Terms of use

Last updated: 5 October 2026

1. Who provides the app

The quantumecusti app is provided by Ditta La Cibernetica di Luigi Conte, VAT IT04207270754, Via Rosmini 37, 73046 Matino (LE), Italy, info@lacibernetica.it. By using the app or the web version, or by creating an account, you accept these terms and the privacy policy.

2. What it does and what it costs

The app lets you record data about your vehicles (kilometres, miles or engine hours, fill-ups, expenses, deadlines, checks), calculates what they cost you and reminds you of deadlines and checks. You can use it without an account or create an optional account to sync data across devices, use it from the web version and share a vehicle with other people.

The app and the account are free, and the service is supported by advertising (section 4). If some features later become paid, for example an ad-free subscription, we will tell you first and you will never be charged without an explicit choice on your part.

3. Calculations, conversions and reminders

• Costs, consumption and averages are calculated only from the data you enter: if the data is incomplete or wrong, so are the results. They are estimates to guide you, not accounting or tax documents.
• Currency conversions use the European Central Bank reference rates of the day of the expense, and unit conversions (miles, gallons, consumption formats) are rounded: they are indicative and may differ from what your bank or fuel station applies.
• Warning lights, reminders and suggested maintenance intervals are generic help: they don't replace the instructions of your vehicle's manufacturer, your mechanic or official notices (for example about road tax, insurance or inspections). Meeting deadlines and keeping the vehicle safe remain your responsibility.
• To the extent permitted by law, we are not liable for fines, costs or damage due to a missed deadline, wrongly entered data, calculations based on that data or notifications not shown by the device.

4. Offers, advertising and affiliate links

• The app shows offers for our own products and from partner companies, always marked "Ad". Some links are affiliate links: if you buy after tapping them, we may earn a commission, at no extra cost to you.
• Products, services, prices, promotions, availability and conditions of offers are set by the partners, who are solely responsible for them. Prices and promotions shown in the app are indicative and may be changed by the partner: what is stated on its website at the time of purchase applies.
• If you buy from a partner, the contract is between you and the partner, under its terms and privacy policy: we are not a party to the contract and are not responsible for performance, warranties, deliveries or returns. The same applies to local businesses (garages, body shops, inspection centres and the like) appearing in offers for your area.
• Showing an offer doesn't mean we guarantee the partner or its products. We select partners carefully and remove offers that turn out to be misleading: if you see one, report it from the app (Settings, Report a problem).

5. Your data

Without an account the data you enter stays only on your device (see the privacy policy): we don't keep a copy and can't recover it if you lose your phone, uninstall the app or clear its data. Use the file backup to make a safety copy.

With an account, data is also saved on our server. We do our best to protect and preserve it, but we can't guarantee it will never be lost: we still recommend making a file backup from time to time.

6. Account

• To create an account you must be at least 14, or the higher age set in your country for using online services on your own, and provide a valid email. You are responsible for keeping your password confidential and for what happens with your account.
• You can delete the account at any time from the app or the web version: the account and server data are immediately and permanently deleted.
• We may suspend or close an account used against these terms or the law, after warning you where possible.

7. Shared vehicles

• The owner of a vehicle can invite other people as a collaborator (sees and edits everything except the vehicle details and sharing) or an employee (enters fill-ups, expenses and readings, and sees only what they entered).
• Only share a vehicle with people you trust: invitees see the data their role allows. The owner is responsible for whom they invite and for informing the people involved, for example employees, about the use of their data, as required by the laws of their country.
• What an invitee enters on a shared vehicle stays with the vehicle's owner, even if the invitee leaves the vehicle or deletes their account.

8. Proper use

Don't use the app unlawfully and don't try to modify, decompile or circumvent its protections, except where the law allows it. Don't use the app while driving, don't enter other people's data without the right to do so and don't try to access other accounts' data. You may not use the app if the laws of your country forbid it, including sanctions and export laws.

9. Availability and changes

The app is provided free of charge, as is and as available. We work to make it run well, but we can't guarantee it will always be error-free, compatible with every device or fit for a particular purpose. The server and web version may have interruptions, for example for maintenance. We may update the app, change its features or stop distributing it; if we had to close the account service, we would give you reasonable notice so you can save your data.

10. Limitation of liability

To the maximum extent permitted by applicable law, we are not liable for indirect or consequential damage, lost profits, loss of data or damage arising from the use of or inability to use the app, from partner offers or from external websites. This limitation does not apply where the law doesn't allow it, in particular for wilful misconduct or gross negligence, for personal injury and for the rights granted to you by the consumer protection laws of your country that cannot be excluded.

11. App downloaded from the App Store or Google Play

• These terms are between you and us, not Apple or Google. The store you downloaded the app from is not responsible for the app or its content and has no support or maintenance obligations: send any request, complaint or claim (including those about third-party rights or legal compliance) to us.
• If the app fails to conform to a warranty required by law, you may ask Apple to refund the price paid, if any; beyond that, to the extent permitted by law, Apple has no other warranty obligation for the app.
• Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you. The usage rules of the store you downloaded the app from also apply.

12. Changes to these terms

If we change these terms we publish the new version here with its update date; significant changes will be shown to you in the app. If you don't agree, you can stop using the app and delete your account at any time.

13. Governing law and disputes

These terms are governed by Italian law. If you are a consumer, you keep the mandatory protections of the law of the country where you live and, where the law provides for it, the jurisdiction of the courts of your place of residence. Before going to court please write to us: we will try to solve the problem together. If any clause of these terms turns out to be invalid, the others remain in force.
