Privacy Policy

Last updated: 27 October 2026

This policy explains what OhMyChart (“we”, “us”) collects when you use ohmychart.xyz, why, and the choices you have.

Using OhMyChart as a guest

You can use the chart without an account. Guest drawings and indicators are kept only in your browser’s session storage for the current tab and are deleted when you close it. We do not store guest charts on our servers. Display preferences such as theme, timezone and layout are kept in your browser’s local storage.

Information we collect when you sign in

  • Account details from Google or LINE: your name, email address (if the provider shares it) and profile picture. We never see your Google or LINE password.
  • Your content: workspaces, drawings, indicators, Pine Scripts, price alerts, alert channel settings (Discord or Slack webhook URLs, Telegram bot tokens and chat IDs, stored encrypted) and trade plans you create.
  • AI assistant conversations: messages you send to the assistant, the chart context attached to them and the replies.
  • Security and usage data: sign-in time, IP address, browser user agent and when you were last active.

How we use it

  • To sign you in and keep your workspaces and alerts in sync across devices.
  • To send the alerts you set up, including to the Discord, Telegram or Slack channels you add.
  • To answer your AI assistant questions.
  • To measure and improve the quality of the AI assistant and its trade plans, including by reviewing past conversations and how suggested plans played out against market data.
  • To keep the service secure and prevent abuse.

We do not sell your personal information and we do not show ads.

Who we share it with

  • Google and LINE, only to complete the sign-in you start.
  • OpenRouter and the AI model providers it routes to, which receive your assistant messages and chart context to generate replies.
  • Discord, Telegram and Slack, whichever you connect, which receive your alert messages.
  • Stripe, which processes Pro subscription payments. Stripe collects your card details directly; we only store your Stripe customer ID and subscription status.
  • Our hosting provider, which stores the service’s data on our behalf.
  • Our analytics provider, which receives the aggregated usage events described below.

Analytics

We use privacy-friendly, cookieless analytics to count page views and a few product events, such as opening the chart, starting sign-in and saving a guest chart. These statistics are aggregated, do not include your drawings or messages, and are not used to build a profile of you or to show ads.

Cookies

We use a secure, HTTP-only cookie to keep you signed in and a small cookie that remembers your last timeframe. We do not use advertising or third-party tracking cookies.

Keeping and deleting your data

We keep account data while your account is active. To delete your account and everything linked to it, email us at [email protected] from the address on your account. You can also ask for a copy of your data or for corrections.

Children

OhMyChart is not intended for anyone under 18.

Changes

If we make material changes we will update the date above and, where appropriate, notify signed-in users.
