Terms of Use

Last updated November 11, 2026

1. About these Terms

These Terms of Use ("Terms") are a legally binding agreement between you and Nerdish OÜ ("Nerdish", "we", "us", "our") governing your use of the following (together, the "Services"):

  • the website www.nerdish.io;
  • the website www.virtuosomusic.app;
  • the mobile applications Nerdish, Factorium: Today in History and Virtuoso: Classical Music Guide (the "Apps").

Nerdish OÜ is a company registered in Estonia, registry code 16116064, with its registered office at Ahtri tn 12, Kesklinna linnaosa, Tallinn, Harju maakond, 10151, Estonia. Email: info@nerdish.io.

By accessing or using the Services, you agree to these Terms. If you do not agree, do not use the Services.

Nothing in these Terms excludes or limits your statutory rights as a consumer, including your right to receive digital content and services that conform to the contract and any right of withdrawal under EU law.

These Terms are supplemented by our Privacy Policy and, for purchases made in the Apps, by the terms of the App Store or Google Play.

2. Changes to these Terms

We may update these Terms, for example to reflect changes to the Services or to the law. We will notify you of material changes at least 30 days before they take effect, in the Apps or on our websites. The "Last updated" date above shows when these Terms were last changed.

If you do not agree with the updated Terms, you may stop using the Services and cancel any subscription before the changes take effect. If you continue to use the Services after that date, the updated Terms apply.

3. Free access and advertising

Parts of the Services are available free of charge. The free version of the Apps may display advertising, including advertising from third parties, and may limit access to some content or features.

We may change what is included in the free version. Such changes do not affect a subscription you have already paid for.

4. Subscriptions and payments

Some Apps offer paid subscriptions that remove advertising and unlock additional features. The plans, prices and included features are shown in the App before purchase.

Purchase. Subscriptions are purchased and billed through the App Store or Google Play (the "App Distributor"). Payment is charged to your App Distributor account, and the App Distributor's terms apply to the purchase.

Free trials. Some plans include a free trial. Unless you cancel at least 24 hours before the trial ends, the subscription starts automatically and you are charged for the plan you selected.

Automatic renewal. Subscriptions renew automatically at the end of each billing period unless you cancel at least 24 hours before the period ends.

Cancellation. You can cancel at any time in your App Distributor account settings. Deleting the App does not cancel a subscription. After cancellation, you keep access until the end of the current billing period.

Price changes. Subscription prices may change. The App Distributor notifies you of price changes and, where its rules require, asks for your consent before a higher price applies.

Refunds. Refunds are handled by the App Distributor under its policies. We cannot issue refunds for purchases made through the App Store or Google Play.

5. Intellectual property

The Services and all their content, including articles, text, audio, video, images, graphics, software, databases and design (the "Content"), as well as our names, trademarks and logos (the "Marks"), are owned by or licensed to Nerdish. They are protected by copyright, trademark and other intellectual property laws and international conventions.

We grant you a limited, personal, non-exclusive, non-transferable licence to access and use the Services and the Content for your personal, non-commercial use, in accordance with these Terms.

Except as expressly permitted in these Terms or with our prior written permission, you may not copy, reproduce, republish, publicly display, translate, distribute, sell or otherwise exploit any part of the Services, the Content or the Marks.

We reserve all rights not expressly granted to you.

6. Acceptable use

You agree to use the Services only for their intended purpose and in compliance with these Terms and applicable law. In particular, you agree not to:

  • use the Services for any illegal purpose, or for any commercial purpose without our written permission;
  • access the Services or collect Content by automated means, including bots, scrapers, data mining or similar tools, other than standard search engine or browser use;
  • circumvent security features or restrictions on access to paid content or features;
  • upload malicious code or interfere with the operation of the Services or the networks connected to them;
  • harass, abuse or harm other people, including our employees and contractors;
  • use the Services or the Content to build a competing product or service.

7. Mobile application licence

Licence. We grant you a revocable, non-exclusive, non-transferable, limited right to install and use the Apps on devices you own or control, in accordance with these Terms and the usage rules of the App Distributor. You may not:

  1. except as permitted by applicable law, decompile, reverse engineer, disassemble, attempt to derive the source code of, or decrypt the Apps;
  2. modify, adapt, translate or create derivative works from the Apps;
  3. host the Apps or make them available over a network for use by others.

8. Feedback

If you send us questions, comments, suggestions, ideas or other feedback about the Services ("Feedback"), you grant us a free, worldwide, non-exclusive, perpetual licence to use that Feedback for any lawful purpose, without compensation to you. You confirm that you have the right to share the Feedback with us.

9. Educational content

The Content is provided for general educational and informational purposes. It is not medical, legal, financial or other professional advice and should not be relied on as such. We check the Content editorially, but it may contain errors or become outdated.

10. Privacy

Our Privacy Policy describes how we process personal data when you use the Services.

11. Changes to and availability of the Services

We develop the Services continuously and may change their content and features, for example to add or remove topics, improve functionality, or comply with the law. If a change to a paid subscription materially reduces what you paid for, we will inform you in advance, and you may cancel your subscription within 30 days of being informed.

During an active subscription, we provide the updates needed to keep the Apps working as described.

We cannot guarantee that the Services will be available at all times. Hardware, software or other problems and maintenance may cause interruptions, delays or errors.

If we decide to discontinue a paid App or subscription, we will inform you in advance. A refund for the unused part of a prepaid subscription period can be requested through the App Distributor.

12. Suspension and termination

These Terms apply for as long as you use the Services.

You may stop using the Services at any time by deleting the Apps. To end a paid subscription, cancel it in your App Distributor account settings (see section 4).

We may suspend or restrict your access to the Services, including by blocking certain IP addresses, if you materially breach these Terms or applicable law. Where reasonable, we will inform you of the reason. We may also take appropriate legal action, including seeking civil and injunctive remedies and reporting unlawful activity to law enforcement authorities.

13. Disclaimers

We provide the Services with reasonable care, but we do not promise that they will be uninterrupted, error-free or meet every individual expectation.

To the extent permitted by law, we are not responsible for:

  • the content of third-party websites linked from the Services;
  • products or services advertised by third parties in the Services, or any transaction between you and such third parties;
  • interruptions or cessation of transmission to or from the Services;
  • viruses or other harmful code transmitted to or through the Services by a third party.

14. Limitation of liability

To the extent permitted by law, Nerdish and its directors, employees and contractors are not liable for indirect or consequential damages, including lost profit, lost revenue or loss of data, arising from your use of the Services.

To the extent permitted by law, our total liability to you for any claim relating to the Services is limited to the amount you paid for the Services during the three months before the claim arose.

These limitations do not apply to liability for intentional breach or gross negligence, for death or personal injury, or to any other liability that cannot be limited or excluded under applicable law.

15. Governing law and disputes

These Terms are governed by the laws of Estonia. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

If you are a consumer habitually resident in the EU, you also keep the protection of the mandatory provisions of the law of your country of residence. You may bring a claim relating to these Terms either in the courts of Estonia (Harju County Court) or in the courts of the EU country where you live.

If you have a complaint, please contact us first at info@nerdish.io, and we will try to resolve it.

If we cannot resolve a dispute, consumers may also contact the Estonian Consumer Disputes Committee (Tarbijavaidluste komisjon), which handles consumer disputes out of court and free of charge: ttja.ee.

16. California users and residents

If a complaint is not satisfactorily resolved with us, you can contact the Complaint Assistance Unit of the Division of Consumer Services of the California Department of Consumer Affairs in writing at 1625 North Market Blvd., Suite N 112, Sacramento, California 95834, or by telephone at (800) 952-5210 or (916) 445-1254.
