5. Shopify

Our store is hosted by Shopify.

Shopify processes personal information relating to your use of our online store in order to provide its e-commerce platform and related services.

Information may therefore be transmitted to or processed by Shopify and its service providers in countries other than your country of residence.

For more information about Shopify’s processing practices, please review Shopify’s applicable privacy notices.

6. Cookies, Analytics, and Advertising

We and our service providers may use cookies and similar technologies to operate the website, remember preferences, maintain security, understand website usage, measure performance, and, where permitted, provide or measure advertising.

Depending on your location and the services enabled on our website, certain disclosures of personal information for targeted advertising may be treated as a “sale,” “sharing,” or targeted advertising under applicable U.S. state privacy laws even where no money is exchanged for personal information.

Where required by applicable law, eligible users may opt out through privacy controls made available on our website or by contacting us.

We will also process recognized browser-based opt-out preference signals where required by applicable law and supported by our systems.

7. Marketing Communications

If you receive promotional emails from us, you may unsubscribe at any time using the unsubscribe link in the email.

Even if you unsubscribe from marketing messages, we may continue to send non-promotional communications relating to orders, payments, returns, accounts, security, or customer service.

8. Retention

We retain personal information only for as long as reasonably necessary for the purposes described in this Privacy Policy, including fulfilling orders, maintaining business and tax records, resolving disputes, preventing fraud, and satisfying legal obligations.

Retention periods may vary depending on the type of information and applicable legal requirements.

9. Security

We use reasonable administrative, technical, and organizational safeguards designed to protect personal information.

However, no website, network, storage system, or method of transmission is completely secure, and we cannot guarantee absolute security.

10. Your Privacy Rights

Depending on where you live, you may have rights relating to your personal information, including the right to request access, correction, deletion, or a copy of certain personal information.

You may also have the right to opt out of certain targeted advertising, sale, or sharing of personal information, or to appeal certain privacy decisions.

These rights are subject to applicable law and may not apply in every circumstance.

We may need to verify your identity before processing a privacy request.

We will not unlawfully discriminate against you for exercising an applicable privacy right.

Our online store is intended for a general audience and is not directed to children.

We do not knowingly collect personal information from children in violation of applicable law.

If you believe that a child has provided personal information to us improperly, please contact us.
