LogoTurtle ("the extension") is an open-source LOGO (turtle graphics) interpreter that runs entirely inside your browser. Your privacy matters, and this policy explains exactly what the extension does and does not do with your data.
- We do not collect, transmit, or sell any personal data.
- No analytics, no tracking, no advertising, no remote code execution.
- Everything you type and draw stays on your device.
To remember your work between sessions, the extension saves the following using
Chrome's built-in storage API (chrome.storage.sync):
- Your selected UI language.
- The contents of the console editor (your LOGO program).
- The contents of the Global Procedures editor.
This data is stored locally and, if you are signed into Chrome with sync enabled, synchronised across your own devices by Google Chrome. It is never sent to the extension's author or any third-party server.
The extension requests a single permission:
storage— used solely to save and restore the settings described above.
It does not request access to your browsing history, tabs, web page content, clipboard, location, camera, microphone, or any other sensitive data.
The extension does not make network requests to load or execute remote code. In
keeping with Manifest V3, all code is bundled with the extension and runs in a
sandbox without eval(). The Help/About tabs contain some outbound links (for
example to the project page or the author's blog); these only open when you
click them.
LogoTurtle is designed to be safe for learners of all ages, including children. It does not collect any information from anyone.
Any changes to this policy will be published in this file in the public repository.
Questions about privacy can be raised via the GitHub issue tracker.
