Bring your calendar and contacts into your notes.
Harang App is the shared identity behind two small, open-source Obsidian plugins — Harang Calendar and Harang Contacts. Both connect directly to your own CalDAV/CardDAV server or Google account and display your data inline in your notes. Everything runs locally on your device — there is no Harang App server in between.
Products
Harang Calendar
A CalDAV calendar viewer for Obsidian. Connect any CalDAV server — or Google Calendar — and
reference dates and events inline in your notes with a staged autocomplete trigger
({{hrcal:...}}). Currently read-only: it fetches and displays your events.
Two-way sync — creating and editing events from your notes — is planned for a future release.
Harang Contacts
A CardDAV address book viewer for Obsidian. Connect any CardDAV server — or your Google
Contacts — and reference people inline in your notes with a staged autocomplete trigger
({{hrcard:...}}). Currently read-only: it fetches and displays your contacts.
Two-way sync — creating and editing contacts from your notes — is planned for a future
release.
How your data is handled
- All data fetching happens directly between your device and your CalDAV/CardDAV server or Google's own servers — Harang App does not operate a backend, and your data never passes through any server we run.
- Sign-in credentials and Google account tokens are stored only on your device, using Obsidian's built-in secure storage. They are never transmitted anywhere except to Google's own token endpoint to refresh access.
- Fetched events and contacts are cached locally inside your Obsidian vault so notes render without a network round trip every time.
- Both plugins are fully open source — you can read every line of code that touches your data.
