The Idea

I would love to see Proton Calendar evolve into a unified productivity hub by integrating a native task and project management layer — think the best of Microsoft To Do and Microsoft Planner, but built with the privacy-first DNA that makes Proton what it is.

What I Am Proposing

A task management module embedded directly inside Proton Calendar that allows users to:

Create and assign tasks with due dates, priorities, and labels — visible alongside calendar events in a single, unified view.

Organise tasks into project boards — simple Kanban-style columns (To Do / In Progress / Done) for teams or personal workflows.

Track deadlines and milestones without leaving the calendar environment — no more context-switching between three different tools.

Set recurring tasks and receive reminders that align with existing calendar notifications.

Share task boards with collaborators within the Proton ecosystem, with granular permission controls.

Why This Matters

Right now, managing deadlines across tools is fragmented. Calendar events live in one place, tasks in another, and project milestones in yet another. For professionals managing complex, deadline-driven workflows — such as regulatory compliance cycles, multi-party projects, or recurring reporting obligations — this fragmentation creates real risk: missed deadlines, duplicated effort, and unnecessary context-switching.

Proton already owns the calendar real estate. Tasks are the natural next layer. The combination would make Proton Calendar a serious, privacy-respecting alternative to the Microsoft 365 productivity stack — without surrendering data to advertising-driven ecosystems.

The Ask

This does not need to be a full project management suite on day one. A phased rollout could work well:

Phase 1: Personal tasks with due dates, visible in calendar view.

Phase 2: Task lists / labels and recurring task support.

Phase 3: Shared boards and milestone tracking for teams.

Final Thought

Proton has already proven that privacy and productivity are not mutually exclusive. Adding a robust task layer to Proton Calendar would be the next logical step in making the full switch away from Big Tech ecosystems a realistic option for professionals and organisations that care about where their data lives.

Would love to hear whether others in the community share this need — and whether the Proton team has any plans in this direction.
