About this extension
The extension tracks usage of saas services and collection of receipts from services that the user pay for through Cardboard. The extension asks Cardboard what the user subscribes to before reporting the usage. The extension reports if there are any matches to a given domain in the browser history. It reports the matched domains for each day of usage. So not full timestamps or full paths.
The receipts collected are only receipts related to payments that have been done through Cardboard. These are collected for accounting purposes.
The extension does not report any history prior to the installation of the extension without user explicit consent.
