Privacy Policy

This policy explains how the Human-X Interactions Lab and its student researchers collect, use and protect the data you provide when you visit and use Imprint. For what taking part involves, see the Informed Consent Form.

What Imprint collects

  • Your account: your username, your email address, and the password you set, which is stored only as a secure hash. If you sign in with Google, Google shares your email address, your name and a link to your profile picture, and Imprint keeps them with your account.
  • Your profile: the cities you often walk in, your age group, your gender, whether you have a mobility impairment or disability, any temporary condition that affects how you walk, your highest level of education, your occupation, how familiar you are with accessibility issues, whether you have done image or data annotation before, and how often you commute and walk.
  • Your contributions: the boxes, categories and answers you give for each photo, and your answers to the workload questionnaire and the exit questionnaire.
  • How you use the annotation screen: the actions you take, the time each step takes, and the type of device, browser and screen size you use.
  • That you agreed to the Informed Consent Form and confirmed you are 18 or older, and when.

Why Imprint collects it

  • To study how people judge what blocks a sidewalk, and to improve a model that learns from those judgments.
  • To understand the background of the people who take part, and how it relates to the answers they give.
  • To run the platform: to sign you in, keep your place in a session, and send a password reset link when you ask for one.

How it is protected

  • You are identified only by a pseudonymous identifier. No personally identifying information is attached to your annotations or activity logs.
  • Your profile answers are stored separately from your annotations and activity, and are linked to them only through that identifier.
  • All data is stored on university-managed infrastructure.
  • Results are reported in aggregate in a thesis and any resulting publications. No individual contributor will be identifiable in any output.
  • Your personal information is never leased, sold or given to any third party. It is used only for this research.
  • The annotations you produce may form part of a research dataset used in future accessibility research, in de-identified form.

How long it is kept

Your data is kept only for the duration of the study and the analysis that follows it.

Your choices

  • You can stop taking part at any time, without telling anyone and without any penalty.
  • You can ask for your data to be deleted at any time. It will be removed unless it has already been irreversibly aggregated for analysis.

To ask for deletion, or with any question about your data, email francis_bawa@dlsu.edu.ph.

Cookies and browser storage

  • A sign-in cookie keeps you signed in for a day, or for 30 days if you choose Remember me or sign in with Google.
  • Your browser keeps your place in a session, so you can pick up where you stopped, and the time you last saw the landing page's opening animation, so it is not shown again for a day.
  • Imprint uses no advertising or analytics cookies.

Other services

  • If you sign in with Google, Google handles that sign-in under its own privacy policy.
  • The map on the landing page loads its images from CARTO, which receives your browser's request for them like any website would.
