Proton Calendar

Pros

  • Event metadata is designed for zero-access encryption on Proton’s infrastructure
  • No ads or third-party trackers in the product’s privacy positioning
  • Same Proton Account ties calendar, mail, VPN, drive, and pass for one subscription story
  • Web plus iOS and Android clients cover typical mobile-and-browser workflows
  • Swiss jurisdiction and open-audit culture matter for security-sensitive teams

Cons

  • Feature depth and polish still trail Google Calendar for power schedulers
  • Store reviews cite sync latency, missing niceties, or occasional logout bugs
  • Deep Google Workspace or Microsoft org cal coexistence is not the primary design center
  • Native desktop clients are not the headline—browser access carries most laptop use
  • Meaningful calendar limits on the free tier push heavier users toward paid bundles

TickTick

Pros

  • Calendar, lists, habits, Pomodoro, and reminders ship in one bundle
  • Tomato timer plus stats cover focus ritual without another app
  • Lunar tabs cover Asia-first calendar quirks power users expect
  • Paid tier undercuts Todoist premium for similar breadth
  • Voice entry handles short captures while driving

Cons

  • UI density reads busy next to Things 3 minimalism
  • Natural-language date parsing trails Todoist’s headline feature
  • Privacy threads resurface whenever cloud-first vendors hiccup
  • Bare-metal markdown fans still export elsewhere
