What It Is

CalUnity is a unified calendar app for people who use Google Calendar, Microsoft Outlook/365, Apple iCloud Calendar, and CalDAV at the same time. It offers iOS, Android, and Web apps. Its core goal is not to copy events into a new calendar, but to let users view schedules from different sources in one interface while keeping events in their original accounts.

Key Features

The product emphasizes an “Any Login” experience: users can sign in or connect via Google, Microsoft, Apple, or CalDAV, and the system automatically detects and loads the relevant calendars. Its AI assistant supports natural-language calendar actions and queries, such as creating a lunch appointment, checking the week’s schedule, analyzing time distribution, and detecting overlapping meetings or tight gaps between events. Notably, the AI does not modify calendars without user confirmation, and write access requires explicit authorization.

Privacy and Security

CalUnity’s main differentiator is its privacy-focused design: it is read-only by default, does not copy or propagate events across accounts, and does not generate duplicate events. Data is encrypted in transit via HTTPS, encrypted at rest in the database, and tokens are stored in encrypted form. The official website clearly states that it does not sell data, share data with advertisers, or use data for advertising profiles. Users can revoke connected account permissions with one click, and deleting an account removes the associated data. However, the text does not disclose formal compliance certifications such as SOC 2, ISO 27001, or GDPR.

Pricing and Business Model

The main website copy says the service is completely free, free forever, and requires no credit card, with the AI assistant, multi-provider sync, and unified view all included for free. However, the terms of service also mention both free and paid subscription plans, while specific paid features and pricing do not appear in the scraped content. Based on current information, the free tier appears to have a very low barrier to entry, but the long-term business model remains uncertain.

Pros, Cons, and Who It’s For

Its strengths are support for major calendar providers and CalDAV, availability across iOS, Android, and Web, and the fact that it avoids creating “busy block” clutter through cross-calendar syncing. Its weaknesses are that the product is only publicly launching in 2026, and there is limited information on enterprise permissions, admin controls, APIs, audit features, and compliance. It is better suited to individuals with multiple accounts, freelancers, cross-platform professionals, and users who want a unified view of work and personal calendars without copying data.

Access from China

The scraped text does not provide information on network accessibility in mainland China, app store availability by region, or supported payment methods, so its China access status is unknown. For similar alternatives in China, users may look at Outlook, Google Calendar, Apple Calendar, as well as schedule-management tools such as Morgen, Fantastical, OneCal, and Notion Calendar, though their ecosystems and access conditions vary.
