Privacy Policy

Effective and Last Updated: September 19, 2026

This Privacy Policy explains how Avierl collects, uses, discloses, and protects personal information when you visit https://www.avierl.com, browse or purchase products, create an account, contact customer service, subscribe to communications, interact with our advertisements, or otherwise use our services.

Avierl is operated by HONG KONG KAICHEN INTERNATIONAL LIMITED. For applicable privacy laws, HONG KONG KAICHEN INTERNATIONAL LIMITED is the data controller or business responsible for the personal information described here, except where an independent third party determines its own purposes and means of processing.

1. Personal Information We Collect

Depending on how you interact with Avierl, we may collect:

Identifiers and contact details, such as name, email address, telephone number, billing address, and shipping address.
Account and order information, including products viewed, selected, purchased, returned, or refunded.
Payment and transaction details processed by payment providers. We do not independently store complete payment card numbers submitted directly to those providers.
Customer service communications, product questions, return information, and feedback you choose to provide.
Device and usage information, such as IP address, browser type, device identifiers, cookie identifiers, referring pages, pages viewed, interactions, and approximate location derived from IP address.
Marketing preferences, consent choices, and opt-out signals.

2. How We Collect Information

We collect information directly from you, automatically through the website and similar technologies, and from service providers involved in ecommerce, payment, fraud prevention, fulfillment, shipping, analytics, attribution, advertising, and customer support.

3. How We Use Information

We use personal information to:

Provide products, process payments, fulfill orders, arrange delivery, and manage returns or refunds.
Communicate about orders, service requests, policy changes, or security matters.
Operate, maintain, personalize, measure, and improve the website and product presentation.
Detect fraud, abuse, security incidents, and other unlawful activity.
Comply with legal, tax, accounting, regulatory, and contractual obligations.
Send marketing communications where permitted and measure advertising performance.

4. Legal Bases

Where a legal basis is required, processing may rely on performance of a contract, compliance with law, our legitimate interests, protection of rights and security, or your consent. You may withdraw consent where processing depends on consent, without affecting earlier lawful processing.

5. How We Disclose Information

We may disclose personal information to service providers and partners that help us operate the store, including Shopify, payment processors, fraud-prevention providers, fulfillment and logistics providers, carriers, customer-service systems, analytics providers, professional advisers, and advertising or attribution partners. We may also disclose information to comply with law, respond to lawful requests, protect rights or safety, or complete a corporate transaction.

Shopify powers our online store and processes information as described in its own privacy materials. Payment, carrier, analytics, and other independent providers may also apply their own privacy notices.

6. AppLovin and Advertising Technologies

We may use AppLovin as an advertising and measurement partner. If AppLovin advertising technologies, pixels, cookies, scripts, or similar tools are enabled, AppLovin may receive device, browser, cookie, IP address, advertisement interaction, attribution, and purchase-event information for advertising delivery, measurement, fraud prevention, reporting, and improvement of its services, subject to applicable law and consent requirements.

We do not intentionally send AppLovin sensitive personal information, protected health information, complete payment card details, account passwords, private communications, or information that we know relates to a child.

7. Cookies and Consent Choices

We and our providers may use cookies, pixels, tags, local storage, and similar technologies for essential store functions, security, preferences, analytics, attribution, and advertising. Where required, non-essential technologies are used only after an appropriate consent choice.

You may use the cookie banner shown in applicable regions to accept, reject non-essential technologies, or manage preferences. You may also visit Your Privacy Choices. We honor legally required browser-based privacy signals, including Global Privacy Control and other applicable opt-out signals.

8. Marketing Choices

You may unsubscribe from marketing email using the link in the message or by contacting us. Service messages about an order or security may still be sent when necessary.

9. Data Retention

We retain personal information only as long as reasonably necessary for the purposes described here, including providing services, maintaining transaction records, resolving disputes, enforcing agreements, and meeting legal obligations. Order and accounting records may generally be retained for up to 7 years where needed. Other records are retained for shorter periods based on operational need, consent, and provider configuration.

10. International Data Transfers

Our service providers may process information in locations outside your country. Where required, we use recognized safeguards or other lawful transfer mechanisms. Privacy protections can differ between jurisdictions.

11. Security

We use reasonable administrative, technical, and organizational safeguards designed to protect personal information. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

12. Your Privacy Rights

Depending on your location, you may have rights to request access, correction, deletion, portability, restriction, objection, withdrawal of consent, or an opt-out from targeted advertising, sale, or sharing. You may also have the right to appeal a decision or contact a privacy regulator.

To submit a request, email support@avierl.com. We may verify your identity before completing a request. Authorized agents may be required to provide evidence of authority. We will not unlawfully discriminate against you for exercising a privacy right.
