Privacy Policy for Work Day Calculator
Last Updated: October 2026
Welcome to Work Day Calculator ("the App", "we", "us", or "our"). We are committed to protecting your personal privacy. This Privacy Policy outlines what information the app processes, how it is used, and how your data remains secure.
1. Information We Store and Where It Is Kept
Your work data is 100% private and stored locally on your device:
• Work & Shift Logs: Dates worked, start/end times, regular and overtime hours, leave records, and user notes are saved exclusively in a local database on your device.
• Financial & Salary Configurations: Basic salary settings, overtime hourly rates, allowances, EPF percentages, and advance payments entered by you remain strictly on your local device.
• Photos & Attachments: Roster or receipt photos captured or imported into day entries are saved exclusively in your phone's private app storage.
• No Central Cloud Server: We do not operate a remote server, and we do not transmit, collect, or sell your personal work or financial data.
2. Biometric & App Lock Security
The App offers optional Biometric (Fingerprint) and 4-digit PIN authentication to safeguard your records:
• Biometric verification is handled entirely by the Android Operating System's secure hardware (BiometricPrompt API).
• The App never accesses, collects, or transmits your actual fingerprint or biometric data. The OS simply returns a cryptographic confirmation of success or failure.
• Your PIN is stored locally in protected encrypted device preferences.
3. Third-Party Advertising (Google AdMob)
To keep the App free to use, we display non-intrusive advertisements provided by Google AdMob (Google LLC):
• Google AdMob may collect and process pseudonymous identifiers such as the Google Advertising ID (AD_ID), IP address, and approximate device information to serve relevant ads and prevent fraud.
• Google's use of data is governed by the Google Privacy & Terms for Advertising (https://policies.google.com/technologies/ads).
• You can reset or opt out of personalized ads at any time via Android Settings > Google > Ads.
4. Permissions Used by the App
• Internet & Network State: Used exclusively by Google AdMob to load advertisements.
• Post Notifications: Used only on Android 13+ to display download completion alerts (for PDF and CSV reports) and optional daily logging reminders that you schedule.
• Exact Alarms & Boot Completed: Used to reliably reschedule your personal daily logging reminders after your phone restarts.
• Biometric / Fingerprint: Used solely to unlock the App upon launch if you enable App Lock.
5. Data Export, Backup & Deletion
You have absolute control over all your records:
• Export: You can export your data at any time to PDF or CSV format.
• Backup & Restore: You can create encrypted local JSON backup files.
• Full Deletion: You can delete any individual record or clear all application data instantly via Settings > Data > Clear All Records.
6. Children's Privacy
Work Day Calculator is designed for working adults and professionals managing work shifts and wages. We do not knowingly collect personal information from children under the age of 13.
