Circle Lab’s Privacy & Cookies Policy (“Privacy Policy”) was last updated on 28 August, 2018.

Circle Economy does not sell or rent your Personal Information (later defined) to third parties without your explicit consent. Please read this Privacy Policy to learn more about the ways in which Circle Economy uses and protects your Personal Information.

This Privacy Policy applies to the Circle Economy content on the internet site located at along with any related websites, networks, and other services provided by Circle Economy (collectively the “Platform” or “Circle Lab”). By using the Platform you agree to be bound by the terms and conditions of this Privacy Policy. Capitalized terms not defined in the Privacy Policy have the meanings ascribed to them in the Terms and Conditions of Use (the "TOU"). If you do not agree to the Privacy Policy or the TOU please do not use or access the Platform.

This Privacy Policy describes the information we collect from you and what may happen to that information. By accepting the Privacy Policy, you expressly consent to Circle Lab’s use and disclosure of your Personal Information in accordance with this Privacy Policy.

This Privacy Policy may be updated from time to time, so we advise visitors to consult it regularly for changes. We will notify you of any material changes by prominently posting notice of the new Privacy Policy to the Platform and/or by sending you an email to the last email address provided to us. You are advised to consult this Privacy Policy regularly for any changes.

As used in this Privacy Policy, the terms "using" and "processing" information include using cookies on a computer, subjecting the information to statistical or other analysis and using or handling information in any way, including, but not limited to collecting, storing, evaluating, modifying, deleting, using, combining, disclosing and transferring information within our organization or among our affiliates within the Netherlands or internationally.

Our primary purpose in collecting your first name, email address, age, interests, username, and password when you register to the Platform (the “Login Information”) is to:  (i) provide you with a safe, smooth, and efficient experience and to adjust our products and services, (ii) be able to contact you in connection with any Contribution that you submit, (iii) administer your account, and (iv) communicate with our Users or schedule any technical work to the Platform with minimal interference. Any information about you that can be used to contact or identify you is personal information ("Personal Information"). We only collect the minimum amount of Personal Information about you that we consider necessary for achieving the aforementioned purposes. Your email address is not displayed publicly on the Platform but it will be displayed to Moderators (as defined in the TOU).
Your Login Information is held within your account called My Profile. This is (i) created when you register on the Platform and (ii) added to at will by you the user. It is each user’s decision as to whether they add additional Personal Information to their My Profile section or upload a photograph/image of themselves and opt to make these visible to Other Users as part of My Profile.

In general, you can browse the Platform without telling us who you are or revealing any Personal Information about yourself. Once you register, create My Profile, or submit a Contribution you are not anonymous to us. As only Users can submit a Contribution on the Platform, if you choose to submit a Contribution prior to registering to the Platform, we will require you to first (i) register with your Login Information thus creating My Profile and if applicable (ii)  agree to any Challenge Rules. All Contributions will be viewable by Other Users of the Platform. You always have the option to not provide information by choosing not to register or submit a Contribution.

If you register and create My Profile, choose to submit Contributions, or post messages on the Platform, we will collect and store that information you provide to us. If you delete your account on the Platform, your user data will be removed from the Platform and your My Profile will be deleted, however your posts and comments may still be visible under the alias “Deleted User.”

If you send us personal correspondence, such as emails or letters, or if Other Users or third parties send us correspondence about your activities or postings on the Platform, we may collect such information into a file specific to you.

We use your Login Information in the file we maintain about you, and other information we obtain from your current and past activities on the Platform to:

Contact you about any Contributions
Contact you with Notifications
Send you suitable Challenges and newsletters
Contact you with feedback surveys
Troubleshoot problems and resolve disputes
Detect and protect us against error, fraud and other criminal activity
Enforce the TOU

We may use your Login Information to analyse customer behaviour and to adjust our products and services accordingly, to ensure that it is relevant; to contact you with information about new features and updates about the Platform and Circle Lab including offering new functionalities, changing the User experience, and updating functionalities; and other information that you may be interested in based on your account details, websites you have visited and the data you have entered into our websites, your online and offline history and your registered use of Circle Economy or other Circle Economy websites.

Further, we regularly conduct research on the level of satisfaction of Users, through the use of feedback surveys. We use your responses to such surveys for quality assessments and to improve your customer experience.

Based on the information above, we can make adjustments to the Platform. We may also adapt our promotions on the basis of our analysis. We may also perform research into market trends through statistical analysis to evaluate and adapt our products and marketing to new developments, but research results are only reported on an aggregated basis.

We may share aggregated information that does not include Login Information and we may otherwise disclose information that does not identify you (“Non-Identifying Information”) and information about your activities on the Platform (“Log Data”) with third-parties for industry analysis, demographic profiling, academic research, and other purposes. Any aggregated information shared in these contexts will not contain your Personal Information.

You agree that we may use your Login Information to contact you. By accepting the TOU, you expressly agree that we may contact you as provided herein.

Circle Economy may disclose information it has collected from you and/or Contributions you have made available on the Platform when it believes in good faith that the law or legal process requires it, or when it is necessary to do so to protect the rights or property of Circle Lab, Challenge Issuers, or others. As a matter of policy, we do not sell or rent any of your Personal Information to third parties without your explicit consent. The following describes some of the ways that your Personal Information may be disclosed in the normal scope of our business and you authorize us to do this for the purposes of the use and operation of the Platform, or any investigations of the information on the Platform.

Challenge Issuer: A Challenge Issuer cannot store or disclose your Personal Information; this can only be done by Circle Economy in compliance with this Privacy Policy. Circle Economy may share information that you have entered in My Profile with a Challenge Issuer to analyze Users’ Contributions for the Challenge Issuer’s own Challenges.

Other Users: When you post Contributions to the Platform, including ideas and comments, certain Personal Information about you, such as your user name, identifying photo, and Profile Content may – and likely will be – displayed on the Platform. More sensitive Personal Information, such as your postal address, e-mail address, phone number, will NOT be displayed on the Platform. Other Users, including Users who come to Circle Lab via a link posted on a third party website, including Third Party Sites, will have access to the publicly displayed information. We are not responsible for privacy practices of the Other Users who will view and use the posted information you choose to make available on or through Circle Lab. You should therefore be mindful of these types of disclosures when selecting a User name or choosing the photograph to use with your account.

Service Providers for Our Operations: We may use third parties, such as Mailchimp and Mandrill, that we refer to as service providers to facilitate or outsource one or more aspects of our business, including as part of our registration process or to facilitate our mailing lists. Therefore we may provide some of your Personal Information directly to these service providers, or this information may come available to them in the course of our business with them. We recommend you review the privacy policies of these service providers.

Other Entities: We may share our data, including Personal Information about you, with our affiliates and subsidiaries. To the extent these entities have access to your information, they will treat it at least as protectively as they treat information they obtain from their users. To the extent allowed by applicable law, these entities follow privacy practices that are no less protective of users than the practices described in this Privacy Policy. Circle Economy may share some or all of your Personal Information, Non-Identifying Data and Log Data with another business entity should we plan to reorganize, spin out, merge with, acquire, or be acquired by that business entity. Should such an event occur, we will require that the new or combined entity follow this Privacy Policy with respect to your Personal Information. If your Personal Information will be used contrary to this Privacy Policy, you will receive prior notice as previously described.

Legal Requests: Circle Economy cooperates with law enforcement inquiries, as well as other third parties to enforce laws and intellectual property rights. Therefore, in response to a verified request by law enforcement or other government officials relating to a criminal investigation or alleged illegal activity, we can disclose Login Information including name and email address, and without limiting the above, in an effort to respect your privacy, we will not otherwise disclose your Personal Information to law enforcement or other government officials without a subpoena, court order or substantially similar legal procedure, except when we believe in good faith that the disclosure of information is necessary to prevent imminent physical harm or financial loss; or to report suspected illegal activity.

Due to the existing regulatory environment, we cannot ensure that all of your private communications and other Personal Information will never be disclosed in ways not otherwise described in this Privacy Policy. By way of example and without limiting the foregoing, we may be forced to disclose your Personal Information to the government or third parties under certain circumstances or third parties may unlawfully intercept or access transmissions or private communications. Therefore, although we use industry standard practices to protect your privacy, we do not promise, and you should not expect, that your Personal Information or private communications will always remain private.

You agree to maintain and promptly update and keep accurate, current and complete any information provided to Circle Lab as part of My Profile. You can change your username, email address, password, contact and other information by going to My Profile. Your previous Contributions will be associated with the updated information. You may update or correct your profile information and preferences at any time on the Platform or by emailing us at

Your personal profile will be made available to Other Users. Be aware that Other Users can object to any content on My Profile if they believe it is damaging or offensive. Your recent Contributions and current and past Challenges, are shown on your My Profile page. 

If you would like us to delete your account record in our system, you are able to do so by contacting us at with a request to delete your account, providing your username, and entering “Delete my account” in the subject line. We will use commercially reasonable efforts to honor your request. Removal of this content or information from public view does not guarantee complete or comprehensive removal. After your removal request has been honored, we may retain an archived copy of your records as required by law or for legitimate business purposes. We are not required to remove your posted content or information if it has been rendered anonymous or if we are required by law to retain it. Additionally, we do not have control over third parties (e.g., Other Users) who may have copied or reposted this information. If you have included Login Information in online forum postings or in information or communications shared with Other Users, you may not be able to update, correct or delete this information from the Platform.

Upon creating your account, we will send you your Login Information. These personal data enable us to administer your account and enables us to ensure the confidentiality and to maintain the security of your information. We are, for instance, able to change your password for you. We are, however, not able to view your password.

You are responsible for all actions taken with your Login Information. Accordingly, you agree to maintain and safeguard the confidentiality of your Login Information, and to not share your Login Information with any third party. We recommend that you do not disclose your password to any third parties. If you choose to share your username and password or your Personal Information with third parties, you are responsible for all actions taken with your account and therefore you should review that third party’s privacy policy. If you lose control of your password, you may lose substantial control over your Personal Information and may be subject to legally binding actions taken on your behalf. Therefore, if your password has been compromised for any reason, you should immediately change your password. If you need help changing your password, please contact

To the extent that you disclose your information to other parties on our Platform or other sites throughout the internet, different rules may apply to their use or the disclosure of information you disclose to them.
