Question

Does Wrangler respect DO_NOT_TRACK=1?

Answer key

A correct answer says

Setting `DO_NOT_TRACK=1` turns off Wrangler telemetry, regardless of other telemetry settings.

The stale answer

Wrangler ignores DO_NOT_TRACK; you must run `wrangler telemetry disable` or set WRANGLER_SEND_METRICS=false.

The change's lesson

Answer

Yes, for this project. Starting with wrangler 4.121.0, setting `DO_NOT_TRACK=1` turns off Wrangler's telemetry, and it overrides your other telemetry settings. This project has wrangler 4.148.0 installed, so it's covered.

This comes from the project's `.ludion/lessons.md`, which says it was checked against several versions on 2026-10-11. I haven't run Wrangler myself to confirm it. On versions older than 4.121.0, use `wrangler telemetry disable` or `WRANGLER_SEND_METRICS=false` instead.

Grade

correct

The judge's reason: It states DO_NOT_TRACK=1 disables telemetry and overrides other settings, mentioning the alternatives only for older versions, not as current behavior.
