Chrome will ask you for the following permissions when you install HabitLab. Here’s how we use them:

  • “Read and Write Data on All Websites”: We need this permission to change the appearance of pages and deploy interventions on the sites you choose to reduce your time spent on.
  • “Show Notifications”: We use notifications to show you a daily summary of how much progress you have made towards achieving your goals.
  • “Browsing History”: We use your browsing history to determine how much time you’ve spent on sites in the past, so we can measure how much time you’ve been saving.


You can opt-out of logging, in which case no data will be sent to our servers. If you do enable logging, then the following data will be logged. Data is anonymized and will not be shared with anyone outside our research team.

  • Enabled goals and interventions
  • For each visit to a goal site: which intervention was deployed, and how long you spent

HabitLab is a research project run by the Stanford HCI Group.

Description: HabitLab is a research study on developing better online habits. You can participate by installing and using the HabitLab Chrome extension. The extension will ask you to specify some goals (such as spending less time on Facebook), and will deploy various interventions that aim to help you achieve those goals. It will log data related to progress on your goals (such as time spent on domains), which will be used by our algorithms to determine which interventions work for you. Data will not be shared with anyone outside our research team. You can opt-out of sending this data to our servers on this page, or via an option under the extension settings.

Time Involvement: You can participate for as long as you want by keeping the extension installed.

Risks and Benefits: There are no forseeable risks associated with using HabitLab. We cannot and do not guarantee or promise that you will receive any benefits from using HabitLab.
