Sharing

The share buttons only open X, Facebook, Reddit or WhatsApp in a new tab with your score filled in. Nothing is sent to them until you post it yourself, and their own privacy policies apply there.

The shared link looks like burrow.day/s/26/12/15: the puzzle number, your score and the best possible score. That is all it carries, so the link preview can show a picture of the score. Nothing is stored when someone opens it.

Your rights

You can ask what is stored about you, and ask for it to be corrected or deleted, at hello@burrow.day. Since the scores only carry a random id, include the puzzle number and your score so I can find them. You can also complain to your data protection authority; in Croatia that is AZOP (azop.hr).
