Short version: we collect anonymous GPU stats. Nothing personal. That's it.
When you click “Run All Benchmarks,” we save:
Collected data builds an aggregate picture of WebGPU compute performance across real-world hardware. We may publish aggregate statistics (e.g. “median throughput on M2 Macs is X gen/s”) in research papers or public reports. Individual benchmark submissions are never published or shared.
The benchmark shaders run entirely on your GPU inside your browser. No computation is offloaded to our servers. Only the final results (throughput numbers and hardware info) are transmitted after the benchmarks complete. We use Vercel Web Analytics to count page views and referrers. No cookies or personal data are collected.
Benchmark results are stored indefinitely as anonymous records. Because no personal information is attached, individual records cannot be identified or deleted.
The research line and the end-to-end projects that build on it.
The research line. Two published preprints, one npm SDK, 92 unique devices across 7 GPU vendors. The theory that all the applied projects build on.
Electron track-structure simulation ported from the CNRS/IN2P3 Geant4-DNA toolkit to WebGPU. One thread per primary, full 10 keV history in a single for-loop. Radiolysis chemistry and DNA damage scoring live in a browser tab.
