ChronoFlo Calendar has no write-up on Specifiction yet; its figures are above.

PragmaPlanner is web-based event-organisation software for building multi-track schedules for conferences, interview days and summits. Its solver searches scheduling combinations while considering attendee satisfaction and organiser constraints. You can assign speakers, record participant preferences, set room capacities and blocked times, and lock rooms or time slots. The software flags speaker overlaps, capacity problems and invalid placements. Attendee records can include descriptions, email addresses, availability and preferences, with assignments tracked in the project. CSV and ICS support data exchange, while customizable PDF exports create agendas. ICS import and export work with Google Calendar, Apple Calendar, Outlook and other digital calendar systems. Roomless sessions can run concurrently without room collisions, and hybrid schedules can combine physical and Roomless sessions. Projects are encrypted on the user's device before syncing or sharing, using AES-256-GCM, ECIES-based key exchange and HKDF-SHA-256. The maker says its servers cannot see schedules or participant data. The free plan costs nothing for up to 30 participants and 50 projects. Pro costs what you agree with the maker, billed plus taxes, with higher limits and priority support.
