01 Scope & operator
上海代数律动技术有限公司, operating under the AlgoTech brand ("we"), operates this website. This policy explains how personal information is handled when you browse the website, download installers, use our account and related online project services, or contact support. It also applies when you access these online services through AlgoSLAM or AlgoStudio.
You do not need an account to browse product information, support guidance or public download information. Account authentication, project uploads and support requests each process information for the features you choose to use. For features you choose that involve additional processing, we explain its purpose and scope before use and obtain any authorization required by applicable law.
For personal-information inquiries or requests, contact sales@algoslam.com.
02 Information handling
Website visits & downloads
Website and download services process connection information such as IP addresses, request times, requested paths, browser request information and response statuses to deliver pages and files, diagnose faults, maintain service security, and analyze page popularity, referring websites, device types and transferred bytes. Analytics runs offline on our server without additional browser tracking scripts, analytics cookies or persistent visitor identifiers. Analytics logs exclude query strings, cookies, request bodies and full referring-page paths. Public software downloads do not require an account, phone number or email address.
Accounts & authentication
When you register, sign in or recover an account, the account service processes the username and password authentication information you submit, the email address or phone number used for your chosen method, verification codes, login sessions and related security records. This supports identification, authentication, abuse prevention and access control. Registration forms distinguish required and optional information.
Online project services
When you choose to upload, download, share or request processing of a project, the service processes account, workspace and project identifiers, file names, sizes, checksums, submitted file contents and relevant operation records. This supports transfer, storage, access control and the processing you request. Trajectories, location data and imagery in project files may contain personal information. Please ensure that you have the necessary authorization and remove information unrelated to the service before submitting files.
Inquiries & technical support
When you contact us, we process the contact details, issue descriptions, device and software versions, screenshots, logs or project samples you provide to respond and investigate the issue. Submit only the material needed for support, without passwords, verification codes, access tokens or unrelated personal information.
03 Website features & third parties
When you select a language, this website stores only the language code (zh-CN or en) in your browser’s localStorage under algotech.language. This preference is not sent to our server and is used to remember your home-page language. You can remove it by clearing this website’s data in your browser settings.
Email links open the email application configured on your device. The copy-email button writes our contact address to your clipboard without reading its existing contents. Account services use necessary cookies and session information to maintain sign-in and validate requests. You can clear cookies in your browser settings; affected services may then require you to sign in again.
When you choose verification-code authentication, SMS or email delivery services process the destination number or address, verification message and delivery result to complete the authentication you requested. Emails you send are also handled by your chosen email providers under their service rules. External links, including the MIIT filing enquiry service, lead to websites governed by their own information-handling rules.
Where we engage service providers to process personal information, we define the purpose, information scope and protection requirements appropriate to the service. Providing information to another independent controller, or transferring personal information outside China, requires the notices, consents and other procedures applicable to that processing.
04 Retention & security
Raw website analytics logs are retained for 90 days based on archive dates. Aggregate monthly reports are retained for 12 calendar months including the current month. Scheduled tasks remove expired files. Monthly reports exclude individual visitor IP addresses, and logs and reports are restricted to authorized internal personnel. Other security and operation records are managed separately for their respective purposes.
Files on your device and files uploaded to online services are managed separately. Account information is retained for the period needed to provide account services. Project files are handled according to storage and deletion actions by you or authorized workspace managers and the applicable service arrangements. Support materials are used while resolving the issue and for necessary follow-up. Security and operation records are retained for the periods needed to maintain security and meet legal obligations.
We delete or anonymize personal information when its retention period ends, its purpose has been fulfilled or deletion is otherwise required by law. If a statutory retention period has not expired or immediate deletion is technically impracticable, further processing is limited to storage and necessary security protection. Account closure and deletion of project materials require separate consideration; uninstalling an application does not automatically delete server-side accounts or files.
We use measures such as HTTPS access, identity and permission checks, session management and operation records to protect online services. Keep your account credentials secure and contact the email address in this policy if you notice unusual sign-ins, information exposure or other security issues.
05 Your choices & contact
You may request access to or copies of your personal information, correction, completion or deletion, withdraw consent-based authorization, or request account closure as provided by applicable law. Email sales@algoslam.com with the subject "Personal information request", identifying the account or service, your request and a way to contact you.
To protect your account and other people's information, we verify identity in a manner appropriate to the request and communicate its scope and outcome. Do not send passwords or verification codes. If a request cannot lawfully be fulfilled, we explain why. Requests involving team workspaces or shared projects also require verification of authority and consideration of other members.
You can manage cookies and granted permissions in your browser or operating-system settings. Withdrawing authorization necessary for a particular feature may prevent that feature from being provided. Withdrawal does not affect processing lawfully performed beforehand.
06 Minors & policy updates
Our products and related services primarily support surveying, engineering and professional technical work. Minors should review this policy with a guardian. When processing personal information of children under fourteen, we obtain guardian consent and apply appropriate safeguards under applicable law. Guardians can use the email address above to request access, correction or deletion.
We update this policy as services or applicable requirements change, showing the version and update date on this page. Material changes to processing purposes, information scope or other important matters will be communicated appropriately. Where renewed consent is required by law, we obtain it. This policy takes effect on publication.
