Support requests are reviewed during normal United States business days.
Do not send passwords, API keys, recovery codes, or other secrets by email. Use the encrypted vault workflow inside 5Line OS for sensitive business information.
Use the email sign-in link on the sign-in screen to recover access on a new device. Password users can request a recovery email from the web sign-in screen.
Open 5Line Account, choose Restore Company Backup, review the record count, and confirm the local copy. Restore never replaces the current or hosted company. Attachment files and receipt scans must be reconnected from their original storage; Vault secrets are not included in company backups.
Open Assistants in 5Line OS to review access for the current company. Each connection is added or removed in the assistant that uses it. 5Line OS keeps permissions separate by company, excludes Vault secrets and private working notes, and sends proposed work to the owner Inbox for review instead of changing records directly.
Direct connected access is in private testing and is not publicly available. ChatGPT is the current test target; Claude compatibility has not yet been verified. The Company Brief remains available as a manual fallback.
Signed-in users can initiate deletion from 5Line Account in the native app or Settings on the web. Export any company data you need first. The request is targeted for completion within seven days and can be cancelled in the app until processing begins.
