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 HOW DO PEOPLE CONNECT ON PLASMA? 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. WHERE IS ALL THE DATA STORED? 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. ## Key features - End-to-end encrypted messaging - Local encryption key generation - QR code based connections - No phone number required for account - Nickname search disabled - Data stored locally on device ## Recent user reviews (10 of 13) All indexed reviews: https://appshunter.io/ios/app/plasma-secure-messenger/id1520164188/reviews.md ### 1/5 — Waste of time. *2024-04-30* Doesn’t work, scam ### 1/5 — Meh *2024-03-20* Why when I receive one message the app sends me 7 notifications one right after the other. Super annoying. Also, there’s no clear way on the app, if any, to contact support. ### 5/5 — +18 *2024-02-09* Me gusta ### 1/5 — Doesn’t work for Stripchat *2023-11-27* Mini models from the website promote the messaging app to message them off-line. I’ve messaged models on Plasma, never get a reply. Tell them when they get back online, they tell me they never got the NOTIFICATION FIX THIS PLASMA ### 1/5 — Doesn’t work for Stripchat *2023-11-18* Mini models from the website promote the messaging app to message them off-line. I’ve messaged models on Plasma, never get a reply. Tell them when they get back online, they tell me they never got the NOTIFICATION FIX THIS PLASMA ### 4/5 — Works great on iPad *2022-03-29, version 4.1.4* I have been using Plasma Messenger for about two weeks now and it works well on iPad OS 15.4 for text messages and image uploads. It will not work at all on my Android 12 Galaxy s20+ 5G phone. It opens then immediately closes. Needs Android 12 support fix. Works wonderful on my iPad though. The official website drastically needs more information! I have not been able to upload nor capture and send video yet. There may be a file size or video duration limit. It goes to upload or send video and I get a “Network Error” message. I have checked and tried nearly everything and it isn’t my network with issues. Frustrating, as sending short video messages would be great. I will try shorter clips like apple seconds long and see it it will work. Please expand your site with information please. A good app with potential to be great with support. ### 2/5 — Messages aren’t being received *2021-05-18* App was great until 17-5-21 when messages stopped being received. The sender has sent me 5 and I have sent them 2 but none have been received. Uninstalled app and reinstalled. Got notification of new message but when opened the app got a “decrypting “ message with spinning icon but nothing more happened. It then disappeared but still no message received. ### 1/5 — Extremely impractical *2021-04-28, version 4.0.2* That there is no way to add someone other than their QR code with your camera. So if a friend sends you a screen shot of their QR code, you can’t add them because you can’t take a photo of your own phone: ### 5/5 — New update breaks *2021-03-24, version 4.0.0* App broke after an update. Used app support link in App Store and got a reply overnight...Also found a fixed app working again the next morning. Quality stuff. I like it. ### 3/5 — Can't Messages or files *2021-03-24, version 4.0.0* The first day I was able to send texts or pictures. Now My messages are not being delivered. It says something like timeout. ## Frequently asked questions about Plasma ### How does Plasma ensure user privacy?
