Google Calendar vs Proton Calendar: pros and cons
Google Calendar
Google Calendar is free, dependable, and woven into Gmail and Meet, with smart sharing controls and real-time sync across web, Android, and iOS. Task tools stay basic, there's no native desktop app, and some scheduling features sit behind paid Workspace plans. Overall, it's the obvious default for anyone already living in Google's ecosystem.
Pros
- Completely free for personal use, with no paywall on core scheduling features like sharing, reminders, and recurring events
- Automatic event creation from Gmail confirmations—flights, hotels, and reservations arrive as ready-made calendar entries
- One-click Google Meet links turn any event into a video meeting without third-party conferencing software
Cons
- No native Windows or macOS desktop app—desktop users are limited to the browser or third-party clients
- Task and reminder features are basic compared with dedicated to-do or project management tools
- Advanced options like appointment schedules and time insights require a paid Google Workspace plan
Proton Calendar
Proton Calendar encrypts every event detail end-to-end, including on the free tier, and invitations work with people outside Proton. Calendar sharing costs extra, ecosystem features trail mainstream rivals, and the pricing page hides actual prices. Overall, it's a strong privacy-first pick if confidentiality matters more than ecosystem polish.
Pros
- End-to-end encryption covers event contents on every plan, including the free tier — not a paid-only feature
- Swiss incorporation places data under strict Swiss privacy laws and a neutral jurisdiction, a genuine structural difference from US-based Big Tech calendars
- Send and receive invitations works with people outside Proton, so privacy does not come at the cost of coordinating with mainstream users
Cons
- Calendar sharing requires a paid plan (Mail Plus or Proton Unlimited) — it is not available on the free tier
- The free plan caps you at 1 GB of overall Proton storage and a single encrypted email address, which limits how far you can adopt the ecosystem without paying
- Feature depth lags established Big Tech calendars in areas like extensive third-party integrations and ecosystem conveniences, a trade-off of the privacy-first architecture
