Privacy

Short version

• Text you type into tools is not uploaded to MorseLabBase for encoding, decoding, or scoring.
• There are no user accounts, passwords, or cloud practice sync.
• Optional local storage may remember theme and trainer preferences on this browser.
• Contact uses your own email client - we do not run a message database on the marketing chrome.

What stays in your browser

Clearing site data, using a private window, or switching devices resets local progress. We cannot restore your Koch set from a server backup - there is not one.

• Encode / decode / timing: memory during the session.
• Audio / flash / vibrate schedules: session only, after your gesture.
• Theme and trainer prefs: localStorage when enabled.
• Challenge plaintext: in the ?c= URL you choose to share.
• Telegraph Desk session log: localStorage on this device - not uploaded.
• Clipboard: only when you click Copy.

What we do not collect for the tools

• No Morse practice transcripts uploaded for storage or model training.
• No microphone capture for AI decode.
• No camera frames for photo OCR.
• No social login or mailing-list wall to use the lab.

Hosting, PWA, analytics, ads

The site is served over the public internet. Infrastructure logs may include IP, user-agent, and requested URLs at the host layer - standard operations, not reading your HELLO WORLD.

PWA: in production, a service worker may cache static assets for offline shell use. Local development does not register a service worker.

Analytics: if a measurement ID is configured, aggregate traffic tools may load. They measure visits and paths - not Morse pane contents.

Advertising: reserved slots may appear when ads are enabled. Ad partners have their own policies. Tool math does not depend on ads loading.

Your choices

• Use a private window if you do not want local trainer prefs to persist.
• Clear site storage to wipe theme / progress keys.
• Block third-party scripts if you prefer - core tools should still run once assets are loaded.
• Do not put secrets into Challenge share URLs.
