1. Executive Summary: Zero-Server Payroll Privacy
At WorkHoursCalculator.app (including workhourscalculatorapp.com and the mobile application com.workhourscalculator.app), we believe your work hours, shift schedules, hourly pay rates, and paystub comparisons belong strictly to you.
- We DO NOT transmit, store, or log your timesheet entries or pay rates on any remote database or cloud server.
- All calculations execute 100% locally inside your web browser or mobile device using JavaScript.
- No user account, email signup, phone number, or Social Security Number (SSN) is ever requested or required to use our tools.
2. Local Device Storage (localStorage) & JSON Backups
To prevent accidental data loss when you close or refresh your browser tab, the application uses your browser's native window.localStorage API under three specific keys:
whc_app_state_v1: Stores your current timesheet rows (clock-in, clock-out, break minutes), display name label, hourly rate, overtime rule preset, and rounding preference on your device.whc_live_punch_v1: Stores your active Live Shift Punch Clock timestamp so your timer remains accurate even if your mobile OS puts the browser tab to sleep.whc_theme_v1: Remembers your selected visual theme (Midnight Slate, OLED Carbon, Forest Emerald, Sapphire Navy, or Crisp Daylight).
You may permanently erase all locally stored data at any time by clicking the 🗑️ Clear Sheet button inside the calculator or clearing your browser's site data. For full details on mobile data deletion, see our App Data Safety & Deletion Policy.
3. Server Logs, Analytics & Advertising Cookies
Like most standard web publications, our web hosting infrastructure records basic, non-identifying HTTP request metadata (browser user-agent type, referring page, timestamp, and anonymized IP region) strictly for security, DDoS mitigation, and aggregate traffic reliability.

4. California Consumer Privacy Act (CCPA / CPRA) & US State Privacy Rights
Under the California Consumer Privacy Act (CCPA), as amended by the CPRA, as well as the Virginia CDPA, Colorado CPA, and Connecticut CTDPA, US residents have the right to:
- Right to Know: Request disclosure of the categories and specific pieces of personal information collected. Because our calculator stores all payroll inputs locally on your device, we hold zero personal payroll records on our servers.

- Right to Opt-Out of Sale/Sharing: We do not sell, rent, or trade personal information to third-party data brokers.
