A change in the "Last Updated" date indicates that the Policy has been updated or edited, and that the updated or edited version supersedes any previous version immediately upon release.

Definition of Terms

Personal Information

Personal information means data recorded in electronic or other form that can be used to identify or contact a specific individual. Personal Information is information that identifies the subject of several acts as the same person by a single piece of information (or with simple assistance), and is not personal information if the opposite is true.

Personally identifiable information

Personal Identifiable Information is a type of personal information. If only one piece of information (without any assistance) can directly identify, contact or accurately find the corresponding single specific natural person, then this information is personal identifiable information, and vice versa, it is not personal identifiable information.

Personally identifiable information includes, but is not limited to, real name, date of birth, ID or social security number, biometric information (e.g., photograph, fingerprints, palm prints, iris, subcutaneous capillary distribution, etc.), residential address, telephone number, license plate number, precise GPS latitude and longitude coordinates, etc.

Your IP address when you use our services is desensitized and obscured when we collect, categorize and aggregate it, so we treat it as personal information rather than personally identifiable information.

Non-Personal Information (NPI)

Non-personal information is data that is recorded in any form, but which cannot itself be directly linked to any particular natural person. Typically, this data is categorized and aggregated so that it is virtually impossible to recover any relevant information about a specific individual from this data.

When non-personal information is used in combination with personal information, such information is treated by us as personal information.

Unique Identifier

A unique device identifier (unique ID or UUID) is a string of characters that can be used to uniquely identify a device. It is usually programmed into the user's device by the device manufacturer or sent to the browser by the server to distinguish between the device or the user.

Browser Metadata (Cookies)

Cookies are small pieces of data sent to the user's browser by the server and stored locally, and may contain anonymous unique identifiers that are carried and sent to the server the next time the browser makes another request to the same server. Typically, it is used to tell the server whether two requests came from the same browser or user, such as for maintaining the user's login status.

Services we provide

The services we provide include, but are not limited to, websites, online services, interactive applications, and email.

Collection and Use of Personally Identifiable Information

We do not actively collect any personally identifiable information through the services we provide. Ever.

Our Use of Cookies and Other Technologies

The services we provide may use cookies and other technologies such as Pixel Tags, browser beacons, HTML5 fingerprints, TLS handshake fingerprints, etc.

These technologies help us to better understand user behavior (such as which parts of our site a user has viewed) and to distinguish between natural persons and automated processes.

We may also use cookies to store Session information, which contains your "login status".

We treat information collected through cookies and other technologies as non-personal information because others cannot use this information to retrieve any personal data about you.

We do not use cookie technology to disclose to any third party, or to assist a third party in collecting any personal information about you.

Information We Collect and What We Use It For

We actively collect performance and usage statistics for the Site and Application. "Performance and usage statistics" include.

  • Referral source, frequency of visit, date and time of visit, behavior flow, time spent, browser used
  • Device brand, vendor, model, screen size, and operating system
  • Network operator and geographic location only to the exact continent or province
  • Application and website launch, loading speed, critical runtime
  • Performance data from different content delivery network service providers in your network environment
  • **Serious errors and related error messages for applications and websites that do not contain personal information

The above data will not be considered personal information according to our definition of "personal information".

We will contact you if we need certain information to investigate specific errors in certain specific applications. The information will not be actively uploaded until we have your authorization.

In addition, as with most Internet services, our servers automatically collect certain information, such as your IP address and HTTP request headers. This information is generally stored in log files and deleted within 73 hours of collection.

We generally use this information for internal purposes such as auditing, analysis, and research; to protect our services from intrusion; to administer the site; to understand user behavior on the site; to understand and analyze trends; to gather information about the overall audience characteristics of our user base; and to create, develop, and improve the services we offer.

We will not use the information we collect for any content or advertising.

How we transmit, process, store and protect the information we collect

The online services we provide use encryption technologies, such as Transport Layer Security (TLS), to protect the information we collect from intermediaries during transmission.

Analytical information we collect will be categorized and aggregated for the purposes described in the preceding terms.

Any non-analytical information and any other information not required for review and research purposes (e.g., complete, non-desensitized and obscured IP addresses) will be removed at the aggregation stage.

Information for analytical purposes will be stored on computer systems with limited, required authorized access that are protected by mathematical algorithmic encryption and/or physical security measures, as well as when we use storage services provided by third parties. These measures are unlikely to be broken in a short period of time in modern computer systems.

We will retain the information collected for as long as it takes to achieve the purposes described in this Privacy Policy. Generally, this information will be deleted within 30 days of the initial upload, unless storage for a longer period is required by law or regulation.

Third Party Sites and Services

The services we provide may contain products and services from third parties or contain links to them. For example, we use the Cloudflare content distribution web service, the jsDelivr open source content distribution web service, the Disqus review system, and others.

We may also obtain information about you that is collected by them through third parties. Our access to and use of such information will not be governed by this Privacy Policy. However, the information that third parties may disclose to us will still be subject to their privacy policies.

Personal information collected by third parties, which may contain location data or contact information, is subject to the third party's rules regarding privacy. We want you to be aware of these third party privacy rules. We are not responsible for the privacy policies of third parties.

We do not share any information with third parties for any content, marketing purposes, or advertising.

Government Requests

We have never built any "back doors" or any other means of access into the services we provide. We do not voluntarily disclose any information to any government. Ever.
