Privacy Policy

Last updated: October 17, 2026

This policy describes how Size Comparison Game ("we") handles information when you use size-comparison-game.com (the "Service"). It also explains how that information is used, and how to contact us about it.

1. Acceptance

Please read this policy before you use the Service. By using the site, you agree to the collection and use described below. If you do not agree, do not use the Service.

2. Changes

If this policy changes, the new text is posted on this page with a new "Last updated" date. Continuing to use the Service after that date means you accept the revised policy. If you do not accept it, stop using the Service.

3. Information we collect

The Service does not ask you to create an account, and a round does not ask for your name or email.

• Scores kept on your device. Guess the Size can save your unit choice and recent scores in the browser's local storage, under the key scg-gts. That record stays on the device. It is not sent to us, and there is no profile to attach it to.
• Ordinary connection logs. The network that serves the site may keep, for a short time, the address of the page requested, the time, and the browser or device type. That is how a website stays up.
• Messages you send us. If you email tinaliu660@gmail.com, we have the address you wrote from and the message you sent, so we can reply.
• Page measurements. Google Analytics (Google LLC), measurement ID G-B35FCLTGDQ, may set a cookie and record the page you opened, a rough location, the device and browser, and how you reached the site.

The Service does not run advertising cookies or a mobile app. It does not read an advertising identifier.

4. How the information is used

A saved score is used only to show your Guess the Size record the next time you open that game on the same browser. Connection logs are used to serve the pages. Email is used to read and answer the message you sent. Google Analytics is used to count visits and see which pages are opened.

We do not sell scores, and we do not sell the address you email from.

5. Scores

We do not keep a copy of your rounds. Clearing the site's data in the browser deletes the saved Guess the Size record. The other games do not write that record.

6. Security

We take ordinary care to protect the information under our control. No transmission over the internet can be guaranteed completely secure. You send an email at your own risk.

7. Where information is processed

The site is served by Cloudflare and may be processed outside the country you are in. Those places may have different privacy laws from yours. If you do not want a page request handled that way, do not use the Service.

8. Other sites

Answer pages link to the public source of a measurement, such as a government page, a manufacturer page, or Wikipedia. We do not control how those sites collect or use information. Their own privacy pages describe that.

9. Do Not Track

Some browsers send a Do Not Track signal. The Service does not use that signal to change what the page does, and the Google Analytics tag still loads.

10. How long information is kept

A Guess the Size record lasts until you clear it, or until the browser drops it. Connection logs kept by the host last only as long as that host needs them to operate the site. Email you send us is kept long enough to handle the message, and longer if we need it for a legal obligation.

11. Children

The Service is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has sent us personal information, email tinaliu660@gmail.com and we will delete it.

12. People in the EEA, the UK, and Switzerland

If you use the Service from the European Economic Area, the United Kingdom, or Switzerland, Size Comparison Game is the controller of the information described above. We process connection logs because we need them to run the site. We process email because we need it to reply. Google Analytics processes page measurements for our interest in knowing which pages are used; Google's own policy describes what it keeps. The score record stays in your browser and is not sent to us.

Depending on where you live, you may ask us for access to personal information we hold about you, a correction, deletion, a restriction, or a copy you can take elsewhere. Email tinaliu660@gmail.com. We may ask you to confirm you are the person the request is about. You can also complain to the supervisory authority where you live or work.

13. Contact

Questions about this policy go to tinaliu660@gmail.com, or through the contact page. The rules for playing are on the terms page.
