Privacy

The contact form stores your message and optional name and email address, together with the article address, request type and submission time.

Messages are stored by the site and can be viewed only by signed-in administrators. Do not submit identity numbers, medical records or other sensitive information.

A hashed network address is used for short-term rate limiting to reduce abuse. The administration panel uses a session cookie. WhatsApp sharing opens a separate service.

Submit data-related requests through the contact form or info@bizdenduyun.com. Publisher and contact details are on the masthead page. Retention periods and detailed processing conditions remain to be specified.
