Mobile App Development - Upwork

I need the simplest app to use for my partners and no one will be able to see what we are texting. Encrypted communication and no logs. I don't need fancy things, phone calls or anything. Text messages only.

Most Important
1. The highest possible security
2. The highest possible anonymity
3. No logs

We can achieve that by using the 128bit encryption and keys will be stored on our app not on server so this way no one can see the encryption key even someone able to access the server.

We can control the logs on our end to allow the server to generate them or not and same for the app.
We can also implement the functionality of the snapchat auto message deleted so in our case we can delete the message from the server after receiving on the other end but it will remain on the device chat and can remove it from there too.

Upload app on the store's (Android and IOS) but don't publish it, only invited people can install both apps.

- Group functionality:   NO
- Media files (images etc.):   NO
- Calls: NO
**  ONLY text messages

** I think Firebase is ok for hosting (free & fast), for private app (max. users: 20)

Thanks!
