Website information
Website privacy
This notice covers the public website, business accounts, inquiries and enabled matter services. Historical pilot records remain separately identified.
Who operates this website
EastFiling is a service brand operated by Zhiquan IP. The Mainland China operating entity is 深圳市智圈知识产权代理事务所（普通合伙）. Contact peterlin@eastfiling.com about this website or your inquiry.
Browsing the site
The public website does not use advertising trackers or online card checkout. Signed-in account forms send the entered business information to the service. Hosting infrastructure processes request information, including IP addresses and browser details, to deliver and secure the site.
Light accounts and requests
When you register, we store your business contact and firm details, consent version, review status and non-confidential requests. Passwords are stored as protected hashes, never in plain text. Authentication uses an essential HttpOnly session cookie. Email verification and password-reset codes expire after 10 minutes and are not kept in ordinary email logs. Marketing consent is optional.
Cloudflare processes account and matter metadata. The existing D1 database and private R2 document bucket are restricted to the European Union; website requests may be processed globally. For enabled matter intake services, uploaded originals are kept private. The platform checks access, type, size, version and byte integrity. The matching file versions must also pass virus and file-structure checks in an isolated offline environment before originals or packages containing them are released to the official mailbox through Resend. An attachment-free receipt may be issued while those checks are pending. Security clearance and professional review are separate. Resend processes transactional email, including in the United States; manual replies use the independent peterlin@eastfiling.com Google Workspace mailbox. Provider retention and processing locations follow the applicable terms and verified configuration. No zero-retention or single-region promise is made.
When you switch language, this tab temporarily preserves unfinished business form fields in session storage; it does not store passwords, authentication or roles. The temporary fields are removed after restoration or successful verification.
POA preparation and optional AI classification
Preparing a POA uses the necessary applicant name, address and country text with Alibaba Cloud Model Studio in Beijing, Mainland China. Manually entered goods and services are not sent to AI. If you choose AI classification and generate suggestions, the goods/services text you enter is sent to that service. Uploaded identity evidence, signed documents and file bytes are not sent to AI. The relevant notice appears before each preparation action. Use these actions only when your institution has authority for those purposes and locations; otherwise retain your draft and request team preparation. Results require review and do not establish professional acceptance.
Retention and historical pilots
Expired verification and unfinished registration records are cleared by the backend; sessions expire after seven days. Historical pilot records retain their approved cleanup schedule. Document retention and processing arrangements must be confirmed before private uploads are enabled. Accepted matter records, finance records and legal holds follow their applicable retention requirements. Provider backups and email logs follow the actual service plan and provider policy. Contact the desk for access, correction or deletion requests.
Email inquiries
Choosing an email link opens your email application. You decide whether to send. If you send an inquiry, Zhiquan IP receives the email and uses its contents to respond, assess the requested scope and discuss next steps. Your email service also processes the message under its own terms.
Keep the first inquiry non-confidential
Keep public inquiries and initial summaries non-confidential. In an enabled authenticated matter, upload only the requested documents to their correct purpose slots. Original files are not sent to public malware-sharing services or to AI for parsing. Platform receipt does not mean security checks have passed. Security clearance and email handoff do not establish signature validity, professional acceptance or an official filing. If uploads are unavailable, agree an alternative with peterlin@eastfiling.com before sending sensitive materials.
Your questions and requests
Contact the address above for questions about your inquiry or to request access, correction or deletion of information you have provided. Any applicable retention obligations will be explained when responding to your request. This website notice does not replace matter-specific engagement or document-processing terms.
