- Monitored plans can run on a fixed term. Check your agreement for the end date and any early-termination fee.

Cancelling a security or identity-protection subscription
Security subscriptions often auto-renew and monitored plans can sit on a fixed contract term, so it matters when the request reaches the provider and whether it covers every device or location.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
