Notes
What my extensions can see
A browser extension sits very close to your work. Here is how I treat that.
When you install a browser extension, you're letting it sit right next to your work: your tabs, your pages, sometimes your clipboard. I take that seriously, and I want to be plain about how I build them.
The fewest permissions I can manage
Each extension asks only for what its one job needs. A color picker has to read the page you point it at. It doesn't need your history, your bookmarks, or every site you visit. When the browser offers a narrower permission, such as access only when you click the extension, I use it.
Your work stays on your computer
Wherever I can, the work happens right in your browser. Palettes, measurements, and saved glyphs are stored on your machine. When a tool genuinely needs a server, such as cutting the background out of a large photo, the listing says so before you install, and I send only what that job requires.
No surprises later
An update can quietly ask for more than the original version did. Mine won't. If a tool ever needs a new permission, I'll explain why in plain words in the release notes before it ships.
If you have a question about what one of my tools touches, write to me. I'd rather answer it than have you guess.
