Privacy Policy

Last updated: 27 September 2026

What you type

Sizes and styles you enter are processed in your browser and are not sent to us. They appear in the page address so you can share a plan; anyone you send the link to can see those numbers. Blocks you mark as placed are kept only in the open page and are gone when you close it.

Comments

You can leave a comment on our tool pages. We only ask for a nickname and your message; we do not ask for your email address, and you do not need an account. Every comment is read by a person before it is published, and we remove or reject anything that contains personal information such as a real name, address, school, phone number, email address or social media handle. Please do not include personal information in your comments, especially if you are under 13.

To limit spam we store a one-way hash of your IP address together with your comment; we cannot turn it back into your IP address, and we delete it after 30 days. The comment form is protected by Cloudflare Turnstile, which checks that you are a person; it only loads once you start writing a comment. See the Cloudflare privacy policy for what Turnstile processes. Your browser also keeps a copy of comments you posted that are still waiting for review, so you can see them marked “Awaiting review”; it stays on your device only.

If you want a comment removed, contact us and tell us the page and the text of the comment.

Hosting

The site is served by Cloudflare. Like any web host, Cloudflare processes technical data such as your IP address and browser type to deliver pages and protect the site from abuse. See the Cloudflare privacy policy.

Advertising

This site may show ads served by Google. Google and its partners use cookies to show ads based on your visits to this and other websites. You can turn off personalised ads in Google Ad Settings, and read how Google uses data from sites that use its services. Where the law requires it, you will be asked for consent before these cookies are set.

Children

We do not knowingly collect personal information from anyone, including children under 13. The generators work without an account and without entering any personal details.

Changes

If this policy changes, the date at the top of this page will change too.
