Who we share it with
We do not sell your personal information for money. We share it only with service providers that help us run the business, such as our e-commerce platform (Shopify), payment processors, shipping carriers, email and SMS providers, and analytics and advertising partners. We may also share information if required by law, to protect our rights, or as part of a merger or sale of the business.
Cookies and advertising
We and our partners use cookies and pixels for things like keeping your cart, analytics, and showing you relevant ads on other sites. You can block or delete cookies in your browser settings, though some site features may stop working. You can also opt out of interest-based ads at optout.aboutads.info.
Email and text messages
You can unsubscribe from marketing emails at any time with the link at the bottom of any email. If you sign up for texts, reply STOP to opt out. Message and data rates may apply. Signing up for texts is never required to make a purchase.
Your privacy rights
Depending on where you live (for example, California, Colorado, Connecticut, Virginia and other US states), you may have the right to access, correct or delete your personal information, to opt out of targeted advertising or the "sale" or "sharing" of personal information as those terms are defined by law, and not to be discriminated against for using these rights. To make a request, email info@optimumefx.com. We may need to verify your identity, and we'll respond within the time required by law.
Data retention
We keep personal information for as long as needed to provide our services, keep business and tax records, resolve disputes, and meet legal requirements.
Security
We use reasonable safeguards to protect your information, including encrypted checkout. No method of storage or transmission is 100% secure.
