Help with the HeliusOne terminal, the iPhone app, your plan and your account.

The Setup Guide walks through creating your account, linking a brokerage and adding an AI key, on the web terminal and the iPhone app.
You can subscribe and explore the terminal before you link a brokerage; the app offers the link again from any empty screen.
Some brokerages link with a single sign-in at the brokerage, with no API keys; others use developer keys you create at the broker. Where the brokerage offers both, you can link a paper (simulated) account, a live account, or both, and switch between them in Settings.
Other supported brokerages link with your own API keys; the Setup Guide has the steps for each one.
HeliusOne never holds your money or securities. Orders go to your own brokerage account, and your broker provides the brokerage and custody services.
AI analysis runs on your own API key from Anthropic, OpenAI or Google, and that provider bills you for its use. Add or change keys in the web terminal’s Settings or during setup on the iPhone app.
AI output is for information only and is not investment advice.
By default every order needs your approval: the app shows a confirmation before anything is sent, and Express Approval orders expire unplaced if you do not approve them.
Automated trading is available only with your consent and only through brokerages whose policies allow it (the terminal marks which of your linked brokerages qualify). Turn it on or off in Settings → Trading; turning it off withdraws your consent. See the Terms of Service and the Disclaimer.
An AI assistant you connect through the AI Assistant connector only sees and does what you allow in Settings, and you can revoke its access at any time.
Plans bought on heliusone.com are managed on your Account page, where you can change or cancel them.
Plans bought in the iPhone app are billed by Apple. Manage or cancel them in your iPhone’s Settings → your name → Subscriptions, and request App Store refunds at reportaproblem.apple.com.
A plan works everywhere you sign in to HeliusOne, wherever you bought it.
To report a message, long-press it in the iPhone app or right-click it in the web terminal and choose Report. To report or block a person, open their profile from their name or avatar.
Blocking hides that person’s messages, invites and notifications from you, and they are not told. You can unblock people from your own chat profile.
We review every report within 24 hours and remove content or accounts that break the Terms of Service. For anything urgent, email support@heliusone.com.
In the iPhone app, go to Settings → Delete account. On the web, email support@heliusone.com from the address on your account and we will delete it.
Deleting your account does not cancel an App Store subscription; cancel it in your iPhone’s subscription settings first.
To request a copy of your data or a correction, email support@heliusone.com. We respond within 30 days. Our Privacy Policy explains what we store and why.
If you believe you have found a security issue, email support@heliusone.com with the details. Please do not share it publicly until we have had a chance to fix it.
