tk99 App Privacy Policy: Data protection and cookie control

Why device IDs are captured

tk99 App usually looks at three kinds of device signals

It includes device ID, IP information and session token kept for login, to detect misuse and keep account security intact

What information is viewed

• Device model and operating system
• App version and language setting
• Session time and error log

In Dhaka, many people run one account on multiple phones; in that case, 12 additional verifications may be required to recognize a new device

How tk99 App data protection works

Security is divided into 3 levels

Transmission, storage and access control have separate rules; only limited people can see sensitive information, and activity audit logs are kept up to 90 days

Small but important security aspects

• Data is transmitted via HTTPS
• Alerts are sent for unauthorized login attempts
• Unnecessary data is deleted separately

We have a data security limit; when an old device has weak browser support, some sessions must be refreshed quickly

Cookies and local storage

A total of 4 types of cookies may be used

These track sign-in, preferred language, secure session and usage analytics; when cookies are disabled some features may not remember correctly

What you can control

• You can delete cookies from the browser
• Auto-logout when the session ends
• Local storage data is minimized

This is convenient, but it won't remember all preferences, so on a new phone you may need to reselect a few settings the first time

User rights and options

You have 5 basic rights

Viewing data, correcting errors, limiting some data, objecting and requesting account closure are all possible; the support team usually responds within 24 hours

How to submit a request

• Submit via the help link on the login page
• Provide your account ID on the Contact page
• Follow-ups are done in Dhaka time if needed

Sometimes requests don't proceed without identity verification; it may feel troublesome, but it's needed to prevent data going to the wrong hands

Third-party SDK and sharing

We use 3 external services

These are mainly for analytics, crash reporting and push notifications; before using any service, its data usage policy is reviewed

When sharing happens

• Limited logs are sent to detect errors
• Names are not used in analytics; behavior is observed
• Bangladesh payment indicators like bKash, Nagad, Rocket are only for matching transactions

Not all third-party tools are the same, so unnecessary tracking scripts are not kept here, and that's good

Data retention and deletion

Most logs are kept for 30 to 90 days

Security investigations or legal needs may keep some records longer; after work is done, unnecessary data is gradually deleted

What you can expect

• Visible profile decreases when the account is closed
• Old device tokens are invalidated
• Analytics data is stored separately

There is only one clear limit here: legal documents cannot be deleted immediately, but general usage data is kept as small as possible as quickly as possible
