This Cookie Policy explains how Halley (“we”, “us”, or “our”) uses cookies and similar technologies on our website and mobile application (the “App”).

1. What Are Cookies?

3. Essential Cookies

Session and authentication cookies from Supabase are essential for the App to function. Without these, you would not be able to log in or maintain your session. These cookies cannot be disabled while using the App.

4. Third-Party Cookies

Google AdMob may set cookies and collect device identifiers to serve personalised ads. These cookies are governed by Google's own privacy policy. We do not control the cookies set by third-party ad networks.

5. How to Manage Cookies

You can manage or disable cookies through the following methods:

Browser settings: Most web browsers allow you to control cookies through their settings. You can typically find cookie settings under “Privacy” or “Security” in your browser preferences.
Device settings: On mobile devices, you can manage app-level permissions and advertising preferences:
- Android: Settings > Privacy > Ads > “Opt out of Ads Personalisation”
- iOS: Settings > Privacy & Security > Tracking > disable “Allow Apps to Request to Track”
Ad personalisation opt-out: You can opt out of personalised advertising from Google by visiting Google Ad Settings.

Note: Disabling essential cookies (authentication) will prevent you from using the App. Disabling advertising cookies will not remove ads but may result in less relevant advertisements.
