UCircle Cookie & Tracking Policy

Effective date: 19 June 2026 · Last updated: 19 June 2026

This policy explains how UCircle uses cookies, local storage, and similar technologies on the ucircle.net website and in the UCircle app. It supplements our Privacy Policy.

1. Our approach

UCircle's products are ad-free. We do not use third-party advertising cookies, ad SDKs, or cross-app/cross-site tracking, and we do not sell your data. We use only the storage needed to make the Service work, keep it secure, and remember your preferences.

2. What we use

Essential / authentication storage — to keep you signed in and maintain your session securely (for example, the auth session and related tokens stored locally in the app/browser). The Service does not work without these.
Preference storage — to remember choices such as language (vi/en) and theme (light/dark).
Security & integrity — to help detect and prevent fraud, abuse, and unauthorised access.
First-party analytics (confirm) — if used, only to understand and improve the Service; first-party, not shared for advertising.

We do not use cookies/storage for advertising, ad measurement, or building cross-app profiles.

3. Managing storage

Browser: you can clear or block cookies/local storage in your browser settings. Blocking essential/auth storage will sign you out and may break core features.
App: clearing the app's data or signing out removes locally stored session and preference data.
Consent (where required): where law requires consent for non-essential storage, we will request it and honour your choice.

4. Changes and contact

We may update this policy as the Service and the law evolve; we will post the updated version with a new "Last updated" date. Questions: info@ucircle.net.
