HOW WE PROTECT YOUR ACCOUNT

Data Handling, Retention and Your Rights

Account Security

Every login triggers an OTP verification step sent to your registered number. Session tokens expire automatically after inactivity, and any new device access generates an alert to your contact details on file.

Data Retention

We keep transaction records — including DANA, OVO, and GoPay payment logs — for as long as required by applicable financial regulations. Account data is deleted or anonymised when you close your account and the retention period has passed.

Cookies and Tracking

We use session cookies to keep you logged in and analytics cookies to understand how pages are used. You can block non-essential cookies through your browser settings; this will not affect your ability to log in or make payments.

Your Data Rights

You have the right to request a copy of the personal data we hold on your account, ask us to correct inaccurate details, or request deletion where no legal retention obligation applies. Submit requests via live chat or email.

Payment records — including deposits and withdrawals via OVO, DANA, and GoPay — are retained for the period required under applicable financial regulations. After that period, records are deleted or anonymised.

Submit a deletion request through live chat or support email after closing your account. We will remove or anonymise your personal data once any legally required retention period has been satisfied.

We use session cookies for login continuity and analytics cookies to measure page performance. You can disable non-essential cookies in your browser settings at any time without affecting your account access or payment functions.
