## What is CalDelta?

CalDelta answers one question: what has changed in my calendar since I last looked?

Open it and you get a plain list of the events that have been added to or removed from your calendars — Google, iCloud, Exchange, work, anything your iPhone already syncs — grouped into the last 24 hours, the last 7 days and the last 30 days. Each row carries the full detail: title, date and time, location, notes, and which calendar it came from.

A once-a-day digest tells you when something has changed, and stays quiet when nothing has. You choose the time.

Clearing a row from the list never touches your calendar. Swipe one away, or use Select All to clear the lot — the events themselves are left exactly as they are.

Your calendar data never leaves your phone. CalDelta reads it on the device and keeps its own record there. Nothing is uploaded, there are no accounts, and there is no analytics.

• Every calendar your iPhone syncs, in one list
• Additions and removals, bucketed by when they happened
• Full event detail on every row
• A daily digest at a time you pick — only when something actually changed
• Swipe, multi-select or Select All to clear rows
• No account, no tracking, no calendar data off the device
