Privacy Policy

Information Collection and Use

We collect several different types of information for various purposes to provide and improve our Service to you.

Types of Data Collected

Personal Data

While using our Site, we may ask you to provide us with certain personally identifiable information that can be used to contact or identify you ("Personal Data"). Personally identifiable information may include, but is not limited to:

Email address and account data

When you create an account, we store the email address you provide, an email-normalized version used to prevent duplicate accounts, account creation and verification dates, and any optional basic profile information you later provide. Passwords are processed as one-way Argon2id password hashes; we do not store plaintext passwords.

Account Security and Transactional Email

We store hashed session identifiers, security-token hashes, expiration and revocation dates, and rate-limit/security records derived from keyed hashes of network and account identifiers. We use this information to sign users in, verify email ownership, reset passwords, prevent abuse, and send account verification and security notifications. These messages are transactional account messages and are not marketing subscriptions.

Partnership and Business Inquiries

When you submit a partnership inquiry, we collect the name, business email address, contact number, company or organization, optional job title, partnership interest, estimated unit requirements, and timeline you provide. We use this information to evaluate and respond to the inquiry, maintain a record of the business relationship, prevent form abuse, and send a transactional confirmation that the inquiry was received. The confirmation is not a marketing subscription.

Partnership inquiries are stored in our MySQL database and included in encrypted operational backups. Access is limited to personnel and systems that need the information to respond, administer the Site, or protect it from abuse. Inquiry records are retained for a reasonable business, security, backup, dispute, and legal period, then reviewed or deleted according to the operator's approved retention schedule.

WhatsApp Communications and AI-Assisted Customer Support

When you contact LANGFEITE through WhatsApp, we may collect and process information associated with your communication, including your phone number, WhatsApp profile information made available to us, message content, order information, product information, customer service requests, and any photos, videos, documents, or other information you choose to provide.

We use this information to respond to inquiries, provide product information and recommendations, assist with orders and payment-related inquiries, provide shipping and after-sales support, process return or warranty requests, prevent fraud and abuse, maintain customer service records, and improve the quality and efficiency of our customer support operations.

We may use automated systems, including artificial intelligence (“AI”), to assist with customer service. These systems may help us understand customer inquiries, retrieve relevant product or order information, prepare or provide responses, classify requests, and determine when a conversation should be transferred to a human representative.

AI-assisted customer support is part of our customer service operations. You may request assistance from a human representative when human review or intervention is appropriate.

To provide WhatsApp customer support, information may be processed through WhatsApp and Meta infrastructure and by service providers that support our hosting, communications, security, customer service, and AI-assisted processing. These service providers may process information on our behalf only as necessary to provide their services and subject to applicable contractual and security requirements.

We do not sell WhatsApp conversation data. We do not authorize WhatsApp conversation data to be used by our AI service providers to train or improve general-purpose AI models.

Please avoid sending sensitive personal information through WhatsApp unless it is reasonably necessary for us to provide the service or support you requested.

Hosting and Service Providers

Account data is processed using Hostinger hosting, MySQL database, and SMTP email services. These providers process data as needed to host the Site, maintain account sessions, and deliver account email.

We use hCaptcha on password-reset requests to distinguish legitimate users from automated abuse. The hCaptcha widget may process network, device, browser, and interaction information for this security purpose under the hCaptcha Privacy Policyand Terms of Service.

When you communicate with us through WhatsApp, your communications may also be processed through WhatsApp and Meta infrastructure. We may use customer service platforms, hosting providers, and AI service providers to assist in processing and responding to customer inquiries. These providers process information on our behalf for purposes such as message delivery, customer support, security, automation, and AI-assisted response generation.

Retention

Account records are retained while an account remains active and for a reasonable period needed for security, dispute, backup, and legal purposes. Login sessions expire after inactivity or their absolute lifetime and may be retained briefly after revocation for security cleanup. Email-verification links expire after 24 hours and password-reset links after 30 minutes; consumed or expired token records and rate-limit records are periodically deleted. Backup retention periods depend on the hosting configuration.

Customer service communications, including WhatsApp conversations and related support records, may be retained for a reasonable period as necessary to provide customer support, maintain order and service history, prevent fraud and abuse, resolve disputes, comply with applicable legal obligations, and protect our legitimate business interests. Retention periods may vary depending on the nature of the communication and applicable operational or legal requirements.

Account Cookies

We use a strictly necessary, HttpOnly session cookie to keep an account signed in and a separate security cookie to protect account-changing requests from cross-site request forgery. These cookies are not used for advertising and do not contain a password or complete user profile.

Deletion and Data Requests

You may request deletion of your account or related personal data through the Site's existing contact page. You may also contact us regarding access, correction, or deletion of personal information associated with customer service communications, including WhatsApp communications. Some records may need to be retained for security, fraud prevention, dispute resolution, backup, or applicable legal obligations.
