Prerequisites for Service use and data used in the Service

Potential login options include email and confirmation code, or social media identity solutions (e.g. Google account). Kesko may add new or remove previously used login options at its discretion for reasons related to e.g. data security or similar.

If the User uses their email address to create a K-Tunnus, the User must separately confirm the email address given within a timeframe specified in the Service. If the User does not confirm the email address within the timeframe given, the information is removed from the system. If the User has not confirmed the email address they have given, but still wants to create a K-Tunnus, the User must repeat the registration process.

For new Plussa members, K-Tunnus ID linked with their Plussa-membership will be created upon joining. The User may also link their K-Plussa membership to their K-Tunnus at a later date. Linking Plussa membership and K-Tunnus enables a personalised service experience for the User based on registered K-Plussa purchase data and other profiling information. When the User’s K-Plussa membership is linked to the K-Tunnus, the User can access features utilising the User’s purchase history or other profiling data. Such features may include:

  • A view of the User’s Plussa points and personal Plussa offers
  • A view of the User’s purchase history
  • A possibility to update or independently change information related to the User’s K-Plussa membership

Linking a User’s K-Plussa membership to their K-Tunnus requires strong identification to verify the User’s identity. The strong identification may be carried out using online banking codes, a mobile certificate, or other generally approved method of strong identification employed by Kesko. The Service will provide the User with a link to the identification service and its Data Protection Notice. If the User is unable to carry out electronic identification or if the strong identification service cannot be used to identify a K-Plussa member, customer service may carry out manual identification.

The Service uses cookies to produce services, enable targeted content, and measure the effectiveness of advertising. If the User links their K-Plussa membership to their K-Tunnus ID, data related to the K-Plussa membership may be used to analyse the functioning of the services employed by the User (e.g. or the K-Ruoka mobile app), and to further develop them.
