Synthetic demonstration only. It uses fictional names, `.invalid` domains and a non-routable fictional telephone number.
Original content is excluded from reports by default. The print and downloaded-report choices are separate.
Privacy
Processing happens only in the browser. Invitation content is not uploaded, links are not visited, telephone numbers are not looked up, no AI model receives the invitation, no browser storage is used, and input is not placed in the URL. Original content is excluded from reports by default.
What calendar-invite scams look like
An unknown event can appear through an email invitation, shared calendar, imported ICS file, or a calendar setting that automatically adds invitations. Some fake calendar invitations use renewal, billing or refund claims to encourage an urgent call or click.
Inspect an ICS file safely
An ICS file is a plain-text calendar exchange file. It can contain event titles, organisers, attendees, locations, links, recurrence rules, alarms and attachments. Review it locally, do not open supplied links, and verify a claimed organisation through its independently located official website.
Google Calendar and Outlook risks
Calendar clients can present unexpected invitations prominently. That visibility does not validate the organiser, link or telephone number. Treat an Outlook or Google Calendar invitation like any unexpected message: verify the context before accepting, responding or acting.
How to verify independently
Do not use the link or phone number supplied in an unexpected invitation. Find the organisation's official site independently, sign in through a trusted bookmark or app, and contact the organiser through a known channel. Avoid replying if that would confirm your address is active.
Limitations
This deterministic calendar invite scam checker examines supported structure and wording only. It cannot prove who created an invitation, resolve a domain, look up a number, or guarantee that an invitation is genuine or fraudulent.
FAQ
Why did an unknown event appear in my calendar?
It may be an invitation, shared-calendar event, imported file, or an automatic-add setting. Review the source and your calendar settings before interacting.
Can this checker tell me an invitation is safe?
No. It reports supported concerns and limitations, not a definitive safety or fraud decision.
