You are handing over the keys to your entire digital life just to send a single PDF. And it’s time to stop.

This is why we built SEYFR: you deserve to stay in charge of your most important files.

One week after SEYFR’s first public release, we saw interest from several countries. That was encouraging—but our early wording confused website traffic with verified product use. This is the corrected account.
Our website analytics showed visitors from the United States, United Kingdom, Mexico, Finland, the Dominican Republic, Uganda, Germany and Poland. Website location data is approximate, and a visit does not prove that somebody installed the app or completed a transfer.
The evidence we can responsibly separate is:
Those are useful signals, but they are not interchangeable.
SEYFR transfers user-selected files between supported Android, iPhone, iPad, macOS, Windows and Linux devices. It uses Iroh networking to attempt a direct, encrypted connection. When a direct route is unavailable, Iroh can use an end-to-end encrypted relay that forwards the bytes without being able to read the file contents.
SEYFR does not require a SEYFR account or a JITPOMI cloud-drive upload. It sends the selected bytes without intentional recompression. A QR code or transfer token carries connection directions and a 32-byte BLAKE3 content hash—not the file itself.
We should therefore not describe every transfer as “always direct,” “serverless,” or guaranteed to run at the maximum possible speed. Network conditions, device storage, platform limits and relay availability all matter.
SEYFR is now available through Google Play, the Apple App Store and Mac App Store, Microsoft Store, and a Linux download. External users have reported successful transfers, including a test between the United States and Australia. Our YouTube channel also documents real transfers under the conditions shown in each video.
Distribution remains the challenge. Store availability proves that people can obtain the product; it does not prove that enough people are discovering, installing or retaining it. That is why we now measure the journey separately: source → website visit → store click → store-reported acquisition or install.
Early attention is not the same as adoption. Our job is to publish evidence, label it correctly and improve from what the numbers actually show.
