About
CalendarGuardian helps you review suspicious calendar invitations and understand the reasons behind a 0–100 risk score.
Scan selected calendars available on your device, review flagged invitations, approve legitimate invitations, manage trusted and blocked senders, and remove unwanted events. Scan results show completion information and counts. Calendar availability depends on the accounts and calendars configured on your device.
New invitation assessments require sign-in to your CalendarGuardian account and an internet connection. Details from the calendars you select are sent securely to the same CalendarGuardian service used by the website and Outlook add-in. Supported rules, decisions, connections and reports synchronize with your account. Optional email invitation scanning requires separate authorization; calendar permission does not grant mailbox access. Email scanning and email cleanup have separate permissions; cleanup runs only when separately authorized. Calendar cleanup depends on your settings and permissions; automatic cleanup acts only when enabled and applicable. CalendarGuardian does not guarantee that every unwanted invitation will be prevented or detected.
Calendar access is requested through Apple’s permission controls. You choose whether to grant access and which calendars to scan. Server processing, account data, email scanning, and purchase verification are described in the privacy policy.
Free to download. Paid protection is offered through an annual auto-renewing subscription. The App Store displays your localized price and any eligible introductory offer before purchase. A CalendarGuardian account is required to link a new in-app purchase. Subscriptions renew automatically unless canceled. Manage or cancel Apple subscriptions in Apple Account settings.
