Cookie Policy

1. Cookies and browser storage

Cookies are small records stored by a browser that can be sent with later requests to a website. Local storage is browser storage accessible to pages on the same origin. The website uses local storage to remember your analytics choice; this preference is distinct from optional analytics cookies.

This policy applies to https://websm.net, operated under the QTech brand by HAN QUANG TRADING SERVICES COMPANY LIMITED.

2. Essential consent preference

The local-storage entry qtech.analytics-consent stores whether you accepted or rejected analytics, the consent version, the time of your choice and its expiry. It contains no name, email address or enquiry content and is used to honour your selection, not to measure browsing behaviour.

The preference lasts up to 180 days and is shared by the English and Vietnamese pages in the same browser on this website. You will be asked again if it expires or the consent version changes. Clearing browser storage may prompt another choice; a rejection-only tab safeguard can continue to keep analytics off. The current consent version is 1.

If browser storage cannot save a choice, the essential first-party cookie qtech_analytics_optout can remember that analytics remains rejected for up to 180 days. It contains only an opt-out flag, applies across this website and is not an analytics identifier.

Before using a saved acceptance, the website checks that local storage is writable using qtech.analytics-storage-probe. The website attempts to remove this temporary entry immediately; browser restrictions may require you to clear it through browser controls. The check neither changes your preference nor extends its expiry, and does not record browsing behaviour. If it fails, analytics remains off.

When saving a choice fails, a rejection-only guard in the current tab’s window.name can keep analytics off across reloads and the English and Vietnamese pages. It is limited to this website origin and consent version, expires within 180 days, and contains no analytics identifier. A successfully saved new choice clears the guard.

If browser storage is unavailable, the site can honour your choice for the current visit but may ask again on a later page or visit. Clearing or blocking storage does not prevent access to the website.

3. Optional Google analytics

Google Tag Manager and Google Analytics are loaded only after you accept analytics. Before acceptance, and when you reject analytics, the website does not load those Google tags or send website analytics requests to Google. This includes visitors browsing with JavaScript disabled.

After acceptance, Google Analytics may set first-party cookies such as _ga and _ga_* to distinguish pseudonymous visits and maintain session information. The precise cookies and their expiry depend on Google’s tag configuration and browser behaviour. Google documents a default two-year expiry for its main first-party analytics cookies; settings or browser restrictions can change that period.

Optional measurements include page views, site language, browser/device information and selected interactions such as contact-link clicks or a company-profile download. The site does not send message contents, email addresses supplied in an enquiry or telephone conversation contents as analytics event data.

The website consent controls keep advertising storage, advertising personalisation and advertising user-data consent denied. Accepting analytics is not consent to advertising tracking.

4. Manage or withdraw your choice

The first-visit banner offers Accept analytics, Reject analytics and Cookie settings. No optional category is preselected. You can reopen Cookie settings through the floating button at the bottom left after making a choice, the button below or the footer link on any page, then save your choice.

When you withdraw consent, the website blocks new analytics events and attempts to remove first-party Google analytics cookies it can access. If Google tags were already loaded, the page reloads when the website can confirm analytics will remain off in the new document. Otherwise, the current document keeps analytics disabled. Browser controls can remove any remaining cookies or storage that the website cannot access.

Your new choice applies to future activity in this browser. It does not remove information Google previously received; use the contact details in the Privacy Policy if you want to make a related personal-data request.

5. Browser controls and other services

Your browser settings can show, block or delete cookies and local storage. Choices are specific to each browser and device. Deleting the consent preference may prompt a new choice; a rejection-only guard can keep analytics off in the current tab. Cookie settings lets you make a new choice. Optional analytics stays off when browser storage cannot save that choice.

Email and telephone links open external applications rather than embedding those services in this website. Their own storage and privacy practices apply when you use them.

6. Questions and changes

For questions about these technologies or your choice, contact [email protected] or 0707780809. More information about personal-data handling is available in our Privacy Policy.

We update this policy when the storage or optional analytics used by the website changes. A material change to the analytics consent request requires a new choice.
