Rotki
The portfolio tracker and accounting tool that respects your privacy.
Rotki is an open source asset analytics, tracking and management aplication. The mission of Rotki is to bring transparency into the crypto and financial sectors through the use of open source. Most importantly unlike virtually every other competing service which consists of closed source webapps onto which you are forced to hand over all your financial data, with Rotki your data is stored encrypted locally in your computer. It enables you to take ownership of your financial data.
