Vivaldi Technologies explains how they managed to stay away from Android’s built-in browser core to protect your privacy and keep users’ data secure at all times, because we’re all aware by now that Google’s code doesn’t really offer the privacy and security levels Vivaldi needs. As such, Vivaldi Technologies built the Vivaldi for Android mobile web browser on top of the latest Chromium code using in-house developed alternatives to Google’s web browser core for Android. This allowed them to implement their Sync functionality without using the Google Sync server to keep your data secure.
