Account and sign-in

You can sign in to the web app at app.quantral.com with email and password, Google, or Apple. If you are locked out, email us from the address on your account.

Subscription and billing

A subscription started on the web is managed from the account page in the web app. A subscription started in the iOS or Android app is billed by the App Store or Google Play, so you manage or cancel it in that store’s subscription settings. For billing questions, email us.

AI assistants

Quantral works inside ChatGPT, Claude and other AI assistants through our MCP server. Setup steps for each assistant are on the MCP page. The connection is read-only. If an assistant says it cannot reach Quantral, disconnect it in the assistant’s settings, connect again, and sign in with the account you use in the app.

Deleting your account

You can delete your account from the account screen in the app, or email us to do it for you. Details are in the privacy policy.
