This page explains how BREACH handles saved and shared plans, access information, and third-party advertising services.
Last updated: September 27, 2026
Plan data and browser storage
You can use BREACH without creating an account. Plan data, including names, placed operators and gadgets, lines, shapes, and notes, is saved in your browser’s storage (IndexedDB). BREACH does not provide an API for saving plans to the site operator’s server.
To delete a plan, remove it from My plans. Clearing this site’s data in your browser settings removes all plans stored in that browser. This does not delete exported files or copies you have already shared.
Plans do not automatically sync across devices or browsers. Browser data may be cleared, causing plans to be lost. Keep important plans as exported JSON files.
Your display language is saved in the same browser using localStorage. Clearing this site’s data also removes that preference.
Sharing links and files
A shared URL contains a compressed snapshot of your plan after #board=. Anyone who has the URL can load the data, including the plan name and notes, and save it in their own browser. Exported JSON files also contain plan data.
The site operator cannot revoke a shared URL or file, or delete copies from someone else’s browser. Copies may also remain in chats or other places where you shared them. Avoid including personal information or anything you do not want to disclose, and check the contents before sending.
See the guide for instructions and an explanation of how sharing works.
Site access information
When serving pages and images, the hosting service may process and record ordinary access information, such as your IP address, access time, requested resource, and browser information. This is separate from the plan data stored in your browser.
Advertising and cookies
This site uses Google AdSense advertising code. Third-party vendors, including Google, may use cookies to serve ads based on your previous visits to this and other websites. Google and its partners use advertising cookies to display ads according to your settings and other factors.
Loading advertising services may send information such as the URL of the page you visit and your IP address to Google. Identifiers such as cookies may be stored or accessed. This information is used for purposes including ad delivery, measurement, fraud prevention, and ad personalization according to your settings.
You can manage personalized advertising through Google’s ad settings. You can also manage or delete cookies in your browser. Turning off personalization does not necessarily stop ads from appearing.
Updates to this page
We will update this page when features or the use of third-party services change.
