About this app

Plasma is a secure messenger that allows private chatting through QR codes.

With Plasma, you can chat with anyone only after scanning their QR code. QR codes are automatically generated on websites where Plasma is connected and where people you want to chat with are registered.
If you want to set up a space, contact us for more info.

Plasma focuses on the safety and privacy of users, which is why:
- All messages are end-to-end encrypted for protection
- Encryption keys are generated locally on your device, so that no third party can access them
- Your Plasma account isn’t linked to a phone number, so we don’t ask for it
- No one can find you by searching for your nickname

You can join what we call “spaces”. Any service, company, or organization can create a space with an unlimited number of people in it. 
To join a space and chat with its members, you need to scan this space’s QR code with Plasma’s built-in scanner. A QR code is automatically generated on a website where Plasma is connected.

To chat with someone from a particular space:
- Join the space by scanning its QR code
- Scan the person’s QR code to start a dialogue

You need to know on what websites you can find the Plasma QR codes of those who you want to chat with.

When browsing on your phone, you can use direct links instead of QR codes to join a space or start a dialogue. Again, you need to know where to find Plasma links you’re looking for.

All your dialogue data is stored on your device. This includes text messages, photos, videos, and contacts. Only you have access to your dialogues, and no one else, even Plasma.
If you delete a dialogue or leave a space, you’ll lose all data associated with it.

Photos and videos are not automatically saved to your device. So no one can accidentally see something in your phone’s Gallery that you don’t want seen.

The app has functioned well at times, and not so well at times. The intended recipients would report back to me that they never received the photos or videos that show as successfully transmitted to their account on my end. The app recently began randomly shutting down repeatedly when I tried to use it. I uninstalled it and reinstalled it and now I can't use it at all. Plus all of my previous messages and photos and videos are gone.

This app has it's issues.. a good concept, and I use it frequently throughout every day. The main issues I've had are It seems to work fine one day, then the next day it's glitchy. Example for months it wouldn't save pics to my gallery. Then up until yesterday it would save videos, but today, it crashes everytime I attempt to save a pic or video to my gallery. It seems to be sending and receiving okay, today.

Yes I just want to provide some feed back. There needs to be more customisation with the look of it font and size in particular and it should also order the messages by when received or make there options to make our own order.
