## Description

Simple app to sync and combine your calendars locally on your device <b>without sending your data to external servers</b> or tracking software.<br><br>Merge events from Google Calendar, Outlook or any calendar account on your device into a single calendar: block time across accounts, avoid double bookings and keep your real availability up to date everywhere. All the synchronization happens 100% on your device.<br><br><b>Functionalities:</b><br>- Sync events between the calendar accounts already on your device (Google, Outlook, Exchange and more).<br>- Sync Center: pick multiple source calendars and one target calendar.<br>- Choose which properties to copy: title, description, location, time and recurrence.<br>- Sync range from 7 up to 30 days into the future.<br>- Custom title prefix for synced events (e.g. [SYNC]).<br>- Visibility override: keep source, default, private or public.<br>- Availability override: keep source, busy or free.<br>- Automatic background sync: set it once and stay updated forever.*<br>- Manage your active syncs: pause, resume or delete them at any time (optionally removing the events they created).<br>- Sync Now: trigger a manual sync with one tap.<br>- Browse your accounts, calendars and events without leaving the app.<br>- Simple Material 3 UI with light and dark theme.<br>- Optimized for phones, tablets and big screens (dual-pane view).<br>- Available in English and Spanish.<br>- <strong>YOUR CALENDAR DATA NEVER LEAVES YOUR DEVICE</strong><br><br><b>Usage:</b><br>- When you keep separate work and personal calendars and want your real availability visible in both.<br>- When you want to avoid double bookings between Google Calendar and Outlook.<br>- When you need one unified schedule without handing your calendars to a third-party service.<br><br><b>Privacy:</b><br>The INTERNET permission is used <b>only to validate your subscription with Google Play</b>. We do not send or collect any data on external services or servers: the sync runs locally through the Android calendar system, and your existing providers (Google, Outlook…) keep syncing your calendars with their servers as usual.<br><br>Tested on Android from 9 to 17 devices.
