Privacy policy

Last updated 14 November 2026. This policy explains what happens to your information when you use tierzilla.com. The site is run by Stonmark LLC, 30 N Gould St #63987, Sheridan, WY 82801, USA (“we”, “us”), which is responsible for your information. Questions go to hello@tierzilla.com.

The short version

• We have no accounts and never receive the boards or pictures you make.
• Google shows ads on the site and, if enabled, measures visits. Google uses cookies to do this.
• Visitors in the European Economic Area, the UK and Switzerland are asked for consent first, and anyone can change their choice with the Privacy choices link at the bottom of every page.

Your boards and pictures

Everything you put on a board, including pictures you add, is processed in your own browser. Pictures are shrunk on your device and saved in your browser’s local storage (under keys starting with tz:) so your board is still there when you come back. We do not receive or store them.

When you share a link, the board’s text cards, tier names and colours are packed into the link itself (after the # sign), which browsers do not send to our server. When you use Share on a phone, the picture of your board goes from your phone straight to the app you pick; it does not pass through us. Anyone you give a link or picture to can see that board.

Information we collect

• Server logs. Like every website, our server records each request: IP address, date and time, page requested, referring page and browser. We keep these logs for up to 30 days to keep the site secure and working, then delete them.
• Emails you send us. If you email us, we keep your message and address for as long as we need to deal with it, and no longer than two years.
• Cookies and similar technology set by Google for advertising and analytics, described below.

We do not ask for your name, we do not run accounts, and we do not sell personal information for money.

Cookies and local storage

• Local storage (ours): keeps your boards on your device. It is not a cookie, is never sent to us, and you can delete it by clearing this site’s data in your browser.
• Advertising cookies (Google): such as __gads, __gpi and cookies on doubleclick.net, used to show, measure and limit ads and to fight fraud.
• Analytics cookies (Google): such as _ga, used to count visits and see which pages are used, if we turn Google Analytics on.
• Consent cookies (Google): such as FCCDCF and FCNEC, which remember the choice you made in the consent message.

Advertising

We show ads through 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.

You can opt out of personalised advertising in Google’s Ads Settings, or opt out of some third-party vendors’ use of cookies for personalised advertising at aboutads.info (and youronlinechoices.eu in Europe). Read more in How Google uses cookies in advertising and How Google uses information from sites that use its services.

Analytics

We may use Google Analytics to count visits and see which pages and features are used, so we know what to improve. It collects information such as your approximate location, device, browser and the pages you view. We do not send Google anything you type on a board.

Fonts

Our main font is served from our own server. The Japanese and Korean pages load their fonts from Google Fonts, so Google receives your IP address when you open those pages.

Why we use your information (legal bases)

If you are in the European Economic Area, the UK or Switzerland, we rely on your consent for advertising and analytics cookies, and on our legitimate interest in running a secure, working website for server logs and for answering your emails.

Who receives it

Our hosting provider stores server logs for us. Google receives the information described above as our advertising and analytics provider. We share information with authorities only when the law requires it. Google may process information in the United States and other countries; transfers from Europe rely on the EU–US Data Privacy Framework and standard contractual clauses.

Privacy choices

If you visit from the European Economic Area, the UK or Switzerland, advertising and analytics cookies stay off until you choose in the consent message. You can change your choice any time with the Privacy choices link in the footer of every page, which opens the message again.

Visitors in US states with privacy laws can use the “Do not sell or share my personal information” option shown by Google’s message to turn off ad personalisation. Anyone can also turn off personalised ads in Google’s Ads Settings, block cookies in their browser, or clear this site’s data to remove saved boards.

Your rights

In Europe and the UK you have the right to access, correct or delete your personal information, to restrict or object to its use, to data portability, and to withdraw consent at any time. You can also complain to your local data protection authority.

In US states with privacy laws (such as California, Colorado, Connecticut, Virginia and others) you may have the right to know what personal information we hold, to access, correct or delete it, and to opt out of its “sale”, “sharing” or use for targeted advertising. We will not treat you differently for using these rights.

To use any of these rights, email hello@tierzilla.com with “Privacy request” in the subject. Because we have no accounts, the only personal information we hold about you is usually server logs and any emails you sent; information held by Google can be managed through your Google account and the links above.

Children

TierZilla is a general audience site and is not directed at children under 13. We do not knowingly collect personal information from them. Teachers can use TierZilla in class without any student accounts, because boards are never sent to us. If you believe a child has sent us personal information, email us and we will delete it.

Security

The site is served only over HTTPS. Because your boards stay on your device, there is no database of boards that could leak.

Changes

If this policy changes, we will update the date at the top of this page.
