Security & Privacy

Your data is yours.
Period.

memrynote is local-first, end-to-end encrypted, and open source. We built it for people who take ownership of their data seriously.

We cannot see your notes, even if compelled. The math guarantees it.

Standard Markdown on your disk. No proprietary format, no lock-in.

Sync accounts manage billing and devices. Vault keys stay on your devices.

How we protect your data

Six layers of privacy, from storage to sync.

Your notes are plain Markdown files stored in a folder you choose. No proprietary database, no vendor lock-in.

When you sync, every byte is encrypted before it leaves your device. We cannot read your data. Nobody can.

We collect anonymous usage analytics to improve the app. That is it. Your content never leaves your device.

AI is optional and can be turned on or off. With a local model, your notes are never sent to OpenAI, Google, or anyone else.

Paid multi-device sync uses CRDTs for conflict-free merging. Devices approve each other with QR codes, and vault keys stay off the server.

memrynote will be fully open source. Audit the code, verify our claims, build on top of it.
