Who we are

Quack Marketing Ltd is operated by EyeLinkMedia Holding Limited is a company registered in England at 5th Floor, 1 Dover Place, Ashford Commercial Quarter, Ashford, Kent TN23 1FB with company number 11481021.

Quack has designated a Data Protection Officer and they can be reached by emailing or by post at the address above.

Who can use Quack?

If you are in the UK or the US, you must be aged 13 or over to sign up for a Quack profile. If you are not in the UK or US, depending on where you live, you may need to be older. You can only use Quack if you are allowed to do so by law.

When you sign up to use Quack, you'll be asked to confirm your date of birth so that we can check that you are 13 or over (don't lie about your age – that's an important rule).

How is my personal information used by Quack to provide the Quack services to me?

Quack is a messaging app that allows users to message and send photos to their contacts who have also downloaded the Quack app. When you sign up to Quack, the app will access the contacts on your device so that you can see your contacts who are also using Quack. You will also be able to see the Quack profiles of friends of friends who are on Quack (this is referred to as the “Circle”) and they will be able to see that you are on Quack.

Friends of friends who are in your Circle can’t see your full name or phone number, but they will be able to see your profile, your profile photo and the number of, and names of, friends you have in common. They can also see the name that you have saved to your profile on the app during registration (which doesn’t need to be your real name), and any information that you have voluntarily added to the “About” and “Work and Education” sections or your profile.

Quack users can send a request to start chatting to people in the Circle. If you accept a chat request, then you become a contact within Quack and you can send messages within Quack, however the other Quack user still cannot see your phone number. They will only see the limited profile information as set out above.

You have the option to allow Quack to show your location at city level in your profile (for example if you are within London your location would be shown as “London”). If you allow your location to be shown, the Quack app will collect information about your location from your phone (latitude and longitude). If you permit your location to be shown it will only be visible to other users who are sharing their location.

If location data is enabled, users can search within contacts and members of their Circle by city location. All users can also search within contacts and members of their Circle by applying age and/or gender filters.

If you have enabled location services, but wish to turn it off, you can do so by the following methods:

  1. iPhone app — settings, privacy, location services, Quack
  2. Android — settings, security and location, location, Quack

You also have the option to allow Quack to show you other Quack users who are near you. If you allow this function the Quack app will collect information about your location from your phone via Bluetooth. You will also appear as nearby to Quack users who are sharing their Bluetooth data. You can turn off this functionality under Privacy and security, Bluetooth discovery. If you have disabled Bluetooth on your phone settings, then this function will not be available.

You control your user profile. These details are available to you at any time by accessing your profile in Quack. You can correct and update the information in your profile at any time but you are only able to change your date of birth and your gender once within the profile. If you have any issues, you can contact Quack’s Customer Support Team at

Please be careful about posting private and sensitive details about yourself on your profile. Remember that this can be seen by other Quack users. Some information has special protection under data protection laws and is called “special category data”. This includes information about your religious beliefs, your ethnic origin, your political opinions, your health, your sexual orientation and sex life. You may decide to voluntarily provide this type of information in your profile. Please remember that any photographs that you post on Quack may reveal these kinds of special category data. Where you do include this type of information in your profile, you are explicitly consenting to Quack processing your information and making this public to other users. You can change your profile at any time to remove this information.

For safety and security and to ensure you have the best possible user experience, we require users to verify the mobile phone number that they use to register for a Quack account. To do this we send a code to the mobile phone number that is provided and that code must be entered into Quack to enable an account to be created. We want to make sure you are not a robot! And we also want to avoid fake Quack accounts being created which can be used for malicious activities and cyber crime – they threaten the Quack network and spoil things for everyone. We use a third party provider for account verification who will keep your phone number for up to 90 days for fraud identification purposes.

To prevent abuse of the app/site, Quack uses automated decisions to block accounts as part of its anti-spam procedures. In order to do this, our systems check accounts and messages for content that indicates breaches of our Terms & Conditions. If an account or message meets certain criteria that demonstrate that the Terms & Conditions are likely to have been breached, the relevant account will automatically be blocked. All users of accounts that have been blocked will be notified that their account has been blocked and affected users can contact Quack to contest the decision.

Quack also uses automated decisions to prevent fraudulent payment transactions being processed as part of its anti-fraud procedures. In order to do this, our systems check payment transactions for behaviour that indicates breaches of our Terms & Conditions. If a transaction meets certain criteria that demonstrate that the Terms & Conditions are likely to have been breached and the transaction is likely to be fraudulent, the relevant transaction may automatically be blocked. Where a transaction is blocked, the user will be notified that their transaction cannot be processed and affected users can contact Quack to contest the decision.

Please note that if your account is blocked, any account(s) that you have on our other group platforms/applications may also be blocked as part of our anti-spam and anti-fraud procedures.

How long will Quack keep my data?

We keep your personal information only as long as we need it for legitimate business purposes (as set out above) and as permitted by applicable law.

In practice, we delete or anonymise your information upon deletion of your account (following the safety retention window), unless:

  1. we must keep it to comply with applicable law (for instance, some “traffic data” is kept for one year to comply with statutory data retention obligations);
  2. we must keep it to evidence our compliance with applicable law (for instance, records of consents to our Terms & Conditions, Privacy Policy and other similar consents are kept for five years);
  3. there is an outstanding issue, claim or dispute requiring us to keep the relevant information until it is resolved; or
  4. the information must be kept for our legitimate business interests, such as fraud prevention and enhancing users' safety and security. For example, information may need to be kept to prevent a user who was banned for unsafe behaviour or security incidents from opening a new account.

Where Quack uses machine learning, for example, to help us detect and prevent fraudulent card transactions, and to detect and prevent spam communications on the app (as explained above), we may need to keep personal information for a longer period than the retention periods explained above, to enable the machine learning to work properly. Where this is the case, we always seek to minimize the amount of personal information that is used and we ensure that it is ring-fenced and kept securely from other user personal information. We regularly review the period for which personal information is required for machine learning purposes and delete any identifiable information when it is no longer required.

What information does Quack collect about me if I’m under 13?

Quack does not knowingly collect any information about or market to anyone under the age of 13. If we become aware that somebody who is under 13 years old has registered with us and provided us with personal data, we will take steps to terminate that person’s registration and delete their profile information from Quack. If we do delete a profile because you violated our age restriction rules, we may retain your mobile number and IP address to ensure that you do not try to get around our rules by creating a new profile.

Who does Quack share information with?

We may share aggregated information that includes your personal data (but which doesn’t identify you directly), together with other information including log data with third parties for industry analysis and demographic profiling.

We share your data with the following categories of third-parties:

  1. Information technology companies (hardware and software) which provide services to support our products
  2. Fraud prevention and anti-spam providers to protect the service from criminal activity
  3. Moderators to monitor activity on the site/apps and approve content
  4. Law enforcement agencies, where we are required to by law or to protect the vital interests of a person

We ensure these parties must adhere to strict data protection and confidentiality provisions that are consistent with this Policy. Measures are taken to ensure that the data shared is non-attributable to the greatest extent possible.

In the event that Quack or any of its affiliates undergoes a business transition or change of ownership, such as a merger, acquisition by another company, re- organisation, or sale of all or a portion of its assets, or in the event of insolvency or administration, we may be required to disclose your personal data.

Your data may be shared with other Quack group companies, for example, to block accounts and suspected fraudulent payment transactions as part of our anti-spam and anti-fraud procedures.
