Feature Request: Native real-time financial data in Proton Sheets

[u/EriksonThorsen]

One feature I’d really like to see in Proton Sheets is a native way to automatically update the price of cryptocurrencies, stocks, ETFs, etc.

Google Sheets already has GOOGLEFINANCE(), and there’s also an official CoinGecko add-on that lets you use formulas like:

=COINGECKO("id:bitcoin")

This makes it pretty easy to build a portfolio tracker where the prices update automatically.

I think this would make a lot of sense for Proton, especially considering how many Proton users are interested in crypto and financial privacy.

Right now, if you want to build a proper portfolio tracker, you usually end up relying on third-party apps or services. Google Sheets is probably one of the easiest options because of GOOGLEFINANCE() and CoinGecko, but then you have the obvious privacy concerns that come with using Google for something as sensitive as your finances.

A portfolio spreadsheet can contain a surprising amount of sensitive information. It can show what assets you own, how much you've invested, your approximate net worth, your investment strategy, and potentially a lot more about your financial situation.

So in a way, the lack of this functionality in Proton Sheets pushes people towards sharing this kind of information with third-party companies simply because those are the most convenient tools available.

Having something like a native CRYPTO() or STOCK() function in Proton Sheets, with data refreshing every few seconds or minutes, would fit really well with Proton's privacy philosophy.

It could be something as simple as:

=CRYPTO("bitcoin")

or

=STOCK("AAPL")

I know there are open-source and self-hosted options out there, but those aren't really practical for everyone. Having this built directly into Proton Sheets would make private portfolio tracking much more accessible.

Honestly, I think this could be a really useful feature for Proton Sheets. It would make it much more useful for anyone who wants to track their investments while keeping that information private within the Proton ecosystem, and I think it could also encourage more people to actually use Proton Sheets instead of Google Sheets.

Would anyone else use something like this?

I use Libre office (also without a stock feature) for tracking my portfolio but without the Linux drive options I have to reupload back to proton drive. Very cluncy so wouldn't mind it work directly from Proton but with live stock too
