A dedicated place to talk with family, close friends or a small team. Choose your domain, create accounts for the people you trust, and communicate without using Telegram or WhatsApp for those conversations.
You manage the messenger's users and their access. Our platform runs the hosting and message delivery behind your domain, so you do not need to install or maintain a physical server.
Choose an address that is easy to share with your people. Your domain becomes the address of your messenger.
Open My domains → Domain settings and choose Private messaging server. Open its settings to manage access.
Create a username, real name and password for each person. Share their login details privately. Messenger accounts do not require an email address or phone number.
Visit your domain and sign in, or activate an Android plan and add the domain in Private SMS. People on the same server can contact each other by username.
The server holds a message while it waits for the recipient. Once the recipient's app or browser saves it and confirms receipt, the server removes that message from the delivery queue.
Your device keeps your copy and sends the message over an HTTPS connection.
The message text is encrypted in the server's temporary queue. It waits if the recipient is offline.
Their device saves the message and confirms receipt. The queued text is then deleted from the server.
Undelivered messages expire after 30 days and are removed by cleanup. They are not removed immediately after you press Send.
Attachments are stored separately for download and can remain on the server for up to 30 days after sending. Receiving the text does not immediately erase its attached file.
Each chat account uses one Android device. Signing in on another phone requires confirmation to disconnect the previous one. While a chat tab is active in your browser, delivery to Android pauses. Hide or close that tab to resume delivery to the app. Messages received in the browser stay there; they are not copied back to the phone.
Delivered conversations are kept locally in the app or browser. The delivery queue is not a cloud archive for restoring your complete history on a new device.
Private SMS also includes personal notes for text, photos, recordings and videos. Notes stay on your phone and are not sent to our messaging server.
The app's delete menu lets you clear a conversation, all chats, or all app data including connected servers, with confirmation.
This removes your local data. It does not erase the other person's copy, screenshots, exported files or device backups, and it is not a guarantee of forensic erasure.
Your conversations use your domain and this service; Telegram and WhatsApp are not the delivery platforms for these chats. Access is limited by messenger accounts, and message text is encrypted while stored in the delivery queue.
The current messenger does not use end-to-end encryption. Our server processes message content and holds the encryption key. A compromised server or stolen account password can expose pending or future messages. We cannot promise that messages are impossible to read, intercept or copy.
Recipients can keep or share anything they receive. Delivery records and account information are separate from message text; attachments have their own retention period. Android push notifications use Google Firebase, so the service is not entirely free of third-party infrastructure.
Use unique passwords, protect your phone with a screen lock, and give access only to people you trust.
Web chat is included with your domain. Android plans are billed per messenger domain, per year, and apply to the users on that server. Domain registration and renewal are separate.
Sign in on your domain and chat in a browser.
Use Private SMS for text conversations.
Text conversations and voice messages.
Text, audio, photos, videos and files up to 50 MB each.
Your messenger starts with 10 user accounts. Extra capacity is available in messenger settings. One Android app can connect to up to 10 messenger domains.
Choose your domain, activate the messenger and invite your people.
