Terms of Service

Effective: May 24, 2026

These Terms of Service ("Terms") govern your use of Tonika — a music practice companion developed and operated by Brudne Brzmienie ("we," "us," or "our"), available as a web application and iOS app (the "Service").

By creating an account or using the Service, you agree to these Terms. If you do not agree, please do not use the Service.

1. Eligibility

You must be at least 13 years of age to use the Service. If you are between 13 and 18 (or the age of majority in your jurisdiction), you must have the consent of a parent or legal guardian. By using the Service, you represent that you meet these requirements.

2. The Service

Tonika is a music practice companion that provides real-time pitch detection, scale exercises, ear training, and progress tracking. It is designed to support your practice routine, starting with guitar and expanding to other instruments.

Please note:

  • Tonika is not a substitute for professional music instruction. It is a supplementary practice tool.
  • The accuracy of pitch detection depends on your microphone quality, ambient noise levels, and playing environment. Results may vary.
  • We continuously improve the Service and may add, modify, or remove features at any time.

3. Accounts

To access certain features, you must create an account using a valid email address. You may also sign in through Apple Sign In or Google Sign In.

  • You may create only one account per person
  • You are responsible for maintaining the security of your login credentials
  • You must notify us promptly at privacy@playtonika.com if you suspect unauthorized access to your account
  • We reserve the right to suspend or terminate accounts that violate these Terms

4. Subscriptions and Payments

Tonika operates on a freemium model. Core features are available for free. Premium features require a paid subscription.

4.1 Apple App Store Subscriptions

Subscriptions purchased through the iOS app are processed as auto-renewable in-app purchases through the Apple App Store. Apple handles all billing, refunds, and cancellation. Important details:

  • Your subscription automatically renews unless you cancel at least 24 hours before the end of the current billing period
  • To cancel, manage your subscription in your Apple ID settings (Settings > Apple ID > Subscriptions)
  • Refund requests must be directed to Apple, as they process all payments
  • If we change subscription prices, existing subscribers retain their current rate until the next renewal after the change takes effect

5. Your Data

Your practice data belongs to you. This includes practice records, XP, streaks, mastery scores, and saved session templates.

  • You can export your data at any time from the app's Settings page in a machine-readable format (JSON)
  • You can delete your account and all associated data through the app or by emailing privacy@playtonika.com
  • For full details on how we collect, use, and protect your data, see our Privacy Policy

6. Intellectual Property

The Service — including its design, code, graphics, audio, and branding — is owned by Brudne Brzmienie and protected by applicable intellectual property laws.

  • We grant you a limited, non-exclusive, non-transferable, revocable license to use the Service for personal, non-commercial purposes
  • Music theory concepts (scales, intervals, chords) are not proprietary — our specific implementation and presentation of them is
  • This license does not include the right to sublicense or distribute the Service

7. Acceptable Use

When using the Service, you agree not to:

  • Reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code of the Service
  • Use the Service for any commercial purpose without our prior written permission
  • Interfere with or disrupt the Service's infrastructure, servers, or networks

  • Use automated tools, bots, or scrapers to interact with the Service
  • Upload or transmit malicious code, viruses, or any harmful content
  • Impersonate another person or misrepresent your identity

8. Audio Safety

When using headphones with the Service — particularly during ear training exercises with reference tones — please exercise caution with volume levels. Prolonged exposure to high volume can damage your hearing. We are not responsible for hearing damage resulting from use of the Service at excessive volume levels.

9. Disclaimers

The Service is provided "as is" and "as available" without warranties of any kind, either express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement.

Specifically, we do not warrant that:

  • Pitch detection will be accurate in all environments or with all equipment
  • The Service will be uninterrupted, error-free, or secure
  • Using the Service will result in measurable musical improvement
  • All content will be free from errors

Nothing in these Terms excludes or limits rights that cannot be excluded or limited under applicable law, including EU consumer protection laws.

10. Limitation of Liability

To the maximum extent permitted by applicable law, the total liability of Brudne Brzmienie arising out of or in connection with the Service is limited to the greater of:

  • The amount you paid to us for the Service in the 12 months preceding the claim, or
  • €50 (fifty euros)

We are not liable for any indirect, incidental, special, consequential, or punitive damages, including loss of data, revenue, or profits.

This limitation does not apply where prohibited by law. If you are a consumer in the European Union, you retain all rights granted by mandatory consumer protection legislation in your country of residence.

11. Governing Law and Dispute Resolution

These Terms are governed by the laws of Poland, without regard to its conflict of law provisions.

If you are a consumer in the European Union, you retain the benefit of mandatory provisions of the law of your country of residence, and you may bring legal proceedings in the courts of your country of residence.

For online dispute resolution, you may also use the EU Online Dispute Resolution platform.

12. Changes to These Terms

We may update these Terms from time to time. When we do, we will revise the "Effective" date at the top of this page. For material changes, we will notify you through the app. Your continued use of the Service after changes take effect constitutes acceptance of the revised Terms.

13. Termination

Either party may terminate this agreement at any time:

  • You may stop using the Service and delete your account at any time
  • We may suspend or terminate your access if you violate these Terms, with notice where practicable

Before deleting your account, we recommend exporting your practice data from the Settings page. Upon account deletion, your data is permanently removed from our servers.

  • Severability — If any provision of these Terms is found unenforceable, the remaining provisions remain in full effect
  • No waiver — Our failure to enforce any right or provision does not constitute a waiver of that right or provision
