To view our Privacy Policy for our corporate website please visit http://linkett.com/ext/new/privacy.html.

Your use of our services to which this policy is linked (the “Service”) indicates to us that you have read and accepted our Privacy Policy and User Agreement.


AdStash focuses on understanding how large groups of people behave only when around digital signs. The Service collects and aggregates information that is broadcast by Wi-Fi enabled devices. We use this data to create reports for our partners to enable them improve their content performance and understand how much to bill them. The Service allows entities such as DOOH Networks to engage directly with their visitors through Wi-Fi and digital signage applications. Adstash helps us and our partners provide you with customized content experiences.

We have developed this Privacy Policy to advise you about the information we may collect about you and our possible uses of this information, and to inform you about how to modify your service preferences.

AdStash Information Practices: Information Collection

When you walk near or enter one of our partners’ locations with a Wi-Fi enabled mobile device, our Wi-Fi access points may detect the presence of that device and its Media Access Control Address (“MAC Address”). We refer to this information as “Visit Information”. The Visit Information is collected and processed as you move across partners that use our technology. We and/or our partners may aggregate the Visit Information into reports for us and/or our partners. If you object to us and/or our partners’ use of the Visit Information, please see http://linkett.com/ext/new/privacy.html to “opt-out”.

Information Use

The Visit Information is used to provide aggregated reports for our partners and for research to help us improve our products and develop new services. Our partners use the reports for a variety of purposes, such as:

  • Measure traffic near a digital sign;
  • Measure the effects of advertising;
  • Generate relevant digital signage content;

Generally Applicable Information Practices Information Use

The Visit Information is used by or shared with our partners as described above, so that we and/or they can provide you with a better experience.

In the event that AdStash is acquired by or merged with a third-party entity or is potentially on the verge of being acquired by or merged with a third party entity, or its substantial assets are acquired by a third party, or in any partial or total sale of its assets including in the event of bankruptcy, or in any other corporate change, AdStash may transfer or assign the Visit Information as part of that actual or potential merger, acquisition, sale, or other change of control. The terms of this Privacy Policy will apply to your data as transferred to the new entity.

We may share information in response to a request for information if we believe disclosure is in accordance with, or required by, any applicable law, regulation, legal process, or governmental request. We require a warrant or court order before disclosing any of the limited amount of device location data that we possess.

Your Choices

AdStash complies with the Mobile Location Analytics Code of Conduct. As provided for in the code, you may elect to opt out of associating a device with a MAC address anytime at: https://smart-places.org/https://smart-places.org/. We will remove any existing MAC address data in the future.

If you are a California resident, California Civil Code Section 1798.83 permits you to opt out of AdStash sharing personal information with third parties for their direct marketing purposes here http://linkett.com/ext/new/privacy.html.

Data Retention

Data from the Visit Information is retained for 24 months, unless it is necessary to keep the information for legal purposes. After 24 months, data about hashed MAC addresses is retained in aggregate form.

Data Security

To guard against unauthorized access, we have in place commercially reasonable technical and other controls to help protect the information. Please note that no method of transmission over electronic systems or of electronic storage is 100% secure and, therefore, AdStash cannot guarantee security.


We may update this Privacy Policy from time to time. We will post these changes in this policy, and suggest that you revisit this policy periodically to stay informed of any updates.
