What this website and the Xonera app store in your browser, and how to control it.
What cookies are
Cookies are small files a website saves in your browser. Browser storage (such as local storage) works in a similar way. Both let a site remember things between visits, like whether you are signed in.
On this website
This website, xonera.xyz, does not set its own cookies or use analytics. Cookies and browser storage come into play once you open the Xonera app.
In the Xonera app
| Purpose | Set by | What it does |

| Preferences | Xonera | Remembers your theme, focus timer and practice progress (browser storage). |
| On-device notes | Xonera | Holds your mood check-ins and worry notes. Never sent to us (browser storage). |
| Analytics | PostHog | Measures which pages and features are used (a cookie and browser storage). |
| Diagnostics | Sentry | Reports errors and records a sample of sessions so we can fix problems. |
| Payments | Stripe | Prevents fraud on payment screens. Set only when you pay. |

Your choices
You can view, block or delete cookies and site data in your browser's settings, usually under Privacy or Site settings. Blocking essential storage will sign you out of the app, and clearing site data permanently removes your on-device mood and worry notes.
We do not currently respond to browser "Do Not Track" signals.
