Delete Your Account

What gets deleted

• Your authentication record (sign-in credentials, OAuth links, session tokens).
• Your SIGBUILD user profile (name, profile photo, role assignments, certifications mirrored to our companion app Sigmark).
• Your project memberships — you'll no longer appear as an active project member.
• Your interface preferences and locally stored offline data (cleared on next app open).

What we have to keep

SIGBUILD is the official record of who did what during a railway signalling project. The work you have already attested to — test logs, shift reports, issues, audit events — forms part of a regulated evidence trail that the rail operator and the relevant safety regulator are entitled to retain. We are unable to delete those entries on request.

Specifically, we keep:

• Audit-trail events you generated, including the identity snapshot recorded at the time you took the action (name, role, certification status).
• Test logs, shift reports, issues, and other project contributions, frozen against the project they were filed under.
• Records of project sign-ins, sign-offs, and approvals that affect the integrity of the project's evidence chain.

Where possible we will pseudonymise these entries (replacing your contact details with a stable but non-identifying reference) once your account is deleted, but the historical attestations themselves remain.

How to request deletion

Send an email to integrations@lineside.app with the subject line "Account Deletion Request" from the email address associated with your SIGBUILD account.

How long it takes

We will acknowledge your request within 7 days and complete deletion of the items listed under "What gets deleted" within 60 days, in line with Google Play's data-deletion policy.

Alternative: In-app deletion
