Questions & Answers
Frequently Asked Questions
Is Saphirium a monthly subscription or a one-time purchase?
Strictly a one-time purchase — zero monthly subscriptions, zero ads, and no hidden fees. Microsoft Store automatically displays the regional price in your local currency, with future updates included.
Does it work without a Google account or internet connection?
Yes! You can use Saphirium 100% locally on your PC without signing into any account. And if you connect Google and go offline, you can still add and edit events and tasks — the offline queue syncs everything automatically once your connection returns.
Can you see my calendar events or personal tasks?
Never. Saphirium has no developer backend servers, analytics, or trackers. Your PC communicates directly with official Google services over encrypted HTTPS, and authorization tokens are protected locally by Windows.
How do I pin it to my desktop wallpaper and hide it from the taskbar?
Place the widget anywhere on your screen and press Ctrl + L (or click the lock icon in the header) to lock its position and size. In Settings, you can hide it from the taskbar into the system tray and enable Launch at Startup.
Which cloud calendar services are supported for synchronization?
Cloud synchronization is purpose-built for fast, reliable sync with Google Calendar and Google Tasks, alongside full standalone Local PC storage. Meeting links for Microsoft Teams, Zoom, and Google Meet inside your events are detected automatically.
Does it work on Windows 10 and is it gentle on laptop battery?
Yes, it runs smoothly on both Windows 10 and Windows 11. Saphirium opens instantly from local cache, pauses background timers when your laptop sleeps, and stays lightweight all day.
