Privacy Policy

Langyan Growth refers to the website, software workspace, account authorization workflow, content operations tools, APIs, support channels, and related services legally operated under the Langyan Growth brand.

We understand the importance of personal information and connected account data. This Privacy Policy explains how we collect, use, store, transfer, disclose, and protect information when you visit our website, request access, use the workspace, connect TikTok accounts, submit content tasks, contact support, or otherwise use Langyan Growth.

Except for information necessary to provide core functions, maintain security, or comply with legal requirements, you may choose not to provide certain information. If you refuse or withdraw authorization, some corresponding functions may be unavailable.

Account and access information: when you request access, register, log in, or communicate with us, we may collect your name, work email, company, role, intended use case, message, account identifier, login credentials, workspace role, and other information needed to create and manage your account.

TikTok authorization information: when you authorize a TikTok account through Langyan Growth, we may process information approved by you and TikTok, such as account profile information, public video metadata, authorized scopes, publishing task metadata, access tokens, refresh tokens, token status, and account connection records. We use this information only to provide authorized account connection, publishing workflows, display context, support, security, and data request paths.

Content and workspace information: when you use content planning, account grouping, review, scheduled publishing, publishing coordination, or data visibility features, we may process content titles, descriptions, files or links you submit, publishing settings, review status, task logs, team member actions, connected account context, and related operational records.

Order, subscription, and support information: if you purchase or apply for paid services, we or our service providers may process order records, plan information, billing contact details, payment status, invoices, support tickets, consultation records, and communication details necessary to provide service and respond to requests.

Security and technical information: to keep the service stable and secure, we may collect device type, browser type, operating system, IP address, network status, access time, pages visited, feature usage, crash records, error logs, audit logs, and other technical information reasonably necessary for authentication, troubleshooting, abuse prevention, and service improvement.

We may use cookies, local storage, pixels, or similar technologies to keep you signed in, remember preferences, secure sessions, understand website performance, improve response speed, analyze usage, and support customer service.

You can manage or clear cookies through your browser settings. If you disable cookies or similar technologies, some login, security, form, or preference functions may not work properly.

We process information to perform or prepare a service contract with you, provide requested functions, obtain your consent where required, comply with laws and platform obligations, protect security, prevent misuse, resolve disputes, and pursue legitimate business interests that do not override your rights.

Where permitted by applicable law, we may process information without separate consent when it is necessary for contract performance, legal obligations, public safety, emergency protection of life or property, handling information you have lawfully made public, or other circumstances allowed by law.

We follow principles of legality, legitimacy, necessity, security, and minimum scope when working with service providers or partners. Partners may include hosting providers, analytics providers, customer support tools, payment or billing providers, security vendors, email delivery providers, and TikTok developer platform services.

For entrusted processing, we require service providers to process information only for agreed purposes and to protect information through appropriate contractual and technical measures. For joint or independent processing scenarios, each party is responsible for complying with applicable data protection obligations.

We do not sell personal information. We may share, transfer, or disclose information when necessary to provide the service, complete transactions, comply with law, respond to lawful requests, protect rights and security, handle mergers or asset transfers, or with your separate consent. If we cease operating the service, we will stop collecting information and delete or anonymize relevant personal information as required by law.

You may request access, copy, correction, supplementation, deletion, restriction, account disconnection, authorization revocation support, or account closure by contacting us through the contact page. We will respond within a reasonable period and in accordance with applicable law.

If you withdraw TikTok authorization or request account disconnection, we will stop using the relevant authorized data for the disconnected functions, except where retention is required for security, legal compliance, dispute resolution, or platform obligations. Withdrawal does not affect processing completed before the withdrawal.

We use reasonable administrative, technical, and organizational safeguards to protect information against unauthorized access, leakage, alteration, loss, misuse, and destruction. These safeguards may include access controls, encryption or token protection, logging, permission management, security reviews, and incident response procedures.

We retain information only for the period necessary to provide services, fulfill the purposes described in this policy, resolve disputes, protect security, comply with laws, or meet platform requirements. When information is no longer needed, we will delete or anonymize it unless retention is legally required.

Langyan Growth is intended for business and professional use. We do not knowingly provide services directly to children. If you are under the age required by applicable law to consent to data processing or enter into a binding agreement, you may use the service only with consent and supervision from a parent, legal guardian, or authorized organization.

We may update this Privacy Policy because of product changes, legal requirements, security needs, or operational adjustments. The updated version will be posted on our website with an effective date. For material changes, we will provide notice where required by law.

If you have questions, complaints, account disconnection requests, TikTok authorization requests, or data deletion requests, please contact us through the contact page on the Langyan Growth website.
