Privacy Policy

Last updated: November 10, 2026

This Privacy Policy explains how Excel Expiry Monitor (“the application”) handles information when it is used to monitor insurance expiry dates in an Excel workbook.

1. Information processed

The application reads the workbook selected by the user on the user's Windows computer. To identify policies that need attention, it processes fields such as vehicle type, vehicle registration/plate number, insurance type, expiry date, and the calculated warning or overdue status. The application is designed not to include policyholder names in alert emails.

2. Where information is stored

The Excel workbook remains on the user's computer. The application keeps its sending and duplicate-prevention log in a local SQLite database on that computer. The OAuth refresh token used to authorize Gmail sending is stored in Windows Credential Manager. This website does not receive or store the workbook, alert records, or OAuth tokens.

3. Email alerts and Google Gmail API

When an alert is due, the application sends a consolidated email to the recipient configured by the user. The email may contain the vehicle type, plate number, insurance type, expiry date, remaining days or overdue status, and alert date. The application uses the Google Gmail API with the gmail.send permission to send these messages. The message is transmitted through Google; Google's handling of email and account data is governed by Google's own privacy terms and policies.

4. Sharing and sale

The application developer does not sell alert information or use it for advertising. The application does not intentionally send workbook contents to the developer or this website. Information included in an alert is disclosed to the email recipient selected by the user and processed by Google to provide the email service.

5. Retention and user control

The workbook and local sending log remain on the user's computer until the user deletes them. The user controls the configured email recipient and can stop the scheduled task or uninstall the application. The user can also revoke the application's Google account access from their Google Account security settings.

6. Security

The application is designed to keep the workbook and OAuth refresh token on the user's computer. Users should protect their Windows account, keep their computer updated, and avoid sharing their local application files or database with unauthorized people. No method of storage or transmission is completely secure.

7. Changes to this policy

This policy may be updated if the application's data handling changes. The revision date at the top indicates the latest update.
