Privacy & Data Handling

Overview

HoursCalc is designed with privacy as a core principle. All calculations and user data remain in your browser - we never collect, store, or transmit your personal information or calculation data to our servers.

What Data We Collect

None. HoursCalc does not collect any personal information, calculation data, or usage data on our servers.

Where Your Data Lives

In your browser only. All data is stored locally using:

localStorage

Used for:

  • Recent calculations (last 20 per tool)
  • Saved timesheets (up to 5 named timesheets)
  • User preferences (overtime threshold, time format, etc.)
  • Optional pay rate (if you choose to save it)

IndexedDB

Used for:

  • Timesheet history (last 12 weeks)
  • Detailed calculation history

Important Notes:

  • This data never leaves your device
  • We cannot access this data
  • Clearing your browser data will delete this information
  • Using a different browser or device will not have your saved data

Pay Rate Storage

If you choose to enter and save your hourly pay rate:

  • It is stored only in your browser's localStorage
  • It is never transmitted to our servers
  • It is never shared with any third party
  • Only you can access it on your device
  • You can clear it at any time

Cookies

We do not use tracking cookies. Any browser storage we use is purely functional (localStorage and IndexedDB) to provide the calculator features you use.

Third-Party Services

Vercel Hosting

Our site is hosted on Vercel. Standard web server logs may include IP addresses, browser type, pages visited, and timestamps. These logs are retained by Vercel per their privacy policy for infrastructure purposes only.

Ahrefs Web Analytics

We use Ahrefs Web Analytics for privacy-friendly website analytics:

  • Does not track individual users
  • Does not use cookies
  • Collects aggregated, anonymous traffic data only
  • Complies with GDPR and privacy regulations

No User Accounts

HoursCalc does not require or offer user accounts. There is no registration, login, passwords, email collection, or profile creation.

Your Rights

Since we don't collect your data, there's nothing for us to delete, modify, or export from our servers. You have complete control over your data via your browser:

  • View your data: Browser developer tools (Application tab → localStorage/IndexedDB)
  • Delete your data: Clear browser data or use the "Clear History" buttons in the app
  • Export your data: Use the CSV export features in the calculators

Prefer printable backups instead of digital storage? PlannerCraft generates custom planners so you can archive sensitive schedules offline.

When compliance needs clean data diagrams, DiagramDB helps map how information flows without ever leaving your private workspace.

Summary:

All calculations are performed in your browser. We never see, store, or transmit your timesheet data, hours worked, pay rates, or any personal information. Your privacy is built into the architecture of HoursCalc.
