How is account data stored?
Your name, phone number and account settings are stored in the ck4 App to speed up sign-ins; the information you provide in ck4 Login and ck4 Register is used only for active services and security purposes.
Many users in Dhaka log in from multiple devices, so sessions, language preferences and device IDs may be stored temporarily to reduce re-authentication hassle.
What happens when no longer
When an account is closed, many records are not visible immediately, but for security, legal obligations and support trace keeping, some data are kept for a specified period.
Why is transaction data kept?
Deposit, records and verification combined keep transaction data; for Bangladesh users, the references they provide to bKash, Nagad and Rocket should match.
This helps detect wrong entries; if any issue, the team can quickly locate a specific transaction, hence resolution is faster.
How long is kept?
Typically, certain records may be kept for several years; this is needed for security, chargeback-type disputes and internal audits.
How are usage data and cookies used?
Cookies keep your login, preferences and site speed smooth in the ck4 App; these are small data files, so you don't have to set the same settings repeatedly.
Some data are used for analysis to see which page takes longer and where users pause, making the site clearer.
What can you control?
Most browsers allow cookies to be disabled or deleted, but that may cause login to not be remembered or some preferences not to work properly.
What remains after account closure?
Even when the account is closed, not all records are deleted at once; for security, legal obligations and support trace keeping, some data are kept for a specified period.
If you wish, you can view a list of limited data: basic records used in ck4 Login, transaction summaries and cookie identifiers are shown under a separate policy.
Deletion and Limited Retention
What isn't needed can be deleted, and what must be kept for legal or security reasons remains with restricted access.
What rights do you have?
You can view your data, correct it and request deletion; if there is incorrect information, notify support and verification will begin.
You can also see how data is used, especially when changing devices or registering a new ck4, so the old settings can be matched again.
What to do
Write to support, and clearly state your account-related request; usually you get an initial response within 1 to 3 business days.
Open ck4 App for HelpContact and brief rights summary
If you have any questions, write on the contact page; Bangladesh users' support is arranged according to Dhaka time, so sending messages is easier.
In short, data is stored in the ck4 App for security, service and verification; you have rights to view, correct and request deletion within valid limits.
