Privacy Policy & GDPR

Privacy Policy

Our policy on privacy is simple and clear; identities of users are none of our business. We never track or store any data that can be used to identify a particular person: no name, address or phone number, no email address, user name or IP address is recorded by our service. Instead we keep our users totally anonymous. Only a random number stored in a cookie tells us that the browser who visited a page was the same browser as the one who visited another page yesterday. The data can be collected for the purpose of advertising and can be shared with third parties.

Leiki is a member of EDAA, a European cross-industry initiative to enhance transparency and user control for online behavioural advertising (OBA). We are also integrated with Your Online Choices, a benchmark for companies committed to responsible advertising practices.

A typical profile consists of 50-200 weighted categories and looks like this (click on the image to view in full size):


Leiki is compliant with European General Data Protection Regulation. Key legal definitions in GDPR are Personal Data, which means data that can be identified to a natural person, and Data Processor, which is a company that processes Personal Data. By default Leiki’s data is completely anonymous and does not contain any identifiers of a natural person, and thus it is not Personal Data. Normally Leiki does not act as a Data Processor.

Some of Leiki’s customers can have registries of Personal Data, for example publishers have subscriber databases. It is possible to set up a co-operation where Leiki’s anonymous data is sent to the customer, and the customer connects it with their Personal Data. Even though Leiki itself still does not have any personal identifiers, in such a case Leiki’s data becomes Personal Data and Leiki becomes a Data Processor. As the actual person registry is on the customer side, Leiki only works with them if the customer is fully compliant with GDPR regulations.

Publishers’ sites

Some of our publishers use registration and login of users, and may have asked you for personal information. For example, webshops like Amazon and eBay usually require registration and login before you can make a purchase. If you have given them the right to do so (by accepting terms of use), they can combine their person registry with our service. This may allow them to provide you with better special offers by do things like combining what they know about your purchase history at their store with the interest profile. Our privacy policy remains the same in these cases: Leiki has no idea who you are. If there’s any personal information it’s all in the customer’s system, not ours.
