TNO (Trust No One)
A plain-language explanation of what “Trust No One” means inside Solid Invoice — and why it matters for your business records.
Security Explainer
What TNO means
TNO is a design goal: Solid Invoice is built to minimize who must be trusted with your business information.
In practice, that means your invoices, clients, and records are stored locally in the app’s sandboxed storage and protected by Apple platform security. Solid Invoice does not run a server that receives your invoice/client document contents.
Key idea: Solid Invoice is designed so your document contents are not sent to a Solid Invoice-controlled backend service.
Why it matters
Less exposure: fewer places your document contents can end up.
Ownership: your invoices and client records stay with you — you choose if/when to share or export.
Clarity: security is not just a statement; it’s a set of product choices (local-first, explicit exports, and optional sync behavior).
How it shows up in Solid Invoice
Local-first protection: data is stored locally and protected by Apple platform security (see Encrypted by Default).
Sync (when enabled): if you enable iCloud Sync, Solid Invoice encrypts sensitive data before it leaves your device (see Pre-egress Encryption).
Exports: exporting creates a copy outside the app’s protected storage, so Solid Invoice treats it as a deliberate action and asks you to confirm first (see Privacy-Aware Exports).
