Fair call. I had to declare the behaviour so as a user you can make the best informed option for you.
Obsidian is an Electron app. In essence, it is running inside a sandboxed browser. Any web session that a plugin may create, is available for all plugins to use. It is currently not possible to limit a session for a particular pluginās usage.
That said, you have two easy options to work around this to ensure the privacy of your Amazon account:
- Logout from the pluginās settings after every use
- Donāt use the online Amazon sync. And instead upload the My Clippings.txt file on your Kindle device
