Too Long; Didn't Read
PayTrackr is a browser extension that lets you track and manage your micropayments to web monetized websites. Only you have access to your data and not even the web monetization providers can read your data. The extension is currently in beta testing so there will be changes anytime soon. The source code is hosted on GitHub and everyone is free to review, audit, and contribute to the PayTroutr codebase. PayTrunkr is 100% open source software. It is available in Chrome, Firefox and Chrome.
