Questions or concerns? Reading this privacy notice will help you understand your privacy rights and choices. If you do not agree with our policies and practices, please do not use our Services. If you still have any questions or concerns, please contact us at [email protected].
In Short: We collect personal information that you provide to us.
We collect personal information that you voluntarily provide to us when you express an interest in obtaining information about us or our products and Services, when you participate in activities on the Services, or otherwise when you contact us.
The personal information that we collect depends on the context of your interactions with us and the Services, the choices you make, and the products and features you use. The personal information we collect may include the following:
We do not process sensitive information. All personal information that you provide to us must be true, complete, and accurate, and you must notify us of any changes to such personal information.
In Short: Some information — such as your Internet Protocol (IP) address and/or browser and device characteristics — is collected automatically when you visit our Services.
We automatically collect certain information when you visit, use, or navigate the Services. This information does not reveal your specific identity (like your name or contact information) but may include device and usage information, such as your IP address, browser and device characteristics, operating system, language preferences, referring URLs, device name, country, location, information about how and when you use our Services, and other technical information. This information is primarily needed to maintain the security and operation of our Services, and for our internal analytics and reporting purposes. Like many businesses, we also collect information through cookies and similar technologies.
The information we collect includes:
1. Log and Usage Data
Log and usage data is service-related, diagnostic, usage, and performance information our servers automatically collect when you access or use our Services and which we record in log files. Depending on how you interact with us, this log data may include your IP address, device information, browser type, and settings and information about your activity in the Services (such as the date/time stamps associated with your usage, pages and files viewed, searches, and other actions you take such as which features you use), device event information (such as system activity, error reports (sometimes called "crash dumps"), and hardware settings).
2. Device Data
We collect device data such as information about your computer, phone, tablet, or other device you use to access the Services. Depending on the device used, this device data may include information such as your IP address (or proxy server), device and application identification numbers, location, browser type, hardware model, Internet service provider and/or mobile carrier, operating system, and system configuration information.
3. Location Data
We collect location data such as information about your device's location, which can be either precise or imprecise. How much information we collect depends on the type and settings of the device you use to access the Services. For example, we may use GPS and other technologies to collect geolocation data that tells us your current location (based on your IP address). You can opt out of allowing us to collect this information either by refusing access to the information or by disabling your Location setting on your device. However, if you choose to opt out, you may not be able to use certain aspects of the Services.
In Short: We process your information to provide, improve, and administer our Services, communicate with you, for security and fraud prevention, and to comply with law. We may also process your information for other purposes with your consent.
We process your personal information for a variety of reasons, depending on how you interact with our Services, including:
To fulfill and manage your orders
We may process your information to fulfill and manage your orders, payments, returns, and exchanges made through the Services.
To enable user-to-user communications
We may process your information if you choose to use any of our offerings that allow for communication with another user.
To send marketing and promotional communications
We may process the personal information you send to us for our marketing purposes, if this is in accordance with your marketing preferences.
To deliver targeted advertising
We may process your information to develop and display personalized content and advertising tailored to your interests, location, and more.
To protect our Services
We may process your information as part of our efforts to keep our Services safe and secure, including fraud monitoring and prevention.
In Short: We only process your personal information when we believe it is necessary and we have a valid legal reason (i.e., legal basis) to do so under applicable law, like with your consent, to comply with laws, to provide you with services to enter into or fulfill our contractual obligations, to protect your rights, or to fulfill our legitimate business interests.
The General Data Protection Regulation (GDPR) and UK GDPR require us to explain the valid legal bases we rely on in order to process your personal information. As such, we may rely on the following legal bases to process your personal information:
• Consent
We may process your information if you have given us permission (i.e., consent) to use your personal information for a specific purpose. You can withdraw your consent at any time.
• Performance of a Contract
We may process your personal information when we believe it is necessary to fulfill our contractual obligations to you, including providing our Services or at your request prior to entering into a contract with you.
• Legitimate Interests
We may process your information when we believe it is reasonably necessary to achieve our legitimate business interests and those interests do not outweigh your interests and fundamental rights and freedoms. For example, we may process your personal information for some of the purposes described in order to:
• Legal Obligations
We may process your information where we believe it is necessary for compliance with our legal obligations, such as to cooperate with a law enforcement body or regulatory agency, exercise or defend our legal rights, or disclose your information as evidence in litigation in which we are involved.
• Vital Interests
We may process your information where we believe it is necessary to protect your vital interests or the vital interests of a third party, such as situations involving potential threats to the safety of any person.
In legal terms, we are generally the "data controller" under European data protection laws of the personal information described in this privacy notice, since we determine the means and/or purposes of the data processing we perform. This privacy notice does not apply to the personal information we process as a "data processor" on behalf of our customers. In those situations, the customer that we provide services to and with whom we have entered into a data processing agreement is the "data controller" responsible for your personal information, and we merely process your information on their behalf in accordance with your instructions. If you want to know more about our customer's privacy practices, you should read their privacy policies and direct any questions you have to them.
We may process your information if you have given us specific permission (i.e., express consent) to use your personal information for a specific purpose, or in situations where your permission can be inferred (i.e., implied consent). You can withdraw your consent at any time.
In some exceptional cases, we may be legally permitted under applicable law to process your information without your consent, including, for example:
If collection is clearly in the interests of an individual and consent cannot be obtained in a timely way
For investigations and fraud detection and prevention
For business transactions provided certain conditions are met
If it is contained in a witness statement and the collection is necessary to assess, process, or settle an insurance claim
To save or protect an individual's vital interest. We may process your information when necessary to save or protect an individual's vital interest, such as to prevent harm.
In Short: We may share information in specific situations described in this section and/or with the following categories of third parties.
Vendors, Consultants, and Other Third-Party Service Providers. We may share your data with third-party vendors, service providers, contractors, or agents ("third parties") who perform services for us or on our behalf and require access to such information to do that work. We have contracts in place with our third parties, which are designed to help safeguard your personal information. This means that they cannot do anything with your personal information unless we have instructed them to do it. They will also not share your personal information with any organization apart from us. They also commit to protect the data they hold on our behalf and to retain it for the period we instruct. The categories of third parties we may share personal information with are as follows:
Ad Networks
Affiliate Marketing Programs
Cloud Computing Services
Communication & Collaboration Tools
Data Analytics Services
Data Storage Service Providers
Finance & Accounting Tools
Government Entities
Order Fulfillment Service Providers
Payment Processors
Performance Monitoring Tools

We also may need to share your personal information in the following situations:
• Business Transfers
We may share or transfer your information in connection with, or during negotiations of, any merger, sale of company assets, financing, or acquisition of all or a portion of our business to another company.
• Business Partners

In Short: We keep your information for as long as necessary to fulfill the purposes outlined in this privacy notice unless otherwise required by law.
We will only keep your personal information for as long as it is necessary for the purposes set out in this privacy notice, unless a longer retention period is required or permitted by law (such as tax, accounting, or other legal requirements). No purpose in this notice will require us keeping your personal information for longer than the period of time in which users have an account with us.
When we have no ongoing legitimate business need to process your personal information, we will either delete or anonymize such information, or, if this is not possible (for example, because your personal information has been stored in backup archives), then we will securely store your personal information and isolate it from any further processing until deletion is possible.
In Short: We aim to protect your personal information through a system of organizational and technical security measures.
We have implemented appropriate and reasonable technical and organizational security measures designed to protect the security of any personal information we process. However, despite our safeguards and efforts to secure your information, no electronic transmission over the Internet or information storage technology can be guaranteed to be 100% secure, so we cannot promise or guarantee that hackers, cybercriminals, or other unauthorized third parties will not be able to defeat our security and improperly collect, access, steal, or modify your information. Although we will do our best to protect your personal information, transmission of personal information to and from our Services is at your own risk. You should only access the Services within a secure environment.
In Short: In some regions (like the EEA, UK, and Canada), you have rights that allow you greater access to and control over your personal information. You may review, change, or terminate your account at any time.

You can withdraw your consent at any time by contacting us by using the contact details provided in the section "HOW CAN YOU CONTACT US ABOUT THIS NOTICE?" below.
However, please note that this will not affect the lawfulness of the processing before its withdrawal, nor when applicable law allows, will it affect the processing of your personal information conducted in reliance on lawful processing grounds other than consent.
You can unsubscribe from our marketing and promotional communications at any time by clicking on the unsubscribe link in the emails that we send, or by contacting us using the details provided in the section "HOW CAN YOU CONTACT US ABOUT THIS NOTICE?" below. You will then be removed from the marketing lists. However, we may still communicate with you — for example, to send you service-related messages that are necessary for the administration and use of your account, to respond to service requests, or for other non-marketing purposes.
If you would at any time like to review or change the information in your account or terminate your account, you can contact us using the contact information provided.
Upon your request to terminate your account, we will deactivate or delete your account and information from our active databases.

Most web browsers and some mobile operating systems and mobile applications include a Do-Not-Track ("DNT") feature or setting you can activate to signal your privacy preference not to have data about your online browsing activities monitored and collected. At this stage no uniform technology standard for recognizing and implementing DNT signals has been finalized. As such, we do not currently respond to DNT browser signals or any other mechanism that automatically communicates your choice not to be tracked online. If a standard for online tracking is adopted that we must follow in the future, we will inform you about that practice in a revised version of this privacy notice.
