Privacy Policy

Last updated: March 10, 2026

mylittlechart is designed with privacy first. We believe your data belongs to you.

What We Collect

Telemetry (opt-in): When enabled, we collect anonymous usage data to improve the application:

• A random device ID (not linked to your identity)
• Application version and platform (Windows/macOS/Linux)
• Session uptime

That's it. No personal information, no browsing history, no trading data.

Cookies

We use a single essential cookie to maintain your login session:

• session_id — A secure, HttpOnly cookie set when you log in via OAuth (GitHub, Discord, Google, X/Twitter, or Telegram). It expires after 24 hours and is used solely to keep you authenticated. We do not use this cookie for tracking or advertising.

We do not use any third-party cookies, tracking cookies, or analytics cookies.

What We Don't Collect

• No tracking cookies, analytics cookies, or advertising cookies
• No tracking pixels or analytics scripts
• No personal information (name, email, IP address)
• No trading data, positions, or balances
• No API keys or credentials

Where Data Is Stored

All your trading data, chart layouts, presets, watchlists, and settings are stored locally on your device. We never have access to this data.

Telemetry data, when enabled, is sent to our server (mylittlechart.org) and stored in aggregate form without any personally identifiable information.

Third-Party Services

We use Cloudflare for CDN and DDoS protection. Cloudflare may process connection metadata (IP addresses) according to their own privacy policy.

We do not use Google Analytics, Facebook Pixel, or any other tracking service.
