Local encrypted files
Encrypted workspace and backup formats designed for the Windows app.
Our design separates user identity, licensing and business data. Local-only operation does not depend on putting customers' invoices on a remote web server.
These are security goals and features subject to release tests, not a guarantee against every threat.
Encrypted workspace and backup formats designed for the Windows app.
Role-based application access for local users; unrestricted OS administrators remain a separate trusted-device risk.
Future sign-in manages identity and entitlements; it must not silently sync business data.
Planned cryptographically signed licence file, verifiable without contacting a server.
Optional TOTP codes, compatible with authenticator apps, plus recovery codes and session controls.
Signed updates, recovery drills, testing and clear export rights are part of the release acceptance process.
No software can promise 100% security. Local data still requires secure Windows accounts, device updates, backups and sensible access controls. Cloud syncing and HMRC filing are not available in this public pre-launch site.
