You can delete your LineHQ sign-in yourself, from the app or the web dashboard. Closing a whole business account — releasing its numbers and ending billing — is a separate, deliberate step, and this page explains both.

Two different things

On a phone system these are not the same, and people are often surprised by the difference, so we spell it out before you do anything.

Deleting your sign-in removes you — your login, your access on every device, and any API tokens you created. The business account carries on for everyone else on the team.
Closing the business account ends the plan and gives up the phone numbers. That affects everyone on the account and cannot be undone once numbers are released, so we do it with you rather than behind a single button.

Delete your sign-in

In the LineHQ mobile app:

Open Settings.
Tap Delete account.
Read what is and is not removed, then enter your password to confirm.

On the web dashboard, the same option is in Profile.

Your sign-in stops working immediately. This cannot be undone — if you need access again, an owner on the account has to invite you back.

What deleting your sign-in removes

Your user account and password.
Your access to LineHQ on every device you were signed in on.
Any API tokens you created.
Any biometric or passkey credential registered to your login.

What it does not remove

These belong to the business account, not to your personal sign-in, and they stay with the business:

Phone numbers, and where calls to them are routed.
Call history, call recordings, voicemail and transcripts.
Text messages and receptionist message slips.
Billing records, invoices and the wallet balance.

Close a business account entirely

Because the numbers have to be dealt with first, this one goes through us. Numbers can be ported out to another provider if you want to keep them, or released if you do not — and a released UK number cannot be recovered, by us or by anyone else.

Email privacy@linehq.co.uk from the address on the account, or write to us using the details on our contact page, and say you want to close the account. We will confirm what will be deleted, sort out the numbers with you, and then remove the account. We aim to respond within a few working days, and to complete the deletion within 30 days of confirming it with you.

You do not need an active login to make this request — if you have already deleted your sign-in, or lost access, email us and we will verify you another way.

What we keep afterwards, and why

Deleting an account does not wipe everything instantly, because some records we are required to keep and others expire on their own schedule.

Call recordings, voicemail and transcripts are deleted on the retention window that applies to the account's plan, and are removed as part of closing an account.
Call records (who called, when, how long — not the audio) are kept for the account's call-history window, then deleted automatically.
Billing and tax records are kept for as long as UK law requires, which is currently six years. We cannot delete these on request, and no phone system can.
Fraud and abuse records may be kept where we need them to protect the network and other customers.

Backups are deleted on their own rotation, so a copy may persist there briefly after live data has gone.

Your other rights

Deletion is one of several rights you have under UK GDPR — you can also ask for a copy of your data, or ask us to correct it. Our Privacy Policy covers all of them, along with how to complain to the Information Commissioner's Office if you are not happy with how we have handled a request.
