3.5 Data Sharing between Reactive Mart Affiliates

As set out above under "Personal data from other sources", we also receive access to personal data about you from Reactive Mart Affiliates. This enables us, in particular, to provide you, with your consent as legally required, with information about products and services, which we believe might interest you, and improve our products, services, content, and advertising by analysing your use of the services of Reactive Mart Affiliates, in particular through the matching of certain data (e.g. cookie IDs). Furthermore, this allows us to better prevent, detect, mitigate and investigate fraud, security incidents and other prohibited or unlawful activities, including the assessment of corresponding risks. We will also grant access to personal data about you to Reactive Mart Affiliates for the aforementioned purposes. To the extent that Reactive Mart Affiliates have access to your personal data, they will follow practices that are at least as restrictive as the practices described in this User Privacy Notice.

3.6 Automated decision-making

We use technologies that are considered automated decision making or profiling. We will not make any automated decisions about you that would significantly affect you unless such a decision is necessary for entering into, or the performance of, a contract with you, we have obtained your consent, or we are required by applicable law to use such technology.

4. Storage duration and erasure

Your personal data will be stored by us and our service providers in accordance with applicable data protection laws to the extent necessary for the processing purposes set out in this User Privacy Notice. Subsequently, we will delete your personal data in accordance with our data retention and deletion policy or take steps to properly render the data anonymous, unless we are legally obliged or permitted to keep your personal data longer (e.g. for legal compliance, tax, accounting or auditing purposes, or to detect and prevent fraudulent or illegal activity on Reactive Mart). In Europe, the retention periods are generally between 6 and 10 years (e.g. for contracts, notifications and business letters). As far as legally permissible or required, we restrict the processing of your data instead of deleting it (e.g. by restricting access to it). This applies in particular to cases where we may still need the data for the execution of the contract or for the assertion of or defence against legal claims, or where such retention is otherwise required or permitted by law. In these cases, the duration of the restriction of processing depends on the respective statutory limitation or retention periods. The data will be deleted after the relevant limitation or retention periods have expired.


Learn more about section 4

The specific retention periods for personal data are documented in our regional data retention guidelines. How long we retain personal data may vary depending on the Services we provide and our legal obligations under applicable national law. The following factors typically affect the retention period:

  • Necessity for the provision of our Services
    This includes such things as executing the User Agreement with you, maintaining and improving the performance of our products, keeping our systems secure, and maintaining appropriate business and financial records. Most of our retention periods are determined on the basis of this general rule.
  • Consent-based processing of personal data
    If we process personal data on the basis of consent (including consent to the extended storage), we store the data for as long as necessary in order to process it according to your consent.
  • Statutory, contractual or other similar obligations
    Corresponding storage obligations may arise, for example, from laws or official orders. It may also be necessary to store personal data with regard to pending or future legal disputes. Personal data contained in contracts, notifications and business letters may be subject to statutory storage obligations depending on national law.

5. Rights as a data subject

Subject to possible restrictions under national law, as a data subject, you have the right to access, rectification, erasure, restriction of processing and data portability with regard to your personal data. In addition, you can withdraw your consent and object to our processing of your personal data on the basis of our legitimate interests. You can also lodge a complaint with a supervisory authority.

Exercising your rights and managing your settings

You are free to contact the Reactive Mart Team or the controller who is responsible for the processing of your personal data at any time. The exercise of data subjects' rights (e.g. right to access or erasure) is generally free of charge. Where requests are manifestly unfounded or excessive, in particular because of their repetitive character, we may charge an appropriate fee (at most our actual costs), in accordance with the applicable statutory regulations, or refuse to process the application.


Managing your communication preferences

If you would like to change your preferences regarding Reactive Mart communications (including marketing communications), you can do so at any time through your account in Reactive Mart under "Communication Preferences". If you no longer wish to receive email marketing communications from us, you can also unsubscribe by clicking on the link in the footer of the email you received. For technical reasons, the implementation may take a few days.

7. Data Security

We protect your personal data through technical and organisational security measures to minimise risks associated with data loss, misuse, unauthorised access and unauthorised disclosure and alteration. To this end we use network security services and data encryption, for example, as well as physical access restrictions for our data centres and logical access controls for data and systems access.

8. Other important information regarding data protection

This section contains important additional information about the protection of personal data in connection with the use of our Services, including whether you are required to provide personal data.

Learn more about section 8

What happens when you share your personal data on our sites or applications?

Other users have access to the information you share on Reactive Mart or disclose to other users. For example, other users can see your bids, purchases, items for sale, saved interests, sellers and searches, shopfronts, Feedback, ratings, product reviews and associated comments. Other users can also see any information you choose to share in your profile.

When you use our Services, your public user ID may be displayed and available to the public and associated with all of your public Reactive Mart activity. Notices sent to other users about suspicious activity and notice violations on our sites may refer to your public user ID and specific items. Accordingly, if you use a username that allows others to identify you, these others may be able to identify your Reactive Mart activities.

To help protect your personal data, we allow only limited access to other users' contact, delivery and financial information as necessary to facilitate your transactions and collect payments. However, when users are involved in a transaction, they have access to each other's name, user ID, (alias) email address and other contact and delivery information. For example, we may allow users to exchange telephone numbers in order to contact each other prior to completing a transaction (e.g. a seller may opt to share their telephone number with a buyer so that the buyer may call with questions about a listed item). In this case, sellers are prohibited from using a buyer's telephone number for other purposes (e.g. completing a transaction off Reactive Mart or adding the buyer to a marketing list).

Your responsibilities over transactional information you receive through Reactive Mart

When you complete a transaction with another user (or a transaction has been cancelled, failed, or subsequently invalidated), we will provide you with the other user's personal data (such as name, username, (alias) email address, contact information, delivery and billing information, or return address). Independent from us, you are the controller of such data and responsible for any processing that you perform after we have shared this data with you, including compliance with any limitations imposed by this User Privacy Notice and our User Agreement.

Unless you act for purely personal purposes, we recommend that you explain your data processing activities in your own privacy notice and protect the privacy of other users. As a seller, you must in any case comply with the applicable data protection laws and in particular protect the rights of other users as data subjects, e.g. give them the opportunity to access the personal data collected by you and demand that it be erased.

You may only use the personal data that you have access to for Reactive Mart transaction-related purposes, or for other Services offered through Reactive Mart (such as delivery, fraud complaints, and member-to-member communications), and for purposes expressly consented by the user to whom the data relates. Using personal data of other users that you have access to for any other purpose, such as adding them to a mailing list without their express consent, constitutes a violation of our Terms & Conditions.

Personal data relating to third parties

If you provide us with personal data relating to another person, you must obtain the consent of this person or the disclosure of the data to us must be otherwise legally permissible. You must inform the other person of how we process personal data in accordance with our User Privacy Notice.

Filtering of messages sent via our messaging tools

All messages sent via our messaging tools are first received by us and then forwarded to the recipient. All messages are automatically filtered according to certain criteria. If necessary, conspicuous messages are checked manually by our customer service. In the event of a violation of our Terms & Conditions, we reserve the right to block the transmission of the message and to restrict the purchase and sales functions of your Reactive Mart account or to block your Reactive Mart account.

Are you obliged to provide your personal data to us?

Some of the personal data that you provide to us (e.g. data by which we can identify you) are required to enter into the Terms & Conditions. As described in our Terms & Conditions, we may share this data with other Reactive Mart Affiliates in order to facilitate transactions and with service providers, including payment processors, credit agencies and bureaus. Although the provision of any other personal data (e.g. address and delivery data) is voluntary, it may be necessary for the use of our Services, such as bidding, purchase and sales data to complete a transaction.

Children's Privacy

Our services are not intended for the use by children. We do not knowingly collect personal data from users who are considered children under applicable national laws. Under our User Agreement, children are not permitted to use our Services.

Staying signed in

When you sign into your account on our Services, we give you the option to stay signed into your account for a certain amount of time. If you are using a public or shared computer, we encourage you to decline. You or any other user of the computer/browser you signed in on will be able to view and access most parts of your account and take certain specific actions during this signed in period without any further authorisation. The specific actions and account activities that you or any other user of this computer/browser may take include:

  • Bid, buy or make an offer on an item
  • Check out or add items to your cart
  • Purchase an item with PayPal using Faster Checkout (if enabled in your account)
  • View the activity header
  • View the My Reactive Mart page
  • View or edit the Watch List or order details
  • View the profile page
  • Send member-to-member messages
  • Conduct after-sale activities, like leaving Feedback, cancelling orders, requesting returns or submitting claims

If you attempt to change your password or user ID, update any other account information or attempt other account activity beyond those listed above, you may be required to enter your password.

You can typically end your signed in session by either signing out and/or clearing your cookies. If you have certain browser privacy settings enabled, simply closing your browser may also end your signed in session. If you are using a public or shared computer, you should sign out and/or clear your cookies when you are done using our Services to protect your account and your personal data.
