# Acceptable Use > Portal rule. Last updated 2026-08-07. The full Terms of Use are > published and linked in the footer. Use this site and any software from it lawfully and honestly: no attempts to breach, probe, or overload the service; no impersonating Opti-Gen Core Systems or its clients; no using our tools to harm others. Public apps are provided for legitimate personal and business use, under the Terms of Use. The access-request forms are for genuine requests only — don't submit other people's email addresses. Anything that hurts the service, its users, or third parties is out of bounds, and portal access can be withdrawn for it. Good-faith security research reported through the Report Issues channel is not a breach of this policy.
