Multiple external sources, configurable sync direction, and secure encrypted credential storage are all built in.\n\n---\n\n## Features\n\n- **Bidirectional sync** - changes made on either side are reflected on the other\n- **Multiple configurations** - connect to as many external CalDAV sources as you need\n- **Sync direction control** - bidirectional, external → Nextcloud only, or Nextcloud → external only\n- **Conflict resolution** - choose between \"update with newer\", \"skip\", or \"keep both\"\n- **Content-based duplicate detection** - matches events by title to avoid duplicates\n- **Scheduled sync** - runs automatically every 30 minutes in the background\n- **Manual sync** - trigger a full sync with one click\n- **Sync history** - view a log of recent sync runs with created/updated/deleted counts\n- **Secure credentials** - passwords encrypted with Nextcloud's built-in `ICrypto` before storage\n- **Auto-refresh** - configurable live status updates (1, 5, 10, 15 min, or custom)\n- **Languages** - English 🇬🇧 · German 🇩🇪\n\n---\n\n## Requirements\n\n| Dependency | Version |\n|---|---|\n| Nextcloud | 20 – 33 |\n| PHP | 8.0+ |\n\n---\n\n## Installation\n\n### From source (manual)\n\n1. Clone or download this repository into your Nextcloud `custom_apps/` directory:\n   ```bash\n   cd /path/to/nextcloud/custom_apps\n   git clone https://github.com/markusbegerow/nextcloud-calendar-sync calendar-sync\n   ```\n2. Enable the app in Nextcloud:\n   ```bash\n   php occ app:enable calendar-sync\n   ```\n3. Navigate to the **Sync** entry in the Nextcloud top navigation bar.\n\n---\n\n## Usage\n\n1. Click **Add Configuration** to create a connection to an external CalDAV server.\n2. Fill in the CalDAV server URL, username, and password. Use **Test Connection** to verify.\n3. Choose a sync direction and how to handle duplicate events.\n4. Enable the configuration and click **Sync Now** to run the first sync manually.\n5. Background sync runs every 30 minutes automatically - check **Recent Sync History** for results.\n\n### CalDAV URL examples\n\n| Provider | URL format |\n|---|---|\n| Nextcloud | `https://cloud.example.com/remote.php/dav/calendars/user/calendar-name/` |\n| Generic CalDAV | `https://example.com/dav/calendars/user/default/` |\n\n---\n\n## Security\n\n- Passwords are encrypted with Nextcloud's `ICrypto` service before being written to the database. They are never logged or stored in plain text.\n- All requests from the background job run within the Nextcloud security context of the owning user.\n\n---\n\n## License\n\n[GPL v3](https://www.gnu.org/licenses/gpl-3.0.html) © [Markus Begerow](https://markus-begerow.de/linktree)\n\n---\n\n## 🙋‍♂️ Get Involved\n\nIf you encounter any issues or have questions:\n- 🐛 [Report bugs](https://github.com/markusbegerow/nextcloud-calendar-sync/issues)\n- 💡 [Request features](https://github.com/markusbegerow/nextcloud-calendar-sync/issues)\n- ⭐ Star the repo if you find it useful!\n\n## ☕ Support the Project\n\nIf you like this project, support further development with a repost or coffee:\n\n\u003ca href=\"https://www.linkedin.com/sharing/share-offsite/?url=https://github.com/MarkusBegerow/nextcloud-calendar-sync\" target=\"_blank\"\u003e \u003cimg src=\"https://img.shields.io/badge/💼-Share%20on%20LinkedIn-blue\" /\u003e \u003c/a\u003e\n\n[![Buy Me a Coffee](https://img.shields.io/badge/☕-Buy%20me%20a%20coffee-yellow)](https://paypal.me/MarkusBegerow)\n\n## 📬 Contact\n\n- 🧑‍💻 [Markus Begerow](https://linkedin.com/in/markusbegerow)\n- 💾 [GitHub](https://github.com/markusbegerow)\n- ✉️ [Twitter](https://x.com/markusbegerow)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmarkusbegerow%2Fnextcloud-calendar-sync","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmarkusbegerow%2Fnextcloud-calendar-sync","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmarkusbegerow%2Fnextcloud-calendar-sync/lists"}
