Your data never leaves the browser. Here is the proof.
No backend, no accounts, no sync service. Every claim on this page is checkable against the running application — most of them in under two minutes.
Do not take our word for it — your browser ships the audit tool. Static application assets load once; after that, your workspace generates no outbound traffic you did not explicitly trigger.

| Article | Principle | Architectural answer |
|---|---|---|
| Art. 5(1)(c) | Data minimisation | The vendor processes zero customer workspace data. Minimisation is absolute — there is nothing on our side to minimise. |
| Art. 25 | Protection by design and by default | Zero egress is the design. There is no backend to misconfigure and no default sharing to switch off. |
| Art. 32 | Security of processing | The security boundary is your browser profile and device controls. Exported bundles support AES-256-GCM encryption; exports happen only on explicit user action. |
| Art. 17 | Right to erasure | Settings → Privacy & data erases every application key and downloads a deletion receipt (key list + SHA-256 of the removed payload). There is no server-side copy to chase. |
Compliance is a property of your process, not of any tool. This table documents the architectural facts the workbench contributes to that process.
A one-page architecture statement for vendor-risk reviews: processing summary, data location, the complete outbound-flow list and the GDPR mapping above — stamped with this browser's live storage figures. Generated locally, like everything else.
Encrypted workspace sync — end-to-end encrypted, so we still cannot read your data. It will ship when it meets that bar, not before.
SSO (OIDC) and self-hosted distribution — planned for the Enterprise tier; priced when they exist.
Until then, collaboration is snapshot export/import — deliberately boring, deliberately verifiable.
