No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. All of the above categories exclude text messaging originator opt-in data and consent; this information will not be shared with any third parties.

4. Cookies and Tracking Technologies

Cookies are small text files placed on your device when you visit our Site. We use the following types of cookies:

• Essential cookies: Required for the Site to function, including shopping cart functionality, checkout, and security features. These cannot be disabled.
• Analytics cookies: Help us understand how visitors interact with our Site (Google Analytics, Shopify Analytics).
• Advertising cookies: Used to deliver relevant advertisements and measure campaign performance (Meta Pixel).

Managing cookies: You can control cookies through your browser settings. Most browsers allow you to block or delete cookies. However, disabling essential cookies may prevent you from using certain features of our Site, including making purchases. You can also opt out of specific tracking services using the links provided in Section 1 above.

Global Privacy Control and Do Not Track. Some browsers and extensions can transmit an opt-out preference signal, such as Global Privacy Control (GPC). Where required by applicable law, we treat a GPC signal as a valid request to opt out of the sale or sharing of personal information for that browser. There is currently no common industry standard for responding to "Do Not Track" browser signals, and we do not respond to them separately.

5. Data Retention

We retain your personal information for as long as necessary to fulfill the purposes described in this policy, including:

• Order records: Retained for a minimum of seven (7) years for tax and accounting compliance
• Account and contact information: Retained as long as your account is active or as needed to provide you with services
• Marketing preferences and consent records: Retained until you unsubscribe or request deletion, and thereafter as needed to honor your opt-out and to evidence consent
• Analytics data: Retained in accordance with each analytics provider's data retention policies

When your information is no longer needed, we will securely delete or anonymize it.

6. Your Rights and Choices

Depending on where you live, you may have some or all of the rights listed below. These rights are not absolute, may apply only in certain circumstances, and in certain cases we may decline a request as permitted by law.

In accordance with applicable law, you may designate an authorized agent to make a request on your behalf; we will require proof that you authorized the agent, and we may need to verify your identity directly with you.

Our Site uses SSL/TLS encryption to secure data transmitted between your browser and our servers.

While we strive to protect your personal information, no method of transmission over the Internet or electronic storage is completely secure. We cannot guarantee absolute security.

As of the Last Updated date of this Privacy Policy, we do not have actual knowledge that we "share" or "sell" (as those terms are defined in applicable law) the personal information of individuals under 16 years of age.

11. Third-Party Links

Our Site may contain links to third-party websites, including our social media pages on Instagram, Facebook, and YouTube. This Privacy Policy applies only to our Site.
