This Cookie Policy explains how Shenzhen Weichat Technology Co., Ltd. (“Weichat,” “E-Weichat,” “we,” “us,” or “our”) may use cookies and similar technologies on the following websites:
- https://e-weichat.com/
- https://weichatconnectors.com/
- https://weichatsz.com/
- https://eweichat.com/
Cookies and similar technologies can help websites operate, remember preferences, measure performance, and understand how visitors interact with online content.
The technologies used may differ between websites and may change as our website features and measurement tools are updated.
1. What Are Cookies?
Cookies are small text files stored on your device by a website or service. They may contain information used to recognize a browser, maintain a session, remember preferences, or measure website activity.
Other technologies, including tracking pixels, tags, scripts, and local storage, may perform similar functions.
Cookies may be set by the website you visit (“first-party cookies”) or by another service integrated into that website (“third-party cookies”).
2. Why We Use Cookies and Similar Technologies
Depending on the website configuration and your choices, we may use the following categories of cookies and similar technologies.
2.1 Strictly Necessary Technologies
These technologies support essential website functions, security, network management, or services you have specifically requested.
Where a technology is strictly necessary under applicable law, it may be used without consent where the relevant legal requirements are satisfied.
2.2 Analytics and Performance Technologies
We may use Google Analytics 4 or other configured analytics technologies to understand how visitors use our websites.
Depending on the configuration, analytics information may include pages viewed, session information, referring sources, browser or device details, and interactions with website elements.
We use this information to understand website traffic, identify technical issues, evaluate content performance, and improve the user experience.
Analytics technologies that require consent under applicable law will be activated or managed according to the consent choices and technical controls applicable to the relevant website.
2.3 Advertising and Measurement Technologies
We may use Google Ads and related technologies to measure advertising performance and understand actions taken after visitors interact with our advertisements.
Depending on the features enabled, these technologies may help us measure visits, inquiry form submissions, and other defined business conversions.
Advertising technologies may use cookies, advertising identifiers, or information associated with an advertising interaction. Some configurations may also support audience creation or personalized advertising.
The specific technologies used, and whether they involve personalized advertising or the sharing of information for advertising purposes, must be confirmed from the actual account and tag settings.
Where required by law, we will obtain consent before using the relevant technologies and will respect applicable opt-out choices.
2.4 Functional Technologies
If enabled, these technologies may remember preferences or settings that make the website easier to use, such as language or other selected options.
We will describe and manage these technologies according to their actual functions and the requirements of applicable law.
3. Examples of Cookies That May Be Used
The following table provides examples of technologies that may be relevant to our websites. It is not a confirmed inventory of cookies currently active on every website.
| Cookie or technology | Possible purpose | Retention |
|---|---|---|
_ga | Used by Google Analytics to distinguish browsers or users for analytics purposes | Depends on configuration and browser restrictions; often configured for up to two years by default |
_ga_<container-id> | Used by Google Analytics to maintain analytics session state | Depends on configuration and browser restrictions; often configured for up to two years by default |
Google Ads-related cookies, such as _gcl_* where enabled | May support advertising conversion measurement | Depends on the specific cookie, tag configuration, and browser behavior |
| Essential session or security cookies | May support session management, security, or website operation | Depends on the service and its configuration |
| Preference cookies, if used | May store selected settings or preferences | Depends on the relevant feature and configuration |
The actual names, providers, purposes, and expiration periods may vary. Browser settings may also restrict cookie lifetimes.
We will update this Policy if necessary to reflect material changes to the technologies used on our websites.
4. Third-Party Services
Our websites may integrate services provided by third parties, including Google Analytics and Google Ads.
These services may process information according to their own terms, privacy notices, and technical configurations. The information collected depends on the features enabled, the tags deployed, and the consent settings in place.
For more information, please review Google’s relevant policies and documentation:
- Google Privacy Policy: https://policies.google.com/privacy
- Google Analytics cookie information: https://support.google.com/analytics/answer/11397207
- Google Ads consent management information: https://support.google.com/google-ads/answer/10000067
Links to third-party websites are provided for convenience. Their content and policies are controlled by the relevant third parties.
5. Your Cookie Choices
Where our websites provide a cookie banner or preference management tool, you may use it to review available categories and make or change your choices.
Depending on the website and applicable law, the available controls may allow you to:
- Accept optional cookies.
- Reject optional cookies.
- Select individual cookie categories.
- Withdraw or change a previous choice.
Strictly necessary technologies may not be subject to the same consent requirements as optional technologies. We will distinguish them where required.
Where applicable law requires prior consent, optional cookies and similar technologies should not be activated before the required consent is obtained. Where consent is required, refusing optional cookies should not prevent access to website functions that do not depend on those technologies.
If a website does not yet provide a functioning preference management tool, the relevant implementation should be reviewed before publication of a statement suggesting that such controls are available.
6. Browser Controls
Most browsers allow you to review, block, or delete cookies through their settings.
If you block all cookies, some website features may not function as intended. Deleting cookies may also remove previously saved preferences.
Browser-level controls do not necessarily manage every form of tracking technology or automatically communicate a legally valid opt-out for every purpose. Use the website’s preference controls where available and applicable.
7. Cookie Consent and Advertising Measurement
Where required by applicable law or relevant platform policies, we will configure our consent mechanisms and tags to respect visitors’ choices.
If Google Consent Mode is implemented, it can communicate consent signals to supported Google tags and adjust their behavior. It does not, by itself, provide a cookie banner or collect consent from visitors.
The actual behavior depends on whether a basic or advanced implementation is used, the default consent settings, the categories configured, and the tags deployed.
We will review our implementation to ensure that the consent interface, tag behavior, and disclosures are consistent with the requirements applicable to each website and audience.
8. Changes to This Cookie Policy
We may update this Cookie Policy when we change our websites, introduce or remove technologies, modify our analytics or advertising configuration, or respond to legal requirements.
The latest version will be published on the relevant website with an updated “Last Updated” date. Where required, we will provide additional notice or obtain consent.
