  --start "2026-02-10T10:00" \
  --end "2026-02-10T10:30" \

Supported Providers

Google Calendar Setup

Google requires OAuth2. Before running caldav-cli account add:

1. Go to https://console.cloud.google.com/
2. Create a project, enable CalDAV API
3. Create OAuth client ID (Desktop app type)
4. Note the Client ID and Client Secret

The wizard will ask for these, then open a browser for authorization. The refresh token is stored securely in the OS keychain.

Data Storage

• Passwords, OAuth2 refresh tokens, and OAuth2 client credentials (Client ID, Client Secret, Token URL): OS keychain (macOS Keychain, Linux libsecret, Windows Credential Vault) via @napi-rs/keyring. Never written to disk in plaintext.
• Account metadata (name, provider ID, username, server URL): ~/.config/caldav-cli/config.json (file permissions 0600).

No secrets are stored on disk. Existing installations that stored OAuth2 client credentials in config.json are automatically migrated to the keychain on first run.
