Privacy Policy

Effective date: February 12, 2026 · Last updated: February 12, 2026

CH-UI ("we", "our", "us") is developed by Caio Ricciuti. This privacy policy explains how we handle data when you use CH-UI software.

What CH-UI Does NOT Collect

CH-UI is a self-hosted application. When you run CH-UI on your own infrastructure:

  • No telemetry is sent to us or any third party
  • No usage data leaves your server
  • No analytics are collected
  • No cookies are set by us (only session cookies for your own login)
  • Your queries, data, and database contents never leave your infrastructure

Data Stored Locally

CH-UI stores the following data in a local SQLite database on your server:

  • User sessions — login tokens for authenticated access
  • Saved queries — queries you choose to save
  • Dashboard configurations — layout and panel settings (Pro)
  • Scheduled jobs — query schedules you create (Pro)
  • Connection settings — ClickHouse connection details (encrypted)
  • License information — your license key if you activate Pro
  • Application settings — preferences and configuration

All data is stored in the SQLite file specified by database_path in your config (default: ./data/ch-ui.db). You have full control over this data.

Pro License Activation

When you activate a Pro license, the license file is stored locally in your database. No information is sent to external servers during activation — the license is validated offline using cryptographic signatures.

Cloud-Hosted Version

If you use our cloud-hosted version at cloud.ch-ui.com:

  • We store your account information (email, name) for authentication
  • We store your ClickHouse connection metadata (not your database contents)
  • We do not access, read, or store your ClickHouse data
  • Tunnel connections are end-to-end between your agent and your browser session

Third-Party Services

The self-hosted CH-UI binary does not communicate with any third-party services except:

  • Your ClickHouse server — as configured by you
  • OpenAI API — only if you configure the Brain AI feature (Pro) with your own API key

Data Deletion

Since all data is stored locally:

  • Delete the SQLite database file to remove all application data
  • Uninstall the binary to fully remove CH-UI
