Privacy Policy

The short version

This site sets no cookies, uses no analytics or tracking, and loads nothing from other servers — no fonts, no scripts, no counting pixels, no embedded videos. There is no account, no comment section and no form. The free pages download without signing up for anything. That is why you see no consent banner here: there is nothing to consent to.

The one exception is our free browser games (Physicado Games): they keep your game progress on your own device, and if you play an event, your result appears in a public ranking. The section Physicado Games below explains exactly what that involves.

Who we are

MindMaze Publishing, the publisher of the Mystery Dots colouring books. This website is colorbynumberdots.com.

Server log files

Like every website, ours is delivered by a server, and that server keeps access logs: the address requested, the time, the amount of data sent, the browser type and the IP address. This is technically necessary to deliver the site and keep it secure. The legal basis is Art. 6(1)(f) GDPR, our legitimate interest in running the site. The logs are not merged with any other source and are deleted after a short time.

Hosting

The site is hosted by ALL-INKL.COM — Neue Medien Münnich, Hauptstraße 68, 02742 Friedersdorf, Deutschland. A data processing agreement under Art. 28 GDPR is in place; the servers are in Germany.

The colouring widget

The dot field you can colour in runs entirely in your own browser. Nothing you do there is sent anywhere, and nothing is stored on your device — reload the page and it starts over.

Physicado Games (Guacathlon)

Stored on your device. The game saves your records, your settings (sound, vibration), the nation and player name you chose, and a random device code in your browser's local storage. This is not a cookie and is never read by anyone else; it is needed so the game remembers your progress (§ 25(2) no. 2 TDDDG). You can delete it at any time by clearing the site data in your browser.

World ranking. When you finish an event, the game sends your result to our server: the event, your score, your nation, your player name and the date. Instead of the device code we store only a one-way hash of it, so your entries can be updated but not traced back to you. Results, player name and nation are publicly visible in the ranking, so please don't use your real name if you would rather stay anonymous. Weekly rankings start fresh every Monday; the all-time ranking is kept for as long as the game runs. Legal basis: Art. 6(1)(b) GDPR, because the ranking is part of the game you chose to play.

Android poll. If you answer the short question whether you would like an Android version, we store your answer and nation together with the hashed device code, so each device counts once. We only ever look at the totals.

Spam protection. To limit how often results can be sent, the server keeps a shortened hash of your IP address and the current day for one hour. The IP address itself is not stored. Legal basis: Art. 6(1)(f) GDPR, our legitimate interest in a fair ranking.

The games load nothing from other servers: fonts, flags and sounds come from our own server. To have your ranking entries removed, write to us with your player name.

Downloads

The PDF pages are ordinary files on our server. Downloading one needs no e-mail address, no account and no consent, and we cannot tell who downloaded what.

Links to Amazon and Gumroad

Simply viewing this site sends no data to either. That happens only when you click a link. From then on the privacy statement of that provider applies; both are based in the United States, so following such a link means a transfer to a third country.

Your rights

You have the right to know what data we hold about you and to have it corrected, deleted or restricted, the right to object, and the right to data portability. You may also complain to a data protection authority. Apart from the game ranking and the server logs described above, this site collects nothing, so there is in practice very little to ask about — but ask if you wish at MindMaze_Publishing@protonmail.com.

Changes

If we ever add something that does collect data — a newsletter form, for instance — this page will say so before it goes live.
