Show HN: Collaborative money tracker, E2E encryption, MCP (finance.rivaire.pro)

Hi HN, I'm Andrei. I built a money tracker for myself with everything I ever wanted from one.

What was important for me is wallets in different currencies (I travel a lot), planning future payments, seeing what balances would look like at certain date in the future and having external API and MCP.

I had plans of maybe making it public one day so I decided to encrypt amounts and balances to stand out from gazillion of other trackers, then I kept adding more stuff like semantic search, charts, shared wallets for collaboration, passkey-only sign in and so on.

It's a web app, I use it as PWA and it works fine for now. Native mobile apps are worth making only if there is demand, so current stack is Nextjs, Hono, Postgres, a VPS and Cloudflare.

I'd love feedback, especially on encryption and collaboration part and what would make you switch from your current tracker.
