tk111 App Privacy Policy

How privacy works in the tk111 App

The main point of this policy is simple: only necessary information is viewed via anonymous analysis to understand usage, and personal data is kept separate

Dhaka-based logins also follow the same rules; records related to bKash, Nagad, or Rocket are used only for transaction verification, not to create a profile

• Anonymous data is kept separate
• You can control cookie preferences
• Personal data is viewed only in a limited way
• Response to security requests within 1 business day

Anonymization method

Step 1: Name, phone number and account ID are separated, then that information is aggregated to view only general trends

This yields data for research, but individuals cannot be identified; cookies, device type, and session duration are segmented into 3 levels

Step 1: Remove direct identifiers

Phone, email, and payment IDs go to separate tables; these are not in the general reports

Step 2: Data viewed together

It tracks how many times you've logged in, which pages took longer, etc.; this method has been used since 2019

Scope of research

In research, only usage patterns, device behavior, and cookie signals are observed; which of 237+ titles is searched more can be understood

No personal messages, bank information, or sensitive logs are viewed here; among 5.2M+ active users in Bangladesh, there is no way to reveal a separate identity

Rules for sharing with teachers

Only a summary may be shared with universities or research teams, this is verified in advance and then a limited portion is provided

To compare Dhaka and Chattogram usage patterns, no name or number is needed; the overall trend is sufficient, and that is sent

1. The request is written, then evaluated as needed
2. Data is de-identified
3. Only summaries are shared
4. Finally, another review is conducted

What never happens

Personal accounts, bKash IDs, Nagad numbers, or Rocket information are not shared, and none of this is included in any research notes
