Android App

Hello, I need to know the possibility of building an app to make this actions on a mobile device: • Eliminate a contact from the phone directory and include it again, based on a calendar that contemplates day and hours. This contact should be blocked once the number is eliminated, so the phone shouldn’t receive calls or texts from that phone number, until it’s added again on the register. • Eliminate the sms and mms from this contact, when the number is eliminated, accordingly to an adjustable calendar. • Eliminate the calls history, when the number is eliminated, accordingly to an adjustable calendar. • Eliminate the whatsapp messages from the contact, when the number is eliminated, accordingly to an adjustable calendar (days and hours). • Block the contact after the elimination and add it again accordingly to an adjustable calendar. • Eliminate the Facebook messages from a contact accordingly to an adjustable calendar (days of the week and hour). • The app must be hidden and should be managed on line. • The app must have user and password to manage the profile and choices on line. • Eliminate all attachments (documents and/or images) sent in Whatsapp/Messenger/LINE/Telegram/Hangouts and create a backup of these data on a cloud, associated to the profile, managed on line.
