Walkbase Analytics Privacy Description

This document outlines the privacy concerns related to data collection and processing for Walkbase Analytics.

What is Walkbase Analytics?

Walkbase Analytics is a data processing  and analytics solution supplied by the Finnish company Stratacache Oy (also Walkbase, a Stratacache company). We collect and process data on our customer's behalf to provide them with a better understanding of the visitors in their physical locations. In most cases, for the purpose of data protection law our customer will be the data controller and we are the processor. If you are unsure, you are welcome to contact us and we will help as best we can or direct you to the controller.

What information do we collect?

Walkbase collects location data and footfall. The location data consists of an identifier, timestamp and location.


An anonymised identifier derived from the MAC address of the wireless device.


The time and date when the wireless device was observed.


A location context of when the wireless device when it was active. For example "Store A" or "Section B in Store A".


A simple count of how many people have entered the site, as measured by sensors at the sites entrances.

What information do we process?

To collect the above described data, we process and aggregate the following data without storing it.

MAC address

We generate an anonymised identifier from the MAC address of wireless devices, collected from either a WiFi or Bluetooth device. The original MAC address is discarded after the anonymised identifier is generated and only the anonymised identifier is stored. The anonymisation process a one way process and converts the identifier from a unique one to a non-unique one which cannot be reversed to the original MAC.

How do we protect the data?

We have designed our systems to keep as little information as possible and we always store it on encrypted storage with limited access. All communication is done using encrypted channels. We use our private hardware and all access and activity on them is logged and audited.

How will we use the data?

We use the data to provide aggregated reports of the movement and behaviour of the wireless devices. These reports are in the form of 15 devices was seen in Location A between time X and Y, 7 of these has been seen at least once during the last month. We will not try to identify individual devices or persons, nor provide the ability to do so to any of our customers. We do not provide details about individual for less than 5 devices at any time.

How long do we store data?

The duration depends on what type of information it concerns. We don't store data longer than necessary and irreversibly delete it when we have produced the aggregated statistics. We only store the aggregated statistics while we have a business relation with the owner of the data.

MAC address

The original MAC address is only kept a very short while, generally less than 60 seconds, before being anonymised. An exception to this is that in the case of an opt-out, then the opt-out is stored indefinitely. In this case we do not store any location information about the opted-out MAC address only the timestamp of when it was opted out.

Anonymised location data

The anonymised data is stored at most for as long as we have an active contract with the customer. In some cases, depending on the agreement with the customer it might be stored for a shorter time, refer to the data policy of the customer for which we process data.

How can I remove data collected about me?

It is not possible to retroactively remove aggregated data for any device (individual) as we don’t store a link between the original and the anonymised identifier. You can opt-out from any further processing by going to which will prevent any further collection of data from the opted-out device.

Is the data sold or transferred to a third party?

No. While we regularly share aggregated data with our customers we do not share any of the data described above unless legally required.

Can I get a copy of my data?

It is not possible to request a copy of your data. We do not store any identifying data and have no way of figuring out what data belongs to you.
