Telegram is a popular messaging app known for its speed, cloud-based architecture, and multi-device support. One of its key features is allowing users to connect multiple devices to the same account simultaneously—such as smartphones, tablets, and desktop computers. This convenience, however, raises questions about what information Telegram stores about these connected devices and how it manages device data from a privacy standpoint. Understanding telegram data what Telegram collects and stores about user devices is important for users who want to safeguard their privacy while enjoying seamless multi-device messaging.

Device Information Stored by Telegram
When you connect a device to your Telegram account, the platform collects and stores specific information about that device to maintain account security, sync messages, and enable notifications. Telegram's data collection policy and user reports reveal that the following device details are typically stored:

Device Type and Model: Telegram logs the type of device you use (such as Android phone, iPhone, Windows PC, or Mac). It may also record the device model to optimize app performance and provide better support.

Operating System and Version: The app records the operating system (OS) your device runs, including the OS version. This helps Telegram manage compatibility and ensure security patches are relevant to your device.

IP Addresses: Each time your device connects to Telegram’s servers, the app logs the IP address. This helps Telegram detect suspicious activity, prevent abuse, and protect against unauthorized access.

Session Details and Activity: Telegram stores data about your login sessions, including timestamps, device names, approximate locations inferred from IP addresses, and whether the session is active or terminated. This lets users view all active sessions and remotely log out any device from their account.

App Version: Telegram keeps track of which app version is installed on each device to troubleshoot problems and roll out updates.

Why Does Telegram Store This Information?
The primary reasons Telegram collects device-related information include:

Account Security: By tracking device sessions and IP addresses, Telegram can alert users to unusual login attempts or multiple active sessions, which helps prevent account hijacking.

Synchronization: Telegram’s cloud-based system syncs messages and media across all connected devices. To ensure smooth syncing, Telegram needs to recognize each device individually.

User Control: Telegram offers a “Devices” menu where users can see all logged-in devices, including device types, locations, and last activity times. This transparency empowers users to manage their account security by terminating unknown or unused sessions.

How Long Is Device Data Stored?
Telegram’s privacy policy states that some user data, including device information, may be retained for a period to prevent spam, abuse, or violations of the platform’s terms of service. While exact retention periods are not publicly specified for device data, users generally can assume that session and device info remain stored as long as the device remains connected to the account or until sessions are manually terminated.

User Controls Over Device Data
Telegram provides users with control over their device sessions through the app settings:

Users can review all active sessions, including the device type, IP location, and last seen timestamp.

Users can terminate individual sessions or log out from all devices except the current one.

The ability to manage sessions helps users keep their account secure and reduce unwanted device access.

Conclusion
Telegram stores various pieces of information about user devices connected to an account, including device type, OS, IP addresses, app versions, and session details. This data enables Telegram to provide a seamless multi-device experience while enhancing account security. Although Telegram retains this information to maintain service quality and prevent abuse, users retain control by monitoring and managing connected devices through the app. Being aware of what device data Telegram stores and actively managing device sessions can help users maximize both convenience and privacy.
