About this app

Arpass is a next-generation password manager and file vault built so your data stays forever.

Highlights

■ Permanence — Stored on Arweave, a decentralized blockchain storage network. Even if Arpass shuts down, your data stays on the network.

■ Zero-knowledge encryption — All encryption happens in the client (app). A 2-of-3 scheme (Master password × Passkey × Recovery Secret) means we can never see your contents.

■ Autofill — Fill your saved passwords directly into other apps' and websites' login screens.

■ No monthly fee — no subscription. Reading and copying are always free. Only saves add about $0.02 to your usage, paid after use.

■ Receipt & file storage — Store not only passwords but also receipts, invoices, and contract PDFs or images, all encrypted.

■ OCR auto-entry — Automatically extract date, amount, and payee from a receipt image with AI. Bring your own OpenAI API key (BYO-key).

■ Built for bookkeeping — Searchable by date/amount/payee, an append-only audit trail for edits and deletions, and CSV export — designed to meet Japan's Electronic Bookkeeping Act (National Tax Agency) requirements.

Who it's for

・Anyone worried about what happens to their data if the password service they use shuts down
・People who find password-manager subscriptions (¥5,000+/year) too expensive
・Sole proprietors and SMBs who want to digitize receipts and streamline accounting
・Anyone who values data sovereignty and wants a service that cannot read their contents
・Users with multiple devices who want robust management with Passkey + Recovery

Security

・2-of-3: Master password × Passkey × Recovery Secret (with a hardware key such as YubiKey, you can unlock without a master password)
・Argon2id master-password protection (resistant to GPU/ASIC attacks)
・AES-256-GCM vault encryption
・WebAuthn / Passkey (FIDO2) required
・3-tier KEK (Key Encryption Key) architecture
・Only encrypted blobs live on Arweave; we hold no personal data

Pricing

・Free trial: up to 4 saves (create your drive + passwords + one file)
・One-time registration: about $2 (no monthly fee afterwards)
・Then pay only for what you use, after use: roughly $0.02 per save at the day's rate; files under 100 KiB are free
・Settle in-app anytime in small increments

Privacy

Arpass uses a zero-knowledge architecture; we cannot view the contents of your passwords or files. See arpass.io/privacy.html.
