Chính sách bảo mật / Privacy Policy

1. Dữ liệu chúng tôi xử lý / Data we handle

Message and file contents are end-to-end encrypted on the sender's device; the server stores and relays only ciphertext and cannot read contents or file names. The server keeps public keys, display names, chosen usernames, group roles and timestamps to deliver messages. IP addresses are used transiently for anti-abuse rate limiting and are not stored long-term.

2. Google Drive / Google user data

DuckMess uses only the drive.file scope, on the Google Drive of the server owner, to create one folder and store encrypted attachments in it. It creates, reads and deletes only files it created and accesses no other Drive files. Google user data is not shared, sold, used for advertising, or used to train AI models. The Drive authorization stays on the owner's server and can be revoked at any time at myaccount.google.com/connections. DuckMess's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

3. Lưu giữ và xóa / Retention and deletion

Tệp đính kèm được giữ cho tới khi người gửi hoặc người nhận chọn "xóa cho cả hai"; khi đó bản mã hóa bị xóa hẳn khỏi máy chủ và Google Drive. Tin nhắn chờ chỉ nằm trên máy chủ cho tới khi được giao.
Attachments are kept until the sender or recipient chooses "delete for both"; the encrypted copy is then permanently deleted from the server and Google Drive. Queued messages stay on the server only until delivered.

4. Chia sẻ / Sharing

Không chia sẻ dữ liệu với bên thứ ba, trừ khi pháp luật bắt buộc.
We do not share data with third parties, except where required by law.
