At One Stop, we’re working hard to serve our customers, communities, and planet a little better every day. Looking after the personal data you share with us is a hugely important part of this. We want you to be confident that your data is safe and secure with us and understand how we use it to offer you a better and more personalised shopping experience.

1. Overview (including what is personal data and why it’s important)

When you shop or communicate with One Stop, we collect and create personal data about you.
This policy does the following:
• sets out the different ways you interact with us and the types of personal data that we collect
• explains the reasons why we use the data we collect
• explains when and why we’ll share personal data within One Stop, the wider Tesco Group to which we belong, and other organisations
• explains the rights and choices you have when it comes to your personal data (including your marketing and cookie preferences).


2. What does One Stop know about me?

One Stop will collect and create different types of data. These may include the following broad types.

Aggregated Data
We try and remove personal data we don’t need. If we remove enough personal data, it becomes anonymous. This means that you can’t be identified. We might also take data we hold and remove certain information and replace it with other non-identifying information, such as an ID number or reference number. This is an extra technique we use to protect data. We normally use these techniques to look at statistical or demographic data.

Identity and Contact Data (name, address)
This is information that helps us identify who you are and how we can contact you. This includes your name, title, address, email, and telephone number.

Financial and Transactional Data (purchase information, banking and payment details)
This is information about your bank account and payment card details, as well as information about your purchase of a product or service from us. This includes when, where, what and how you purchased that product or service.

User and Interaction Data (how you interact with services online and in-store)
User data is information collected about you as a user of our stores and services. This may include where you engage with One Stop in a survey; provide feedback on your shopping experience; are captured by CCTV or other camera technologies.
We’ll also collect information about you that allows us to create an analysis of you as a customer. This is to better judge what offers and services to offer you.
Interaction data is information about how you interact with our services, namely what you click on and interact with on our sites or apps.

Marketing Data
This is information about your marketing preferences and your interaction with online marketing. For example, we can see when you open marketing emails from One Stop (you can opt out of marketing at any time by telling us). This also includes if you interact with adverts from One Stop while browsing the internet.

Location Data
In some cases, a related app might ask for your location information to better serve you information about your local store. If we’re collecting this data, we’ll make you aware of this at the time.

Technical Device Data
This is information about the device you use to access our sites and app. This could be information that identifies your device, its operating system, internet address, your sign-in data, browser and plug-ins, location, where you came to our site from and where you go when you leave, as well as how often you visit. If you use our in-store WIFI, we’ll collect information about where and when you accessed our network. This is done via the use of cookies which is covered further down in this notice.

3. Why do you need to know this about me?

We’ve carefully considered the reasons for collecting and/or creating this data. Here’s a summary of when and why we believe it’s appropriate.

To make our services available to you
This means that processing your personal data allows us to:

i. manage any accounts you may hold with us
ii. process interactions

Why do we process your personal data in this way?

We need to process your personal data so that we can manage your customer accounts, provide you with the goods and services you may wish to buy, and help you with any queries or questions.

Why we’re using this data (legal basis)

• Contractual necessity – at the time we collect it (purchase data, contact details, delivery/collection details)
• Legitimate interests – following fulfilment of your order

We won’t be able to provide you with your products or services if you don’t provide us with this data.

To manage and improve our day-to-day operations

i. Help to develop and improve our product range, services (digital and physical), stores, information technology systems, know-how and the way we communicate with you.

Why do we process your personal data in this way?
We rely on the use of personal data to carry out market research and internal research and development. It also helps us to improve our information technology systems (including security), our product range, services and stores. This allows us to serve you better as a customer.

ii. Detect and prevent fraud or other crime.

Why do we process your personal data in this way?
It’s important for us to monitor how our services are used to detect and prevent fraud, other crimes and the misuse of services. This helps us to make sure that you can safely use our services.

Why we’re using this data (legal basis)
• Legitimate interests

To personalise your One Stop experience

i. Manage and improve our website and any mobile apps.

Why do we process your personal data in this way?
We use cookies and similar technologies on our website to improve your experience.

Some cookies are necessary so you shouldn’t disable these if you want to be able to use all the features of our websites and mobile app. You can disable other cookies but this may affect your experience.

ii. Use your online browsing behaviour, as well as your in-store and online purchases (including Clubcard transactions), to help us better understand you as a customer and provide you with personalised offers and services.

Why do we process your personal data in this way?
We use basic data about your general shopping habits (and those of similar households) to group customers into different segments such as ‘Tesco families’. This allows us to personalise our offers and services for you (including in our marketing communications).

iii. Provide you with relevant marketing communications, relating to our products and services, and those of our suppliers, retail partners and the wider Tesco Group.

If we or our retail partners run online advertising, this may be displayed on websites across the Tesco Group, non-Tesco websites and other media platforms (including Sky AdSmart and platforms such as Facebook, Snapchat and TikTok).

We may also measure the effectiveness of this advertising. To do this, we may use certain basic data about your in-store and online purchases (for example if you bought a particular product that was featured in an advert). However, we limit this to what is necessary, and it is always obscured or anonymised to protect your identity. When we share your data in this way, it won’t be used by those platforms for their own purposes and will be deleted shortly after.

Why do we process your personal data in this way?
We want to make sure that we provide you with marketing communications, including online advertising, that are relevant to your interests. To achieve this, we measure your responses to marketing communications relating to products and services that we and our retail partners offer. This means that when you’re offered products and services, they best meet your needs as a customer.

Why we’re using this data (legal basis)
• Legitimate interests
• Consent (where we need this from you)

To contact and interact with you

i. Contact you about our services, for example by phone, email or post, or by responding to social media posts that you’ve directed at us.

Why do we process your personal data in this way?

We want to serve you better as a customer, so we use personal data to provide you with clear information or help in response to your communications.

ii. Manage promotions and competitions you take part in.

Why do we process your personal data in this way?

We need to process your personal data, so that we can manage the promotions and competitions you choose to enter.

iii. Invite you to take part in and manage customer surveys, reviews and other market research activities carried out by the Tesco Group and by other organisations on our behalf.

Why do we process your personal data in this way?

We carry out market research to improve our services. However, if we contact you about this, you don’t have to take part in the activities. If you tell us that you don’t want us to contact you for market research, we’ll respect your choice. This won’t affect your ability to use our services or your Clubcard. If this research is through our Tesco Home Panel service, we’ll give you additional information about how we use your data when you sign up for this service.

Why we’re using this data (legal basis)

• Legitimate interests

To resolve legal claims or disputes

Why do we process your personal data in this way?
This might be needed if you have an accident or there’s an incident at our stores, for example. This could include medical reports.

Why we’re using this data (legal basis)
• Bringing or defending legal claims

To use CCTV to protect our stores to prevent and detect crime and anti-social behaviour

If you park in our car parks, we may use Automatic Number Plate Recognition Technologies (ANPR) to identify if your vehicle has complied with our parking rules. Where there’s a security or claim incident involving a vehicle, we may use ANPR to assist in our investigation into those incidents.
We also use body-worn cameras to protect staff and customers, and record footage in the same way as we do with other forms of CCTV.

Why do we process your personal data in this way?
In order to protect our business, the local community, customers and colleagues.
Why are we using this data (legal basis)
• Legitimate interests
• Exercising our legal rights

4. Why are you allowed to use my data in this way?

Whenever an organisation uses data, they must have a reason to use it. The law gives certain reasons for the use of data and One Stop will always use data according to one of those reasons. In the section ‘Why do you need to know this about me’ we’ve stated the different reasons that we might hold data.
In this section, we explain why we think those reasons are suitable and what this means for you.
There’s often a focus on consent to use personal data but, in many circumstances, consent wouldn’t be appropriate. For example, a shoplifter withdrawing consent to be filmed with CCTV would increase risk to you and our colleagues; or a customer withdrawing consent to process their payment information.
Therefore, in many situations, One Stop relies upon two other legal reasons. The first, relates to needing data to fulfil a ‘contract’ with you. At the point of you buying goods and services from One Stop, a contract is created and any data we collect to allow us to deliver or provide those services or goods can be used and kept to make sure we fulfil our contract. The second is a concept called ‘legitimate interests’. This is when there are legitimate and reasonable reasons One Stop might collect and use data. For example, collecting information through your Clubcard is beneficial to both Tesco and you because we can understand what products you’re interested in and make sure the products we offer match that need.

Our use of your personal data when based on ‘legitimate interests’ are to:
• meet our customers’ needs, including delivering our products and services
• promote and market our products and services, and those of our retail partners, media partners and service providers
• service your account (such as your Clubcard account), manage complaints and resolve any disputes
• understand our customers including their patterns and behaviours, as well as their likes and dislikes
• protect and support our business, colleagues, customers and shareholders
• prevent and detect anti-social behaviour, fraud and other crime
• test and develop new products and services as well as improve existing ones.

We’ve assessed these fundamental reasons against the fundamental rights and freedoms provided to you under the law and balanced them up against the benefit both you and Tesco might receive from this data being used.

5. Data collected from third parties

We may also use personal data from other sources, such as specialist companies, media partners, retail partners and public registers (such as the electoral register).
When we work with specialist companies that provide us with personal data about you, they’ll have told you about this data sharing at the time it was collected. We use this and our own data to better understand our customers.
We also use this personal data to make sure we have up-to-date details about you. We don’t give personal data we’ve collected or created from you back to these companies.


6. How does One Stop look after my data?

We know how important it is to protect and manage your personal data. This section sets out some of the measures we have in place.
• We make sure staff are trained and rules are in place to make sure that data is used properly
• We have physical protections and digital/electronic systems in place to keep what we hold secure
• When data is moved or transferred, we make sure it’s encrypted (scrambled)
• We use computer safeguards such as firewalls and data encryption to keep this data safe when it’s not being moved
• We only allow access to colleagues and trusted partners
• We regularly watch our systems for possible weaknesses and attacks, and we carry out tests (penetration testing) to see what can be improved
• We’ll ask for proof of identity before we share your personal data with you

Your personal data may be transferred outside the UK. It may also be processed by companies outside the UK who work for us (or for one of our service providers). When we do this, your personal data will be subject to appropriate protections. If we do transfer personal data to outside of the UK, it’ll be protected in the same way as if it was being used in the UK. To do this, we use one of the following safeguards:
• We transfer to a non-UK country whose privacy laws ensure an appropriate level of protection for personal data
• We put in place a contract with a third party that means they must protect personal data to the same standards as the UK
• We transfer personal data to organisations that are part of specific agreements on cross-border data transfers with the UK


7. Do you keep my data forever?

We won’t keep your personal data longer than we need to. In most circumstances, this means we won’t keep your personal data for more than 7 years after the end of your relationship with us. For certain data sets, we have the following specific retention periods:
• Customer complaints and feedback will be deleted 4 years after the date of the last communication
• Information you submit when participating in research panels/market surveys will be deleted 3 years after its creation
• CCTV data will be kept no longer than 1 month after its creation.
• Health and safety records (for example, incident reports) will be deleted 7 years after their creation
• Where your personal data is needed because of a serious dispute (such as litigation) or investigation, your personal data will be deleted 7 years after the matter is closed

8. Do you share my data?

We may share personal data with other organisations (including Tesco Group partners as listed below) in the following circumstances:
• to deliver the products and services we have offered to you
• with our retail partners, media partners and service providers (as explained elsewhere)
• to establish, exercise or defend our legal rights or we need to by law (this includes for the purposes of preventing fraud)
• where we restructure, sell, or transfer our business (or a part of it). For example, in connection with a takeover or merger


9. Retail Partners

We work with several retail partners who sell products via Tesco or offer products, services or the ability to earn Clubcard points (Clubcard Reward Partners). We only share personal data that enable our retail partners to provide services you’ve requested.

10. Service Providers

These are organisations that help us to deliver and improve the services we offer to you. For example:
• technology and data services (such as storing, combining and analysing data, and processing payments)
• fulfilment of orders
• legal or other professional services

We only share personal data that enable our service providers to provide their services and they only use it for purposes agreed with us. We may also combine service providers data with data held by Tesco to understand your purchases and interactions with us better.

11. Media Partners

We work with certain media partners in connection with online and other digital media services. They place relevant advertising for us and our retail partners online and through other digital media services. For example, you may see an advert for our products and services when you use a particular platform or watch television through your pay TV account. Examples of our media partners include Facebook, Google, dunnhumby and LiveRamp.

Advertising to “lookalikes”

We work with our retail partners to find potential customers who “look like” our existing customers on platforms such as Facebook and Google for advertising purposes (‘platform’).
To do this, we use information about your general shopping habits (and those of similar households) to create large groups of customers that may be interested in seeing different advertisements of retail partners. If you’re within one of these groups for a given campaign, we may share some basic data about you (and the other customers in the group) with the platform. This is so that the platform can find and show adverts to other users of its platform who have similar interests to you.
The data we share for these purposes is always obscured to protect your identity and is promptly deleted.
You can stop our use of your data in this way by opting out of all marketing from Tesco via your account or unsubscribing from our marketing emails. You can also opt out of being included in a platform’s lookalike audiences directly via them.
