Privacy Policy

Last updated: February 28, 2026

Overview

We do not collect personal data. DeepClock runs entirely in your browser. There are no user accounts, no login, and no server-side data processing.

Local Storage

Your preferences, timer states, and session data are stored in your browser's localStorage. This data never leaves your device, is not shared with any third party, and can be cleared at any time via browser settings or the Settings page.

Analytics & Third Parties

DeepClock uses these third-party services:

  • Vercel — Hosting, anonymous analytics (page views, performance metrics). No cookies or fingerprinting. See Vercel Privacy.
  • Google Fonts — Font loading. Google may log basic request metadata. See Google Privacy.
  • Resend — Delivers feedback emails. Only message text and page URL are transmitted.

No cookies, tracking pixels, or advertising are used by DeepClock.

Your Rights

Since no personal data is stored on any server, you have full control. All data is in your browser's localStorage — accessible, exportable, and deletable at any time. Use a private/incognito window to prevent any analytics collection.

Changes

We may update this policy. Changes are reflected on this page with an updated date.
