The Deal

You give

Timing patterns and check-ins. We never see the content of what you type - only the rhythm.

You get

Free desktop preview access, a personal baseline view, and clear updates on what the signal gets right or wrong.

The honest summary

During the Research Preview, aggregate data leaves your computer so we can test whether the signal works. If validation earns a v1.0 score, the goal is local-only detection.

What data does TypeFuel collect?

During the Research Preview, TypeFuel collects per-minute aggregates that help test whether a cognitive fatigue tracker can work without a wearable or surveillance. The desktop app summarizes keyboard timing, correction patterns, research-only cursor rhythm metrics, active and idle rhythm, and short 1-7 fatigue check-ins. It does not store raw keystrokes, typed content, app names, window titles, browser URLs, screen contents, file names, contacts, microphone, camera, manager activity, or team activity. Preview data exists to test the signal, not to score productivity or monitor employees. Email signup data is used only for Desktop Preview communication and stays separate from behavioral research data. In v1.0, if validation earns it, the goal is local detection so behavioral data stays on the user's computer. Until then, preview participants can pause collection, export what they have contributed, withdraw, and request deletion.

Keyboard timing and correction patterns. Research-only cursor rhythm metrics. Your 1-7 fatigue check-ins. An optional context note when you submit one.

What we send is computed once per minute, not streamed live.

Where it goes

Aggregated timing patterns and check-ins go to our research server. Access is restricted to two named researchers. Retention is 12 months from collection. You can delete everything at any time and we wipe it within 30 days.

A stable per-user ID lets us compare you against your own past. We don't tie it to anything personally identifiable.

Your controls

• Pause collection any time from the menu bar / system tray.
• Export everything you've contributed in one click.
• Delete everything you've contributed in one click.
• Withdraw and we wipe your data within 30 days.

What we'll do with it

Test the detection signal. Publish aggregate findings. Nothing else: no selling, no advertisers, no third-party sharing, no individual reports. See the Roadmap for what TypeFuel will and will not become after the preview.
