Tweet Moodifier Privacy Policy

Tweet Moodifier is a web plugin created by researchers at the MIT Media Lab. The purpose of this privacy policy is to highlight which data Tweet Moodifier will collect and how it will be used.


Data Collection and Usage

Tweet Moodifier collects data on users’ usage and engagement with its application. This includes:

At no point does Tweet Moodifier request personally-identifiable information from users (beyond their Twitter handles). Users who authorize Tweet Moodifier to use Twitter authentication for single-sign on purposes may revoke access at any time. All collected data will be retained indefinitely, even after users complete their use of the tool.

All data collected by Tweet Moodifier is used for research purposes. The objective of Tweet Moodifier's research is to better-understand how users perceive and engage with emotional polarization on social media platforms like Twitter. Tweet Moodifier may publish research findings in a wide range of academic and/or mainstream media outlets. All findings will present aggregate results and will preserve the anonymity of individual Tweet Moodifier and Twitter users. If users wish to receive a copy of Tweet Moodifier’s research publications, or withdraw their use data from these findings, they can email tweetmoodifier@media.mit.edu with the relevant request.


Protected Tweets

Some Twitter users (private/protected users) may have decided to make their Tweets only visible to their Twitter followers. Hence, Tweet Moodifier will not read or evaluate emotions of protected Tweets. This extension will check whether the users are public or private before proceeding to read their content.


Data Ownership and Sharing

Tweet Moodifier uses third party vendors and hosting partners to provide the necessary hardware, software, networking, storage, and related technology required to run the web application. Although Tweet Moodifier owns the code, databases, and all rights to the Tweet Moodifier application, you retain all rights to your data.

Beyond these third-party services used to maintain data, Tweet Moodifier will never share user data with anyone outside of the research team.


Changes to Privacy Policy

Tweet Moodifier may change its Privacy Policy from time to time. In such case, Tweet Moodifier will notify users and ask them to accept its Privacy Policy again. This extension will not collect any data without the users’ explicit permission.

Usage Conditions

To have full access to Tweet Moodifier (in case we are running experiments), we will ask you to respond two questionnaires:

If you submit both surveys and use Tweet Moodifier at least sporadically during five days before the second questionnaire comes up, you will automatically be participating for a 30 USD check as a compensation (subject to taxes for non-U.S. citizens resulting in 21 USD). The drawing will be on XX (one month after each experiment starts), and you will be notified by email about the results. To receive the check, we will ask you to fill the MIT Human Subject Payment Form (name, permanent address, and country of citizenship).
