Your desk. Your data.

Stored on this browser

Your subjects, timer settings and study history are stored in your browser on this device. DEe has no account system, shared study database or cloud sync. Other devices do not automatically receive your progress. People using the same browser profile on this device may see it.

Your controls

Use Export history to download a JSON copy of your records. This beta does not yet restore backups. To remove all DEe data, clear this site's storage in your browser settings. Clearing storage or using private browsing can erase your progress.

Notifications and voice

Desktop notifications require your permission. You can revoke it in browser settings. Optional voice selects an English voice reported as on-device by your browser. If none is available, no online voice is used. Keep the tab open and device awake for timer alerts.

Hosting

The application does not include advertising, analytics scripts or payment processing. The hosting provider may process ordinary request information, such as IP addresses, and set security cookies for delivery and abuse prevention under its own policies.

Security limits

Browser storage is not an encrypted vault. Do not store passwords, payment details or sensitive medical information here. Anyone with access to your browser profile, or malicious software on your device, may access local records. No website can promise absolute security.

About this beta

DEe is a study aid, not a guaranteed alarm service. Please keep a separate copy of important records. This free beta does not require a purchase.
