Information users give us

Student Users

We do not ask Student Users to enter any information that, in itself, is considered personal information.

Sumdog's writing games are the only place where students are asked to input text as an answer. Their access to these games is controlled by the Parent and Teacher users linked to their account.

When they play these writing games, we remind them not to enter any personal information. Sumdog does its best to enforce this rule automatically. To help provide the safest possible environment, we permit teachers and parents to view what each child has written.

Parent Users

We collect the following personal information from Parent Users.

On sign-up, Parents Users enter their:

  • first & last name
  • email address & password

Parent Users then enter information about each of their children:

  • first and last name
  • date of birth
  • school login details

Parent Users may also send an email invite to other parents by entering their names & email addresses. 

If Parent Users choose to subscribe to premium services, they enter:

  • postal address
  • payment method details

Teacher Users

The following personal information is collected from Teacher Users.

On sign-up, Teacher Users enter their:

  • first & last name
  • email address & password
  • school name and address

Teacher Users may then enter information about their students:

  • first and last name
  • grade level or school year
  • class

In the future, we may ask teachers to enter the date of birth of students. If we do this, it will always be optional.

Teacher Users may also invite other teachers, by entering their names and email addresses.

All Users

All users can choose the gender and visual appearance of their on-screen avatar. They can also specify profile details, such as their favorite Sumdog game.

In order to provide the best possible service, we reserve the right to extend the types of information we ask users to give us.

You can choose not to give us your information. However, this will prevent you from using most parts of Sumdog.

Information we collect automatically from users

When you use Sumdog, we may collect the following information automatically:

  • educational data from your activity on Sumdog, for example accuracy and speed of answers to Sumdog's questions;
  • text written in Sumdog's writing games;
  • data on your use of Sumdog, for example the last time you logged in;
  • communications you have made with other Sumdog users;
  • technical information, for example the device you use, your operating system and your IP address.

The data we collect automatically may be linked to your account and to the personal information that you have given us.

Some of the information that we collect from Student Users may be accessed by the Parent Users in their Sumdog Family, or the Teacher Users linked to their Sumdog School.

We also use analytics software to help us understand how Sumdog is used. Information recorded by this software is anonymized, and cannot be related to individuals. To help us optimise our email communication, we may use customised links, or small images called web beacons. These allow us to understand how our messages are received by our users.

In order to provide the best possible service, we reserve the right to extend the types of information we automatically collect from users.

Sumdog uses Cookies

We use small files called Cookies to help make Sumdog easier to use, and to help us improve the site for you. We store these Cookies on your computer.

Cookies can't be used to identify you personally. They simply let us know when you return to the site. This helps us, for example, to remember that you're logged in, or to remember the settings you chose on your previous visit. We store them in the Cookies folder on your computer.

Here's a table describing the Cookies we use:

How we store and process your information 

Your information is stored and processed on our servers. The only exception to this is payment card details: for security reasons, these are stored by our payment service provider.

While your information is being transferred to our servers, it is encrypted using SSL. This helps to protect it in transit.

Information we collect on student users will only be stored and processed in the United States of America or the European Union. Depending on your location, we may need to transfer it to these places. Transfers of this information from the European Union to the USA will be done under the terms of the Model Contract Clauses approved by the European Commission.

We also collect information from teacher and parent users that doesn't relate to individual students - for example, in our online accounting systems. We may transfer this information to other countries. If you are from the European Union, and we need to transfer this information to countries outside the EU, we will undertake due diligence to ensure that the transfer complies with the UK Data Protection Act.

Suppliers of support services to Sumdog - for example, the provider of our data storage - may process any of the information we collect on our behalf.

We will take all steps reasonably necessary to ensure that this information is treated securely.

How we use your information

Your information is used during the normal functioning of the Sumdog service. This may include:

  • informing you about our services, or to help you to use them, such as telling you about a new Sumdog game, or notifying you of the end of a trial period;
  • identify and where necessary act against improper or illegal use of Sumdog. This helps keep Sumdog safe for all of our users;
  • analyze usage patterns or request feedback from you about our services so that we may improve the service

Your information is held by Sumdog Ltd. It may also be accessed by our wholly-owned US subsidiary, Sumdog Inc, in accordance with the terms of this Privacy Policy.

If we need to use your personal information for any other purposes, other than the normal functioning of the Sumdog service we will seek your permission prior to doing so.

We will not use your personal information to develop a personal profile of you.

If you have given us your email address, we may send you messages via email. This may include information about new features or services, or about your usage of the site, or the usage of others in your Sumdog School or Sumdog Family. To choose which types of email you receive from us, please go to Please note that there are certain emails that you can't opt out of receiving, unless you delete your account entirely, as these are concerned with the administration of your account.

We will not use students' personal information for targeted advertising.
