What can be seen is a portfolio overview, which displays your balance, income, expenses and transfers, while you can upload transactions or sync to certain institutions. The Buxfer software provides for the addition and tracking of investment accounts, but doesn't offer many advanced investment tools. And as mentioned already, there is the option to sync to your Dropbox account, where the reports can be automatically saved as backups each day. However, you can still save a backup of your transactions, choosing the account, tags and date range, and then save into either a PDF, CSV, HTML, OFX, or QIF format.
The option to export the reports is also lacking.
