05DATA & 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.

01 / DATA

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.

02 / TRANSPORT

TLS-encrypted communication

Production domain deployment uses HTTPS/TLS with a trusted certificate. Traffic between LinkDialog clients and the private server is not exposed as plaintext on the network, reducing interception and tampering risk.

03 / ACCESS

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.

04 / INTEGRITY

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.

VERIFIED SCOPE

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.

06WINDOWS OR LINUX SERVER

Multiple client platforms, 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
Best for	Independent Windows host and private network	Cloud server, data center and long-running service
Supported host	Windows 10/11 x64	Rocky/Alma/RHEL-family 8/9, Alibaba Cloud Linux 3, Anolis 8
Access	Local private service by default	Public IP or domain HTTPS
Delivery	Docker Desktop package	Docker deployment archive and scripts

01—04

From environment confirmation to first conversation

Confirm the target

Choose Windows or Linux, local or remote, public IP or domain.

Deploy and activate

Start the private service and activate this server installation.

Issue client configuration

Bind the selected Windows, Android or macOS clients to the approved server, validity period and channel.

Run acceptance

Validate two-user messaging, media, groups, channels, bots and restart persistence.

07CHOOSE BY EXPECTED ONLINE USERS

A clear server starting point for every rollout size.

These are planning targets for a text-led, mostly small-group workload on one server—not verified capacity guarantees. Windows suits smaller installations; Linux is recommended for long-running use.

Compact

Larger teams with higher messaging activity

Online capacity is counted by connected client devices, not registered accounts. One user signed in on two computers counts as two online devices.

Frequent large-group messaging lowers capacity
Heavy file transfers require more bandwidth and storage
AI bots and multiple devices add server load
Run scenario-based load testing before committing to capacity

11BUYER FAQ

Eight questions to answer before arranging a demonstration.

Straight answers about the product source, client platforms, features, security, deployment, delivery and server sizing.

01What exactly is LinkDialog Private IM?

It is a multi-platform private IM product whose Windows client is developed from the open-source Telegram Desktop client. Familiar messaging workflows are recreated on an independently implemented and deployed service.

02Which client platforms are supported?

Windows, Android and macOS clients have all been developed and connect to the same private service. The selected platforms, package formats and signing requirements are confirmed in the delivery scope.

03Does 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.

04Which 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.

05Can 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.

06Can 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.

07How many users can be online at the same time?

The listed figures are planning targets, not tested capacity guarantees. A 4-core 8 GB Linux server may be evaluated for 300–500 devices, 8-core 16 GB for 1,000–2,000, and 16-core 32 GB for 3,000–5,000. Actual capacity depends on group size, files, bots and devices per user, so scenario-based load testing is required before a production commitment.

08Is 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.
