PRIVACY & CHOICE
Privacy notice
Updated November 5, 2026
This notice covers the Chinese and English website at linght.com, operated by Shenzhen Linght Technology Co., Ltd. You can browse without an account. The feedback form does not ask for your name, phone number or email address.
Analytics settings
Analytics are off by default. Use the button below or “Privacy settings” in any page footer, then choose “Allow” or “Reject.” You can still browse, leave feedback and vote if you reject analytics. Analytics stay off when your browser has Do Not Track (DNT) enabled.
Change analytics choiceIf you previously allowed analytics, you can switch to “Reject” at any time. The site stops recording new events, discards queued events and clears analytics identifiers in your browser. Open tabs on the same domain in that browser also update. Records already sent to the server follow the retention schedule below.
What we record if you allow analytics
We run our own analytics service to understand how people use our content and to improve the site’s navigation and reading experience.
- Random identifiers link visits from the same browser or tab session. They are not tied to a name, contact details or a user account.
- Visit records include the time, page path, title, language, referring page and campaign (UTM) parameters in the URL, along with browser information, screen and window dimensions, and time zone. We also record time on page, scrolling, which sections come into view, link clicks, interactions with social links and QR codes, and form submissions. For submissions, analytics record the form type and validation result only.
- The analytics server receives your IP address with the request. The analytics database stores only a hash of that address, calculated with a random salt that changes daily.
- The site uses no third-party advertising trackers. Analytics for social links and QR codes cover interactions on this site.
How long we keep analytics
The server periodically aggregates and deletes analytics records older than 180 days. Long-term totals contain only counts by date, event type, page path and page language. Blog view counts combine recent records and historical totals from visits included in analytics.
How we handle your message
We use messages to understand your ideas, requests and interest in talking with us. The server saves your selected topic, message, submission time and a random reference to avoid duplicates if you retry. If you’d like a reply to an investment or conversation message, you can include your email in the message. We use it only to reply to that message. Please leave out other personal information. The server periodically deletes messages older than 180 days.
Voting and website services
Lab voting works independently of analytics. The server stores a random vote identifier, your choice and the vote time to prevent duplicate votes under the same identifier, restore your voting status and calculate results. Vote records currently have no automatic expiry.
If you follow a link to a social platform, GitHub or another external service, that service handles information under its own privacy policy.
Hosting and content delivery services may process IP addresses, request times and URLs to deliver and secure the website. The voting and feedback endpoints also use IP addresses to limit request rates. These processes are independent of optional analytics.
Cookies and browser storage
The site uses the browser storage below for your settings, analytics identifiers and vote identifier. Analytics do not use HTTP cookies.
| Storage item | Purpose and activation | Lifetime |
|---|---|---|
linght-consentlocalStorage | Records your permission or refusal, the time you chose and the settings version. | 180 days, after which we ask again |
linght_vidlocalStorage | Links visits from the same browser after you allow analytics. | Cleared when your choice expires or you withdraw permission |
linght_sidsessionStorage | Links visits in the same tab session after you allow analytics. | Until the tab session ends, the choice expires or permission is withdrawn |
linght-lab-vote-tokenlocalStorage | Created when you first try to vote, to prevent duplicate votes and restore your voting status in this browser. | Until you clear site data in this browser |
Settings are saved for each browser and website domain. If your browser cannot save them, your choice applies only to the current page.
