Privacy notice

Updated 25 October 2026

Account and verification

Registration stores your email and a one-way password hash. Email codes verify registration, sign-in and password resets. Sessions use HttpOnly cookies, without exposing the session token to page scripts.

Searches and allowance

The server stores search conditions, search tickets and daily usage to serve results, support paging, avoid counting duplicate searches, and prevent abuse. The Qingyan index stays on the server and is not included in plugin downloads.

Orders and membership

Only demo orders are currently available. A demo order records the account, plan, quoted price and creation time. It does not charge you, collect payment proof or activate access.

Research materials

Paper and proposal materials in the local plugin are stored locally by default. Model features send the necessary content to your selected host model. Website registration does not automatically upload these materials.

Security and administration

Authorized administrators can view necessary account, usage, order and audit records to operate the service. Passwords, verification codes and knowledge-index encryption keys are not displayed in the admin interface. The configured email service delivers verification messages.

Account management

You can sign out or use an email code to reset your password and revoke existing sessions. Operational contact and data-deletion channels will be added before paid purchasing opens.
