Ways in which we use your personal information 

In some areas of our website and other communications, we ask you to provide personal information that will enable us to enhance your site visit or contact you with information you request or that may be of interest to you, e.g. when you subscribe to our emails. We also collect your details when you email or call us with an enquiry so we can respond effectively to you.

We keep your personal information only for as long as required for the purposes for which it’s supplied. Where your information is no longer required, we will always make sure it is disposed of in a safe and secure manner.

We will only ever use your data in line with our commitments to you. Should you have any concerns about this, please contact our Data Protection Officer.

Our communications 

We will only ever contact you directly using the methods for which you have given your clear consent.

We want to give you as much control over the ways we communicate with you as possible.  If you’d prefer we did things differently – or even stop contacting you entirely – all communications from us will always explain how to opt-out of future communications or change your preferences. Our aim is to give you complete control over how we use your personal data that you share with us.

How we hold and process your personal data 

MHSG holds different data for individuals depending on whether they are members or supporters.  Members are individuals who pay an annual subscription fee to MHSG, and obtain various benefits as members e.g invitations to social events, and discounted prices on goods that we may sell from time to time. Supporters are individuals who have signed up to our email newsletter.  The data held for members and supporters is as follows:

  • For supporters first name, surname and email address are held.
  • For members first name, surname, address, phone number(s), email address, subscription payment method and date of joining are held.

To be compliant with the Data Protection Act 2018, we need to have a legal basis through which we may hold and process your data.  Our legal basis for processing for supporters will be consent. For members the legal basis is legitimate interest.

Sharing your data 

We will never sell your details to other organisations.

If you sign a petition which involves a hand in, for example a petition to be handed in to local government, it may be necessary to include some contact details on the petition hand in. These details will not be shared further. Otherwise we would only disclose your data if we are obliged to do so by law.

Keeping your details up to date 

The accuracy of your information is important to us. If you change your home or email address, or if any of the other information we hold is inaccurate or changes in any way, or even if you simply wish to check that the data you have shared with us is up to date, please contact us by emailing


We place great importance on the security of your personal information and will always take appropriate precautions to protect it.

Even with all these precautions, no data transmission over the internet can be guaranteed to be 100% secure. So, whilst we strive to protect your personal information, we cannot guarantee the security of any information which you disclose to us online and you must understand that you do so at your own risk.

We take care to protect your personal information. We take steps to ensure that access to personal information is restricted to volunteers who need it and that all volunteers who handle personal information are fully trained and kept up-to-date on our data management, security and privacy practices.

Website tracking  

As part of our security measures, every time our website is accessed, we record the date, time and the IP address used. In some circumstances this may mean that record is linked to the personal data you have shared. Sometimes the device used to access the website (e.g. a mobile phone, tablet, laptop) may provide us with further information, such as the device and operating system. Using this information helps us to improve our site performance for example by understanding the times of day and days of week at which we see peak traffic, and to assess the popularity of different areas of the site.

Use of cookies 

Cookies are small pieces of information sent by a web server to a web browser, which enables the server to collect information from the browser.  MHSG uses the WordPress tool for its website and cookies are used by WordPress if a user comments on a blog post.

You may avoid the use of cookies by selecting the appropriate settings on your browser (more details of how to change this will depend on which browser you are using (e.g. Google Chrome or Microsoft Internet Explorer). Please note that if you do this you may not be able to use the full functionality of our website.

Internet-based transfers and processing

The Internet works as a global environment. This means that using it to collect and process personal data often involves the international transmission of data, and on occasions processing of personal data by third parties (including social media companies) outside the European Economic Area.

Although this may happen, you can be reassured that the data will always be held securely and in line with the requirements of UK data protection legislation. However, we want you to be aware that by communicating electronically with us, you understand and agree to our processing of personal data in this way. If you do not agree to your personal data being processed by social media companies, please contact us at


We may make changes to this policy from time to time. If we change our Privacy Policy we will post the changes on this page, and will hold a record of the changes that we make. When we make significant changes to this policy we will communicate with our supporters to tell them what has changed. Please revisit the policy when you want to confirm how we use your personal information.

This policy was last revised 24 April 2018.

Access to your personal information 

Under the General Data Protection Regulation, you have the right to request and be sent:

  • confirmation that your data is being processed;
  • access to your personal data; and
  • other supplementary information that we hold about you.

You can make a request by emailing us at We will take steps to confirm your identity before releasing any information to you. We will not charge you for providing the information that you request. We will respond to your request within one calendar month of the request, unless there are exceptional circumstances.

Your rights and acceptance of this policy 

By sharing your consent preferences, and using our sites, you consent to the collection and use of information by MHSG in accordance with our Privacy Policy. If you do not agree to this policy, please do not use our sites.

Any personal information submitted via our websites is treated in accordance with current UK data protection legislation (from May 25 2018, we will be working in accordance with the Data Protection Act 2018). To find out more about your entitlements under the current and future data protection legislation, visit the Information Commissioner’s website .

Privacy policy for minors 

The protection of children is very important to us. If you are under 18, please do not provide us with any personal information.

Children should always ask a parent or guardian for permission before sending personal information to anyone online.

Information retention 

We will retain supporters’ data until individuals opt out of receiving our email newsletter.  If an individual opts out their data will be securely deleted from our database.

We will retain data for all current members and for members whose subscriptions have lapsed in the last three years.  We will delete all data for members that have lapsed over three years ago.

If you ask for your personal information to be deleted we will manage your request in a transparent way, and in line with our data retention policy.  We may, however, retain a secure anonymised record for research and analytical purposes.

We regularly review the data we hold to ensure it is held in line with consent of the person who shared it with us.


Whilst we will take all reasonable steps to protect and secure your personal data, we cannot guarantee the confidentiality of any messages transmitted between you and us via email as these are potentially accessible by the public. We will not be liable to you or anyone else for any loss relating to any email message sent by you to us or by us to you.

Like many organisations, we can estimate how many supporters open our emails by counting how many have downloaded the images in them. We also track how many supporters click the links in our emails. By keeping track of which emails our supporters open and click, we can find out what content is popular, and therefore send more of the kind of emails our supporters read. It also means that if a supporter – like yourself – appears to have stopped opening or clicking emails, we can ask them why. This feedback helps us to improve our emails for the future.

Sensitive information 

When using or subscribing to our services, you may choose to provide us with information which is defined as sensitive personal information under the terms of the Data Protection Act 2018. Examples of sensitive information include details of your ethnicity or state of health. As with all the personal information which you provide to us, we shall use and store this information carefully in accordance with this privacy policy. We will always explain why we are collecting this kind of information if we ever ask for it, and we will always ask for your consent to use this data.

This privacy policy is governed by the laws of England, Wales and Northern Ireland.
