Sending texts and messages are ubiquitous now, but deleting them is nearly impossible because they are saved in the cloud or on someone’s phone.

While you might delete texts from your smartphone or edit messages on Slack, the messaging platforms have likely retained backups in the cloud like iCloud, Otavio Freire, CTO of SafeGuard Cyber, a Charlottesville, Va.-based cybersecurity company specializing in security and compliance solutions for digital communications platforms, told TheStreet.

“When you delete data, you are only deleting it from the device,” he said. “Once you hit send, your data is out there.”
