Keytiles is developed in Europe, where GDPR was born. And we at Keytiles are taking this very seriously!
The website owners to get good quality, statistically relevant information / feedback about the content performance should NOT / do NOT need to know who the visitor is at all!
The Keytiles system
- Does not collect / store / log any sensitive information
About your website visitors or any other information which suitable to identify the visitor as a person himself.
- Never connects visitor activity cross-websites or different devices.
This is not allowed and not possible - guaranteed by system and component design.
- Never shares any information anyhow with 3rd parties
We do not need that as our business model is built around subscription fees and not around gaining extra profit using your tracking data
Keytiles is a paid service. The website owners are paying us and our business model is 100% based on these subscription fees. We do not need any "hidden agenda" (e.g. trying to build profiles out of your visits you make on many websites) to run Keytiles as a business.
When a visitor of a tracked website generates a hit (by visiting a content of the tracked website) Keytiles will know / have access over the following information:
- The IP address of the visitor's machine
which is basically personal data - due to GDPR
- The hit-related information
to see complete list the best idea is to quickly check our Hit Collection API specification
As Keytiles is a HTTP based service due to the nature of the HTTP protocol our system of course has access of this information.
But Keytiles does not store (or even log) the IP address in the exact form as we got it. Because at the very first moment of the hit processing we do apply IP address anonimization method, which means that the last element of the IP address is zeroed out - from this moment tracing back the IP to concrete endpoints => customers => persons is no longer possible even with the ISP data at hand
Take a look into our Hit Collection API specification (the data Keytiles system gets during a hit) - you find all the fields and their documentation there. This is the information Keytiles knows about a hit.
In the above API specification we are marking a few fields with "IMPORTANT NOTE: This is a sensitive field! ..." markers. These are fields where the inbound value is a) free text basically b) Keytiles might store in the database.
Quick list of fields related to some kind of visitor related IDs:
- uniqueWebClientId - check the Cookies section below!
- pseudoUniqueWebClientId - check the Browser fingerprinting section below!
The Hit Collection API is provided for data container (tracked website) owners for integration purposes. This means that basically customers of us can also use it to send in hit data, and these customer-developed codes are out of our hands... Of course we explicitly forbid the "not appropriate data sending" in those marked fields in our Data Tracking - Terms & Conditions document (violation of these principles result in immediate actions from our side) we can not so we do not take responsibility for any consequences caused by the intentional or unintentional misuse of our API endpoint done by customer-developed codes!
As any other analytical tool Keytiles also has a key concept around being able to recognize somehow if a visitor of yours is re-visiting your website - referred as returning visitor - furthermore which pages of yours were visited during one continuous visit-session.
To reach these goals we do store information on the visitor's device, namely the following:
To be able to recognize returning web browsers (your visitor is using) Keytiles is using Cookies at first place.
It is very important to note that we are NOT using 3rd party Cookies!
Unlike many other 3rd party analytics tool provider - all Cookies created by Keytiles service belong to your website domain and not to any of our domains like e.g. keytiles.com! And this means that any of our customers (website owners) - if they wish - can provide mechanisms for visitors to manage these Cookies.
Cookies deployed by Keytiles tracking script are all prefixed with "kt_" prefix so it is easy to find them.
We have more detailed documentation about the cookies, their names and meaning in our TrackingScriptAPI reference article, see:
- and also KeytilesTracking.COOKIE_NAMES
In order to provide some more (non critical but nice to have) features Keytiles tracking script is creating the following entries. Please note that they are all prefixed with "kt_" prefix so it is easy to find them.
This is a map of urlHash => tileId with max 128 entries. This is used to save server resources by being able to send in the referrerTileId (user came from) when visitor visits a content of the website - in case the visitor came from another internal content.
note: this mechanism is enabled only
This mechanism is marked for deprecation!
As soon as we are complete with our current "Milestone 1" changes it will go away completely as data quality will not need this thing anymore. In practice during recent years mechanisms like this is also marked as "grey zone" in GDPR.
Keytiles tracking script might use browser fingerprinting techniques (as best effort) to be able to identify the visitor's device (at least with a good chance) even in the case if devide ID cookies are disabled.
This information is not a sensitive information - as this fingerprint can not be used anyhow to identify a person behind it.
Yes of course! And on the top of that it is very easy!
You have two options for this:
- As a website developer: it is doable with the help of the TrackingScriptAPI provided by the Keytiles tracking script. More specifically you could check KeytilesTrackingApi.deleteAllStoredInformation() method as a starting point.
- As a visitor: Keytiles provides a quick settings page to do that. Check here how any visitor can pull this up!
Short answer: yes.
But Keytiles from this moment is not able to identify returning visitors and join actions into visit sessions. You will just see individual actions but those ones you will see. Still might be valuable!
If you are considering this way probably you should educate yourself a bit in the topic named "micro conversions" - just Google for it!
Keytiles is using Hetzner Cloud and so far we are running in Datacenter located in Germany, Falkenstein
Apart from our technical colleagues nobody else has access to the servers (well, under certain circumstances like hardware failure or similar Hetzner's staff can access the servers physically of course, but this is natural)
We are not sharing the data - not even partially - with any other 3rd parties.
