Privacy and terms
How we handle data, and the rules for using the sharing service.

Privacy policy
Who handles your information
Lanveris is operated by Shanghai Lancun Technology Co., Ltd. This policy covers sharing and reading files and work notes, associated accounts, Agent connections and website features. Contact contact@lancun.cc for privacy questions, rights requests or complaints.
We process necessary information on applicable legal grounds, including providing the service you request and meeting legal obligations. Where consent or separate consent is legally required, it must be obtained separately. Reading this page, installing a Skill or continuing to use the service does not substitute for legally required separate consent.
Accounts, verification codes and connections
Email sign-in uses your email address, verification result and login session to identify your account, keep you signed in and prevent impersonation. Codes are valid for 10 minutes. Sending the sign-in email requires an email service to process your address and the email content. Recipients do not need an account.
Sending without signing in creates a local connection identity; installation alone does not upload your work files. After you authorize an Agent, we retain its connection name, authorization status and usage times. Necessary credentials are stored locally and can be shared by Agents under the same operating-system user and service address. Other users or service addresses do not automatically share them. You can disconnect an Agent in My Lanveris or sign out from the Agent.
Content you choose to upload
When you create a share, we process the files you authorize, their names, sizes and content digests, the share title, work notes, expiry and access settings. This supports upload, storage, display, download, quota accounting and integrity verification. Installing the Skill does not by itself read or upload your entire computer, working directory or conversation history. Review the selected content before sending.
Submit only information needed for the share and ensure you have authority to handle any information about others. Sensitive personal information and children's information are subject to additional legal requirements; ordinary file-upload authorization does not replace them. Lanveris integrity verification is not a review of the content's legality or accuracy.
Share links and recipients
A share link carries access authority. Anyone or any Agent holding a valid link can read and download content under your access settings; a password is also required when you set one. Give links and passwords only to intended recipients. Private shares are not publicly listed, but forwarding a link can extend access to others.
When you give a link to another Agent, Agent or person, they process received content under their own settings, terms and privacy rules. Lanveris cannot remotely erase copies they have already obtained, and using an Agent does not automatically give Lanveris access to all of that Agent's data.
Service providers, storage and cross-border processing
Cloud hosting and object storage: the current service uses Alibaba Cloud servers and private object storage in Hong Kong, China, to process account information, shared content and operational data. Public website images, scripts and Skill packages are delivered through static asset services; private shared files are not published as public website assets. For users in mainland China, transferring personal information to Hong Kong is cross-border processing subject to applicable assessments and obligations.
Email delivery: processes the recipient address, verification email content and delivery status for the sign-in verification you request, rather than marketing emails. Timestamping: uses timestamp services from DigiCert, Sectigo or GlobalSign. We submit the share snapshot's digest, not the original files, work notes or login email; the provider also receives technical information needed for the network request.
We require service providers acting on our instructions to respect the agreed purposes, scope and security responsibilities. This general description does not replace any legally required notice identifying an overseas recipient, the processing scope and rights procedures, or separate consent. You may contact contact@lancun.cc with inquiries or rights requests about provider or cross-border processing.
Local storage, access records and security
The website uses necessary cookies or local storage to keep you signed in, verify access and remember your language. The client stores connection credentials so you do not have to sign in for every request. Clearing these records may sign you out or require verification again. Disconnecting an Agent does not close your account or automatically delete published shares.
We process request times, IP addresses, browser or client information, access results and necessary operation records for security, abuse prevention, troubleshooting and share-access statistics. This version of the sharing service and its public information pages do not load Google Analytics, Baidu Analytics or third-party browser monitoring scripts. We use transport encryption, access controls, credential protection and backups, but do not promise that any network system is absolutely secure.
Retention and deletion
Shared content is retained for its selected lifetime. Expiry or deletion stops new access and releases quota, with a 7-day backend recovery period. Recovery requires sufficient quota and creates a new link; the old link stays invalid. Backend cleanup follows the recovery period. The same file, if still referenced by another valid share, remains subject to that share's retention period.
Disaster-recovery backups are cleaned up according to their group deadlines; each backup snapshot is retained for at most 7 days and is not a permanent archive. Login email and account association records are retained to maintain the account and are deleted or anonymized as legally required after an account-closure request is processed. Verification codes and temporary access credentials expire on their respective schedules; expiry does not mean that all security records are erased at the same time.
Security logs, complaint records and records subject to legal retention are retained only for the periods needed for security, legal obligations or a specific dispute. They are deleted or anonymized when that period ends or their purpose no longer requires them. Where a legal retention period has not ended or deletion is temporarily technically infeasible, processing is restricted to storage and necessary security protection.
Limits of download revocation and deletion
After link access is revoked, a password is set, a share is deleted or it expires, new access is checked against the updated state. A previously issued temporary file-download URL may remain valid for up to 60 seconds, and an already-started transfer may finish. Files downloaded to a recipient's device and exported proofs cannot be remotely recalled by changing the link.
Access, correction, deletion and account closure
In My Lanveris you can view and manage your shares, download content, delete shares and disconnect Agents. To access or copy personal information, correct your email or other records, delete information, restrict processing, withdraw consent, request a legally available transfer or close your account, email contact@lancun.cc describing your request.
We will handle requests promptly and verify identity using information proportionate to the request to prevent impersonation; do not send passwords, Agent secrets or unrelated files. If we cannot lawfully fulfill a request, we will explain why and what alternatives are available. Withdrawing consent does not affect lawful processing based on consent before withdrawal, but features that depend on that processing may no longer be available. You may also complain to the competent authority or seek judicial remedies.
Children and sensitive information
This service is for handing off work files and is not directed specifically at children. Minors should use it with a guardian's guidance. Information about children under 14 requires guardian consent and special safeguards. There is currently no dedicated child-authorization flow; please do not upload such information through the general service. If a child's information was submitted without authorization, contact contact@lancun.cc so we can investigate and take appropriate action.
Do not submit identity documents, health information, financial account details, precise location or other sensitive personal information unrelated to the purpose of a share. Where such processing is genuinely necessary, establish necessity, obtain applicable authority or consent and implement additional safeguards before submission. An ordinary share link does not establish that these requirements have been met.
Security incidents and policy changes
If a security incident may affect your rights, we will take remedial measures and notify affected users and authorities as required by applicable law. Material policy changes will be highlighted on the website or through another appropriate channel. Updating this page alone does not replace renewed consent where the law requires it.
Terms of service
What the service provides
Lanveris creates a fixed share of selected files and work notes for recipients to read and download in a browser or their own Agent. It is not runtime hosting, unlimited cloud storage or a permanent archive. Keep independent copies of important files. Previously issued legacy proofs remain subject to their original proof rules and are not automatically invalidated by use of the new file-sharing service.
Accounts and authorization
Use an email address you are entitled to use and protect your email, devices and credentials. Authorized Agents can share and manage content within their authority; other installed Skills on the same machine may reuse the connection. Use separate operating-system users on a shared computer. If a connection is misused, disconnect it and contact us promptly. Signing out of one interface does not necessarily end every other Agent or browser session.
Content rights and necessary permission
You retain your existing rights in submitted content. To provide the share you request, you permit us to store, copy, transmit, display and verify it only to the extent and for the period necessary for the service. This does not transfer ownership to us or automatically permit recipients to modify, commercially exploit or redistribute it. Ensure you hold the rights needed to submit and provide the content to intended recipients, including lawful handling of personal information, trade secrets and third-party materials.
Free quotas and expiry
The current basic service is free. Without sign-in, a local connection has 500 MB total capacity, with up to 200 MB and 7 days per share. After email sign-in, the account has 10 GB shared across its computers, with up to 3 calendar months per share. A signed-in share can use the remaining account quota; it does not receive an additional 10 GB. Work notes and necessary manifests also count toward the quota. Available capacity is shown in the service and checked when sending.
Reasonable request-rate or concurrency limits may apply to uploads, downloads and other operations to maintain availability. If free-service rules change or paid services are introduced, we will explain their scope and prices in advance. This provision does not authorize automatic charges or retroactively charge for existing free operations.
Expiry, deletion and recovery
An expired or deleted share stops being accessible and releases quota, with a 7-day backend recovery period for its owner. Recovery requires sufficient quota and creates a new share link and proof; the original link does not revive. After the recovery period, do not rely on the service to recover the content. Access termination and physical backend cleanup do not occur at the same instant; see the privacy policy for details.
Link access and recipient control
People or tools holding a valid share link and any required password can obtain the content, so forward it with care. Changing access settings does not retrieve content already downloaded. Previously issued download URLs can remain usable for up to 60 seconds, and transfers already underway may finish. Before sending content to a third-party Agent, understand its data-use rules and obtain any necessary authorization.
What proofs and verification establish
A proof supports verification of a fixed share's digest and timestamp. Successful verification means the checked content matches its corresponding record and the relevant signature checks pass. It does not establish authorship, copyright ownership, factual truth or contractual validity, and does not guarantee acceptance in every dispute. If you change local files, share them again; the original proof does not cover the new content.
Acceptable use and enforcement
Do not use the service to infringe others' rights, distribute unlawful content or malware, steal credentials, bypass access controls, deliberately exhaust resources or transmit information prohibited by law. We may take necessary measures proportionate to a specific risk, such as limiting access, suspending a connection or addressing the affected content, and explain the reason where legally permitted and safe. Contact contact@lancun.cc to appeal an error; rights holders can provide the information needed to request action on infringing content.
Availability and responsibility
Maintenance, network problems or third-party outages may temporarily affect availability. We will take reasonable measures to operate the service and resolve faults, with advance notice of significant planned changes where practicable. Keep your original files and do not use this service as your only backup.
Each party is responsible as required by applicable law and according to its fault. These terms do not exclude or limit liability that cannot lawfully be excluded or limited, including liability for personal injury or property loss caused intentionally or by gross negligence. They do not reduce statutory consumer or personal-information rights.
Changes, termination and disputes
You may stop using the service, disconnect Agents and request account closure under the privacy policy. For material changes to these terms or a planned service shutdown, we will provide notice on the website or through another appropriate channel and make reasonable arrangements for content export or further handling. Changes requiring consent will obtain it separately and will not retroactively remove accrued lawful rights.
The service is governed by the laws of the People's Republic of China, without excluding mandatory protections that apply to you. You may first seek resolution through contact@lancun.cc. If no resolution is reached, either party may bring proceedings before a court with jurisdiction under applicable law. The Chinese and English texts are intended to be consistent; language differences do not reduce your statutory rights.
