Data that we collect automatically

We automatically collect data and keep records of how and when you use our HuYu app and data about your phone. Some of this is essential (because HuYu wouldn’t work without it) and some of this is to help us improve HuYu. Automatically collected data includes:

  • App use data:
    • Your IP address (this is the place from which you connect to the internet and comes to us which is displayed as a series of numbers);
    • logs of when you downloaded HuYu, when you registered, when you used it, how long you used it for, how many times you scanned receipts, how many times you took part in surveys, and the parts of HuYu that you use and don't use;
    • whether you signed up using your Facebook or Google account;
    • your profile photo, username and email address if you sign up using your Facebook or Google account;
    • app version, foreground or background state (if it's visibly open, or running in the background);
    • the app store you installed the app from and store referral data on how you navigated to HuYu; and
    • interactions with advertisements for HuYu.
  • Phone data:
    • Phone type (for example, iPhone or Android phone);
    • IMEI number (unique device identification number);
    • Mobile operating system (such as Apple OS or Android OS); and

We automatically collect and process the above data through third-party service provider tracking technology – as you download, register and interact with HuYu, our third-party service providers Appsflyer and Google Analytics for Firebase, will automatically collect and process some of the information described above using tracking technology. See paragraph 5 for more information about our third-party service providers.

4. How we use your data and the legal basis for processing it

We use your data to do the following things and, unless we say something different below, the legal reason we use it is for our legitimate business interests as a data science company:

  • to register you as a HuYu user - we do this to perform the contract we have with you;
  • to create aggregated insights and segmentations about HuYu users’ preferences, opinions and shopping behaviour. This will involve combining the data about all HuYu users so that we can identify trends and patterns of behaviour. When we do this, we may analyse all of our HuYu users or segments of our HuYu users. As part of this process, your data will be anonymised so we can no longer identify you or your data within the resulting aggregated insights and segmentations. We will use the insights and segmentations to create reports which we sell to our clients such as retailers and brand-owners. These will only ever report insights about all of our HuYu users or segments of HuYu users, not individuals;
  • to understand your interests by analysing your online behaviour i.e. the websites you visit and how you spend your time online. The data helps our clients understand the best ways to communicate with their customers – we do this if you have given your consent to share this data with us;
  • to issue your points and facilitate points redemption. We also keep a record of points redemption (including the date on which you exchanged your points, the number of points you exchanged, the reward you selected and the date on which your reward was sent to you) – we do this to perform the contract we have with you;
  • to understand and track how users interact with HuYu so we can improve your user experience and develop new features and functions based on how you and other users are using HuYu;
  • to invite you to take part in HuYu surveys that will be of interest to you, analyse your responses and create aggregated insghts. When we do this, we look at all HuYu users responses together or segments of users, not just yours;
  • to invite you to take part in HuYu surveys which are requested by our clients. We will analyse your responses, create aggregated insights and, in this case, the insights will be shared with our clients;
  • to invite you to take part in HuYu focus groups and feedback sessions;
  • to respond to your questions or comments – we do this to perform the contract we have with you;
  • to send you emails, for example to let you know about new HuYu features or surveys, to remind you about HuYu activities or request feedback – we do this if you have given your consent by opting in to receive these communications;
  • to send you notifications, for example to let you know about new HuYu features or surveys, to remind you about HuYu activities or request feedback – we rely on a ‘soft opt-in’ to send you these so you will receive these if you have not opted out via the notifications page and via your device settings;
  • to send you service communications to let you know about something important relating to HuYu or your use of HuYu, for example we may need to notify you about issues we’re experiencing with the app, essential updates or upgrades, updates to our privacy notice or terms of use and any other legal updates – we do this to perform the contract we have with you and to comply with a legal obligation;
  • to take the appropriate steps if you violate the HuYu Terms and Conditions; and/or
  • to take action against you if you do something illegal – we do this to comply with a legal obligation.

Your data will not be used to advertise or market third party products or services to you.

If you have questions about or need further information concerning the legal basis on which we collect and use data about you, please contact us (See paragraph 12).

The insights we share with our dunnhumby clients (brands and retailers) will never contain your personally identifiable data or enable our clients to identify you because the data we share is always aggregated.

We may disclose your data to our group companieswho operate around the world to help us make HuYu available to you or to create and deliver insights to our clients.

We will disclose your data to third party services providers who help us provide HuYu, for example by hosting it, enabling certain features or functionality, or by providing ancillary services such as data analytics, data storage, support and maintenance or security technology.

We may share your data with any other person if you consent to us sharing it with them.

6. How does dunnhumby keep my data secure?

We use appropriate technical physical and organisational measures to protect the data that we collect and process about you. The measures we use are designed to provide a level of security appropriate to the risk of processing your data. Specific measures we use include restricting access to staff on a need to know basis and ensuring our staff receive data protection training, treat your data in confidence and are required to comply with our data protection policies and procedures. When we share your data with the other organisations listed in section 6, we will put appropriate safeguards in place to protect your data including putting contracts in place and making sure that they treat your data confidentially.

7. International data transfers

The data held by HuYu is stored using Google Cloud Platform's servers in Belgium.

Our group companies and third party service providers operate around the world. As a result, your data may be transferred to, and processed in, countries other than the country you are in. These countries may have data protection and privacy laws that are different to the laws of your country and, in some cases, may not be as protective.

We have taken appropriate safeguards so that your data is protected in the way we've explained in this Privacy Notice. These include implementing the European Commission’s Standard Contractual Clauses for transfers of data between our group companies, which require all group companies to protect data they process from the EEA in accordance with European Union data protection and privacy law. If you're wondering what the EEA is, it's each country in the European Union plus Norway, Iceland and Liechtenstein.

If you would like to see our Standard Contractual Clauses, please contact us using the details in the How to Contact Us section below and we would be happy to provide a copy. We have similar safeguards in place with our third party service providers and partners, if you would like further details about these, please contact us (See Paragraph 12).

8. Data retention

The data HuYu holds on you (both the raw data taken from your receipts and the insights we create from those receipts and survey responses) will be kept for 117 weeks and then deleted, save for e-receipts where the raw data will be kept for 7 days and then deleted.

When you send us any receipt (paper or email), we only require the following raw data to create the insights:

  • Retailer name
  • Order date
  • Order time
  • Spend total
  • Item name
  • Item quantity
  • Spend on item
  • Promotions
  • Product category

We will delete the raw data, but once data about you and other HuYu users is aggregated to create insights and trends data, your data will be anonymised and we won't be able to identify you or separate your data from other HuYu users. Because you are no longer identifiable, this data is no longer personal data and will be retained indefinitely.

We will keep information and records about you for as long as you're a HuYu user and for 117 weeks after you stop being a HuYu user (for example, to deal with any claims or complaints which you may make and to manage any requests you make to exchange your HuYu points for rewards).

If you have given us your phone number for the purposes of participating in a focus group or feedback session, we will only keep your phone number for the period necessary for the purposes of arranging the focus group or feedback session you have opted in for. Unless you request that we delete it earlier, your phone number will be deleted after the focus group or feedback session has taken place.

9. Minimum age of HuYu users

HuYu is for people who are 18 or over. If you are under 18, please do not download or use HuYu.

10. Your data protection and privacy rights

When you use HuYu, we will use your data as explained in this Privacy Notice, but you will always have the following rights over your personal data:

  • You can access, correct, update or request deletion of your data, by contacting us using the contact details provided under the “How to contact us” (see paragraph 12). If for any reason, you no longer wish to use HuYu and wish to close your account with us, you can delete the HuYu app at any time from your phone/tablet or you can get in touch with us using the “How to contact us” (See paragraph 12), sso that we can delete your account data. Please note that there are circumstances where the law allows us to retain your data – for example, where the law requires us to keep a copy of your data or where we need it to bring a claim or to defend ourselves against a claim. An example of this would be a record of the rewards which we have provided to you in exchange for your reward points – we would need to keep a record of this in case you felt that we hadn't provided the right rewards.
  • You can object to processing of your data, ask us to restrict processing of your data or request portability of your data. Again, you can exercise these rights by contacting us using the contact details provided under the “How to contact us” (See Paragraph 12). Please note, certain features and the third-party service provider tracking technology used by Firebase and Appsflyer cannot be turned off for individual users so you will need to cease use of HuYu if you wish to exercise your right to object to processing or restrict processing carried out through the relevant feature or tracking technology.
  • You have the right to opt-out of marketing communications we send you at any time. You can exercise this right as follows:
    • Notifications: by switching off notifications via your device settings and via the Notifications sections of your Account (Note: the device settings override in-app settings so, if you switch off in-app but not via your device settings, you will still receive notifications).
    • Emails: by switching off the toggle in the Notifications sections of your Account or by clicking on the “unsubscribe” link in the marketing e-mails we send you.
    Where we use your data with your consent, then you can withdraw your consent at any time. If you withdraw your consent, this means that we can't use your data for that purpose any longer, unless we have another lawful ground for us to use it (for example, service communications). It also won't affect our use of your data before you withdrew your consent.
  • You can complain to an information authority about the way we have used your data. For more information, please contact your local authority. (Contact details for authorities in the European Economic Area, Switzerland and certain non-European countries (including the US and Canada) are available at

We will respond to any request which you send to us and we will manage your request in accordance with applicable laws.

11. Updates to this Privacy Notice

We want HuYu to get bigger and better and for you to get more out of HuYu in the future, so we will introduce more features. As HuYu evolves, we may collect more data about you and we may use your data in different ways – we will always be completely transparent with you about the data we collect and what we will do with it – we will send you updates to this privacy notice as we introduce new features where they change the data we collect about you or the way we use it.

We will also update this Privacy Notice as things change around us – this may be due to change in law, a change in technology – or it may be due to change in our business. When we update our Privacy Notice, we will take appropriate measures to inform you, consistent with the significance of the changes we make. We will obtain your consent to any material Privacy Notice changes if and where this is required by applicable data protection and privacy laws.
