Transport-Yak Terms of Use

Effective date: 2026-04-17

§ 1. General provisions

These Terms of Use (the "Terms") set out the rules for using the "Transport-Yak" mobile application (the "App"), made available via the Google Play Store for Android devices (and, in the future, via the App Store for iOS devices).
The App is published and administered by Hojka, a natural person, correspondence address: Poland, e-mail: [email protected] (the "Operator").
By downloading, installing or using the App, the user ("User") accepts these Terms and the Privacy Policy.
These Terms are governed by the laws of the Republic of Poland. The English version is provided for convenience only; in case of discrepancy, the Polish version prevails.

§ 2. Definitions

For the purposes of these Terms:

User — a natural person at least 13 years of age who has downloaded the App onto a mobile device.
Service — the functionality provided by the App, in particular: a) presentation of information about temporary truck traffic restrictions in European countries, b) a truck axle-load calculator.
Ban Data — information about temporary restrictions on heavy-goods vehicle traffic displayed in the App.
Free Version — the free-of-charge version of the App, in which the User accesses the Service with displayed advertisements and with the feature limitations described in § 5.
Premium Subscription (or "Premium") — the paid subscription in a monthly or yearly plan, removing advertisements and feature limitations. Details in § 5.
Introductory Period — the first 14 days after the App is installed, during which the App operates in a mode equivalent to the Premium Version, free of charge and without any action required from the User.
Store Operator — Google LLC / Google Ireland Ltd. (for the Android version) or Apple Distribution International Ltd. (for the iOS version), acting as the seller of the subscription for consumer-law purposes.

§ 3. Nature of the Service

The App is provided for informational and illustrative purposes only.
Ban Data displayed in the App is aggregated from publicly available sources and may not be fully current, complete or consistent with the legal status in force in a given country.
The axle-load calculator uses a simplified physical model (two-sided lever) and does not account for all real-world factors (vehicle dynamics, suspension, vertical load distribution).
The User acknowledges that: a) actual traffic bans, time restrictions and permissible axle loads may differ from the data presented in the App, b) before taking any decision affecting the safety, legality or costs of a journey (in particular the choice of route or vehicle loading), the User is obliged to verify the information with official sources — ministries of transport, road authorities, law-enforcement bodies of the destination countries.
The App does not replace professional transport, legal or technical advice.

§ 4. Conditions of use

The App is offered under a freemium model: a) Free Version — free of charge, with displayed advertisements (see § 6), b) Premium Subscription — paid, without advertisements and without feature limitations (see § 5).
Regardless of the chosen version, the User is granted an Introductory Period — the first 14 days after installation, during which the App operates in a mode equivalent to Premium. After the 14 days elapse, or after the User exhausts the limit of 10 cargo-section additions in the axle calculator (whichever comes first), the App switches to the Free Version mode, unless the User has purchased a Premium Subscription.
To use the App, the User must have: a) a mobile device running Android 7.0 (API 24) or later, or iOS in a corresponding minimum version, b) periodic internet access to refresh the Ban Data and to verify Premium Subscription status.
The App also operates in offline mode using locally cached data. The currency of such data depends on the time of the last synchronisation.
The User undertakes to use the App in accordance with its intended purpose, applicable law and good practice.
It is prohibited to: a) decompile, reverse-engineer or modify the code of the App (except where permitted by law), b) perform automated or mass retrieval of data from the Operator's servers, c) attempt to circumvent technical safeguards, in particular mechanisms verifying Premium Subscription status or the section-addition counter, d) use the App for unlawful purposes.

§ 5. Premium Subscription

The Operator offers a paid Premium Subscription in two variants: a) Monthly Premium — EUR 3 per month, renewed automatically every month, b) Annual Premium — EUR 15 per year (approximately EUR 1.25 per month), renewed automatically every 12 months.
Prices are shown including VAT; the final price in the User's local currency may differ due to exchange rates and local taxes — this price is shown to the User in the App before finalising the purchase, in the purchase panel provided by the Store Operator.
The Premium Subscription entitles the User to: a) full removal of advertisements (the banner in the "Bans" section and the rewarded ads in the axle calculator), b) unlimited cargo-section additions in the axle calculator, c) supporting the App's development.
The seller of the Premium Subscription for consumer-law purposes is the Store Operator (Google LLC / Google Ireland Ltd. for Android or Apple Distribution International Ltd. for iOS). The Operator is solely a digital content supplier.
Purchases are made through Google Play Billing or Apple App Store Billing. The Operator does not receive or store the User's payment-card or bank-account data.
The subscription renews automatically unless the User cancels it at least 24 hours before the next renewal date. After cancellation, Premium benefits remain available until the end of the paid billing period.
Cancellation takes place solely via the Store Operator's panel: a) Android — Google Play → profile → Subscriptions → Transport-Yak → Cancel subscription, b) iOS — Settings → [your name] → Subscriptions → Transport-Yak → Cancel subscription.
Right of withdrawal (consumer): a) A User who qualifies as a consumer (or a natural person running a business benefiting from consumer-law protection) has the right to withdraw from the purchase of the Premium Subscription within 14 days without giving reasons, pursuant to Art. 27 of the Polish Consumer Rights Act of 30 May 2014. b) Pursuant to Art. 38 item 13 of the Consumer Rights Act, the right of withdrawal does not apply if the User has given explicit consent to the commencement of the Premium Service before the withdrawal period expires and has been informed of the loss of the right of withdrawal. The Google Play / App Store purchase panel contains such declarations, and tapping the purchase button is equivalent to giving that consent and acknowledging the loss of the right of withdrawal. c) In practice — once the User has first used the Premium Service (e.g. the App disables ads upon subscription activation), the User loses the right of withdrawal. d) Refund requests should be directed to the Store Operator:
- Google Play: https://support.google.com/googleplay/answer/2479637,
- Apple App Store: https://reportaproblem.apple.com.
Price changes: a) The Operator may change the price of the Premium Subscription at any time. The new price applies only from the next renewal. b) The User will be notified of price changes via the Store Operator and/or the App at least 30 days before the new price takes effect. c) Failure to cancel the Subscription within that period constitutes acceptance of the new price.
Restore purchases — a User who has uninstalled and reinstalled the App may restore an active Premium Subscription by tapping "Restore purchases" on the subscription screen, provided the User is logged into the same Store Operator account (Google Play / App Store) from which the purchase was made.

§ 6. Advertising in the Free Version

The Free Version of the App displays advertisements in the following formats: a) Banner advertisement — shown in the "Bans" section below the date-selection bar, b) Rewarded ads — short video ads displayed on the User's request (tapping "Add section" in the axle calculator after exceeding the free limit); watching the ad to completion unlocks one cargo-section addition, c) In-app Premium Subscription promotions — shown on rotation in place of external ads (every fifth ad, or every ad when there is no internet connection or when the ad network fails to deliver an ad).
External advertisements are served by Google AdMob. The Operator has no control over the content, format or timing of these ads — selection is automated on AdMob's side based on the ad-account configuration and (with the User's consent) the User's interest profile.
The Operator is not liable for the content of third-party advertisements. A User who considers a displayed ad to be unlawful or inappropriate may: a) report it directly to Google (https://support.google.com/google-ads/troubleshooter/4578507), b) report it to the Operator at [email protected] — the Operator will forward the report to AdMob and, where possible, block the advertiser in question.
In the European Union, before the first ad is displayed, the User will see a consent dialogue (Google Consent Mode v2 / IAB TCF) allowing a choice between: a) personalised advertising (requiring consent for the processing of the Advertising ID and behavioural signals for advertising purposes), b) non-personalised advertising (no interest-based profiling; based solely on context and approximate geographical location).
The User may at any time: a) withdraw consent for personalised advertising in the operating-system settings (Android: Privacy → Ads → Limit ad tracking; iOS: Settings → Privacy → Apple Advertising), b) reset the Advertising ID (AAID / IDFA), c) completely remove advertisements by purchasing the Premium Subscription (§ 5).
Detailed information about data processing in connection with advertising is provided in § 3.3 of the Privacy Policy.

§ 7. Intellectual property rights

Economic copyright to the App, including the source code, graphics, text, layout and functionality, belongs to the Operator.
Map data used in the App comes from OpenFreeMap and is made available under the Open Database License (ODbL) by the OpenStreetMap Contributors community (https://www.openstreetmap.org/copyright).
The User is granted a non-exclusive, non-transferable, royalty-free licence to use the App for personal use or as an auxiliary tool in connection with their business activity. The Premium Subscription does not alter the scope of this licence — it only expands the App's functionality.

§ 8. Limitation of liability

To the maximum extent permitted by law, the Operator shall not be liable for: a) any material or non-material damage (including lost profits, administrative fines, costs of unrealised transports) arising from decisions taken by the User based on data presented in the App, b) the currency, completeness or factual accuracy of the Ban Data, c) temporary or permanent unavailability of the App, technical errors, loss of the User's local data, d) damage arising from the User's misuse of the App, in particular from disregarding official information sources, e) acts or omissions of third parties whose services are used by the App (map providers, network infrastructure, ad networks, store operators, subscription-management providers), f) the content of advertisements displayed in the Free Version (see § 6.3).
The limitations of liability set out in paragraph 1 shall not apply to: a) damage caused intentionally or through gross negligence of the Operator, b) claims the limitation or exclusion of which is inadmissible under mandatory provisions of law, in particular consumer protection provisions.

§ 9. Complaints

The User may submit complaints concerning the operation of the App to the e-mail address: [email protected].
A complaint should include: a) a description of the problem, b) the date and time of occurrence, c) the device model and operating-system version, d) the App version.
The Operator shall process complaints within 30 days of receipt and respond to the e-mail address from which the complaint was sent.
Complaints concerning payments for the Premium Subscription (refunds, duplicate charges, unauthorised transactions) should be directed to the Store Operator (Google Play / Apple App Store), which is the seller of the subscription. The Operator has no technical ability to issue refunds.

§ 10. Consumer rights

The provisions of these Terms do not limit or exclude consumer rights arising from: a) the Polish Consumer Rights Act of 30 May 2014, b) the Polish Civil Code of 23 April 1964, c) Regulation (EU) 2016/679 (GDPR).
The specific rules on the right of withdrawal from the Premium Subscription are set out in § 5.8.
A consumer may use out-of-court methods of dispute resolution, in particular via the EU Online Dispute Resolution platform: https://ec.europa.eu/consumers/odr.

§ 11. Changes to the Terms

The Operator reserves the right to amend these Terms for important reasons, in particular: a) changes in applicable law, b) changes in the App's functionality (including introduction of new subscription plans or changes to the advertising model), c) changes in cooperation with third-party providers.
The User will be notified of changes within the App at least 14 days before they take effect.
A User who does not accept the new version of the Terms should discontinue use of the App and — in the case of an active Premium Subscription — cancel it with the Store Operator pursuant to § 5.7.

§ 12. Final provisions

The governing law of these Terms is Polish law.
Matters not regulated herein shall be governed by, in particular: a) the Polish Civil Code, b) the Act of 18 July 2002 on Providing Services by Electronic Means, c) the Consumer Rights Act of 30 May 2014.
Disputes arising from the use of the App shall be resolved by the court having jurisdiction under Polish law. A consumer may request that the dispute be resolved by the court having jurisdiction over their place of residence.
If any provision of these Terms is found invalid or unenforceable, this shall not affect the validity of the remaining provisions.
These Terms enter into force on 2026-04-17.
