On-Device — Encrypted by Default
From day one, Solid Invoice was designed to protect your business data and your client relationships.
- No collection, no storage — Solid Invoice never collects or stores user or client data. Period.
- Device-level encryption — your invoices, quotes, clients, expenses, and settings are stored locally and encrypted at rest. If a device is lost, stolen, or compromised, those encrypted files are useless to an attacker without your credentials.
- TNO sync with pre-egress encryption — if you enable iCloud sync, your data is encrypted before it leaves your device; even Apple only sees scrambled data.
- User responsibility & control — you decide what to export, when to share it, and how to store it. We provide the tools; you keep control.
