There is one alternative that is not tracking and collecting your data and it is open source portfolio tracker called Rotki.
It is possible to import wallet addresses or integrate exchanges with API keys and all that is free but there is also paid version with more features.
Bitcoin and many other coins are supported and you can download it for Windows, Linux and Mac but there is no mobile application yet.
