Telegram vs. WhatsApp: How They Handle User Data
Posted: Thu May 29, 2025 5:44 am
In the realm of messaging apps, privacy and data security are among the most critical concerns for users. Telegram and WhatsApp are two of the most popular platforms, but they differ significantly in how they handle user data. Understanding these differences can help users make informed choices about their privacy.
Data Collection and Storage
WhatsApp, owned by Meta (formerly Facebook), collects telegram data certain user data primarily for service provision, security, and personalized advertising. It keeps logs of your phone number, contacts, device information, and usage patterns. Notably, WhatsApp applies end-to-end encryption to messages, meaning only the sender and receiver can read the contents. However, metadata—such as who contacted whom and when—is stored on WhatsApp servers. This metadata can be used for advertising and other analytical purposes by Meta.
Telegram, on the other hand, emphasizes privacy more strongly. It also collects basic user information like phone number and contacts, but it minimizes data storage. Telegram’s servers are distributed globally, and the platform offers secret chats that are end-to-end encrypted, with messages that are not stored on Telegram’s servers after delivery. Regular chats are stored on Telegram’s cloud servers, but they are encrypted and accessible only to the user, with Telegram claiming they cannot read these messages.
End-to-End Encryption and Privacy Features
WhatsApp’s hallmark is its default end-to-end encryption for all chats, which ensures that only sender and recipient can decrypt message content. Despite this, WhatsApp collects and stores some data on its servers, including contact lists and usage logs, which are shared with Meta for targeted advertising and analytics.
Telegram offers a unique approach. Its default chats are Cloud-based but not end-to-end encrypted, meaning Telegram’s servers can access these messages. The platform’s emphasis is on cloud convenience and synchronization across devices. For users who prioritize privacy, Telegram’s secret chats provide end-to-end encryption, but these are optional and need to be initiated deliberately.
Data Sharing and Privacy Policies
Meta’s business model for WhatsApp relies significantly on user data for advertising and building user profiles, despite claims that WhatsApp messages themselves are private and encrypted. WhatsApp shares some data with Meta, including usage data, device info, and transaction data, which can be used to target ads across Meta’s network.
Telegram has a different approach. It states that it is less reliant on advertising and does not sell user data. Its privacy policy emphasizes that user data is stored only as long as necessary and is protected from third-party access. Telegram also supports advanced privacy features like two-step verification, anonymous forwarding, and self-destructing messages.
Security Concerns and Critical Perspectives
While WhatsApp’s encryption is robust, privacy advocates have raised concerns about metadata collection and data sharing practices. Critics argue that, despite encryption, the extensive data collection and sharing with Meta compromise user privacy.
Telegram’s open-source-based protocol and optional end-to-end encryption are viewed favorably by privacy-conscious users. However, since most chats are not end-to-end encrypted by default, some critics question the platform’s security for sensitive communications outside secret chats.
Conclusion
In summary, WhatsApp and Telegram employ different strategies regarding user data. WhatsApp emphasizes convenience and integrated features, backed by default end-to-end encryption but centralized data collection and sharing with Meta. Telegram offers greater privacy options, particularly through its secret chats and limited data sharing, positioning itself as a more privacy-focused platform. Users prioritizing privacy may prefer Telegram’s approach, while those seeking seamless integration and end-to-end encrypted chats may lean toward WhatsApp. Ultimately, understanding each platform’s data policies helps users make choices aligned with their privacy concerns.
