Small software. Serious boundaries.

Stonefern Works is an independent Windows software brand focused on narrow tools that are easy to understand.

The public Stonefern catalog currently includes Relay, Disk Insight, Network Repair, PC Repair, DeskLink, AudioLink, StreamLink, and Subtitle & Audio Cleanup. The capability boundaries are intentionally different: read-only storage inspection, explicit network repair, guided Windows system repair, direct paired-PC communication, private app-audio sharing, Twitch/local media control, and intentional media-file cleanup.

Operating principles

Prefer local processing when cloud infrastructure is unnecessary.
State clearly when a product is read-only and when it can change files, system state, input, display, or network behavior.
Require explicit approval for repair or file-changing actions where practical.
Label release status plainly, including beta releases.
Do not fabricate testimonials, user counts, certifications, or security claims.
Publish product-specific privacy and safety behavior before download.
