By Erik Bergstedt, Agent Wranglers. Updated 2026-10-20.

- Level: Optional
- Chapter: [Standard addresses](https://agentwranglers.se/playbook/website/standard-addresses)
- Rule: If you honour Global Privacy Control, a browser signal that means "don't sell or share my data", say so in `/.well-known/gpc.json`.
- How: Serve the JSON below, with the date you last changed how you handle the signal. Explain in the privacy policy what you do with it.
- Check: The file answers 200 as JSON.

Example:

```json
{ "gpc": true, "lastUpdate": "2026-03-02" }
```
