whatwords Limited (“what3words”, “we” or “us”) is committed to protecting your personal data and respecting your privacy.

This Privacy and Cookies Policy (this “Policy”) details the personal data we collect in relation to you and explains how we handle that personal data.

In respect of the processing activities described in this Policy, what3words Limited of Studio 301 Great Western Studios, 65 Alfred Rd, London, England, W2 5EU, UK is your data controller.


We may collect and process the following personal data about you:

(A) Information you voluntarily provide when you contact us

You may provide us with your name, address, telephone number and email address in the following instances:

● if you contact us by phone, email or through what3words.com (the “Website”) or the Apps (as defined in the Terms and Conditions), to report an issue or for any other reason. We may keep a record of that correspondence in case we need to contact you in relation to the issue for which you contacted us, for operational performance improvement, to resolve a dispute, and/or nuisance caller management;

●when signing up to complete one of our surveys. Please note that if we do collect your name and email address when you complete a survey for us, this will typically be so that we can contact you in the event that we offer a prize to a lucky winner. We will endeavour to anonymise any surveys retained on our systems within 30 days of the survey closing; or

●when you sign up to our Squares programme, so that we can send you goodies by post. If you choose to attend an event with us, we may also collect your image (by way of either photograph or video). Please do let us know (either by email in advance or on the day at the event) if you would prefer that your image is not captured and we will let our camera operators know.

If you choose to attend an event with us, we may also collect your image (by way of either photograph or video). Please do let us know (either by email in advance or on the day at the event) if you would prefer that your image is not captured and we will let our camera operators know.

If you choose to download one of the what3words toolkits available on our Website, we will ask you for your email address and company name. We will use your email address in order to send you your toolkit and your company name to conduct internal analysis on how the toolkit is being used. If you indicate that you are happy for us to do so, we may use your email address to contact you to ask for feedback on how you are using the toolkit (to enable us to make improvements to our products and services in the long term).

(B) Information we collect about you and your device when you interact with our services

If you choose to become a registered user of our services, we will process your name, contact details, and email address, as well as your what3words password. However, you are not required to provide us with this information to use the Website or our Apps.

Registered users in some jurisdictions are also presented with the opportunity to use the “Saved Locations” functionality within our Apps. This means you can save specific what3words addresses and label them (e.g.“home” or “work”). If you choose not to use the Saved Locations feature, that’s perfectly fine. You can also choose to delete your saved locations at any time within the App.

When you use the Website and/or the Apps to access our services, we may use technology such as (but not limited to) that provided by Google (Google Analytics and Google Firebase) and Matamo (see Section 3 below) to collect information about your visit to our Website and use our Apps. In essence, Google Analytics and Firebase enables us to analyse how you and others interact with our Website and Apps. The information we collect may include:

●user preferences;

●which 3 word address locations you searched or landed on the App or Website (including anything you type incorrectly into the search bar);

●user content including photographs, videos and other content that you choose to share on our Website or Apps and any associated content including comments that you post to our Website and/or Apps;

●which pages you visited on the Website;

●analytics information in relation to your interactions with the newsletter (e.g. click rates); and

●if you elect to join our squares community (subject to our Squares Terms), we may hold any personal data you choose to share within any social media group (including Facebook and Slack) set up by us for the purpose of engaging the community. In addition, if you choose to share your uniquewhat3words download link, we may also track the number of downloads which resulted from that link.

The reasons we collect this data are:

●to ensure that content from our site is presented in the most effective manner for you and for your device;

●to improve the services we provide in the short-term, for example by providing you with more relevant search results;

●to improve the services we provide over the longer-term by understanding how you and other users interact with our services;

●serving recommendations to you around those functionalities of the App or Website which are most relevant to you, based on your use of those platforms;

●to notify you about any important changes to our services;

●to ensure that we continue to provide relevant information to recipients of our newsletters; and

●(for the audio files only) to permit audio to text transcription through automated methods, after which such files are discarded.

We may utilise cookies to achieve some of the above. Furthermore, we may use pixel tags within our emails in order to measure the success of our direct marketing campaigns (including our newsletter), and to compile statistics about usage of the services. More information on the cookies we utilise and why is set out in the Cookies section below.

If you are a business which uses the what3words application programming interface (“API”), we collect the following pieces of personal data in respect of each API call made:

●content of the API call (for example, the three word address searched);

●timestamp; and

●IP address from which the call was made.

The reasons we collect this data are:

●to deliver the GPS co-ordinates which correspond with the 3 word address searched; and

●to analyse and better understand how our API is being used.

(C) Information we collect about you when you contact us for business to business marketing purposes

As a prospective (or existing) business customer of what3words we may collect:

●your name, email address and telephone number;

●the name of the business you own or represent and your business title; and

●the address of the business you own or represent.

We may collect this information directly from you, or from publicly available sources such as LinkedIn and, subject to any local law restrictions, may use this information to contact you directly for the purpose of informing you about our products and services and discussing any potential partnership. Should you not wish to be contacted by us after we have reached out to you, please do not hesitate to let us know.


In certain jurisdictions, such as those located within the European Union, we are required to establish legal bases to process your personal data. We have identified our legal basis for processing in respect of each of the processing activities set out below:

(A) Responding to correspondence instigated by you

Where you contact us for any reason, we will process any personal data provided by you for the purposes set out under Section 1 (A) above. On balance, we consider that we have a legitimate interest in processing your personal data for those limited purposes and that it is necessary to do so.

(B) Photographing and recording our events

We consider that we have a legitimate interest in recording the events we host (by way of either photograph or video). As set out above, please do let us know (either by email in advance or on the day at the event) if you would prefer that your image is not captured and we will let our camera operators know.

(C) Administering your what3words account

When you create an account with us you sign up to our Terms and Conditions. We process your name, contact details, and email address (as well as your what3words password) so that we can provide you with the service we commit to under those Terms and Conditions. We also store your saved locations within along with your account details so that you can access those saved locations each time you open the App.

(D) Effectively manage our business and improve our services

Where we have determined that, on balance, our legitimate interest in using your personal data to effectively manage our business and improve our services does not outweigh your own rights and freedoms we rely on legitimate interests as the legal basis for processing that personal data. This covers the analysis of the information collected through technical means, as set out under Section 1(B) above. We will always seek to ensure that any data used for analysis purposes is encrypted and/or aggregated, where doing so would not impact the specific purpose we are trying to achieve. For example, it may be necessary to use an un-hashed version of your device ID in order to ensure that the notifications you receive within the App about a new feature are relevant to you.

(E) Electronic direct marketing activities (end users)

Where we have your express, opt-in consent we may contact you by email or other electronic means for the purpose of providing you with marketing information (including our newsletters) relating to our products and services.

We will never share your contact details to third parties to allow them to contact you for direct marketing purposes.

5. Keeping information secure
