Cookie policy

1. Essential cookies

We use two essential cookies:

• wv_session — Encrypted, and holds only the session token and its expiry (up to seven days) — no readable personal information. Turn it off and you cannot sign in.
• wv_locale — remembers the language you chose (en or vi), for up to one year. It holds no personal information.

Both cookies are set by Warrly on this domain; neither is a third-party cookie.

2. Local storage on your device

A few interface preferences (light/dark mode, font size, accent colour) are kept in your browser's local storage (localStorage, under the keys theme and wv:prefs) on your own machine and are never sent to the server.

Your cookie choice is kept in localStorage under the key wv_consent. This record is necessary to know whether you agreed or refused; no cookie is set for it. The choice is remembered for up to 12 months, after which Warrly asks again.

Clearing your browser data removes these entries; clearing wv_consent makes the cookie banner appear again.

3. Advertising cookies (free tier only)

Khi có quảng cáo, chúng nằm trong app iOS và Android và do Google AdMob phục vụ. Trên web hiện chưa có quảng cáo: Warrly không tải script quảng cáo và không đặt cookie quảng cáo trước khi mày đồng ý.

In the app, once you agree, AdMob may read your device’s advertising identifier to select, cap and measure ads. The paid tier has no ads, so it has no ad data.

• Advertising provider: Google AdMob — Google LLC (United States) and Google Ireland Ltd (Ireland). For advertising data, Google is an independent controller.
• Cookies, identifiers and duration: In the app: IDFA (iOS) and GAID (Android), plus Google’s advertising cookies or identifiers (for example NID, IDE); duration per Google’s policy. The web has no ads yet.
• Data received and purpose: Advertising identifier, minimal device information, and impression and click events, to select and measure ads. Non-personalised by default; personalised only after you agree (ATT on iOS, Google UMP for the EU/UK/Switzerland).
• Ad data retention: per Google’s Ads/AdMob policy. Warrly stores no advertising data.

4. Changing or withdrawing your choice

Open “Cookie settings” in the footer at any time. Choose “Reject non-essential” to turn advertising off immediately, or “Manage” to switch each category on or off.

Withdrawing consent does not make earlier processing unlawful, and it does not block you from using the free tier.
