Calendarchy — Privacy Policy

Last updated: March 10, 2026

What Calendarchy is

Calendarchy is an open-source terminal application that displays your calendar events. It runs entirely on your computer. There is no server, no backend, and no cloud component operated by us.

Data we access

When you connect your calendars, Calendarchy accesses:

• Your calendar event data (titles, times, locations, attendees, meeting links) from Google Calendar and/or iCloud Calendar

This data is used solely to display your events in the terminal interface and to perform actions you initiate (accepting or declining events, opening meeting links).

Data storage

All data stays on your machine:

• OAuth tokens are stored in ~/.config/calendarchy/tokens.json
• Cached events are stored in ~/.cache/calendarchy/events.json
• Configuration is stored in ~/.config/calendarchy/config.json

No data is transmitted to any server other than the Google Calendar API and Apple CalDAV servers required to fetch and update your events.

Data we do not collect

• We do not collect analytics or telemetry
• We do not track usage patterns
• We do not store any data on remote servers
• We do not share any data with third parties
• We do not use cookies

Google API usage

Calendarchy requests access to the calendar.events scope, which allows reading and writing calendar events. This is used to:

• Display your events
• Accept or decline event invitations on your behalf when you choose to

Calendarchy's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

iCloud usage

For iCloud Calendar access, Calendarchy connects to Apple's CalDAV servers using an app-specific password that you generate. This password is stored locally in your configuration file. We never see or transmit this password beyond Apple's servers.

Revoking access

You can revoke Calendarchy's access at any time:

• Google: Visit Google Account Permissions and remove Calendarchy
• iCloud: Revoke the app-specific password at appleid.apple.com
• Local data: Delete ~/.config/calendarchy/ and ~/.cache/calendarchy/

Children's privacy

Calendarchy is not directed at children under 13 and we do not knowingly collect data from children.

Changes to this policy

If this policy changes, the updated version will be posted here with a new date. Since Calendarchy has no server component, there is no way to notify you of changes other than through software updates.
