Altius Teacher Corner — Privacy Policy

Last updated: 9 September 2026

This Privacy Policy describes how information is collected, used and protected when you use the Altius Teacher Corner mobile application (Android package com.ispf.altius.teachercorner) and its related services, delivered as part of the Altius CSF Tarang programme.

The application is operated on the programme's behalf by Tactile Education Services Private Limited ("ThinkTac"), which provides and maintains the Teacher Corner platform. The programme itself is run by the Innovation and Science Promotion Foundation ("ISPF") together with its programme partners, Altius Foundation and Central Square Foundation (CSF). In this policy, "we", "us" and "our" refer to ThinkTac and ISPF acting together in those roles.

1. Who this application is for

Altius Teacher Corner is intended for use by teachers, trainers and programme administrators, who are adults. It is not designed for, marketed to, or intended to be used by children. Accounts are issued by the programme; the application is not open to general public sign-up.

Mobile phone number To sign you in using a one-time password (OTP) and to verify your identity.
Teacher ID Issued by the programme, used together with your phone number to authenticate you.
Name and profile details Provided during registration or account setup, so the application can identify you within your programme.

Programme activity data Records of activities you conduct, classroom and learner progress, ratings and reflections you enter, and the classes, grades and subjects you teach. This is used to run the programme and to report on its delivery.
Photos you choose to upload Where you submit a photograph as evidence of a completed activity, the image is uploaded and stored with that activity record. The application accesses your camera or photo library only when you choose to attach an image.

We do not collect your advertising ID, and the application contains no advertising and no third-party advertising or tracking SDKs. We do not collect your precise location, contacts, call logs, messages, calendar, health data or financial information.

3. Learner information entered by teachers

As part of programme delivery, teachers record classroom and learner progress in the application. Where that information relates to a child, it is entered by the teacher in their professional capacity and is used only for programme delivery and reporting. We do not knowingly collect personal information directly from children, and children do not hold accounts on this application. Teachers are asked to record only the minimum information the programme requires, and to follow their school's own policies on learner data.
