Terms of Use

Last updated: October 17, 2026

The rules for using Kilunavo. The German version is legally binding.

1. Scope and provider

These terms apply to the use of the Kilunavo app for iPhone and the website kilunavo.donner.io. The provider is Dennis Donner, Eduard-v-Winterstein-Straße 11, 14480 Potsdam, Germany (app-support@donner.io). The website is hosted by WebhostOne. This English version is a translation; the German version is legally binding.

2. The app

Kilunavo is a mileage log for iPhone: you record business, private and commute trips by hand or with automatic tracking, assign them to vehicles, see routes on the map and create PDF or CSV reports. Kilunavo works without a user account.

3. Your data and backups

Your logbook is stored only on your device; I keep no copy. The app’s database is excluded from iCloud and computer backups. You are responsible for your entries and for keeping copies, for example by exporting reports regularly. If you delete the app or lose or reset your device, I cannot restore your data.

4. Distances, routes and reports

Distances, routes and durations come from your entries, from the location data of your device or from route calculations by Apple. GPS reception, iOS background limits and other conditions can make recorded routes incomplete or inaccurate, and automatic tracking can miss journeys. Please check your trips and correct them where needed.

Kilunavo is not certified as a tax-compliant logbook. Reports are a summary of your entries, not proof for tax, accounting or legal purposes. Check with your tax adviser whether they meet the requirements that apply to you.

5. Safety on the road

Do not operate the app while driving. Enter or edit trips only when you are parked safely, or let a passenger do it. Automatic tracking runs in the background and needs no interaction while you drive. Traffic rules always take precedence.

6. Purchases

Some features, such as automatic tracking, additional vehicles and reports, are offered as in-app purchases, including auto-renewing subscriptions. Without a purchase you can use one vehicle; data you have already entered stays readable at any time. Purchases are made through the Apple App Store and are subject to its terms. Payment, billing, renewal, cancellation and refunds — including any statutory right of withdrawal — are handled by Apple. The current offer and its terms are shown in the app and the App Store before you buy.

  • Cancel: in your Apple ID settings under “Subscriptions”, at the latest 24 hours before the end of the current period. Deleting the app does not cancel a subscription.
  • Refunds: via Apple (reportaproblem.apple.com).
  • Restore: use “Restore purchases” in the app with the same Apple ID.

7. Availability and changes

I develop Kilunavo continuously and may change, add or remove features, as long as this is reasonable for you and features you have bought remain available for the period you paid for. Services of third parties (for example maps and address search by Apple) may be unavailable at times. I aim for high availability but cannot guarantee uninterrupted operation.

8. Rights to the app

The app, its design and its content are protected by copyright. You receive a simple, non-transferable right to use the app within the App Store’s terms. Your statutory rights, in particular under §§ 69d and 69e of the German Copyright Act (UrhG), remain unaffected.

9. Liability

I am liable without limitation for intent and gross negligence, for injury to life, body or health, under the German Product Liability Act and where I have given a guarantee. For slight negligence I am liable only for breach of an essential contractual obligation, that is an obligation whose fulfilment makes proper performance possible in the first place and on whose fulfilment you may regularly rely; in that case liability is limited to the typical, foreseeable damage. Otherwise liability is excluded. These rules also apply to my representatives and agents. For features provided without payment, the statutory liability privileges apply.

10. Ending use

You can stop using Kilunavo at any time by deleting the app. Subscriptions must be cancelled separately (see “Purchases”).

11. Apple

These terms are an agreement between you and me as the provider, not with Apple. Apple is not responsible for the app, its content, maintenance or support. Apple’s Licensed Application End User License Agreement also applies; Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you. If the app does not conform to an applicable warranty, you may notify Apple, and Apple may refund the purchase amount; Apple has no further warranty obligation. I, not Apple, am responsible for handling claims relating to the app, including product liability, legal compliance and intellectual property claims.

12. Applicable law

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, this choice of law does not deprive you of the protection of mandatory provisions of the law of the country in which you habitually reside. I am neither obliged nor willing to participate in dispute-resolution proceedings before a consumer arbitration board.

13. Changes to these terms

I may update these terms if the app, the law or the App Store rules change. The current version is always available on this page; the date at the top shows when it was last changed. I will point out changes that affect you significantly in the app or on this page in good time.

14. Contact
