Contacts!
Actually, allowing the app to access the contacts is a big issue. I found out this company stores the name, number and maybe extra info in their servers when they claim they dont. One way to prove it is when you save a contact in your phone with any name like for ex. "Abc" and any number "123-xxx-xxxx" and if other people have in their contacts stored the number "123-xxx-xxx", it will automatically show the name "Abc" on their phones so the name and number is stored in a server for sure. You will notice in the app duplicate names or names that arent in your contacts. If this company have all this info, the government, anyone with access to their servers or any other entity can track you through your friends or they can be tracked through you. The government or any hacker just need a number and a name to access all peoples life with the help of other softwares. I know this because Ive witnessed a couple of programs working for security purposes. It isnt safe at all! It should use another type of ID like a PIN number or an username in order to avoid tracking and then hopefully be 100% secure in all aspects. The app does a great job when it comes to encryption, though. I hope they change this method soon and stop accessing to contacts list.
Every app that accesses your contacts list has the free option of keeping them in their servers. They have access to names, phone numbers, emails, birthdays, profile picture and more by default from your list. If they want they can have the app modify them, too. So giving contacts access to any company or app is a big risk. BE VERY CAREFUL WHEN DOING SO!
