How we collect data

We collect data about you in the following ways:

Provided by you (Directly):

  • In person, when you speak to one of our staff or volunteers
  • Through a telephone call, either where you call Plaid Cymru or we call you
  • On paper, such as if you return a printed survey or a reply slip on a leaflet
  • Digitally, such as if you fill in a form on a website or interact with the Party online via our website or social media platforms
  • When you offer or ask about volunteering, or take part in party activities
  • When you enter into a transaction with the Party, such as donating, joining, purchasing a product or paying for an event
  • When you consent to receiving marketing emails etc
  • When you attend a conference or campaign event

Third Party Sources (Indirectly):

  • Indirectly from publicly accessible sources or other public records, including the full electoral register to which the Party is legally entitled
  • CCTV, if you visit Plaid Cymru Headquarters

Plaid Cymru is legally entitled to, and receives, the electoral registration records of all electors in Wales. We receive an updated version of these every time an update is published, which is usually every month.

We collect data with the intention of using it primarily for political activities.

Plaid Cymru uses the data that we collect about you to build a picture of public opinion. We do this to:

  • understand the matters and issues that are likely to be of relevance and significance to you and better inform our future policies,
  • decide whether we send you our campaigning materials,
  • select what campaigning material we send to you and which messages we put on it,
  • evaluate whether we think you are likely to vote and for whom you will likely vote for during an election or a referendum.

How we use your information and why we are allowed to use it

How your data is used is protected by law and we only use your data where we have an acceptable reason for doing so. The reasons we process your data are:

  • In pursuit of an activity that supports or promotes democratic engagement (Public Interest), or
  • When it is our legal duty (legal obligation), or
  • When you provide consent (consent), or
  • In order to fulfil a contract with you (contract)

The law restricts the processing of what is termed “special categories of personal data”. The work of Plaid Cymru is deemed to be of substantial public interest and therefore we are permitted to process special categories of personal data relating to your political opinions and voting intentions.

The table below lists examples of how we use your data and our justification and legal basis for it.

We are committed to respecting your rights over your data and in some circumstances, we will have a legal duty to continue to process your data even where you have exercised one of your rights. For example, if you request that we stop processing your data for purposes of direct marketing then we justify keeping a record of this request to ensure that your wishes are respected.

Data Processed with your Consent

Where we use consent as our legal basis for processing your data, or process special categories of your data based on your explicit consent, you have the right to withdraw your consent at any time. This does not affect our right to process your data before you decide to withdraw your consent.

Who we share your data with:

We will never sell your data but sometimes it is necessary to share your information with our service providers and data processors. Data is only ever shared where we have a justification and when the law allows us to do so.

We share data with:

  • Business associates and professional advisers
  • Suppliers
  • Service providers
  • Financial organisations – such as credit card payment providers
  • Elected representatives
  • Regulatory bodies
  • Market researchers
  • Law enforcement agencies

Where we use a service provider to process your data on our behalf we will ensure that this processing is governed by a legally enforceable contract which sets out their responsibilities for protecting your data and your rights.

Transferring your data outside of the European Economic Area

Some of our service providers are located outside of the European Economic Area (EEA) and therefore it may be necessary to transfer your personal data outside of the EEA. Where we do transfer your data outside of the EEA we will make sure that it is protected in the same way as if the data was inside the EEA.

We will use one of the following safeguards to ensure this:

  • Where the European Commission has issued an adequacy decision determining that a non-EEA country or organisation ensures an adequate level of data protection.
  • A contract is put in place with the recipient of the data obliging them to protect the data to the same standards as the EEA.
  • The transfer is to an organisation that complies with the EU-US Privacy Shield.

How long we retain your data for:

We constantly review the data that we hold and regularly review its relevance and our need to hold onto it. Whilst we do not set finite periods for data retention we use several factors to determine whether we need to hold onto the data. Factors we take into consideration are:

  • Retention periods as required by law – for example Plaid Cymru is under a statutory duty to retain financial information for a period of 6 years,
  • The purpose for which the data was provided or obtained,
  • Our legitimate interests in holding onto your data,
  • Whether holding onto your data will infringe your rights over your data,
  • Legal and regulatory obligations that may require reference to your data,

How we protect your data:

The security of your data is paramount to the Party and as such we ensure that appropriate technical and organisational measures are in place to protect it. We constantly review our measures to ensure that your data is protected from any threats that may emerge.

Your rights over your data 

Right of access to your data: You have the right to request a copy of your personal information that we hold. This is commonly known as a Subject Access Request. We follow the ICO’s “Subject Access Code of Practice” when dealing with requests for access to personal data. You can read this code by visiting

Right of rectification of your data: You have the right to request that inaccurate or incomplete information that we hold about you is corrected.

If you need to correct the information you can do so by emailing [email protected].

Right to be forgotten: In certain circumstances you can ask for the data we hold about you to be erased from our records. When we do so, we keep the bare minimum of your information to continue to respect your wishes when your personal data is next provided to us by a local authority, which is at least annually.

Right to restriction of processing: You have the right to request that we restrict the processing of your data where you are contesting the accuracy of the data or when the data has been unlawfully processed.

Right to object: You have a right to opt out of your data being used for direct marketing. If we process your data based on “a task carried out in the public interest” then you have the right to object to us using your data in that way. This right is not absolute, and we may continue to process your data if we can demonstrate compelling legal grounds for the processing.

Opt Out: We provide you the opportunity to opt-out of receiving communications from us easily and promptly. Please email [email protected] if you would like to unsubscribe from receiving updates or if you would like us to permanently delete any personal information the party holds about you.

Automated individual decision-making, including profiling: We may use computer software to make decisions about you or to create a profile about you. You have the right not to be subject to such a decision or to that profiling where it creates legal effects concerning you or where it significantly affects you. None of our processing falls within that category.
