Terms of Service - CertAlert

Last updated: April 1, 2026

Article 1 — Agreement to Terms

By downloading, installing, or using CertAlert (the "App"), you ("User") agree to be bound by these Terms of Service ("Terms"). If you do not agree, please do not use the App.

The App is a personal certificate and license management tool for tracking expiry dates and renewal reminders. It is not a legal advisory service, government portal, or official certification authority.

Article 2 — No Legal or Professional Advice

The App does not provide legal, regulatory, or professional compliance advice of any kind. All reminders, notifications, and information are for personal reference purposes only and should not be interpreted as:

Legal advice regarding certification requirements
Official confirmation of license validity
Professional compliance guidance
Government-endorsed certification tracking
Guaranteed accuracy of expiry date notifications

Users bear full responsibility for verifying their certificate and license status with the relevant issuing authorities. The developer ("Provider") is not a legal advisor or licensing authority.

Article 3 — Disclaimer of Warranties and Limitation of Liability

The App is provided "as is." To the maximum extent permitted by applicable law, the Provider is not liable for:

Indirect or incidental damages arising from use or inability to use the App
Data corruption, loss, or deletion
Missed renewal deadlines or expired certificates
Fines, penalties, or loss of income resulting from expired licenses
Business interruption

This disclaimer applies only to the extent permitted by mandatory consumer protection laws. It does not apply to damages caused by the Provider's willful misconduct or gross negligence.

Article 4 — Data Loss and Backup Responsibility

To the maximum extent permitted by applicable law, the Provider is not liable for data loss or corruption resulting from:

App crashes or bugs
Device failure, loss, or theft
Software updates
Backup or restore failures

      Always create a backup before changing devices or uninstalling the App. Your certificate data is stored on your device. If you turn on the Pro cloud backup, encrypted backups are saved to your own Google Drive.
    

Article 5 — Reminder Accuracy Disclaimer

Users explicitly acknowledge and agree that:

Push notification reminders depend on device settings and OS behavior, and may not always be delivered
The App relies on dates entered by the User — incorrect input will result in incorrect reminders
The Provider does not guarantee that all reminders will be delivered on time or at all
Users should not rely solely on the App for critical deadline management
Regulatory requirements for certificate renewal may change without notice from the issuing authority

Article 10 — Changes to Terms

The Provider may modify these Terms. For material changes, reasonable prior notice will be given via an app update or in-app notice. Continued use of the App after changes constitutes acceptance of the revised Terms.

The Provider reserves the right to:

Modify, suspend, or discontinue the App
Update system requirements
Change Pro features or pricing (with reasonable prior notice)

App Discontinuation

If the App is permanently discontinued, the Provider will:

Notify users at least 14 days in advance via an app update or in-app notice

      Your data is safe: All certificate records are stored locally on your device. Discontinuation of the App does not affect your data in any way.

The Provider may suspend or terminate a User's access for:

Material breach of these Terms
Fraudulent or illegal activity
Other compelling reasons

Article 12 — Indemnification

Users agree to indemnify and hold the Provider harmless from any claims, losses, or damages arising from a breach of these Terms or misuse of the App.

Article 13 — Dispute Resolution and Governing Law

These Terms are governed by the laws of Japan. Disputes arising from these Terms or use of the App shall first be resolved through good-faith negotiation. If unresolved, the Tokyo District Court shall have exclusive jurisdiction as the court of first instance.

Where mandatory consumer protection laws apply, those laws shall take precedence.

Article 14 — Severability

If any provision of these Terms is found to be unenforceable or invalid, that provision will be modified to the minimum extent necessary and the remaining provisions will continue in full force.

By using the App, you confirm that you have read, understood, and agreed to be bound by these Terms of Service.
