The Engineering Behind PhotonFile

PhotonFile is a purpose-built system for private, temporary sharing. Built in C++ for control over performance and memory, with a design that avoids retention by default.

Built in C++
The entire app is native C++. That choice gives full control over memory lifecycle and data flow. There's no interpreter or heavyweight framework between your file and the wire.
In-Memory Transfers
Transfers move through memory only. Files aren't written to disk, indexed, or queued for later. When a transfer completes, the data is gone.
No Storage Layer
PhotonFile doesn't depend on object storage or background replication. Each relay runs with zero-retention by design, so there are no silent backups or stray copies to clean up later.
Performance as Privacy
Less time in transit means less exposure. The relay I/O is tuned for high throughput without caching or job queues. Speed isn't just convenience here, it reduces the window of risk.
Engineered to Forget
Built to forget, not to remember.

Every decision, from connection handling to how TLS is layered serves that principle. Minimize surface area. Minimize lifetime.

What We Don't Share
For security and competitive reasons, we don't publish internal network layout, server images, or key handling details. The important part for you: the system is designed so we don't retain your data.
