LCT Website Privacy Notice

Version 2.0Effective Last updated

This page explains only what happens when you browse lct.lenscript.cn. The privacy policy for the 光轴脚本 LCT app and LCT accounts is a separate document linked in section 1.

1. What this page covers

光轴脚本 LCT is operated by Lenscript (光子方程), an independent developer team ("we", "us"). Contact: donaldkuke@gmail.com.

The privacy policy for the 光轴脚本 LCT app (Android, listed as Lenscript / 光轴脚本) and LCT accounts is https://lenscript.cn/privacy#en — accounts, location and weather, the AI assistant, place submissions, feedback, retention and account deletion (account deletion) are all described there. This page applies only to browsing the website lct.lenscript.cn; where the two differ about the app or accounts, that policy prevails.

2. What the website (lct.lenscript.cn) collects

No account is needed to browse this site. It is a static website and collects only:

  • Server access logs: IP address, time, request path, browser User-Agent and referrer, used to troubleshoot and to defend against attacks. Logs rotate by size and are kept for at most 30 days before being overwritten.
  • Content delivery: the site is served through Cloudflare for CDN and security. Cloudflare processes your IP address and request headers in transit; see its privacy policy.
  • Scripts Cloudflare may inject: we place no third-party analytics, advertising or social plugins on these pages and set no tracking cookies. The site is, however, delivered through the Cloudflare CDN, and Cloudflare may inject scripts of its own at the edge — its email-address obfuscation script (/cdn-cgi/scripts/…/email-decode.min.js) is one you can see today, and when automatic injection is switched on for its Web Analytics it also adds a performance-measurement script (static.cloudflareinsights.com/beacon.min.js). That script is not configured by us, sets no cookie and is not used for advertising or cross-site tracking; it reports page performance and page views to Cloudflare, and Cloudflare’s own privacy policy governs it. A content-blocking browser extension will stop it.
  • Page-view counting: pages report "which path was opened", the page title and the referrer to our self-hosted counter (markstats.lenscript.cn, GoatCounter). It is first-party, sets no cookie, creates no device identifier and never reads page content. To opt out permanently run localStorage.setItem('lens_telemetry','0') in your browser console.
  • Emails you send us: the "register your email" and "buy by email" buttons simply open your own mail app; what we receive is the message you send, used only to reply and for the purpose you asked for.

3. Your rights

Under China's Personal Information Protection Law and any law that applies where you live (such as the GDPR or CCPA) you can:

  • access and copy the personal information we hold about you;
  • correct inaccurate or incomplete information;
  • delete your information or delete your account (where one exists);
  • withdraw consent and restrict or object to certain processing (for example turn off anonymous statistics);
  • receive a copy of your data in a common machine-readable format (portability);
  • complain to the supervisory authority where you live.

To exercise a right, email donaldkuke@gmail.com and include your registered email or another way for us to identify you. We reply within 15 business days; to protect your data we may first verify your identity. Requests are free unless they are clearly repetitive or unfounded.

4. Where data is stored and international transfers

Our servers are located in mainland China. Processing outside China happens in these cases: Cloudflare's global network handles your requests in transit; payment providers and app stores may process payment data where they are established; and any other provider named in the relevant section of this policy. We send each provider only the minimum needed for its task and require protection equivalent to this policy.

5. Changes to this policy

We update this policy on this page and revise the date at the top. For material changes to what we collect, why, or with whom we share it, we give at least 15 days' notice on this page, in the app or by email. Previous versions are available on request. The current version lives at https://lct.lenscript.cn/en/privacy/.
