Some here might find darkfolio useful - it has no signups and a generous free tier. 

It has a few innovative features, foremost of which is verifiably blind pricing. Every price refresh from every user downloads the whole price universe, instead of just the assets the user watches or holds. And this is something that each user can verify for themselves. The verification guide is here: [https://getdarkfolio.app/privacy/](https://getdarkfolio.app/privacy/).

Whereas blind pricing hides what you hold, Tor hides who you are. And users can toggle Tor within the app, through an implementation of Arti. 

Another feature that people here might have an interest in: a self-consistent system for plausible deniability called Ghost Mode. When enabled, every user can use two separated spaces to store watchlists/portfolios. One space for all the real stuff, and another for decoy cover. They look and behave similarly - pretty much the only difference between them rests in your intentions, how you choose to use them, in your mind. 

I'm a true believer, and the first $10k in net revenue (all Apple proceeds) goes straight to privacy causes. 

My main motivation is to get people off coinmarketcap/coingecko and similar with a much more useful and privacy-centric tool. Given our architecture and design, we have nothing to leak, and so will never contribute to the data honeypots that lead to wrench attacks. 

There are lots of other fun features. But I had the main ideas around New Years, and it's been a big undertaking, even with Claude Code. It just launched last week, and I'd still love constructive feedback.

I know that privacy tools receive extra scrutiny - and that's good! Although I cannot provide a reproducible build, given iOS requirements for the app, I do hope and plan to do so for an Android version. 

This is something I'm doing in my spare time - I'm an academic - but it's a long-term commitment. Because I really want to get people off portfolio apps that suffer leaks and breaches.
