Privacy policy

To process your data in the UK or EEA we must have a lawful basis to do so. Our legal basis for collecting and using your information (described below) will depend on the personal information concerned and the specific context in which we collect it.

We do a lot of different work, so there are times when there are more rules that say we have to use your personal data to do our work, and we can do this without asking you first. We will process your personal data where:

• You have given consent to the processing of your personal data for one or more specific purposes.
• It is necessary for performing a contract to which you are a party or to take steps at your request prior to entering a contract.
• It is necessary for compliance with a legal obligation to which we are subject.
• It is necessary to protect your vital interests.
• It is necessary for performing a task carried out in the public interest or exercising an official authority vested in us.
• It is necessary for the purposes of the legitimate interests pursued by us or by a third party, except where such interests are overridden by your interests or fundamental rights and freedoms which require protection of personal data.

You can disable the collection of first-party identifiers for each instance of our apps that you have downloaded at any time in the settings pages of the app.
• Service providers such as Meta and Google will use Pseudonymised data to create marketing lists. These lists can then be used to target users more closely and improve relevancy of advertising. Users will be profiled into “Lookalike audiences” (Lookalike audiences are customers who have the same interest such as hiking or dog walking and may be interested in the same promotional content) which can be used to improve the marketing audience.

Specifically, our website servers are located in the UK, EEA, and Australia, and our third-party service providers and partners operate in UK, EEA, USA, and Australia. This means when we collect your personal information, we may process it in any of these countries.

However, we have taken appropriate safeguards to require your personal information remains protected in accordance with this Privacy Policy. We have implemented appropriate safeguards with our third-party service providers and partners and further details can be provided upon request.

Once it is within our control, we will do our utmost to ensure your personal data is processed in a way that ensures appropriate security from unauthorised or unlawful processing, accidental loss, destruction, or damage.

We have put in place procedures to deal with any suspected personal data breach and will notify you and any applicable regulator of a breach where we are legally required to do so.

To determine appropriate retention periods for personal data, we consider the amount, nature, and sensitivity of the personal data, the potential risk of harm from unauthorised use or disclosure of your personal data, the purposes for which we process your personal data and whether we can achieve those purposes through other means and the applicable legal requirements.

In some circumstances we may anonymise your personal data (so that it can no longer be associated with you) for research or statistical purposes. We may use or store this information indefinitely without further notice to you.

In some circumstances you can ask us to delete your data: see Right to Erasure below for further information.

Withdraw Consent – Where we are using your personal information based on your consent, you have the right to withdraw that consent at any time.

Right to be Informed – You have the right to be told how your personal information will be used. This Privacy Policy document, and shorter summary statements used on our communications, are intended to be a clear and transparent description of how your data may be used.

Right of Access – You can write to us asking what information we hold on you and to request a copy of that information. This is called a Subject Access Request (SAR). We have one calendar month to respond to you once we are satisfied you have rights to see the requested records and we have successfully confirmed your identity. Details on how to submit a Subject Access Request if you are in the UK or EEA can be found on our data protection page.

Right of Erasure –You have the right to be forgotten (i.e. to have your personally identifiable data deleted). However, we may not always be able to comply with your request of erasure for specific legal reasons, which will be notified to you. In some cases, we may recommend we suppress you from future communications, rather than data deletion, particularly if you have purchased an item from our e-commerce shop which comes with a warranty. Our Customer Services Team will be happy to advise you.

Right of Rectification – If you believe our records are inaccurate you have the right to ask for those records concerning you to be updated. This enables you to have any incomplete or inaccurate data we hold about you corrected. We may need to verify the accuracy of the new data provided to us.

Right to Restrict Processing – In certain situations you have the right to ask for processing of your personal data to be restricted because there is some disagreement about its accuracy or legitimate usage.

Right to Data Portability – Where we are processing your personal data under your consent, the law allows you to request data portability from us to another service provider. This right is largely seen as a way for people to transfer their personal data from one service provider to another. We will provide to you, or a third party you have chosen, your personal data in a structured, commonly used, machine-readable format. Note that this right only applies to automated information which you initially provided consent for us to use or where we used the information to perform a contract with you.

Right to Object – You have an absolute right to stop the processing of your personal data for direct marketing purposes. Simply contact our Customer Service Team and they will amend your contact preferences or alternatively if you have an OS Maps or shop account you can update your details in your Preference Centre.

Right to object to automated decisions – In a situation where a data controller is using your personal data in a computerised model or algorithm to make decisions “that have a legal effect on you,” you have the right to object. This right is more applicable to mortgage or finance situations. We do not undertake complex computerised decision making that produce legal effects.

We will only ask for information relevant to your query, which may include:

• Name
• Email address
• Telephone number
• Address
• Any reference numbers we have provided.

It is important you do not provide any sensitive information that is not directly relevant to your queries such as bank details or medical information. All data is passed to third parties who support this service.

In this instance, consent is obtained by The Duke of Edinburgh’s Award charity when a parent/guardian gives consent for a child to sign up to the DofE programme and are informed of third-party services used to facilitate participation.

We will use the information collected below to enable access to the OS Maps Web App Service and to send any service-related and/or downtime emails.

Information for Californian users

These California subsections apply only to “personal information” about California residents, as that term is defined in the California Consumer Privacy Act (“CCPA”), and they supplement the information in the rest of our Privacy Policy.

Collection and Disclosure of California Personal Information During Past 12 Months

The chart below provides more detail on our disclosures of California personal information during the 12 months leading up to the effective date of this Privacy Policy:

CCPA “Sale” of California Personal Information

The CCPA requires businesses that “sell” personal information, as the term “sell” is defined under the CCPA, to provide an opt-out from such sales. Ordnance Survey does not “sell” personal information as that term is commonly understood or within the CCPA definition of the term.

California Privacy Rights

If you are a California resident, California law may permit you to request that we:

• Inform you of the categories of personal information we have collected about you in the last twelve months; the categories of sources of such information; the categories of personal information that we disclosed about you for a business purpose; the business or commercial purpose for collecting your personal information; and the categories of third parties to whom we have disclosed personal information for a business purpose.
• Provide access to and/or a copy of certain information we hold about you.
• Delete certain information we have about you.

You also may have the right to receive information about certain “financial incentives” that we may offer to you (if any).

Certain information is exempt from such requests under applicable law. For example, the CCPA has significant exceptions for certain B2B data.

To request to exercise your CCPA rights, please submit your request via Contact our Customer Services team or by emailing DPO@os.uk

For security and legal reasons, we may not accept requests that require us to access third-party websites or services. We do not respond to browser-based do-not-track signals or similar mechanisms. We can take steps to verify your identity before responding to your request, which may include requesting that you respond to an email that we send to you, requiring you to login to an account (if you have one) or otherwise verifying your name, email address, or other information that will help us to confirm your identity.

If you are an agent making a request on behalf of a consumer, you must verify that you are authorised to make that request, which may include requiring you to provide us with written proof that satisfies CCPA requirements, such as an appropriate letter signed by the consumer or a power of attorney. We also may require the consumer to verify their identity directly with us.

Non-discrimination

You have the right not to receive “discriminatory treatment” (within the meaning of the CCPA) for the exercise of the privacy rights conferred by the CCPA.

Information for Nevada users

Under Nevada law, certain Nevada consumers may opt out of the “sale” of “personally identifiable information” for monetary consideration to a “data broker” (as such terms are used in Nevada privacy law) or other person. We do not engage in such activity as of the effective date of this Privacy Policy. However, Nevada users may submit a request to opt out of any potential future “sales” under Nevada law by sending a request to Contact our Customer Services team or by emailing DPO@os.uk

We may take steps to verify your identity and the authenticity of the request. Once verified, we will maintain your request in the event our practices change.
