Who we are
Zero Dementia is built by Biotech Wallah Pvt. Ltd., Lucknow, India. Contact: info@biotechwallah.com.
This website
The website does not run the assessment. If you contact us or join a waitlist, we keep your name, organisation and email to reply to you, and nothing else.
The assessment app
In the app, answers and notes are stored encrypted on the tablet. Voice or eye recordings are made only with their own consent form. Research use needs separate consent and ethics approval.
Your rights
Under the Digital Personal Data Protection Act, 2023 you can ask to see, correct or erase your information, and withdraw consent as easily as you gave it.
Changes
We will update this page when our practices change. This page is a working draft pending legal review.
