Terms of Use

Applies to the ChordPractice mobile app (the “Wren” practice app) for iOS & Android.
Effective date: June 23, 2026  ·  Last updated: June 23, 2026

These Terms of Use (“Terms”) are an agreement between you and Sammy Eang (“we”, “us”, or “our”) governing your use of the ChordPractice mobile application and any related services (the “App”). By downloading, installing, or using the App, you agree to these Terms. If you do not agree, do not use the App.

1. The App and your license

The App is a tool for practicing chords and progressions on piano. Subject to these Terms, we grant you a limited, personal, non-exclusive, non-transferable, revocable license to download and use one copy of the App on devices you own or control, for your own non-commercial use, in accordance with the usage rules of the app store you obtained it from.

This is a license, not a sale. We and our licensors retain all rights, title, and interest in the App that are not expressly granted to you.

2. Eligibility

The App is intended for a general audience and is not directed to children under 13. By using the App you represent that you are at least 13 years old (or the minimum age of digital consent in your jurisdiction) and are able to form a binding contract, or that you have the consent of a parent or guardian.

3. Purchases and subscriptions (“ChordPractice Pro”)

The App is free to download and includes optional in-app purchases that unlock premium features (“Pro”). Current plans are:

• Monthly — an auto-renewing subscription billed each month (e.g. US $4.99/month), which may include an introductory free trial for eligible accounts.
• Annual — an auto-renewing subscription billed each year (e.g. US $39.99/year).
• Lifetime — a one-time, non-consumable purchase (e.g. US $99.99) that unlocks Pro on your store account without recurring charges.

Prices are shown in the App at the time of purchase, may vary by region and currency, and may change over time (changes never affect a subscription period you have already paid for, and renewal price changes are subject to the store's notice rules).

Billing, auto-renewal, and cancellation

• All purchases are processed and billed by Apple (App Store) or Google (Google Play) through your store account. We never receive, see, or store your payment details.
• Subscriptions automatically renew at the then-current price unless you cancel at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours prior to the end of the period.
• You can manage or cancel a subscription at any time in your store account settings (App Store: Settings → your name → Subscriptions; Google Play: Play Store → Subscriptions). Cancelling stops future renewals; it does not retroactively refund the current period.
• Deleting the App does not cancel a subscription.

Free trials

If a free trial is offered, it is available only to eligible accounts (generally one per account, ever, as determined by the store). If you do not cancel before the trial ends, it automatically converts to a paid subscription at the applicable price. Any unused portion of a free trial is forfeited when you purchase a subscription.

Refunds

Because purchases are processed by Apple and Google, refunds are handled by them under their policies, not by us. Please direct refund requests to the App Store or Google Play. Where required by law (for example, statutory withdrawal or consumer-guarantee rights), nothing in these Terms limits refund rights you may have.

Restoring purchases

You can restore previous purchases on a new device signed in to the same store account using the “Restore Purchases” option in the App.

4. Acceptable use

You agree not to, and not to permit anyone else to:

• copy, modify, distribute, sell, rent, sublicense, or lease the App or any part of it;
• reverse-engineer, decompile, or disassemble the App, or attempt to derive its source code, except to the extent this restriction is prohibited by applicable law;
• circumvent, disable, or interfere with security, licensing, or purchase-verification features (including to obtain Pro features without paying);
• use the App in any unlawful way or in violation of the app store's terms; or
• remove or alter any proprietary notices in the App.

5. Your data and backups

The App stores your practice data on your device and, if you enable it, in your own private iCloud account. We do not store a copy of your data and cannot recover it for you. You are responsible for maintaining your own backups (for example, using the App's export feature or your device's backup). How we handle data is described in our Privacy Policy, which is incorporated into these Terms by reference. We are not liable for any loss of data.

6. Intellectual property and third-party content

The App, including its design, code, graphics, and content, is owned by us or our licensors and is protected by intellectual-property laws. The App includes bundled third-party assets used under license, including the Salamander Grand Piano V3 samples by Alexander Holm (CC-BY 3.0). Your license to the App does not grant you rights to these assets beyond their use within the App.

7. Disclaimer of warranties

The App is provided “as is” and “as available,” without warranties of any kind, whether express, implied, or statutory, including any implied warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement. We do not warrant that the App will be uninterrupted, error-free, secure, or that it will meet your requirements. Some jurisdictions do not allow the exclusion of certain warranties, so some of the above may not apply to you, and you may have rights that vary by jurisdiction.

8. Limitation of liability

To the maximum extent permitted by law, in no event will we be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, or goodwill, arising out of or relating to your use of (or inability to use) the App. To the maximum extent permitted by law, our total liability for all claims relating to the App will not exceed the greater of the amount you paid us (or via the app stores) for the App in the 12 months before the claim or US $50. Nothing in these Terms limits liability that cannot be limited by law (such as for death or personal injury caused by negligence, or fraud), or your mandatory consumer rights.

9. Indemnification

You agree to indemnify and hold us harmless from any claims, damages, or expenses (including reasonable legal fees) arising from your misuse of the App or your violation of these Terms, to the extent permitted by law.

10. Changes to the App and these Terms

We may update, change, or discontinue the App or any feature at any time. We may also update these Terms from time to time; when we do, we will revise the “Last updated” date above and, where appropriate, provide notice in the App or on this page. Your continued use of the App after changes take effect means you accept the revised Terms.

11. Termination

These Terms apply until terminated. Your license ends automatically if you breach these Terms. You may end it at any time by deleting the App. Provisions that by their nature should survive termination (including intellectual-property, disclaimer, liability, and governing-law sections) will survive.

12. Apple App Store — additional terms

If you obtained the App from the Apple App Store, the following also applies, and you acknowledge that:

• These Terms are between you and us only, not with Apple. Apple is not responsible for the App or its content.
• Your license to use the App is limited to a non-transferable license to use it on any Apple-branded device you own or control, as permitted by the App Store Usage Rules, except that it may be accessed by other accounts via Family Sharing or volume purchasing where applicable.
• Apple has no obligation to provide maintenance or support for the App. Any support questions should be directed to us at the email below.
• To the extent any warranty is not effectively disclaimed, Apple may refund the purchase price (if any); otherwise Apple has no warranty obligation, and any other claims, losses, liabilities, damages, costs, or expenses attributable to a warranty failure are our responsibility.
• We, not Apple, are responsible for addressing product claims, including product-liability, legal/regulatory compliance, and consumer-protection claims, and third-party claims that the App infringes intellectual-property rights.
• You represent that you are not located in a country subject to a U.S. Government embargo or designated as “terrorist-supporting,” and that you are not on any U.S. Government restricted-party list.
• Apple and its subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, have the right to enforce them against you.

13. Google Play

If you obtained the App from Google Play, your use is also subject to the Google Play Terms of Service. Google is not a party to these Terms and is not responsible for the App.

14. Governing law

These Terms are governed by the laws of the Commonwealth of Pennsylvania, United States, without regard to its conflict-of-laws rules, and you agree to the exclusive jurisdiction of the state and federal courts located in Pennsylvania for any dispute not subject to the app stores' own dispute processes. This does not deprive you of any mandatory consumer protections available under the laws of your country of residence.
