Support

Lymi is free to use, and anyone can create an account. Email hello@lymi.app for help. The notes below solve the most common sign-in and connection problems.

Last updated 24 October 2026

Contact Lymi

Email hello@lymi.app. If the problem involves an account, write from the email address you use to sign in. Include what you were trying to do, what happened, and the browser or connected app you were using.

Do not send passwords, API keys, OAuth tokens, private lesson text or a full export unless we specifically ask for a safe, limited example. A screenshot should hide private card content and account details that are not needed to explain the problem.

Sign-in help

Anyone can create a Lymi account: continue with Google, or use an email address and a password. There is no invitation, no waiting list and nothing to pay.

  1. Open Lymi sign-in and continue with Google, or sign up with your email address.
  2. If Google signs you into the wrong account, sign out of Lymi and start again with the account you meant to use.
  3. If sign-in returns to the wrong page, start again from the Lymi page you meant to open.
  4. If the problem continues, send us the exact message and the time it happened. Do not send the callback URL if it contains a code or token.

Connected-app help

  1. In Lymi Settings, confirm the app appears under Connected apps and has the permission you intended.
  2. If permissions are wrong, disconnect it, then connect again and choose read-only or read-and-write on the consent screen.
  3. If you do not recognize a connected app, disconnect it immediately and contact us.

See the MCP overview for how permissions work and the setup guides for Claude and ChatGPT and Codex.

API help

  1. Send the key in the x-api-key header, never in a URL.
  2. Check that the key still exists in Settings and has the scope the request needs.
  3. A 401 usually means the key is missing, wrong or revoked. A 403 means the key does not have permission for that action.
  4. If a key may have leaked, revoke it and create a new one before contacting support.

Use the authentication guide and API reference for request details.

MCP connection help

  1. Use https://my.lymi.app/mcp as the server URL.
  2. Complete Google sign-in and the Lymi consent screen in the browser window that opens.
  3. If the client says registration or authorization failed, check its Lymi setup guide and remove any older Lymi connection before adding it again.
  4. Send support the client name, the exact error text and the time it occurred. Never send its token.

Access, export, correction or deletion

Export your library or delete your account in Settings on the web or You on the phone. You can edit cards and settings in Lymi. For other data requests, or to delete a publisher account, write to hello@lymi.app. We may ask you to verify your identity before acting. The privacy policy explains what deletion erases and what shared content remains.

Security reports

If you believe you found a security issue, email hello@lymi.app with a concise description and safe reproduction steps. Do not access another person’s data or include live credentials.
