Legal

Terms of Use

Version 1.0 — effective June 2, 2026. Applies to all RunRiva mobile apps (including U.S. Presidents Quiz).

1. Who provides the apps

The apps are provided by Maciej Dzierżek, sole proprietor (CEIDG), ul. Cieszyńska 1a/57, 02-716 Warsaw, Poland · NIP PL7411885009 · REGON 280016640 (“Studio”, “we”). By downloading or using an app you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the app.

2. Changes to these Terms

We may update these Terms for valid reasons (legal, technical, new features). For material changes we give reasonable advance notice in-app (at least 30 days where practicable); you may object by ceasing to use the apps before the changes take effect. The current version is always published here.

3. Eligibility

The apps are intended for users aged 13 and over (or 16 where local law, including in Poland and parts of the EEA, requires parental consent for data processing). If you are under the age of majority, you confirm a parent or guardian permits your use. The apps are for natural persons for personal use.

4. Your account & anonymous play

You can play anonymously. You may optionally secure your progress with an email-verified account; one account is for one person and is non-transferable. You are responsible for activity under your account. You can delete it at any time — see Delete your account.

5. Licence to use the apps

We grant you a personal, non-exclusive, non-transferable, limited licence to use the apps for your own non-commercial entertainment. We may revoke this licence for breach of these Terms or where required by law — not arbitrarily, and without prejudice to paid entitlements you already hold. You may not copy, modify, reverse-engineer, scrape, resell or redistribute the apps except as mandatory law allows. On Apple devices, this licence is at least as restrictive as Apple’s standard Licensed Application End User License Agreement.

6. Fair play & acceptable use

Don’t cheat, automate or use bots, manipulate scores, reverse-engineer or scrape the app, use abusive display names or content, or attempt to disrupt the service or other players. We may withhold scores or rewards, reset leaderboard entries, or suspend or terminate accounts that breach these Terms.

7. In-app purchases

Some features are available via in-app purchases (e.g. removing ads, a Supporter subscription, game currency packs — for example Votes — and a cross-app Bundle Pass). Purchases are sold and processed by the Apple App Store or Google Play under their terms; we do not receive or store your payment-card data. Prices and currency are shown before purchase. Subscriptions, if offered, renew per the store’s rules and are managed or cancelled in your store account. Refunds are handled by the relevant store under its policy. Entitlements are managed via RevenueCat.

8. Right of withdrawal (digital content)

Purchases are digital content delivered immediately. By completing a purchase you expressly request immediate performance and acknowledge that, once delivery begins, you lose the statutory 14-day right of withdrawal for that purchase under EU/Polish consumer law. This does not affect any other mandatory consumer rights, or refund options offered by Apple/Google.

9. Virtual items

Hints, in-game currency and similar items are licensed for in-app use, not sold. They have no monetary value, do not correspond to any real-world money or credit, and cannot be transferred, traded, sold, redeemed or cashed out. We may adjust the game economy, and unused items are forfeited without compensation if you delete your account. If we permanently discontinue an app, we will give reasonable advance notice and handle any outstanding paid entitlements in line with mandatory consumer law and the relevant store’s policies.

10. Ads

Free versions are supported by ads (Google AdMob), including optional rewarded ads you choose to watch. Ad personalization depends on your consent and device settings (see the Privacy Policy). We are not responsible for the content of third-party ads. You can remove ads via an in-app purchase.

11. Display names, leaderboards & user content

If you choose a display name or use leaderboards, friends or challenges, you grant us a limited, non-exclusive licence to display that content within the apps (e.g. on leaderboards and in challenges you take part in) for the purpose of providing those features. Keep names and content lawful and inoffensive; we may remove content or names that breach these Terms.

12. Content & accuracy

Trivia questions are compiled from open, source-attributed datasets and calibrated by our engine, QuizBase — see Sources & licenses. Despite our care, questions and answers are provided for entertainment only and may be incomplete, outdated or contain errors; we make no warranty as to their accuracy, reliability or completeness, and they are not professional, educational or factual advice. We are not affiliated with, endorsed or sponsored by any government body, organisation, brand or person referenced in the questions.

13. Intellectual property

The apps, brand and original design are ours or our licensors’. We do not claim ownership of the underlying trivia facts or of the third-party datasets, which remain under their respective open licences with attribution (see Sources & licenses).

14. Disclaimers

To the fullest extent permitted by law, the apps are provided “as is” and “as available”, without warranties of any kind. This does not exclude or limit any warranty or right that cannot be excluded under applicable mandatory law.

15. Limitation of liability

To the extent permitted by law, we are not liable for indirect, incidental or consequential damages, lost profits, or loss of progress or virtual items, and our total liability is limited to the amount you paid us (if any) in the 12 months before the event. Nothing in these Terms excludes or limits our liability for: death or personal injury caused by negligence; fraud or fraudulent misrepresentation; gross negligence or wilful misconduct; product liability; or any liability that cannot be excluded or limited under Polish or EU law. If you are a consumer, you keep all mandatory statutory rights (including conformity/“rękojmia” and complaint rights), which these Terms do not affect.

16. Consumer rights & complaints

If you are a consumer, you may file a complaint (“reklamacja”) by emailing maciej.dzierzek@gmail.com; we aim to respond within 14 days. If unresolved, EU consumers may seek out-of-court resolution through their local consumer-protection body — in Poland, a permanent consumer arbitration court (stały polubowny sąd konsumencki) at the Trade Inspection (Inspekcja Handlowa) or a municipal/district consumer ombudsman (rzecznik konsumentów). (The EU Online Dispute Resolution platform was discontinued in 2025.)

17. Suspension & termination

You may stop using the apps and delete your account at any time. We may suspend or terminate access for breach of these Terms or where required by law. Sections that by their nature should survive (e.g. §§ 9, 12–16, 18–19) survive termination.

18. Apple devices

For apps obtained from the Apple App Store: these Terms are between you and the Studio, not Apple, and Apple is not responsible for the apps or support. However, Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. Apple’s standard App Store terms also apply.

19. Governing law & disputes

These Terms are governed by Polish law. If you are a consumer, this does not deprive you of the mandatory protections of the law of your country of habitual residence, and you may bring proceedings there. We do not impose binding arbitration. We aim to resolve issues amicably first — please contact us.
