M4siz Limited Privacy and Customer Data Retention Policy

At M4siz, we are committed to protecting your privacy and data security. Users of web sites are concerned about the information that is gathered about your visit to our Web Site and how that information may be used. We invite you to visit our Site without revealing who you are. However, if you choose to give M4siz personal information voluntarily, for example by using our “Enquire Online” page we will only use the personal data you give us in accordance with this Privacy Statement and are committed to safeguarding the personal information collected. GDPR (2016) regulations require that any data retained by M4siz is the result of an affirmative act by the client or potential client. M4siz may be required to share your communication information, related data and content. This will only occur when consent exists, to comply with legal process, or to protect M4siz and our users. When we have your consent or if we believe that disclosure is reasonably necessary to comply with a law, regulation or legal request; to protect the safety, rights, or property of the public, any person, or M4siz; or to detect, prevent, or otherwise address fraud, security or technical issues. If we receive a law enforcement or other third-party request for information we will provide prior notice to the subject of the request where we are legally permitted so to do.

Fair and Lawful Processing

Many of the current regulations and processes M4siz adhere to require a person to be named as the subscriber for the service. An example of this may be a telephone number or broadband service that cannot be anonymous or unnamed or without an address for installation or emergency services purposes. Person(s) wishing to continue with services should, therefore, offer an alternative to allow M4siz to continue being able to continue providing existing services.  M4siz is registered with the Information Commissioner’s Office in the UK and with Ofcom in the UK.
