  • With Third Party Service Providers we may use specific contracts approved for use in the UK which give Personal Information the same protection it has in the UK.

How we keep your Personal Data safe

Sumdog maintains a reasonable and appropriate security programme designed to prevent your Personal Information from being accidentally lost, used or accessed in an unauthorised way, altered or disclosed.

Our security measures include data encryption in transit and at rest, firewalls, multi factor authentication for systems, malware protection, regular staff training and physical access controls. Sumdog also holds the Cyber Essentials certification.

On your web browser, you’ll see a padlock beside the Yenka web address ( ). Clicking the padlock gives you the details of our security certification.

In addition, we limit access to your Personal Data to those employees, agents, contractors and other Third Parties who have a business need to know. They will only process your Personal Data on our instructions and they are subject to a duty of confidentiality.

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

Our security policies are reviewed on an annual basis to ensure they are kept up to date. Changes are approved by senior management.

Automated decision making is not used in our Yenka website.

Children’s data

We do not process children’s data on the Yenka website. This website is not intended for children.

If we’re informed that we have collected Personal Data from anyone under 18 without permission, we will delete that data as quickly as possible. If you believe that this has happened, please contact us at

Your rights

It is important that the Personal Information we hold about you is accurate and current. Please keep us informed if your Personal Information changes during your relationship with us.

Where the UK GDPR or the EU GDPR applies, by law you have the right to:

  • Request access to your Personal Data. This enables you to receive a copy of the Personal Data we hold about you and to check that we are lawfully processing it.

  • Request correction of the Personal Data that we hold about you. This enables you to have any incomplete or inaccurate information we hold about you corrected, though we may need to verify the accuracy of the new data you provide to us.

  • Request erasure of your Personal Data. This enables you to ask us to delete or remove Personal Data where there is no good reason for us continuing to process it. You also have the right to ask us to delete or remove your Personal Data where you have successfully exercised your right to object to processing (see below), where we have processed your information unlawfully or where we are required to erase your Personal Information to comply with law. Note, however, that we may not always be able to comply with your request for erasure for specific legal reasons which will be notified to you, if applicable, at the time of your request.

  • Object to processing of your Personal Data where we are relying on a legitimate interest (or those of a Third Party) and there is something about your particular situation which makes you want to object to processing on this ground. You also have the right to object where we are processing your Personal Data for direct marketing purposes. In some cases, we may demonstrate that we have compelling legitimate grounds to process your information which override your rights and freedoms.

  • Request the restriction of your Personal Data. This enables you to ask us to suspend the processing of Personal Data about you, (i) if you want us to establish its accuracy or (ii) where our use of the data is unlawful but you do not want us to erase it, (iii) where you need us to hold the data even if we no longer require it as you need to establish, exercise or defend legal claims or (iv) you have objected to our use of your data but we need to verify whether we have overriding legitimate grounds to use it.

  • Request the transfer of your Personal Data to you or another party. 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.

  • In the limited circumstances where you may have provided your consent to the collection, processing and transfer of your Personal Data for a specific purpose (such as electronic marketing or photographs), you have the right to withdraw your consent for that specific processing at any time. We will then no longer process your information for the purpose(s) you originally agreed to, unless we have another legitimate basis for doing so.

If you want to exercise any of these rights, please contact the Sumdog Data Protection Officer in writing. We will try to act on your request within one month. Occasionally it could take us longer than month if your request is particular complex or you have made a number of requests. In this case, we will notify you and keep you updated.

We may need to request specific information from you to help us confirm your identity and ensure your right to access the information (or to exercise any of your other rights). This is another appropriate security measure to ensure that Personal Information is not disclosed unlawfully.

We will only require a fee if your request is clearly unfounded, repetitive or excessive. Sumdog Ltd reserves the right to refuse to comply with your request in these circumstances.

If the use of your Personal Data is subject to the UK GDPR, you have the right to lodge a complaint about how we handle your personal information with the Information Commissioner’s Office / the ICO. You can call the ICO’s helpline on +44 (0)303 123 1113.

Updating this Privacy Notice

We may change this Privacy Policy from time to time. We may try to notify you about the processing of your Personal Data if there are substantial changes.
