Effective date and ok37 App data policy
Effective date: August 2026 This policy explains what information is collected, where it is stored, and how you can control it
Biometric login, cookies, and device-based verification are used in the ok37 App; we explain this so you can decide in advance
Three points for quick reading
- Fingerprints stay on the device.
- Session cookies simplify login
- You can disable anytime
Biometric data used in the ok37 App
Device-based facial recognition
Some phones have facial recognition, also only for login, not creating extra profiles
Local permission control
Biometric permission can be enabled or disabled; Nagad users in Dhaka can manage this easily
Biometric data is sensitive, so we do not merge it with account information; your phone remains the first layer
Ok37 App: store data on device
Biometric tokens stay on device's secure enclave or equivalent; fingerprint uploads to server are not performed
This also keeps login fast even on busy Dhaka networks; local verification works with low internet
Three rules to remember
- Do not send fingerprint copies
- Re-verify when you change devices
- Do not enable biometrics on public phones
What goes to the server and what doesn't
What goes
During login, session ID, and limited error data are sent to indicate account status
What doesn't go
Raw biometric samples, scanned images, or unnecessary personal notes are not uploaded
Why this is needed
Same security rules apply when logging in with Roket or bKash; payment stays on separate channel
Your registered phone number and session data are used only for verification; keeping more would cause trouble, so we keep less
How cookies work
Cookies remember site language, session, and preferences, so settings don't need changing repeatedly
Many Bangladesh users access on mobile data, so small cookies are used to help pages load faster across the network
What happens if cookies are
- Language preferences may need to be set repeatedly
- Login session may end quickly
- Some personal settings may not be remembered
How to disable cookies
Go to browser settings to change cookie permissions; keep only necessary cookies, disable the rest
You can still log in to a registered ok37 account, but you may have to verify again
Two quick steps
- Open the browser privacy menu
- Adjust cookie permissions as needed
Your rights and data protection
You may request data copies or corrections if information is wrong
If needed you can delete or limit your account; these controls uphold user rights
Can be done easily
- You can view data
- You can revise old data
- You can disable biometric permissions
Legal basis for ok37 App
We use data based on security, account verification, and service needs as the main legal basis
A Dhaka-based support channel is also available for users in Bangladesh, providing quick answers to questions
