Lamplit – Read Together (Ánh Đèn) — anhden.com and the Android app com.anhden · operated by 3S Labs · updated 9 November 2026
Lamplit is an online 3D library where people from around the world sit and read together. It keeps only what it needs to give you a seat and a character, count your reading time, and keep you in touch with the people you read with. There are no ads and no tracking, and your data is never sold or shared with anyone.
What the library keeps
- When you enter the library (no account needed): a random id stored on your device so the library recognises you next time; the display name, gender and character you choose; your seat and room; the title of the book you are reading (you choose who can see it); your reading time; your reading log, finished books and any reviews you write; the days you visit.
- If you create an account: either your Google account id, when you sign in with Google (we do not keep your Google e-mail, name or photo), or a username you choose and your password, stored only as a one-way hash.
- Friends and messages: friend requests, your friends list, the short messages you send and receive between friends (written by you, up to 100 characters, or picked from presets; deleted after 7 days), the people you block and the reports you send. When you report a message, its text is kept with the report so a moderator can review it.
- Server logs: the IP address and browser type of each request, kept about 2 weeks, to prevent abuse and fix bugs. When a book fails to open, the app sends the browser type and the book file's type and size so we can find the bug.
All data is sent over encrypted connections (HTTPS).
What the library does not keep
- The book files you open yourself (PDF, EPUB…) and your place in them stay on your device and are never uploaded.
- No location, contacts, photos, microphone or camera. No advertising id, no third-party analytics or advertising tools.
Simulated readers
So the library never feels empty, some of the readers in the rooms are simulated characters run by the library itself, not real people. They hold no data about you; a friend request sent to one gets no answer and quietly expires after a few days.
Who can see what
People in your room see your character, display name and, if you allow it, your book title and profile. In Settings you choose, for each of these, everyone, friends only, or nobody. Messages can be read only by their recipient (and by a moderator if the recipient reports one).
Outside services
- Google Sign-In, only if you choose to sign in with Google (under Google's own privacy policy).
- The library's server is rented from Vultr; your data lives on that server.
Delete your account and data
- In the app: open Menu → Account → Delete account. Your account and your character, reading time, reading log, friends, messages, blocks and reports are deleted from the server at once and cannot be recovered.
- By e-mail (if you have no account, or cannot open the app): write to [email protected] with the subject “Delete my Lamplit data” and your display name or username. We delete your data within 30 days and reply when it is done.
- Server logs delete themselves after about 2 weeks. The server's backups, kept in case of a fault, are replaced as they expire, so a deleted account is gone from them too within about 40 days. Books and settings on your device: clear the site's data or uninstall the app.
Age
Lamplit is for people aged 16 and over. We do not knowingly collect data from anyone younger; if you know of such a case, tell us and we will delete it.

Tóm tắt tiếng Việt
Lamplit (Ánh Đèn) do 3S Labs vận hành. Ánh Đèn lưu: một mã ngẫu nhiên trên máy bạn; tên hiển thị, giới tính, nhân vật; chỗ ngồi, phòng, thời gian đọc và tên sách (bạn chọn ai được thấy); sổ đọc, sách đã đọc xong, cảm nhận; nếu có tài khoản thì mã tài khoản Google (không lưu email, tên, ảnh) hoặc tên đăng nhập và mật khẩu đã mã hoá một chiều; bạn bè, tin nhắn giữa bạn bè (tối đa 100 ký tự, tự xoá sau 7 ngày, trừ tin bị báo cáo), danh sách chặn và báo cáo; nhật ký máy chủ (IP, loại trình duyệt) giữ khoảng 2 tuần. Một số người đọc trong phòng là nhân vật mô phỏng do Ánh Đèn chạy, không phải người thật. File sách bạn mở chỉ nằm trên máy bạn. Không quảng cáo, không công cụ đo lường bên thứ ba, không bán hay chia sẻ dữ liệu. Xoá dữ liệu: Menu → Tài khoản → Xoá tài khoản (xoá ngay, không khôi phục), hoặc email [email protected](xoá trong 30 ngày); bản sao lưu trên máy chủ tự thay mới, nên dữ liệu đã xoá cũng hết hẳn trong khoảng 40 ngày. Dành cho người từ 16 tuổi.
