Privacy-friendly calendar you can use without creating an account.

Android

Who is this for?

✓ Good for you if:

  • • You want fewer trackers and less account-linked data
  • • You care about privacy by default
  • • You want to avoid account creation

⚠ Think twice if:

  • • You need a hosted calendar service, account sync, or team scheduling built into the app
  • • You rely on advanced natural-language entry, conferencing integrations, or polished cross-platform clients
  • • Your Android calendar provider does not expose the calendars you need through system APIs

Key qualities

✓ Open source ✓ Encryption ✓ Low telemetry ✓ No account required

Overview

Etar Calendar is a calendar commonly used as a more privacy-respecting alternative to mainstream services.

Privacy notes:
- Aims to reduce tracking

, limit unnecessary data collection, and/or support stronger encryption.
- Your privacy still depends on your settings, device security, and (for hosted services) the operator.

Practical tip:
- Combine privacy-friendly software with strong passwords, 2FA, and regular updates for best results.
