# Where does your AI safety layer process personal data?

By [Astroware](https://astroware.ai/) · As of 1 November 2026 · Last updated 30 October 2026

If your agent sends user messages to a guard model or a personal-data filter, that service handles the same personal data your agent does. So ask the same questions you ask of your model provider: where it runs, whether it saves the text, and whether a data processing agreement is ready.

## Three questions for any safety layer

| Question | Why it matters |
| --- | --- |
| Where are messages checked? | Your customers' reviews ask where personal data goes, and the safety layer is on that path |
| Is the text saved, and where? | Logs of checked messages are copies of personal data |
| Is a data processing agreement ready to sign? | Your privacy team will ask before real customer data flows |

## Our answers, as our site states them

- "The HaloGuard EU API and console run on Google Cloud in the Netherlands and Belgium. This is today's setup, not a promise to keep that region." ([astroware.ai/trust](https://astroware.ai/trust))
- "Every request and reply you send is checked in the EU." ([astroware.ai/eu-mode](https://astroware.ai/eu-mode))
- "We do not save the text you send or the answer in any log, file or database." ([astroware.ai/eu-mode](https://astroware.ai/eu-mode))
- "The model server may keep a processed form of it in memory until the server restarts." ([astroware.ai/trust](https://astroware.ai/trust))
- "Our data processing agreement is ready to sign: write to core@astroware.ai." ([astroware.ai/trust](https://astroware.ai/trust))

**Where Astroware fits:** Our privacy filter looks for personal data in text and masks what it finds. You can try it on your own text with the free PII checker: [astroware.ai/pii-checker](https://astroware.ai/pii-checker). Your text is checked in the EU.
