According to the [remote storage](https://remotestorage.io/protocol/) protocol, there are 3 types of application/software: #### 1. Traditional Web Apps: In hosted web stacks such as LAMP, .Net, Ruby on Rails, Django, etc…, the developer hosts the app and data, while the user controls device. ![image](https://support.delta.chat/uploads/default/original/2X/b/b5fe7f4a304fdd0fd59457c17e1f78bb82f04ef7.png) #### 2. No-Backend Web Apps In 100% client-side apps that use CouchDB, Hoodie, Firebase, Parse, Kinto, etc…, the developer provides the app and data, while user controls the device. ![image](https://support.delta.chat/uploads/default/original/2X/c/c9df4eed1a34276b78351234a2bb8b5b4964dfed.png) #### 3. Unhosted Web Apps In 100% client-side apps that use remoteStorage, Google Drive, Dropbox, etc…, the developer provides only the app, while the user controls the device and data. ![image](https://support.delta.chat/uploads/default/original/2X/b/b0c5b4e5b5d4d50fb04479d76ee2e9a32b8067a5.png) - What Delta-chat architecture was created and why? - Is delta-chat self-hosted, non-hosted, hosted? ---

depends on whether you use a selfhosted email server or an hosted email account at a big email provider like gmx, gmail, yandex, posteo… the app itself you could describe as unhosted, all data is on your device. ---
