1. Visit of our Website

Via the Website you can find information about us, contact us, indicate that you have lost an Item, indicate that you have found an Item, send an 5Lost Alert or register your belongings. You can also register here for our newsletters.

When you visit our Website, we process, among other things, your IP address and browser identification (user-agent). We also process data about your visit to the Website. We use cookies on our Website. You can find more information about the Personal Data that we process about you when you visit the Website in our Cookie Statement. If you have registered for our newsletters we can keep track of how many people have opened the newsletter and which information has been clicked. In our newsletter we provide (promotional) information about our products and services.

2. Account creation

When you create an account on the Website, we process Personal Information such as your name and email address. In addition, 5Lost Alerts, Claims, registration of Items and registration of possessions on the Website are linked to this account.

3. Found item registration

When you register an Item as a private Finder, we process your contact information and data about the Item to support registration. This includes your name, telephone number, email address, a description of the Item, a photo of the Item, location, find date and other information that you provide in the open text fields. The data of the private Finder is shared with the potential owner if necessary (or vice versa: the data of the potential owner with the private Finder). This only happens if 5Lost believes that this is necessary to ensure that the Item is returned to the owner. The data that is processed are name and email address. Usually communication between Finder and owner takes place via the 5Lost Platform.

4. Claim found item

If you lost something and the Item is registered on the 5Lost Platform, you can indicate that the Item is yours. You then make a so-called Claim. You must then prove that you are the rightful owner. You create an account so that ownership can be verified and we can contact you regarding updates on this claim.

We process the following information about you: account information and information that you provide in the context of the Claim.

We also process information about your lost Item, including the description of the Item completed by the Finder, a photo of the Item, information about the location and other information that the Finder has provided. This can be, for example, your date of birth, place of birth, last name, first name, address, card number, card and document by name, IMEI number and / or telephone number. The Finder receives a notification of the Claim and verifies whether the Item is actually yours. If there is a Match, there are a number of options for getting the Item back. If you choose to send, we will process your last name, first name, (delivery) address, email address and telephone number as well as financial data, including your bank details.

5. Owner notification

Sometimes an Item is registered on the 5Lost Platform, but the Finder already has a strong suspicion of who the owner is. For example, if a wallet is found with a name and telephone number. In those cases, 5Lost can send a notification on behalf of the Finder. A notification may include the following information: name, email address, telephone number and information about the Item, such as find date and place.

6. 5Lost Alert

If you have lost an Item and the Item has not been registered on the 5Lost Platform after three working days, we recommend sending an 5Lost Alert. The 5Lost Alert is addressed to organizations that do not yet use 5Lost. You can also share the 5Lost Alert on social media. If you create an 5Lost Alert, we can process the following Personal Data: account details, insurer and information about the Item, such as the date and place of loss and a description of the Item.

7. Creating an insurance claim form (for insurers)

It is possible to create a claim form for your insurance with details of the Item for which you are the rightful owner. We can then process your surname, first name, address, date of birth, a description of the Item and a photo of the Item.

8. Saved search

When you create a saved search, we process your email address that you share with us in relation with your saved search. That way we can notify you about new reported items that match your search. After the period that you will be kept informed of new found items has expired, your information will be automatically deleted.

9. Customer Support

When you contact us, we process your name, email address and / or telephone number and other information that you share with us in connection with your question or request. That way we can handle your questions, requests or complaints and maintain contact.

Basis for processing

We can only process Personal Data if there is a legal basis for this.

Execution of the agreement

We can process Personal Data because we have an agreement with you. This can be a service agreement or other agreements that we have agreed with you.

Legitimate interest

We may process Personal Data because we have a legitimate interest in this. This may be necessary to secure our systems or to monitor and improve the quality of our services. We also have a legitimate interest in bringing our products and services to the attention of our (existing) customers. When we process Personal Data because we have a legitimate interest in doing so, we will first carefully weigh your interests against our own.

Legal obligation

We may process your Personal Data because it is necessary in connection with a legal obligation imposed on us. This is the case when we process Personal Data to comply with privacy obligations, such as (at your request) providing information. For example, we must also process Personal Data for the Tax Authorities.


If none of the aforementioned principles apply, we will ask for permission before we process your Personal Data. When we ask you for permission, we clearly inform what we are asking for. You can withdraw your consent at any time.

Retention of Personal data

We do not keep your Personal Data longer than necessary for the purposes for which it is processed. Our retention period depends on the purpose for which we process your Personal Data and whether we have other legal retention obligations. In principle, we retain your Personal Data for a period of five years after you were last active, your account was terminated or after the agreement with 5Lost was terminated. We opt for a term of five years so that we can properly handle potential liability claims. In addition, we generally keep financial documents for the Tax Authorities for seven years. After this period we will destroy your data or anonymize it in such a way that no Personal Data remains. We will not use the aforementioned retention periods if you have requested us to delete your Personal Data. You can read more about your rights later in this Privacy Policy under “Your Rights”.

People with access to your personal data

We may provide employees and other persons acting under the authority of 5Lost access to your Personal Data. We only make our database available if it is necessary and cannot be otherwise. In addition, employees and other persons acting under the authority of 5Lost have a duty of confidentiality, unless they are required by law to make statements. We may engage third parties in the implementation and / or delivery of our products and services. To the extent that these third parties thereby process your Personal Data on our behalf, they do so as a Data Processor and in that case we have entered into a data processing agreement. Among other things, it states that processors must take appropriate technical and organizational measures to protect your Personal Data. We may also share your Personal Data with third parties that act as a Data Controller. These may include Finders who have reported the Item. We also use external payment providers and shipping companies. These and other third parties are often themselves responsible for the way in which they process your Personal Data and have their own obligation to inform you about this. We only provide your Personal Data to supervisors, tax authorities and investigative bodies if this is required by law.

Personal data outside the European Economic Area (“EEA”)

5Lost is based in the EEA. Your Personal Data will in principle only be processed within the EEA. We may use service providers or hosting parties that are located outside the EEA. In these cases we will take measures to ensure that this transfer complies with the GDPR, for example by concluding a transfer agreement based on the Standard Contractual Clauses.


When processing Personal Data, we ensure a level of security that, given the state of the art, should be sufficient to prevent unauthorized access to and modification, disclosure or loss of Personal Data. We have at least taken the following security measures:

  • Logical access control through role-based access;
  • Physical measures for access security;
  • Organizational measures for access security;
  • Random checks on compliance with our policy;
  • Encryption of all communication top and from the 5Lost Platform;
  • Security of our internal network.
