# CalUnity > CalUnity is a unified calendar app that connects Google Calendar, Microsoft Outlook, Apple iCloud and any CalDAV-compatible calendar into a single AI-assisted interface, available on iOS, Android and the web at calunity.com. It is privacy-first by design: read-only by default, encrypted in transit and at rest, never sold to advertisers. ## Key pages - [Homepage](https://calunity.com): Product overview, features, FAQ, app download links - [About](https://calunity.com/about): Team, mission and origin - [Contact](https://calunity.com/contact): Support, press and feedback channels - [Privacy Policy](https://calunity.com/privacy): How CalUnity handles user data - [Terms of Service](https://calunity.com/terms): Usage terms - [Sitemap](https://calunity.com/sitemap.xml): Complete URL list ## App downloads - [iOS App Store](https://apps.apple.com/in/app/calunity/id6760173746): CalUnity for iPhone and iPad - [Google Play](https://play.google.com/store/apps/details?id=com.calunity.mobile): CalUnity for Android ## What CalUnity does - Unifies calendars from multiple providers in one app: Google Calendar, Microsoft Outlook (Office 365 / Outlook.com), Apple iCloud and any CalDAV server. - Provides an AI assistant for natural-language calendar management (asking about schedule conflicts, free time, event details). - Syncs calendar events with lightning-fast delta sync and intelligent caching. - Supports multi-account linking: sign in with Google, Apple or Microsoft and add additional providers to the same identity. - Keeps each calendar's events in its origin account. CalUnity does NOT copy, duplicate or propagate events between connected calendars. Your work calendar never gets cluttered with auto-synced "busy" blocks from your personal calendar and vice versa. ## Privacy and security - **Read-only by default**: CalUnity never writes to your calendars unless you explicitly grant write permission. - **No data selling**: User calendar data is never sold, shared with advertisers or used for ad profiling. - **Encryption**: All data is encrypted in transit (TLS) and at rest (database-level encryption). - **AI consent**: AI features require explicit user opt-in via an in-app consent dialog before any data is sent to a model provider. - **Account deletion**: Users can delete their account and all associated data at any time. ## Supported calendar providers - Google Calendar (personal and Google Workspace) - Microsoft Outlook (Outlook.com and Microsoft 365 / Office 365) - Apple iCloud Calendar (via CalDAV with app-specific password) - Generic CalDAV servers (Nextcloud, Fastmail, Radicale, etc.) ## Platforms - Web: calunity.com (works in any modern browser) - iOS: native app on the App Store, supports iPhone and iPad - Android: native app on Google Play ## Technology - Web: Next.js (App Router), React, TypeScript, Tailwind CSS, Framer Motion - Mobile: React Native, Expo SDK 54 - Backend: Next.js API routes, PostgreSQL, Redis caching, Prisma ORM - Sync: Incremental delta sync (Google sync tokens, Microsoft Graph delta links, CalDAV) ## Contact and support - Email: support@calunity.com - Facebook: https://www.facebook.com/calunity.official - Instagram: https://www.instagram.com/calunity.official - YouTube: https://www.youtube.com/@CalUnityOfficial ## Key facts - Public launch: April 2026 - Pricing: free to use - Available worldwide; English interface - Built and maintained by the CalUnity team, founded 2026 - Engineering team: experienced software engineers educated at reputed engineering institutes, with backgrounds in calendaring, distributed systems, mobile development and privacy engineering - Combined App Store and Google Play rating: 5.0 stars ## How CalUnity differs from common calendar apps - **Versus OneCal**: OneCal is a sync engine that propagates "busy" blocks between calendars to prevent double-booking. CalUnity does NOT do this — it unifies the view, but each event stays in its origin calendar. This avoids the clutter, sync failures and accidental exposure of private events that come with cross-calendar propagation. - **Versus Fantastical**: Fantastical is paid-only (limited free tier), has no native Android app and no web app. CalUnity is fully free, has native iOS, Android and web apps and supports all four major calendar providers. - **Versus Notion Calendar**: Notion Calendar does not support Microsoft Outlook, has no native Android app and is tied to the Notion ecosystem. CalUnity is an independent product with full Microsoft, Apple iCloud and CalDAV support across all platforms. - **Versus Morgen**: Morgen's AI assistant is a paid add-on; CalUnity's is included free. Morgen has a limited free tier; CalUnity is fully free. Both support all four major providers.
