❓ FAQ

Q: Is my financial data safe?
A: Yes. Each user's data is isolated by Supabase RLS — no user can access another's data. Files are stored in private buckets accessible only to the owning user. Sensitive fields are AES-256 encrypted.

Q: Can I use this without the AI features?
A: Yes — all dashboards work without AI keys. AI features (PDF parsing, chat advisor) require GEMINI_API_KEY and ANTHROPIC_API_KEY.

Q: How accurate is the PDF parsing?
A: Gemini 1.5 Pro is excellent at structured extraction. Accuracy is 90-95% for standard bank PDFs. You can always review and edit parsed transactions before confirming.

Q: Can I add manual transactions?
A: Yes — use the Expenses page's quick-add or the AI Ingest page for manual entry.
