HELP CHANNELS

Switch to Privacy Support

Privacy requests move faster when you send them from your registered email or the help form after login.

Live chat Use live chat for quick questions about what we store, how cookies work, or why a login was flagged. We answer in English for Indonesian customers, and the chat log stays attached to your account request.

Email Send a message from your registered address if you want a copy, correction, or removal request handled in writing. We check the sender against the account before we change any record, which keeps the request traceable.

Help form Open the help form after login when you want to update profile details or ask how long a record stays in our system. The form captures the account ID, device, and time stamp for verification.

SECURITY CONTROLS

Browse Security and Cookie Controls

We keep privacy controls close to your account tools, so you can ask what we store, correct details, or request a copy without a long back-and-forth.

Data use

We collect account name, contact details, login time, device type, and transaction references only when they are needed for access, support, or payment matching. We do not ask for extra fields that are not used in the account flow.

Cookies

Cookies keep your session active, remember language choice, and help the page load the last area you opened. You can clear them in Chrome, Safari, or your mobile browser settings if you want a fresh session.

Security logs

Failed logins, IP changes, and device swaps are logged so we can spot account abuse and help you recover access faster. Those logs are reviewed only by staff who handle security and account support.

Retention

We keep records for as long as the account is active and for any period needed to settle disputes, security checks, or legal requests. After that, data is removed or anonymised according to our process.

Your requests

To request a copy or correction, send the message from your registered email or submit the form after login. We verify the request against your account details before making any change.

Contact path

If you have a privacy question, use live chat between 09:00-21:00 WIB or email us through the support address shown in your account area. We answer in the same channel whenever possible.

Open Common Privacy Questions

These questions focus on data use, cookies, and how to reach us for changes. If you want a copy, correction, or deletion request, start from the help form after login or email from your registered address. The same policy applies on desktop and mobile, and access remains subject to local law where service is allowed. We keep responses tied to your account record so you can follow progress in one place.

We collect the details needed to create and protect the account: name, contact channel, login time, device type, and transaction references. If you do not submit a field, we do not create a separate record for it.

We keep only the reference data needed to match the transaction and answer a support request. Full wallet credentials are not stored in the privacy record, and any extra detail stays inside the payment provider flow.

We keep active-account records while they are needed for access, security, and support, then retain only the parts required for dispute handling or legal duties. After that, we remove or anonymise them.

Yes. Send the request from your registered email or the help form after login, and we verify it against your account before making changes to phone number, email, or profile name.

Our cookies remember your session, language choice, and basic device settings so the page works the same on Chrome, Safari, and mobile browsers. They do not read your private messages or device files.

Use live chat from 09:00-21:00 WIB, email the support address in your account area, or send the form after login. We route the case to the team that handles data requests.
