Terms of Service

Last updated: April 17, 2026

Article 1 — Agreement to Terms

By downloading, installing, or using DriveLedger (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 mileage logging tool for record-keeping purposes. It is not a tax advisory service, tax filing service, accounting platform, or legal consultation tool.

Article 2 — No Tax or Legal Advice

The App does not provide tax, legal, financial, or accounting advice of any kind. All calculations, mileage rates, deduction estimates, statistics, and reports generated by the App are for reference purposes only and should not be interpreted as:

Tax filing guidance or advice
Legal opinions or compliance certification
Accounting consultation
Official deduction calculations for tax authorities
Professional financial planning

Users bear full responsibility for their own tax filings and record-keeping accuracy. The developer ("Provider") is not a tax advisor, accountant, legal professional, or agent of any government agency.

⚠️ DriveLedger is an independent app and is not affiliated with, endorsed by, or connected to the IRS, CRA, HMRC, ATO, or any tax authority. Mileage rates are reference values based on publicly available rates at the time of the app's release and may change — always verify current rates with your tax 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
Rejected tax deductions, audit outcomes, or missed tax savings
Inaccurate mileage rates or calculation results
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
Cloud storage provider outages (Google Drive)

      💡 Always create a backup before changing devices or uninstalling the App. All data is stored only on your device unless you enable cloud backup.
    

Article 5 — Accuracy of Mileage Rates and Calculations

While the Provider strives to provide accurate calculations and current mileage rates:

Mileage rates are reference values sourced from public IRS / CRA / HMRC / ATO publications at the time of the app's release and may not reflect the most current rate
Users are responsible for verifying current rates directly with their tax authority (e.g. irs.gov)
No warranty is made regarding the accuracy of distance calculations, deduction estimates, or any other computations
Users must independently verify all calculations and rates before filing tax returns or submitting expense reports

Article 6 — User Obligations and Prohibited Activities

Article 7 — Third-Party Services

The App integrates with the following third-party services. The Provider is not responsible for the actions, fees, or policies of those services. Your use of third-party services is subject to their own terms and privacy policies.

RevenueCat, Inc. — subscription management and purchase receipt validation. RevenueCat receives an anonymous identifier and purchase receipts for the purpose of verifying Pro entitlements. RevenueCat's terms: https://www.revenuecat.com/terms

Article 9 — Intellectual Property

All content, features, design, and code of the App are owned by or licensed to the Provider and protected by copyright law. Users are granted a limited license to use the App for personal, non-commercial purposes only.

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
Advise active subscribers to cancel their subscriptions via Google Play to avoid further charges

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

Article 11 — Suspension and Termination

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

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

      💡 Protection for paid users: If access is terminated at the Provider's discretion, paid Pro users will either retain access for the remainder of their paid period or be guided through a refund process via Google Play.
    

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, including any disputes with tax authorities or third parties based on records generated by 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.

DISCLAIMER: DriveLedger is an independent app and is not affiliated with, endorsed by, or connected to the IRS or any government agency. Mileage rates are based on IRS standard mileage rates published at irs.gov. Verify current rates at irs.gov or with your local tax authority. This app does not provide tax advice — consult a qualified tax professional for guidance specific to your situation.

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