Cookie Policy

Last updated: August 02, 2026 · Zinthi LLC

This Cookie Policy explains how Zinthi LLC ("Company," "we," "us," and "our") uses cookies and similar technologies to recognize you when you visit our website at https://doodle.zinthi.io ("Website"). It explains what these technologies are and why we use them, as well as your rights to control our use of them.

In some cases we may use cookies to collect personal information, or that becomes personal information if we combine it with other information.

01 What cookies & storage we use

in plain terms

Only the bare minimum to make the game work — remembering who you are during a session and letting you rejoin a room. No ad trackers, no analytics spying on you.

What are cookies?

Cookies are small data files that are placed on your computer or mobile device when you visit a website. Cookies are widely used by website owners in order to make their websites work, or to work more efficiently, as well as to provide reporting information.

Cookies set by the website owner (in this case, Zinthi LLC) are called "first-party cookies." Cookies set by parties other than the website owner are called "third-party cookies." Third-party cookies enable third-party features or functionality to be provided on or through the website (e.g., advertising, interactive content, and analytics). The parties that set these third-party cookies can recognize your computer both when it visits the website in question and also when it visits certain other websites.

doodle! sets one cookie, and only if you sign in. It is called refresh_token, and it is what keeps you signed in without asking for your password again. It cannot be read by JavaScript running on the page, it is sent only over a secure connection, and it is deleted when you log out. We store only a hashed form of it on our servers, never the value held by your browser.

Everything else doodle! keeps in your browser is local storage rather than a cookie. Playing as a guest sets no cookie at all.

zinthi_doodle_nameThe display name you choseEssential (localStorage)Until cleared

Browser storage that is not a cookie

doodle! keeps your guest identity in your browser's local storage rather than in a cookie. Local storage is not transmitted automatically with your requests the way a cookie is; the values are read by the game and sent only when you join or rejoin a game. They remain in your browser until you clear its storage for this site.

02 Why we use them

in plain terms

To keep you logged in, let you hop back into a game, and keep the service secure. That's the whole list.

We use cookies and browser storage for technical reasons only — because they are required for the Website to operate. This is what is meant by "essential" or "strictly necessary."

Specifically, they are used to keep you signed in to your account, to let a guest keep their seat in a room and rejoin after a disconnection, and to remember the display name you chose.

We do not use cookies or similar technologies for advertising, cross-site tracking, or analytics profiling, and we do not permit third parties to do so through our Website.

04 Targeted advertising

in plain terms

No ads. No ad networks, nothing following you to other sites. That's a promise, not a setting.

We do not serve targeted advertising. We do not permit third parties to serve advertising through the Services, and we do not share information with advertising networks or use it to build an interest profile about you.

05 Changes & contact

We may update this Cookie Policy from time to time in order to reflect, for example, changes to the cookies we use or for other operational, legal, or regulatory reasons. Please therefore revisit this Cookie Policy regularly to stay informed about our use of cookies and related technologies.
