Partners often share a lot digitally: passwords typed in front of each other, a shared laptop, location sharing, a family cloud plan. After a breakup, or in a relationship where one person controls the other, that access can be misused to read messages, track location or take over accounts. Reviewing access carefully restores your privacy.

If you are in an abusive or controlling relationship, sudden changes such as blocking location sharing can alert the other person and may increase risk. Contact a domestic abuse support service for safety planning before making changes, and use a device the other person cannot access.

Where access hides

  • Passwords they know, or saved on shared devices.
  • Your email's recovery phone or email pointing to them.
  • Devices still signed in to your accounts.
  • Location sharing in maps, phone or family apps.
  • Family plans that share photos, purchases or location.
  • Cloud backups syncing your photos and messages.
  • Apps installed on your phone to monitor you.
  • Smart home devices and cameras.

A safe review, in order

  1. Email: new password, two-step verification, check recovery details, sign out all other sessions, check forwarding. See securing your email.
  2. Phone: new screen lock; review installed apps and device admin or accessibility permissions; check your phone's cloud account devices.
  3. Location sharing in maps, phone and family apps.
  4. Banking and payments: passwords, PINs, linked devices, joint account arrangements.
  5. Social media and messaging: active sessions, linked devices (such as WhatsApp linked devices).
  6. Shared plans and smart home devices.

Signs of monitoring software

  • The other person knows things they could not otherwise know.
  • Unfamiliar apps, or apps with accessibility or admin permissions.
  • Unusual battery drain or data use.

The FTC's guidance on stalkerware explains what to know. If you suspect monitoring, get specialist advice before removing it, as removal can alert the person who installed it.
