# About Memento

Memento is a privacy-first workspace for your thoughts, credentials, and ideas. We believe your data belongs to you — not advertisers, not data brokers, not even us.

## Our Mission

We're building the workspace we always wanted — one where end-to-end encryption isn't an afterthought, where your notes are truly private, and where powerful features don't come at the cost of your privacy. Memento combines a rich Markdown editor, an encrypted vault, and smart link management into a single, cohesive platform.

## What We Stand For

### Privacy First

Zero-knowledge encryption: we can't read your notes, vault entries, prompts or attachments. Titles, tags and links aren't encrypted. See [Security](https://mementosite.me/security).

### Security by Design

XChaCha20-Poly1305 encryption, end-to-end encrypted sync, and device-level key management.

### Performance

Offline-first with instant local access. Your data is always available.

### User Owned

Your data, your keys, your choice. Export everything anytime.

### Open Development

Transparent about our practices, honest about our limitations.

### Accessible

Built for everyone — keyboard navigation, screen readers, and responsive design.

## What Memento is

-   Notes: a block editor with Markdown shortcuts, code in 37 languages, LaTeX, tables, templates and wiki-style links
-   Vault: passwords, cards, identities and secure notes, with each field value encrypted
-   Links: a bookmark library with automatic previews, collections and browser-bookmark import
-   Prompts: a library for the prompts you use with AI tools, with template variables

All four sync in real time across your browsers, work offline, and can be exported at any time.

## How we work

-   We publish what our servers can and can't read, including what isn't encrypted, on our Security page.
-   Changes are planned, implemented and then reviewed against the code, with Claude Code doing much of the implementation.
-   We haven't had a third-party security audit yet, and we say so.

## Where we are

Memento is built in Hyderabad, India. We're bootstrapped and in public beta.

## Built with Claude

Claude Code, Anthropic's agentic coding tool, writes much of Memento's codebase through agentic workflows.
