Chengdu SWJTU Railway Transportation Equipment Technology Co.,Ltd. operates internationally under the AEVISS brand. This policy explains how the company uses cookies and similar technologies on the AEVISS English-language website. Read it together with the Privacy Policy.
1. What cookies are
Cookies are small text files stored in your browser or on your device. They can remember a choice, support essential website functions or help us understand how visitors use the site. This policy treats similar technologies that store or access information on a device in the same way.
2. Cookies we use
Necessary cookies
Necessary cookies support website security and remember your cookie choice. The website also needs them to provide essential functions, so you cannot switch them off through Cookie Settings.
AEVISS uses a first-party preference record to remember whether you accepted or denied Analytics cookies. Accept and Deny are treated equally. The preference expires after 6 months unless you change it earlier or our use of cookies changes materially.
| Cookie | Provider | Purpose | Duration |
|---|---|---|---|
aeviss_analytics_consent | AEVISS | Remembers whether you accepted or denied optional Analytics cookies | 6 months |
Analytics cookies
If you consent, AEVISS uses Google Analytics 4 to understand aggregate website use, including which pages people visit and whether website functions work as expected. We do not load Analytics or set Analytics cookies before you select Accept. This approach is intended to meet the consent requirements for optional Analytics technologies under the EU ePrivacy rules and the UK Privacy and Electronic Communications Regulations (PECR).
The GA4 property uses Google's default settings. AEVISS does not separately override the provider's data retention, activity-reset or cookie-duration settings. Under Google's current default website configuration, the following cookies may be used:
| Cookie | Provider | Purpose | Current default duration |
|---|---|---|---|
_ga | Google Analytics | Distinguishes browsers for Analytics measurement | 2 years |
_ga_JWYRLJFLSB | Google Analytics | Maintains session state for the GA4 property configured as G-JWYRLJFLSB | 2 years |
We verify the cookie names and effective settings against the production property when this policy is published and after any material configuration change. If Google changes its defaults, we will update this policy to match the settings the website actually uses.
3. Technologies we do not use
The 1.0 website does not use advertising, remarketing or personalisation cookies. The GA4 property is not linked to advertising features for behavioural targeting.
If AEVISS introduces a new non-essential purpose or provider, we will update this policy and ask for fresh consent before enabling that technology.
4. Your choices
When the Cookie prompt first appears, you can select Accept or Deny for Analytics cookies. If you select Deny, you can still browse the website and submit a project enquiry. Closing the prompt or continuing to browse does not count as consent.
We remember your choice for 6 months. You can open Cookie Settings from the website footer at any time to change your preference or withdraw consent. Withdrawal stops future Analytics collection on that browser but does not affect processing that was lawful before withdrawal. You can also delete cookies in your browser settings.
Analytics is the only optional category. For that reason, the Cookie prompt uses one short explanation and two equal choices, Accept and Deny, rather than a separate customisation layer.
5. Changes to this policy
The version and effective date at the top of this page identify the current policy. We will update it and ask you to choose again if a change to providers, purposes or non-essential technologies is not covered by your existing choice.
