I think someone installed stalkerware on my phone. What should I do?

Reviewed answer

Plan for safety before removing software or changing settings.

Use a device the person cannot access to seek help from a domestic-abuse advocate or trusted support person.
Record concerning incidents and preserve evidence safely. Removing software may alert the person monitoring you.
With a safety plan, arrange secure account changes and device recovery. A replacement or reset may be needed, but timing matters.

Get help if

Threats, coercion, or monitoring escalate. For immediate danger, contact local emergency services.
