Cookie Policy
This is an English translation for convenience. If it differs from the Spanish version, the Spanish version prevails.
Strix Mail uses only what it needs to work: two first-party cookies to keep your session and protect it, and two preferences stored in your browser. We do not use third-party, analytics or advertising cookies, and we do not load scripts or fonts from other sites.
Since everything is strictly necessary, we do not ask you to accept a cookie banner: without these cookies you cannot sign in.
Browser local storage
In addition, the app stores the following in your browser's local storage (localStorage), without sending it to our servers:
| Key | What it stores | Duration |
|---|---|---|
strix-mail-theme |
Your theme preference: automatic, light or dark. | Until you change it or clear the site's data. |
strix-mail-layout |
The layout of the mail screen: panel widths, whether the sidebar is collapsed, and which mailboxes you collapsed in it (by internal identifier). | Until you change it or clear the site's data. |
Mobile app
The mobile app uses the same mechanisms inside its web view. It does not include advertising or analytics SDKs and does not use the phone's advertising identifier.
How to delete them
You can delete cookies and site data from your browser settings. If you delete mail_session, you are signed out; if you delete what is stored in localStorage, the theme and layout go back to their defaults.
