AtmospherePro vs. Everything Else
AtmospherePro FAQs
What is atmospherePro?
atmospherePro is a privacy-first file transfer app created by Atsign that uses true end-to-end encryption. It’s entirely different from other file sharing apps or services because you own the encryption keys!
What does true end-to-end encryption mean?
When you send a file with atmospherePro, it’s encrypted on your device and can only be decrypted by the intended recipient. Since we do not have access to your personal keys, we are unable to access your data. In short, true end-to-end encryption is encryption with no loopholes.
How is atmospherePro different from other file sharing services?
Other file sharing services route files from the sender to their servers and then on to the recipient. And because the service provider has access to the encryption keys, they can access your transferred files—and so can hackers! With atmospherePro you are protected because you hold the encryption keys and your files are not stored* on a server.
*All transferred files are temporarily stored in an encrypted cache until the recipient retrieves the file, for up to seven (7) days. Any files not retrieved are deleted from the server.
Is atmospherePro secure?
Yes it is! Transferred files are temporarily stored in an encrypted cache until the recipient retrieves them. In the unlikely event that someone were to access the files without permission, they would not be able to read them without the keys. Even the app creators cannot view files.
What’s the maximum file size?
At the present time, our maximum file size is 1GB.
Is there a desktop app?
Yes there is! We offer the same secure file transfer system for desktop, too!
Is this an open-source project?
It is! We’re an open-source company and we encourage developers to build their own apps and contribute to the existing atPlatform. Developers may download, modify and repurpose.
