What Is Metadata, and Why Does It Matter for Your Privacy?

When you send a message or post online, you might assume that the content itself is the only thing that matters. However, there's another type of data that's often overlooked: metadata. Metadata is information about the message, such as who sent it, when it was sent, and where it was sent from. Even when message content is protected, metadata can reveal a great deal about your online activities.

What is metadata, exactly?

Metadata is data about data. It's the information that describes the characteristics of a message, such as its size, format, and transmission details. For example, when you send an email, the metadata might include the sender's email address, the recipient's email address, the subject line, and the date and time the email was sent.

Why does metadata matter?

Metadata can be just as revealing as the message content itself. For instance, if you send an email to a sensitive recipient, the metadata might reveal that you're communicating with someone about a specific topic or at a particular time. This can be problematic if you're trying to keep your online activities private. Even if the email content is encrypted, the metadata can still be accessed and used by third parties.

Why do data-minimizing services collect as little metadata as possible?

Data-minimizing services like Howdlo aim to collect only the information necessary to provide a service, and keep it only as long as necessary. This approach reduces both privacy risk and the impact of any breach. By collecting less metadata, these services minimize the amount of data that could be compromised in the event of a security incident.

How does Howdlo protect your metadata?

Howdlo is committed to protecting your metadata. The service uses Latchline to encrypt your messages in transit and at rest, using a separate key for each conversation. This means that even if stored data were ever exposed, your messages would be scrambled and not readable. Additionally, Howdlo's servers unscramble messages in memory when needed and re-seal them at rest, ensuring that your metadata is protected.

What can you do to protect your metadata?

While data-minimizing services like Howdlo do their part to protect your metadata, there are steps you can take to further safeguard your online activities. Use a secure email provider, enable two-factor authentication, and be cautious when clicking on links or downloading attachments from unknown senders. You can also use a VPN to mask your IP address and location.
