Contact support
Email info@cardtoclose.com from your work email. Include your organisation, app version, device and operating-system version, approximate time of the problem, and the steps that caused it.
Sign-in and security
CardToClose mobile is for authorised users with an existing business account. For a forgotten password or lost authenticator, contact your organisation's Account admin first. Never send a password, authenticator code, recovery code or session token to support.
Capture and sync
Offline work stays queued on the phone until a connection is available. Open Profile > Diagnostics to check the app version, server health and queued-change count, then copy the sanitised diagnostic bundle if support asks for it. The bundle excludes tokens, contacts and message content.
Privacy and account deletion
Read the privacy policy or follow the account deletion process. Clearing the local cache removes this account's local data from the phone but does not delete data that already synchronised.
