YOUR ACCOUNT IS SECURE

How the otto4d App Protects Your Account

Security on your phone matters. The otto4d app uses industry-standard encryption, code signing and account-recovery tools to keep your balance safe and your login under your control.

Code-Signed Installation

The otto4d app is cryptographically signed by our studio. Your phone verifies the signature before installation, so you know the app you're running is genuine and hasn't been modified.

Official Stores Only

We distribute the otto4d app through Google Play, Apple App Store and our official website at otto4d.app. We never list the app on third-party stores, keeping your installation safe from counterfeit copies.

Encrypted Wallet Connection

All communication between your phone and our servers uses TLS 1.3 encryption. Your payment details and account balance are never transmitted in plain text, even over public WiFi.

Biometric Lock Option

Enable fingerprint or face recognition to lock your account on your phone. If someone else picks up your device, they cannot open otto4d or access your wallet without your biometric consent.

Account Recovery Tools

Forgot your password? Use the recovery email linked to your account to reset it in seconds. Two-factor authentication is optional and recommended for high-balance accounts.

Payment Provider Verification

When you deposit via Touch 'n Go, GrabPay, Boost dan FPX, our system confirms the transaction with your bank or e-wallet provider. Fraudulent deposits are blocked before funds reach your account.

APP VERSUS MOBILE BROWSER

Why Download the App Instead of Using Your Browser

The otto4d app and mobile website are both real options, but the app delivers speed, notifications and offline features the browser cannot match.

Push Notifications

App sends live alerts when your favourite tables go live. Browser has no notification system — you must visit the site to see what's running. Saves time if you play multiple sessions daily.

Login Speed

App uses biometric login with no password entry. Browser requires username and password every time your session expires. One-tap access on the app keeps friction minimal.

Offline Lobby Preview

App caches the lobby, so you can browse games and tables even without an internet connection. Browser requires a live connection to display anything, including game tiles.

Storage & Battery

App is 30 MB and uses less battery than a browser tab left open all day. Browser tab stays active in RAM, draining your phone's power faster during long sessions.

Quick Deposit Widget

App home screen includes a floating deposit button for one-tap loading. Browser requires you to navigate to the wallet section each time. Saves three taps per deposit.

Game Favourites Sync

Star your favourite slot rooms in the app and they appear first on your next login. Browser bookmarks do not sync with our account system, so you lose your list if you switch devices.

The app works on both phones and tablets running Android 8.0+ or iOS 12.0+. Tablets give you a larger screen for live tables and slot games. All features, including live Baccarat and Salon Prive BJ, are identical on tablets.

You can only play one game at a time on a single account. However, you can switch between live tables and slots instantly without leaving the app — just tap a new game and your previous session pauses. Sportsbook bets can stay open while you play slots or tables.

The app uses approximately 15–30 MB per hour of live-table play, depending on stream quality and graphics settings. Slots use less data since they run locally on your device. WiFi is recommended for long sessions to preserve your mobile data allowance.
