ChinaByteDance bars self-paid Claude and Codex accounts from L4 code.
The rule also covers Feishu documents company-wide, with some Seed team exemptions.
L4 repositories hold the core architecture of ByteDance’s major businesses, and vice president Hong Dingkun says leaks at L3 or above carry serious consequences.
Hong denied the restriction is meant to push staff toward ByteDance’s own tools.
Employees are asking where the data security boundary lies and whether in-house tools suffice.
