All secrets (webhooks, bot token, chat ID) are stored securely using VS Code's SecretStorage — they never go into your settings.json or source control.
Privacy & Security
No backend server: This extension does not operate any cloud service and does not relay your messages.
Direct delivery: Notifications are sent from your VS Code directly to Slack, Microsoft Teams, or Telegram via their official webhook/API endpoints.
Your credentials: You provide and control your own webhook URLs or bot tokens. The extension does not create, proxy, or manage provider accounts.
Local secure storage: Sensitive values are stored in VS Code SecretStorage and are never written to files in your workspace or settings.
