Understand Safe mode and trust a project

Every project compiles in Safe mode until you trust it. Here is what Safe mode limits and how to trust a project you wrote yourself.

There is nothing to switch on: every project compiles in Safe mode until you trust it.
In Safe mode a document can read only its own project and the installed TeX packages, it cannot run commands from Lua code, and a compile has time and memory limits. This protects you when you open a project from someone else.
If a compile runs for 3 minutes, TeXAnt asks Compilation has exceeded 3 minutes with Stop and Continue. Without an answer, it stops after 10 minutes.
To trust a project you wrote yourself, tap Project actions menu on the left rail, choose LaTeX, then Manage Compilation Trust and Trust Project. You see TRUSTED compilation enabled.
When the project’s files change after you trusted it, the next compile asks again: choose Trust Again or Continue in SAFE.
To go back to Safe mode, open Manage Compilation Trust again and tap Revoke Trust.

The 10-minute limit is a setting: Settings → LaTeX Settings → Compile time limit in Safe mode. It is on by default and has no effect in trusted projects.
Trust only projects whose source you know. Commands that run outside programs, such as \write18, stay off in both modes.
