Yuewu provides document upload and learning tools. Content uploaded by users is
supplied by those users, and **the platform does not pre-screen all user-uploaded
content**. We respect intellectual property rights and require every user to
ensure they hold the necessary rights before uploading, publishing or sharing
any material.
If you believe content on our platform infringes your rights, please send the
following to:
saipukeji@sypro.tech
Your notice must include:
1. Proof of ownership — registration certificate, publishing contract, or
other evidence that you hold the rights;
2. Identification of the allegedly infringing material — title, link, or
other information sufficient for us to locate it;
3. Your contact details — name or organisation, mailing address, phone
number, and email;
4. A statement of good faith and accuracy, signed by the rights holder or an
authorised agent (agents must attach proof of authorisation).
We may be unable to act on incomplete notices; we will reply explaining what is
missing.
Upon receiving a valid notice we will review it and take appropriate action
within 3 business days, which may include making the material inaccessible,
taking it down, or deleting it, and notifying the uploader.
In urgent or manifestly infringing cases we may take material down first and
review afterwards.
If your material has been taken down and you believe this was a mistake, you may
appeal: in the app, go to My Documents → the document → Appeal and submit
your reasons.
Your appeal should explain why you are entitled to upload and distribute the
content. We will re-examine the case and restore the material if the appeal
succeeds.
Accounts that repeatedly upload infringing material may have their upload or
publishing privileges restricted, up to termination of service.
