Privacy Policy

The effective date of this Privacy Policy is May 8, 2023.

Stacker, LLC. (“we”, “us”, “our”, “Stacker”) is committed to protecting and respecting the privacy of our Users (“you”, “your”, “customers”, “User”, “Users”). In the Stacker Privacy Policy, we describe what types of data we collect, how we use this data, how we protect your data, and the rights and choices you have as a User regarding data collection. In essence, respecting your privacy is fairly simple; we do not use third-party advertising companies; we will not sell your data; and we use reasonable security measures to protect your data.

Stacker is based in the United States of America and is subject to U.S. federal and Minnesota state laws. If you are accessing our website or services from other jurisdictions, please be advised that you are transferring your personal information to us in the United States, and by using our website or services, you consent to that transfer and use of your personal information in accordance with this Privacy Policy. You also agree to abide by the applicable state and U.S. federal laws or regulations governing the use of the Internet, including personal data collection, use, and disclosure which may be different from those in your jurisdiction. If the use of our website or services would be unlawful in your jurisdiction, please do not access our website.

By using and accessing our website or services, and voluntarily submitting Personal Data, you consent and agree to the terms of this Privacy Policy.

Types of Information We Collect

We collect both Personal Data and non-personal data, such as Anonymous Data, about our Users (website users and customers). “Personal Data” means data that you voluntarily submit to Stacker allowing us to identify or contact you.

Anonymous Data does not typically permit the identification of individual persons, and typically consists of passively collected information about your activities on our website, through our software, or through our Services (which includes any communication/interaction between you and Stacker). Anonymous Data may include data about your printer, computer, visits to the website, your geographic location, browser type, referral source, length of visit, and pages viewed.

How We Use Information

We use your Personal Data and Anonymous Data to provide services, to improve our website and services, to track movement around the website, and to protect Stacker and our Users. Personal Data may be used to respond to your requests and to offer more personally tailored content and services. For example, some of the Personal Data we collect may be used so that when you visit our website or use our Services again, you will be recognized, and we could provide you more relevant content suggestions, customized search results, or other information appropriate to your interests.

Also, if you provide your mailing address or email address to Stacker, the address may be used to send you notices of a transactional, administrative, or relationship nature or as required by law, such as notification of a material change in this Privacy Policy, notification of an actual or suspected security breach that affects your information stored by or for Stacker, public relations announcements, etc.

Information on how to request this deletion can be found in the “Your Rights and Opt-Out Choices” section.

Information Disclosure and Third Parties

Except as set forth below, Stacker will never knowingly disclose your Personal Data to a third party.

Service Providers

Stacker may disclose Personal Data and non-personal data to our outside vendors and contractors (collectively known as “Service Providers”) who need to access such information in order to perform services (including, without limitation, transaction/payment processing, order fulfillment, data research and analysis, data collection and processing, data storage, data security, hosting and technical support, as well as marketing and advertising support) for us. Stacker requires that our Service Providers use your information shared by Stacker solely for the purposes of performing specific services for Stacker and that they maintain the confidentiality, security, and integrity of such information and not further disclose the information to others. Information collected by these Service Providers or integrated services is also subject to their own terms and policies.

Other Reasons for Disclosure

Regardless of any choices you make regarding your Personal Data (as described in this Privacy Policy), Stacker may disclose Personal Data if it believes in good faith that such disclosure is necessary (a) in connection with any legal investigation; (b) to comply with relevant laws or legal processes, including subpoenas, warrants, or court orders served on Stacker; (c) to cooperate with law enforcement; (d) to respond to an emergency; (e) to protect or defend the rights or property of Stacker, our Users, or the public; or (f) to investigate or assist in preventing any violation or potential violation of the law or this Privacy Policy. In addition, Stacker may transfer Personal Data and non-personal data as part of our assets if Stacker (or parts of our business) are sold or transferred to, merged with, or acquired by, a third party. Upon such transfer, the privacy policy of the acquiring entity may govern the further use of your information.

Links to Third Party Websites

Stacker’s website, email communication, and other online resources, may contain links to other websites. Stacker urges that when you go to another site, you should read the privacy statements included there. This Privacy Policy applies only to your interactions with Stacker. We have no control over, do not review, and cannot be responsible for non-Stacker websites or their content.

Social Media

We may use hyperlinks on our website, email communication, and other online resources that will redirect you to a social network if you click on the respective link. When you click on a social network’s plugin, such as Facebook’s “Like” button or Twitter’s “tweet” button, that particular social network’s plugin will be activated, and your browser will be directly connected to that provider’s servers. If you do not use these buttons, none of your data will be sent to the respective social network’s plugin provider. So for example, when you click on Facebook’s “Like” button on our website, Facebook may receive your IP address, location, browser version, screen resolution, and operating system on the device you have used to access our website. Settings regarding privacy protection can be found on the websites of these social networks and are not under our control.

Your Rights and Opt-Out Choices

Providing Personal Data is voluntary, but failing to share Personal Data may prevent you from completing an order, requesting User assistance, or accessing other Services offered by Stacker.

Data and Opt-Out Rights

If you provide us with your Personal Data, you have the following rights with respect to that information: (a) to review the User information that you have supplied to us; (b) to request that we correct any errors, outdated information, or omissions in User information that you have supplied to us; (c) to request that your user information not be used to contact you; (d) to request that your User information be removed from any solicitation list that we use; (e) to make a complaint; (f) to request that your Personal Data be deleted from our contacts; (G) to request a restriction of, or withdraw your consent for, the use of your Personal Data.

To exercise any of these rights, please contact us at We will change, correct, or delete your information as soon as possible. Deleting data means that Stacker will properly and completely dispose of it (in its digital and/or physical form). In other words, it will be destroyed or otherwise disposed of in a manner that protects against loss, misuse and unauthorized access, disclosure, alteration, and destruction.

Unsubscribing from Emails

You may unsubscribe from our marketing and promotional communication email lists by clicking on the “unsubscribe” link located on the bottom of our emails or by sending an email to NOTE, unsubscribing from promotional emails will NOT stop email communications from Stacker relating to your activities with Stacker, of a transactional, administrative or relationship nature, or as required by law, such as notification of a material change in this Privacy Policy, notification of an actual or suspected security breach that affects your Personal Data stored by or for Stacker, or special safety information related to your purchases from Stacker.

Do-Not-Track Policy

Most web browsers and some mobile operating systems include a Do-Not-Track (“DNT”) feature or setting that you can activate to signal your privacy preference not to have data about your online browsing activities monitored and collected. Because there is not yet a common understanding of how to interpret the DNT signal, our website currently does not respond to DNT browser signals or mechanisms.

Data Security

Protecting the security of the Personal Data that you share with Stacker is of the utmost importance to us. Your information is stored in a secured environment which is only accessible by key Stacker personnel.

Sensitive Personal Data/Credit Cards

When sensitive Personal Data (such as Customer Payment Information which typically includes your name, billing address, credit card/debit card information, and telephone number) is collected in our store, it is protected and processed by a third party processor through a secure connection. Stacker is not responsible for customer payment processing. Unless you choose to share your sensitive Personal Data over the telephone, by mailing a letter, or via electronic communication with Stacker, we do not save, have access to, or maintain direct control over any Customer Payment Information. Whenever credt/debit card information is shared with Stacker to place an order, the information is immediately destroyed by Stacker after it has been used to process your order.

Social Security Numbers

We will not typically request a customer’s Social Security number (SSN). However, if this information is requested for business or tax purposes, we will use the information solely for the designated purpose. We do not store the SSNs of our employees, partners, vendors, or customers electronically. In the same way that we treat all Personal Data, we will not disclose a SSN to anyone in ways inconsistent with this Privacy Policy or with applicable laws, and SSNs are accessible to only key personnel who use the information to provide services you have requested.

Company/Customer Relationship

By providing your email address to Stacker (whether through the Stacker website or otherwise), you acknowledge and agree that Stacker may notify you by email in the event of a breach of security involving your Personal Data. No method of transmission over the Internet, or method of electronic storage, is 100% secure. Although we strive to protect your data, Stacker assumes no responsibility or liability for damages incurred by unauthorized access to your Personal Data. If you have reason to believe that your Personal Data has been compromised, please contact us immediately at .

Protecting Children

We do not knowingly collect or maintain Personal Data from anyone under the age of 18, unless or except as permitted by law. If we learn that Personal Data has been collected from a User under 18 years of age through our website or Services, then we will take the appropriate steps to delete this information. If you are the parent or legal guardian of a child under 18 who has used our Services or has otherwise transferred Personal Data to the website, please contact Stacker using our contact information below to have that child’s account terminated and information deleted.

From time to time, we may update this Privacy Policy; therefore, you should periodically review this policy for changes.
