Private, offline Crypto Tax Calculator: Private, offline crypto tax calculator for US & Canada

I started building this because something about crypto tax software never sat right with me: to calculate your taxes, you have to upload your entire transaction history — every buy, sell, transfer, wallet address — to someone else's server. That's a massive amount of financial data handed to a third party, just to do math that could run on your own machine. So I built a tool that does exactly that. PrivateACB runs entirely on your desktop. No cloud, no account creation. Your data stays on your computer, encrypted with AES-256. The other thing that bugged me was the subscription model. You only file taxes once a year — why pay monthly? PrivateACB is a one-time $39 purchase. It started as a Canadian ACB (Adjusted Cost Base) calculator, but I've since expanded it to fully support US tax reporting too — FIFO/LIFO/HIFO, wash sale detection, Form 8949, Schedule D — including the new account-by-account basis tracking rules (T.D. 10000) that kicked in for 2025. Some highlights: - 12 tax reports (PDF + CSV), CPA-ready - Handles 100K+ transactions - CSV import from 10+ exchanges - Superficial loss (CA) and wash sale (US) detection - 30-day free trial, full features, no credit card I'd love to hear your feedback — especially from anyone who's dealt with the headache of crypto taxes. What's worked, what hasn't, what would you want in a tool like this?
