== [mediaqueries-5] Security and privacy self-review for prefers-contrast 2021-08-04 ==
We have conducted a self-review of our spec [prefers-contrast](https://drafts.csswg.org/mediaqueries-5/#prefers-contrast), and the results can be found below.

1. What information might this feature expose to websites or other parties, and for what purposes is that exposure necessary?
The user's preferred color palette is exposed through getComputedStyle and also if the author uses any system color keywords. The use of these colors is necessary, otherwise it's impossible to honor the user's preferences.

Yes

N/A

5. Does this specification introduce new state for an origin that persists across browsing sessions?
No.

Preferred color palette is exposed.

10. Does this specification allow an origin to access other devices?
No

11. Does this specification allow an origin some measure of control over a user agent's native UI?
No

12. What temporary identifiers might this specification create or expose to the web?
None

13. How does this specification distinguish between behavior in first- and third-party contexts?
N/A

14. How does this specification work in the context of a user agent's Private Browsing or Incognito mode?
No difference

15. Does this specification have a "Security considerations" and "Privacy considerations" section?
No, but the related css-color-adjust-1 does: [https://drafts.csswg.org/css-color-adjust-1/#priv-sec](https://drafts.csswg.org/css-color-adjust-1/#priv-sec)

16. Does this specification allow downgrading default security characteristics?
