Sapphic Angels

Sapphic Angels is an independent software publisher focused on building practical, open-source productivity tools, with its source code hosted publicly on GitHub under the chiriapp organization. The publisher's catalog centers on Chiri, a cross-platform task management application designed to work with the CalDAV protocol, an open standard widely used for calendar and task synchronization. Rather than locking users into a proprietary cloud service, Chiri connects to existing CalDAV-compatible servers, allowing individuals to manage their to-do lists, deadlines, and recurring tasks through backends they already control or trust, such as self-hosted servers or standards-based providers. This approach places the software in the broader category of personal productivity and task management tools, with particular relevance for users who value data ownership, privacy, and interoperability across devices and ecosystems. Because the application is cross-platform, it suits workflows where tasks must stay synchronized between desktop and mobile environments, making it useful for freelancers, remote workers, students, and anyone coordinating personal or professional responsibilities across multiple machines. Typical use cases include organizing daily checklists, tracking project milestones, and maintaining a unified view of tasks alongside calendar events stored on the same CalDAV server. As an open-source project, the software also appeals to technically inclined users who prefer transparent, community-auditable codebases and the ability to inspect, modify, or contribute to the tools they depend on. Overall, Sapphic Angels represents a small, focused publishing effort whose product range emphasizes open standards, cross-device compatibility, and user autonomy over task data, offering an alternative to closed, subscription-based task managers for people who want dependable synchronization without surrendering control of their information.
