Privacy Policy

Last updated: May 13, 2026

Hora Calendar is a native macOS application for Google Calendar with optional Zoom integration. Your privacy matters, so below is exactly what we access and how we use it.

Data We Access

  • Google Calendar: events and calendars (read & write)
  • Google Other Contacts: names and emails (read only, for guest autocomplete)
  • Google account email address
  • Zoom account profile basics (user info needed to identify connected account)
  • Zoom meeting data for meetings created or managed from Hora (metadata such as meeting ID, join link, start link, passcode, schedule/status)

How We Use It

  • Display and manage your calendar events
  • Provide autocomplete suggestions when adding guests to events
  • Synchronize changes with Google Calendar
  • If you connect Zoom: create, update, read, and delete Zoom meetings when you choose Zoom as the conference provider
  • Show Zoom meeting details in the app UI (join URL, meeting ID, passcode) for your own events

Zoom OAuth Scopes and Purpose

For v1, Hora uses a minimal Zoom scope set required for meeting lifecycle only:

  • meeting:write:meeting: create Zoom meetings for events.
  • meeting:update:meeting: update meeting details when event title/time changes.
  • meeting:delete:meeting: delete/cancel Zoom meetings when events are removed.
  • meeting:read:meeting: read meeting metadata needed to render and sync meeting details.
  • user:read:user: read the authorized Zoom user profile to identify the connected Zoom account.

Hora does not request webinar scopes and does not use Zoom data for ad targeting, profiling, or model training.

Data Storage

  • App data is stored locally on your Mac using SwiftData
  • OAuth tokens are stored in the macOS Keychain
  • Hora does not operate a general-purpose backend that stores your calendar/meeting content
  • OAuth callback infrastructure may transiently process authorization flow parameters required to complete sign-in securely
  • This website uses Plausible Analytics, Google Analytics 4, and Google Ads conversion tracking as described below

Website Cookies & Advertising

The Hora Calendar macOS application does not set cookies or use advertising tracking. The marketing website at horacal.app uses a limited set of third-party technologies:

  • Posthog: Traffic analytics, error handling, edge cases.
  • Google Ads conversion tracking: when you arrive from a Google Ads click, Google's gtag.js may set first-party cookies (_gcl_au and related) to measure whether you later complete newsletter signup.
  • Google Analytics 4 (GA4): aggregate site usage measurement (pageviews, referrers, device type). Consent Mode v2 is enabled.

You can opt out of Google Ads personalization at adssettings.google.com, or block these cookies in your browser.

Data Protection

  • All communication with Google and Zoom APIs is encrypted in transit via HTTPS (TLS)
  • OAuth authentication tokens are stored in macOS Keychain (hardware-backed encryption, protected by your system login)
  • Local cached data remains inside the macOS app sandbox
  • Hora requests the minimum practical scopes required for enabled features
  • Hora does not sell personal data and does not share user data with data brokers
  • Hora does not use your calendar/Zoom data for advertising personalization

Data Sharing

  • We do not sell your data
  • We do not share your calendar or Zoom content with third parties, except API processors required to provide the service (Google and Zoom)
  • We do not use your app data for advertising or profiling
