Tax records are personal. Here is exactly how yours are handled.
You export the CSV. We never ask for bank credentials.
Payments run through Stripe. We never see a card number.
Row-level security, enforced by Postgres, not by app code.
TLS on every request, AES-256 on every stored row.
Receipts and statements are private. Raw CSVs auto-delete at 90 days.
Categorisation uses Anthropic’s API, which by policy never trains on it.
Data on Supabase (Singapore) · hosting on Netlify · payments by Stripe — between them ISO 27001, SOC 2 Type 2 and PCI DSS Level 1.

“I built SaaSy Tax because tax was always a year-end scramble — a year of receipts and a weekend I’d never get back. It turns out the fix isn’t working harder in April. It’s five minutes a week, all year.”
