Building VeilComm: Rethinking Private Communication

Building VeilComm

After learning more about how messaging apps handle photos, backups, metadata, and forwarded content, I started asking a simple question:

Can private messaging be designed differently?

That question became the beginning of VeilComm.

Why I Started VeilComm

I wasn't trying to build another messaging app.

I wanted to build something that gives people more control over their own data and make privacy the starting point instead of an afterthought.

For me, privacy isn't only about encrypting messages. It's also about reducing who can access the information you share.

The Idea Behind VeilComm

VeilComm is built around three simple principles:

Collect less.
Store less.
Share less.

The less data that exists, the lower the risk of it being exposed.

What Makes VeilComm Different

VeilComm encrypts messages and files before they leave your device. The encrypted content can then be shared through existing platforms such as WhatsApp, Signal, Telegram, email, or any other service that can transfer files or messages.

Because the content is already encrypted before it is shared, the platform used for delivery does not have access to the original message or file contents. It only carries encrypted data.

VeilComm is not trying to replace existing messaging apps. Instead, it adds an extra layer of privacy that works before your data is shared.

The project also focuses on:

End-to-end client-side encryption.
Secure media and file encryption.
Privacy-focused file handling.
A simple interface that keeps privacy easy to use.

Every feature is designed with one goal in mind:

Give users more control over their own data without making secure communication complicated.

Still a Work in Progress

VeilComm is still under development, and I'm continuing to improve it with every new feature and security improvement.

In future articles, I'll explain how the encryption system works, why I chose this approach, and the engineering decisions behind building VeilComm.

What Happens When You Send a Photo Through Most Messaging Apps?

Sending a photo feels simple. You choose an image, tap Send, and a few seconds later it appears on someone else's phone. Behind that simple action, however, several things may happen that most people never notice.

It Starts on Your Device

The photo already exists on your phone before you send it. Depending on your device settings, it may also be part of your gallery or included in local or cloud backups.

Before the Photo Is Sent

Most messaging apps prepare the image before sending it. They may reduce the file size, create a preview, or optimize it so it can be delivered faster. These steps happen automatically in the background.

Sending the Photo

If the app supports end-to-end encryption, the photo is encrypted before it leaves your device. This helps protect the image while it is traveling across the internet.

After that, the message is routed through the app's delivery infrastructure until it reaches the recipient.

After It Arrives

Once the recipient opens the photo, it exists on their device. Depending on the app and their settings, it may also be saved to the phone's gallery or included in future backups.

At this point, the recipient can also take a screenshot or forward the image to someone else. Encryption protects the photo while it is being transmitted, but it cannot control what happens after the recipient has access to it.

Final Thoughts

When we send a photo, we often think only about the moment we press Send. In reality, there can be several stages between your device and the recipient, and in some cases, multiple copies of the same image may exist over time.

Understanding this process is an important part of understanding digital privacy.

While researching these privacy challenges, I started building VeilComm to explore how private communication could give users more control over their data—not just while it's being transmitted, but throughout its entire lifecycle.

Why Private Messaging Isn't Really Private Anymore

We use messaging apps every day to share photos, videos, documents, voice notes, and even sensitive information like banking details, payment confirmations, passwords, and one-time verification codes. Because many apps advertise end-to-end encryption

it's easy to believe that everything we send stays completely private.

The reality is more complicated.

Encryption protects the content of your messages while they're being transmitted but privacy doesn't end there. Metadata cloud backups screenshots forwarded media and stored copies can all affect how much of your personal information remains under your control.

What Is Metadata?

Metadata usually doesn't reveal the content of your messages but it can still paint a surprisingly detailed picture of your habits and relationships.

Cloud Backups Can Become Another Copy

Many messaging apps automatically back up chats and media to cloud storage.

This is convenient if you lose your phone, but it also means another copy of your private data may exist outside your device. If those conversations include banking information, identity documents, or payment records, that sensitive data may also become part of those backups depending on your settings and the service you use.

Screenshots and Forwarded Media

Even if a message is encrypted, nothing stops someone from taking a screenshot after opening it.

The same is true for forwarded photos, documents, or videos. Once they leave the original conversation, you often lose control over where they go next. Encryption protects data while it's being transmitted, but it doesn't automatically prevent what happens after someone receives it.

Final Thoughts

Private messaging is about more than encrypting the content of a conversation. Metadata, cloud backups, screenshots, and forwarded media all play a role in how much control you actually have over your personal information. Understanding these privacy challenges is the first step toward making better choices about how we communicate online. In the next article we'll follow the journey of a single photo and explore what can happen after you press Send.

The reality is more complicated.

What Is Metadata?

Your message may be encrypted but every conversation also creates metadata. This can include when a message was sent who communicated with whom how often conversations happen and what type of device is being used.
Metadata usually doesn't reveal the content of your messages but it can still paint a surprisingly detailed picture of your habits and relationships.

Cloud Backups Can Become Another Copy
