1. About these Terms
These Terms of Use ("Terms") govern your use of the Android application Moj Auto Dnevnik ("the App"). By installing, opening, or using the App, you agree to these Terms. If you do not agree, please do not install or use the App.
These Terms should be read together with the Moj Auto Dnevnik Privacy Policy, which describes how the App handles your data.
2. What the App is
Moj Auto Dnevnik is a personal vehicle logbook for Android that helps you track fuel and charging, services, tires, registration, insurance, vignettes, fines, and other vehicle-related expenses. It also provides a dashboard, analytics, reminders, and PDF/JSON exports.
The App is designed to work fully offline. All your data is stored locally on your device. The App does not use user accounts, does not sync to any server, and does not share your data with third parties.
The only network activity performed by the App is an optional refresh of official European Central Bank (ECB) daily reference exchange rates, used to convert expenses recorded in other currencies into your vehicle's primary currency. This is described in detail in the Privacy Policy.
3. Who can use the App
You may use the App if you are legally able to enter into a binding agreement in your country of residence. If you are a minor, you may only use the App with the involvement and consent of a parent or legal guardian.
The App is primarily intended for personal use. It may also be used for professional record-keeping where permitted by applicable law.
4. Your license to use the App
Subject to your compliance with these Terms, you are granted a personal, non-exclusive, non-transferable, revocable license to install and use the App on Android devices that you own or control.
You may not:
- copy, modify, translate, or create derivative works of the App, except as expressly permitted by law;
- reverse engineer, decompile, or disassemble the App, except to the extent that applicable law expressly permits such activity;
- rent, lease, sublicense, sell, or otherwise commercially distribute the App;
- remove or alter any copyright, trademark, or other proprietary notices;
- use the App in a way that violates applicable laws or the rights of others.
All rights not expressly granted to you are reserved by the publisher.
5. Your data and your responsibility
All data you enter — vehicles, fuel and charging entries, services, tires, registration, insurance, vignettes, fines, other expenses, notes, and settings — is stored locally on your device.
You are solely responsible for:
- the accuracy and completeness of the data you enter;
- backing up your data using the App's JSON export feature;
- protecting exported JSON backups, which may contain all of your application data and should be stored securely;
- keeping your device secure (screen lock, encryption, updates);
- any decisions you make based on the App's calculations, summaries, reminders, or exports.
If you uninstall the App, reset your device, or the device is lost, damaged, or replaced, your data may be permanently lost unless you have exported a backup. The publisher cannot recover data stored only on your device.
6. Reminders and calculations
The App provides reminders (for example, upcoming registration, insurance, vignette expiry, or tire changes) and calculations (for example, average fuel consumption, cost per kilometer, monthly and yearly totals, and currency conversion).
These reminders and calculations are provided for your convenience only. They are based on the data you enter and on rules and reference rates bundled with the App. They are not legal, financial, tax, safety, or technical advice.
You remain fully responsible for:
- meeting all legal obligations related to your vehicle (registration, mandatory inspections, insurance, tolls, vignettes, road tax, emissions, etc.);
- verifying important dates and amounts with official sources (authorities, insurers, service providers);
- vehicle safety and maintenance decisions.
Missing or incorrect reminders do not release you from any legal or contractual obligation.
7. Exchange rates
The App uses a layered approach to convert amounts entered in other currencies into your vehicle's primary currency:
- Manual exchange rates you enter for a specific record;
- Cached rates previously refreshed from the official European Central Bank (ECB) daily reference exchange rates;
- Static reference rates bundled with the App.
Exchange rates are provided for informational purposes only and may not match the rate used by your bank, card issuer, fuel station, or other payment provider. The App does not perform any financial transaction.
Refreshing rates is optional and requires an internet connection. When you refresh, only historical entries that used the previous cached rate are updated as designed; entries with a manual exchange rate remain unchanged.
8. PDF reports, JSON export, and ICS reminders
The App can generate:
- PDF reports (Service Book, Annual Report), localized to the currently selected application language;
- JSON backups containing your application data;
- ICS calendar files for selected reminders.
You are responsible for how you use these files, including whether and how you share them with third parties (for example, a mechanic, insurer, employer, or family member). Once you share a file, its contents are outside the App's control.
9. No warranty
To the maximum extent permitted by applicable law, the App is provided "as is" and "as available", without warranties of any kind, whether express, implied, or statutory, including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy, reliability, availability, or non-infringement.
The publisher does not warrant that:
- the App will be uninterrupted, error-free, or free of defects;
- calculations, reminders, or reports will be complete, accurate, or suitable for any specific purpose;
- exchange rates or bundled reference data will be current or accurate at any given moment;
- the App will be compatible with every Android device, version, or configuration.
Some jurisdictions do not allow the exclusion of certain warranties. In such jurisdictions, the exclusions above apply only to the extent permitted by law, and you may have additional rights that cannot be waived.
10. Limitation of liability
To the maximum extent permitted by applicable law, the publisher shall not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of data, loss of profits, loss of savings, loss of use, business interruption, or damage to your device or vehicle, arising out of or related to your use of, or inability to use, the App — even if the publisher has been advised of the possibility of such damages.
In particular, the publisher is not liable for:
- data loss caused by uninstallation, device reset, device loss or damage, or failure to create backups;
- decisions you make based on the App's reminders, calculations, or exports;
- missed legal, administrative, or financial deadlines;
- differences between exchange rates shown in the App and rates applied by third parties.
Where liability cannot be excluded under applicable law, it is limited to the maximum extent permitted by that law.
11. Third-party services and stores
The App is distributed through the Google Play Store and runs on Android devices. Your use of the store, the operating system, and your device is also subject to the terms of the relevant third parties (for example, Google and your device manufacturer). The publisher is not responsible for those third parties or their terms.
Refreshing exchange rates connects to an official European Central Bank (ECB) endpoint. That endpoint is operated by the ECB and is subject to its own terms and availability.
12. Updates and changes to the App
The publisher may release updates to the App from time to time. Updates may add, change, or remove features, fix defects, or adjust bundled reference data (such as static exchange rates). Some updates may be required to keep the App working correctly on newer Android versions.
Existing local user data remains on the device unless removed by the user or the operating system.
The publisher may also, at its discretion, discontinue the App or specific features. Where reasonably possible, users will be given advance notice through the store listing or in-app messaging.
13. Changes to these Terms
These Terms may be updated to reflect changes in the App, in applicable law, or in the publisher's contact details. The current version and its effective date will always be available within the App, in the store listing, and/or on this website.
Your continued use of the App after an updated version of the Terms becomes effective constitutes your acceptance of the updated Terms. If you do not agree with the updated Terms, please stop using the App and uninstall it.
14. Termination
You may stop using the App at any time by uninstalling it from your device. In most cases, uninstalling the App removes locally stored data unless you have exported a backup.
The publisher may suspend or terminate your license to use the App if you materially breach these Terms. Sections that by their nature should survive termination — including intellectual property, disclaimers, limitation of liability, and governing law — will continue to apply.
15. Governing law
These Terms are governed by the laws of the Republic of Serbia, without regard to conflict-of-law principles, and subject to any mandatory consumer protection laws of your country of residence that cannot be contractually waived.
