Your memories,belong only to you.
Luban Lock is an ecosystem of privacy tools built on local-first encryption. We believe real privacy shouldn't have to be trusted — it should be enforced by code.
For every piece ofsensitivedata,
a workspace of its own.
Every product follows the same technical principles, focused on a different privacy scenario. Pick the one you need — or take them all.
100% offline · AES-256 · Zero cloud. Local-first encryption for your sensitive data.
AI-powered · Subscription-based. Creative and productivity apps.
No matter which product you choose,
they all follow the sametechnical principles.
These aren't marketing slogans. They are engineering constraints written into every line of code.
Zero cloud sync
Your data is never uploaded to any server. Your device is the only trusted computing environment.
Local encryption
All data is encrypted on-device with AES-256. Your master key never leaves the device.
Offline first
Full functionality works without a network. Connectivity is an optional enhancement, not a prerequisite.
Zero telemetry
We collect no usage data, no analytics, no event tracking. Privacy is not a feature — it is the baseline.
Auditable code
Our cryptographic core has been audited by independent third-party security firms. Reports are public.
Ethical by design
We sell no data, run no ads, and will never trade your privacy for growth.
If the day ever comes that we are forced to break any of these principles, we pledge to open-source everything and shut down — first.
