Who is behind this

TinyHold is a non-commercial hobby project. The data controller is Jan Němec, contact info@tinyhold.cz.

What we store and why

• Account — your nickname, email and password (only as a hash, the password itself is not stored anywhere). We need them for signing in, the leaderboard and the match history.
• Matches with people — who played whom, when, how it ended and the record of the match's orders. It is used for the leaderboard, the history and to check that nobody cheated.
• Contact form — name (optional), email and the text of the message, so we can reply. The message is only saved and goes nowhere else.
• Visit counter and spam protection for the form — a daily fingerprint computed from the address and the browser with a random salt that is thrown away every day. The fingerprint can't tell who you are. We don't store your IP address, neither in the database nor in the web server's access log.
• Game against the computer — an anonymous record of the game: map, difficulty, your orders and the game version, without a name, account, IP address or cookies. It is used to improve the computer opponent. The record can't be linked to you. (When you close the browser tab, the browser also sends cookies with the request. The server doesn't read them and stores nothing from them.)
• Tournament entries (TournamentEntry) — when you signed up, your seed and the contact for your opponent that you filled in yourself (email, Discord…), so you can agree on a match. Only your current opponent can see the contact, and only when signed in. Results of tournament games are stored like other matches.

Legal basis: for the account and matches, performing what you ask for yourself (Art. 6(1)(b) GDPR); for the rest, a legitimate interest in running and protecting the site (point (f)).

Cookies

We use only necessary cookies: signing in and protecting forms against forgery. No advertising or analytics cookies, which is why there is no consent banner.

The lng cookie remembers the language you chose with the Česky / English switcher. It lasts 1 year and is only created after you click the switcher.

Who we share data with

Nobody, and we don't sell anything. The data sits on the server where TinyHold runs. When you write an email to info@tinyhold.cz, it goes through a mailbox at Seznam.cz.

How long

The account, until you delete it. After you delete the account, the email and password are removed and the nickname is replaced with an anonymous placeholder ("deleted player" in Czech). The match history stays, because it is also a record of your opponents, but without your name. We delete contact form messages on request. The contact for your opponent is deleted once the tournament ends or is cancelled, and when you delete your account.

Your rights

You have the right to access your data, correct it, have it erased, restrict its processing, move it, and object to it. You can delete your account with its data yourself in the account settings (Personal data), or else write to info@tinyhold.cz. You can lodge a complaint with the supervisory authority, the Czech Office for Personal Data Protection (uoou.gov.cz).
