Your files stay yours.
Mewndo keeps your files on your PC. The website stores only the few things you type when you sign up, so we can send you the app and tell you about it.
Last updated 12 October 2026
What we store when you sign up
- Your name and email address.
- Whether you want emails about new versions (off unless you tick the box).
- Which platform you asked for: Windows, or macOS when you join the macOS list.
- How you signed up: with your email, GitHub or Google.
- When you first signed up and when you last did.
- The country your request came from, as Cloudflare reports it. Not your IP address.
That’s all. It’s kept in a Cloudflare database that belongs to Mewndo, and we use it only to send you the download and, if you asked, emails about Mewndo. We never sell it or share it for advertising.
What we never store
- Passwords. There are none: your account is your email.
- GitHub or Google access. When you sign in with them, we ask only for your name and verified email address, read them once, and throw the access token away.
- Your files. The website never sees them.
What the app keeps
The Mewndo app keeps its save points, file versions and history in your app data folder on your PC. File contents and file names don’t leave your computer.
Optional cloud features, off until you turn them on. If you turn on Mewndo’s decision help (Clef) or voice, the details of the agent action being judged, or what you said, go to Mewndo’s gateway on Cloudflare to be answered. If you connect a cloud agent through Mewndo’s MCP server, its questions and your answers pass through the same gateway. None of this happens unless you switch it on in the app.
Deleting your account
Email [email protected] from the address you signed up with and ask us to delete it. We’ll remove everything listed above and confirm by email. You can also ask us what we hold about you, or to correct it, the same way.
To stop update emails without deleting your account, reply to any update email or write to the same address.
Cookies
The site sets no tracking or advertising cookies. Signing in with GitHub or Google uses two short-lived cookies: one that protects the sign-in from forgery (gone after ten minutes), and one that shows your name on the download page once (gone after five minutes).
Changes
If this page changes, the date at the top changes too. If a change affects what we store, we’ll email people who signed up before it takes effect.
