1. Introduction
Structure Canvas ("we," "our," or "us") operates this website to provide a free, browser-based tool for creating floor plans and building drawings. This Privacy Policy explains how we collect, use, and protect information when you use our site, including our use of cookies and participation in advertising programs such as Google Ads.
2. Information We Collect
Drawing data: All Structure Canvas work (images you upload, shapes you draw, measurements, and project files) is processed and stored only in your browser or on your device when you save a Structure Canvas file (.bdf). We do not collect, store, or transmit your drawing content to our servers.
Usage and advertising: When you visit our website, we or our partners (such as Google) may collect information that your browser sends automatically, including your IP address, browser type, approximate location, and how you interact with our site. This may be used to show you relevant ads (e.g., via Google Ads) and to understand how the site is used.
3. Cookies and Similar Technologies
We use cookies and similar technologies for the following purposes:
- Essential: Cookies necessary for the site to function (e.g., preferences, session state).
- Advertising: We may allow third parties, including Google, to use cookies and similar technologies to show you ads based on your visits to our site and other sites. Google uses this to serve ads and may collect information as described in Google's Privacy Policy and Advertising policies.
- Analytics: We may use analytics tools that set cookies to understand how visitors use our site (e.g., page views, traffic sources).
You can control or delete cookies through your browser settings. Disabling certain cookies may affect site functionality or ad relevance.
4. Google Ads and Third-Party Advertising
We may participate in Google Ads and other advertising programs. Third-party vendors, including Google, may use cookies and other technologies to serve ads based on your prior visits to our website or other websites.

5. How We Use Information
We use the information we collect to operate and improve the site, to personalize and measure the effectiveness of advertising, and to comply with legal obligations. We do not sell your drawing data; it remains on your device.
6. Data Retention and Security
We retain usage and advertising-related data only as long as necessary for the purposes described in this policy or as required by law. We take reasonable steps to protect information we hold, but no internet transmission is completely secure.
