❓ FREQUENTLY ASKED QUESTIONS
──────────────────────────────
Q: What happens if I forget my PIN?
A: You can recover access using your recovery passphrase set during
setup. Without it, documents cannot be recovered — this is
intentional for maximum security.

Q: Is my data backed up to Google Drive?
A: No. PrivateVault is fully offline. Nothing is uploaded anywhere.

Q: Can PrivateVault developers see my documents?
A: Absolutely not. We have no servers, no accounts, no access.
