Insightful Living Through iLog

Introducing iLog, your personal guide to understanding and enhancing your daily habits through data.


iLog is an application developed by the KnowDive group at the Department of Information Engineering and Computer Science of the University of Trento. We developed it to collect data for research purposes. With the user consent, it is able to collect data from the smartphone internal sensors and send context sensitive questions. The final goal is to study the users’ habits, allowing to react accordingly with personalized services, and generating research datasets for further studies.

User Consent and Privacy Protection

The correct management of the information collected and the participants’ privacy is of utmost importance during the use of the iLog app. For this reason, we have established the mandatory steps before any data collection with the iLog app can take place:

  1. Ethical Board clearance: an ethical board or similar entity, local to the institution where the survey is going to take place, has to approve the survey’s protocol. Recommendations and limitations are implemented according to their feedback. 
  2. Institutional legal agreements signed: institutional authorities from the institutions involved in the survey agree and sign on the documents regulating how the data from the survey will be collected, stored, anonymized and used. This also includes compliance with local privacy laws, like GDPR.
  3. Acceptance of the Informed Consent / Terms of service before each user’ participation: iLog is configured so that just downloading and opening the app will not trigger the collection of any data from the participants’ phone. Instead, users need to input an experiment code provided by the researchers and subsequently accept the displayed Informed Consent / Terms of Use information before data collection may begin.


iLog is currently available through the Android store Google Play, and a beta version for iOS is available on the Apple AppStore
