About Vault-Budget

Vault-Budget is a zero-knowledge personal and professional finance manager, designed for people who want to take back control of their financial life without ever entrusting it to a third party.

Why Vault-Budget exists

Today's banking apps read your statements, score your behavior and resell your metadata. Cloud aggregators ask for your bank credentials to function. Open-source alternatives are often powerful but rarely deliver a premium multi-platform experience.

We wanted a tool as polished as a cloud app, but one you never need to trust. The result is Vault-Budget: locally encrypted, synced without disclosure, audited by design.

Our approach

Full zero-knowledge

AES-256-GCM, Argon2id, HMAC-SHA-256. Your data encrypted on your device, the server sees only noise.

Five native platforms

iOS, iPadOS, Android, macOS, Windows and Web. The same cryptographic promise, with experiences tuned for each OS.

Multi-currency and B2B

31 currencies, crypto tracking, isolated pro vaults with VAT, reconciliation, period closing and signed audit log.

Family vault

Multi-member encrypted sharing with roles, atomic key rotation, plausible deniability under duress.

Our team

Small distributed team based in France, made of cryptography engineers, product experts and personal and B2B finance specialists. We stay deliberately small to preserve product coherence.

Public roadmap

Documented public API for third-party integrations (read-only, encrypted)
Multi-vault mode for agencies and financial advisors
Independent audit published, cryptographic vectors revalidated yearly
More sector-specific B2B templates (construction, hospitality, creative freelance)
