PrefrontTerms of service
Plain-language terms for using Prefront. The spirit of it: be reasonable, and don't treat a game as a medical device.
The service is provided as is
Prefront is offered "as is" and "as available", without warranties of any kind, express or implied. We work to keep it fast and reliable, but we don't guarantee it will be uninterrupted, error-free, or available at all times.
Not medical advice
Prefront is a training and tracking tool, not a medical product. Your scores are for personal reference only — they are not a diagnosis, a clinical assessment, or medical advice. We don't claim to raise IQ, prevent cognitive decline, or treat any condition, and you should be skeptical of any app that does. If you have concerns about your cognition or attention, talk to a qualified professional.
Your data is your responsibility
Because your training history lives in your own browser's local storage, it's under your control — and your responsibility. Clearing browser data, switching devices, or using private browsing will reset it. We can't back it up or restore it for you.
Acceptable use
Use Prefront for personal, non-commercial training. Don't attempt to disrupt the service, abuse the feedback channel, or misrepresent the app or its results.
Content and copyright
The Prefront name, logo, design, and written content on this site are the property of the site owner. You're welcome to link to the site and share your own results; please don't copy the app or its content wholesale without permission.
You can stop anytime
There are no accounts and no subscriptions. To stop using Prefront, simply close the tab. To remove your data, clear your browser's local storage for this site.
Limitation of liability
To the maximum extent permitted by law, we are not liable for any indirect, incidental, or consequential damages arising from your use of Prefront — including lost data, lost time, or any decisions made based on your training scores.
