Messaging apps like WhatsApp, Facebook Messenger, and Telegram have largely replaced old-school SMS text messaging. Unlike traditional texts which are transient and temporary, messages sent on these apps are saved indefinitely in the cloud. The default setting for most chat apps is to store all messages on their servers with no expiration date. 

Concerns around persistent chats

Storing personal conversations indefinitely raises a few concerns about privacy and data exploitation. First, hackers or other malicious actors may be able to access your chat history if they breach the security of the messaging app. Second, tech companies can analyze your conversations to target you with ads or sell your data to other parties. And third, if governments demand access to messenger data, they can get a revealing window into citizens’ private lives. Many people are uncomfortable with their communications being archived forever on company servers.

Methods for more private communication

Thankfully, there are ways to communicate more privately using both new tools and features built into existing chat apps. Here are four methods to keep your conversations more secure:

1. Use encrypted messaging apps like Signal or WhatsApp. These apps implement end-to-end encryption so messages to the sender and recipient. While still persistent, encrypted chats offer more protection against hacking, government surveillance, and data exploitation.
2. Enable disappearing messages. Apps like Snapchat and Telegram let you make messages expire after a set period. The recipient can only view the message temporarily before it’s deleted. It prevents conversations from being stored indefinitely in the cloud. 
3. Delete messages after they’re read. In apps like WhatsApp, you can enable a “delete message” setting that erases a message from the cloud after the recipient opens it. While not bulletproof, it reduces the time window for messages to be hacked from company servers.

Convenience vs. privacy trade-off

There’s an inherent tradeoff between the convenience of persistent chats and keeping our conversations private. Storing messages forever makes referencing and searching easy. However it raises privacy concerns and encourages surveillance capitalism business models. Using private communication methods requires more intentional effort from users.

With end-to-end encryption, disappearing messages, and tools like Privnote, we can take back a degree of control over our communication data. Being more mindful of what we share over messenger apps also goes a long way. With the right tools and awareness, we can message apps conveniently while minimizing privacy risks.

 Key to private chats encryption

End-to-end encryption is the most important technical method for keeping persistent chats private. Encryption scrambles messages in transit so the sender and recipient can decipher them. Even the company hosting the chat app can’t read encrypted messages. It prevents hackers, government agencies, and the tech companies them from exploiting private conversation data. 

Some popular messengers like WhatsApp and Signal have implemented end-to-end encryption by default for all chats. Telegram offers a secret chat mode that enables encryption for specific conversations. iMessage also encrypts texts between Apple devices. However, other widely used apps like Facebook Messenger still lack default encryption. Users should educate themselves on which of their messaging apps offer encryption and how to use it properly. Turning on encryption doesn’t make messages safe, but it does provide a strong shield against bulk data collection and automated scanning of conversation content.
