We do not charge fees on deposits or withdrawals. The full amount you deposit is credited to your grend303 account immediately after our system confirms receipt. Similarly, when you request a withdrawal, we process the full amount without deducting platform fees. However, your bank or payment provider (DANA, e-wallet, mobile banking, local payment, online payment, e-wallet, mobile banking, local payment, online payment, e-wallet) may charge fees for their own processing or cross-bank transfers. Those fees are set by your payment provider and are not controlled by grend303. Check your payment provider's fee schedule before depositing or withdrawing if you want to understand all costs involved.

We protect your personal information using industry-standard encryption, secure data centres, access controls, and audit logging. During account creation and Know Your Customer (KYC) verification, you provide your full name, date of birth, national ID number, and address. We encrypt this data at rest and in transit and restrict access to authorized grend303 staff only. We retain KYC data for at least five years after account closure to comply with anti-money-laundering regulations. We do not sell your personal data to third parties for marketing. We may share data with payment processors, fraud-prevention services, and government authorities only when required by law. For full details, see our privacy policy

Payments and transactions

Yes. We accept deposits via mobile banking, local payment, online payment, and e-wallet through bank transfer and Virtual Account (VA) routing. When you select a bank transfer during deposit, our system generates a unique Virtual Account number tied to your grend303 account. You transfer funds from your own bank account to this VA; the system confirms the deposit within a few minutes of settlement. We also accept wallet-based methods (mobile banking, local payment, online payment, e-wallet, mobile banking, local payment), which often settle faster. Bank transfers typically clear within one to two hours during business hours, though times may vary depending on your bank and whether the transfer occurs during a public holiday (for example, Idul Fitri or Imlek). Withdrawals are also sent back to your registered bank account after compliance review.

You can reach our support team via in-app chat (fastest response), email to our support inbox, or the contact form on our help centre. Email responses typically arrive within 4–8 business hours during weekday business hours (Monday to Friday, 08:00–18:00 Jakarta time). For urgent issues (account lockout, suspicious activity, withdrawal problems), use in-app Priority Support for faster escalation; priority requests receive a response within 2–4 hours. Weekend and holiday support is available via in-app chat but may have longer response times. Include your username, a description of your issue, and any relevant transaction or account details when you contact us so we can help you faster.

Games and betting

RTP stands for Return To Player and is a theoretical percentage showing how much a slot game returns to players over a very large number of spins. For example, a slot with will theoretically return our welcome offer for every our welcome offer wagered over millions of plays. RTP is calculated by the game developer and is independent of grend303. Each of our slot games (Aviator, Sweet Bonanza, Gates of Olympus, Fortune Tiger, Mahjong Ways) displays its RTP in the game info or settings menu. RTP does not predict individual session results or guarantee any specific payout on a single spin. Results on every spin are random and determined by certified random-number generators. Over short play sessions, actual results can vary widely from the RTP due to normal variance.

Our loyalty programme rewards active grend303 users with points earned from deposits, wagering, and tournament participation. Points accumulate in your account as you engage with our sportsbook (Liga 1, Piala AFF, Champions League), live-dealer tables (blackjack, roulette, baccarat, Dragon Tiger), and slot games. As your point balance grows, you advance through loyalty tiers, each unlocking benefits such as faster withdrawal processing, priority customer support, and bonus credit offers. Your current tier and point balance are visible in your account dashboard. You can redeem points for bonus credit or withdraw them as cash in some cases, depending on your tier. Loyalty benefits reset periodically; check your account settings for tier expiry dates and renewal requirements.

We provide grend303 services only in jurisdictions where online gaming is permitted by applicable local law and where we hold proper licensing and regulatory authorization. We do not publicly name specific countries as "legal" or "illegal"; instead, we operate on a licensing basis. If you are unsure whether grend303 is available in your location, consult your local gaming regulator or a qualified legal professional. Access to grend303 is determined by your IP address and payment method location. If we detect access from a jurisdiction where we do not operate, we reserve the right to restrict your account. Services are available only where applicable law permits. For more detail, see our legal notice

Security and account care

Keep your account secure by using a strong, unique password (at least 8 characters, including letters, numbers, and symbols) and never sharing your login credentials with anyone. Do not use the same password on other websites. Enable push notifications in your grend303 app so you are alerted to login attempts and withdrawals. Avoid logging into grend303 on shared devices or public WiFi; use a personal device and a secure network when possible. Review your transaction history regularly to spot unauthorized activity. If you suspect your account has been compromised, change your password immediately and contact our support team. Never respond to unsolicited messages asking for your password, OTP, or payment details — grend303 staff never request this information via email or SMS. See our account security guide for more detail.
