1. Why we use cookies / Vì sao chúng tôi dùng cookie
Cookies are small text files stored in your browser. We use them for three things:
- To make the site work (mandatory) — e.g. remembering that you're signed in, storing your language preference.
- To understand how the site is used (only with consent) — page views, performance metrics.
- To run marketing experiments (only with consent) — A/B tests, attribution.
You can change your choice anytime by clicking "Cookie preferences" in the footer.
Cookie là tệp văn bản nhỏ lưu trên trình duyệt. Chúng tôi dùng để (1) chạy site, (2) hiểu cách site được dùng, (3) chạy marketing. Bạn có thể thay đổi lựa chọn bất kỳ lúc nào qua "Cookie preferences" ở footer.
