ANDROID PORN BLOCKER. NO BIDS FROM INDIAPAKISTAN REGION. BUDGET $350

i need an app made for child protection. This app is expected to intercept inappropriate words and then block the content. You can either make an app that will have a VPN that will intercept traffic on that phone (without using DNS or an external server) or an app that will substitute the keyboard and intercept keystrokes and when bad words are encountered, it will block prevent bad content from appearing on the phone. You will be expected to make your own UI, which should look nice. Budget $350. ABSOLUTELY NO BIDS FROM INDIAPAKISTAN Your bids are final , no price negotiations after submitting a bid. My budget is $350.
