WHY CUSTOMERS CHOOSE IT
Keep the desktop habits users already understand. Replace the public service with a private one.
Starting from the open-source Telegram Desktop Windows client reduces the cost of relearning a messaging product. LinkDialog Private IM connects that familiar experience to its own server stack, giving organizations control over branding, deployment, bots, AI and day-to-day operations.

DATA & COMMUNICATION SECURITY
Keep data in your environment and protect communication through an encrypted channel.
LinkDialog Private IM runs on a customer-controlled private server and does not route conversations through the public Telegram network. Its security controls are concrete, reviewable and included in deployment acceptance.
Customer-controlled data
Accounts, messages, files and operational data remain on the customer's private server and storage instead of a public Telegram account or third-party IM service.
TLS-encrypted communication
Production domain deployment uses HTTPS/TLS with a trusted certificate. Traffic between the Windows client and private server is not exposed as plaintext on the network, reducing interception and tampering risk.
Authenticated access and limited exposure
Downloads require authorization, the database port stays off the public internet, and the administration console can be restricted to a trusted network, VPN or additional access control.
Encrypted and signed configuration
Customer client configuration uses AES-256-GCM encryption and RSA-PSS/SHA-256 signatures, allowing the client and server to reject damaged, forged, inactive or expired configurations.
Security is verifiable: server ownership, data location, certificate status, exposed ports, access permissions and backup settings can all be checked during delivery. This describes encrypted client-to-server transport and does not claim unverified end-to-end encryption.
WINDOWS OR LINUX SERVER
One Windows client, two practical server paths.
Choose Windows for a familiar Windows operations environment, or Linux for long-running cloud and data-center deployment. Offline images and guided scripts are included.
| Decision | Windows server | Linux server |

CHOOSE BY EXPECTED ONLINE USERS
A clear server starting point for every rollout size.
These single-server estimates assume a text-led workload, mostly small groups and one connected Windows device per user. Windows suits smaller installations, while Linux is recommended for long-running use.

BUYER FAQ
Seven questions to answer before arranging a demonstration.
Straight answers about the product source, features, security, deployment, client delivery and server sizing.
01What exactly is LinkDialog Private IM?+
It is a private Windows IM product developed from the open-source Telegram Desktop client. Most familiar desktop workflows are recreated on an independently implemented and deployed service.
02Does it connect to Telegram accounts or the public network?+
No. LinkDialog Private IM uses its own private server and does not promise interoperability with Telegram accounts, conversations, bots or the public network.
03Which core features are included?+
Login, multi-device sessions, direct messages, contacts, groups, channels, images, files, voice, saved messages, administration, Bot creation, AI replies, feed bots, channel attribution, backup and restart persistence.
04Can the server run on Windows and Linux?+
Yes. Windows 10/11 with Docker Desktop supports Windows-based private deployment. The Linux package supports the documented RHEL-family systems and is recommended for cloud servers and long-running services.
05Can sensitive communication be captured as plaintext in transit?+
With HTTPS/TLS enabled and the server certificate correctly validated, traffic between the Windows client and private server is encrypted and is not exposed as plaintext on the network. This reduces interception and tampering risk. Data stays on the customer-controlled server and is not routed through the public Telegram network. This is transport encryption, not a claim of end-to-end encryption.
06How many users can be online at the same time?+
As a single-server sizing reference, a 4-core 8 GB Linux server is suitable for roughly 300–500 online devices, an 8-core 16 GB Linux server can be evaluated for 1,000–2,000, and a 16-core 32 GB Linux server for 3,000–5,000. Actual capacity depends on group size, files, bots and devices per user, and is confirmed by pre-delivery load testing.
07Is a signed installer included?+
Yes. The Windows client is delivered as a production Release build with code signing and an installer, together with customer-specific server connection configuration.
