Privacy policy
In short: we collect very little data, and we never sell your data to anyone.
1. Data we do not collect
XSMB 300 Days has no accounts, no sign-up forms and sets no advertising or tracking cookies. Number searches and table filters run entirely in your browser and are never sent to a server.
2. Technical data
Like any website, the hosting server may keep access logs (IP address, browser type, time of visit) to operate the site and protect it from attacks. These logs are kept for a short period by the hosting provider.
3. Third-party services
The site uses fonts from Google Fonts. When fonts load, your browser connects to Google's servers. If we add visitor analytics in future, this policy will be updated before it goes live.
4. Emails you send
If you email us, we use your address and message only to reply to you and do not share them with third parties.
5. Your rights
You may ask to see, correct or delete information you have sent us, in line with Vietnamese personal data protection law. Send requests to lienhe@xsmb300ngay.com.
6. Children
The site is intended for people aged 18 and over and does not knowingly collect information from children.
7. Changes
When this policy changes, the date at the bottom of the page is updated.
