Terms & Conditions

1. Overview

These Terms and Conditions govern your use of Tonemap ("the Service"), an intonation visualization tool for musicians available at tonemap.live and as a native app for iPhone and iPad. By using the Service, you agree to these terms.

Tonemap is an independent, open-source project, designed by Jeremy Black. The source code is publicly available, the core tool is free to use, and a paid Pro tier exists solely to support its continued development.

Many thanks to all those who helped test and provided feedback during development, including Jeremías Sergiani-Velázquez, Jonathan Yi, Boxianzi Ling, Kate Lewis, Ken Johnson, and Ryan Black; and the support and patience of my wife, Kate Black!

2. Free Tier

Tonemap's core features are available free of charge with no account required. The free tier includes real-time pitch detection, color-grid visualization, Note View, and basic tuning options.

3. Tonemap Pro Subscription

Tonemap Pro is an optional paid subscription available at $9.99 USD per year, providing access to extended features. A Pro subscription is how Tonemap stays independent: no advertising, no outside funding, no selling of user data. If you find the tool useful, Pro is the way to support it.

Subscriptions are billed annually and renew automatically unless cancelled. Cancellation takes effect at the end of the current billing period — you retain Pro access until then.

On the web (tonemap.live), payments are processed securely by Polar, and you may cancel at any time through your account portal or by contacting us. Tonemap does not store your payment information.

In the iOS app, the subscription is purchased through the App Store and billed to your Apple Account. It renews automatically unless cancelled at least 24 hours before the end of the current period, and can be managed or cancelled at any time in your device's App Store subscription settings. Apple handles the transaction; Tonemap never receives your payment details.

The two subscriptions are independent: an App Store subscription unlocks Pro in the iOS app, and a web subscription unlocks Pro at tonemap.live.

4. Refund Policy

For subscriptions purchased on tonemap.live: if you are unsatisfied, contact us within 30 days of purchase for a full refund. Requests after 30 days are considered on a case-by-case basis. To request a refund, email support@tonemap.live.

For subscriptions purchased through the App Store, refunds are handled by Apple. Request one at reportaproblem.apple.com.

5. Use of the Service

Tonemap is provided for personal, educational, and professional music practice purposes. You may not redistribute or replicate the Service as your own product except as allowed by the MIT license. You are responsible for ensuring your device meets the requirements to use the Service (a modern browser, or an iPhone or iPad, with microphone access).

6. Privacy & Data

Tonemap processes audio input locally on your device — in your browser using the Web Audio API on the web, and entirely on-device using Apple's audio frameworks in the iOS app. Audio and usage data is never transmitted to or stored on our servers.

Basic, anonymized page-view statistics may be collected on the tonemap.live website to understand how the tool is being used. The iOS app contains no analytics or tracking frameworks and collects no data. No personally identifiable information is collected from free-tier users, and no data is sold or shared with third parties. Web Pro subscribers provide an email address and payment information solely for billing purposes; this is handled by Polar in accordance with their privacy policy. App Store subscriptions are handled entirely by Apple; see Apple's privacy policy.

Authentication cookie (web app). When you activate a Tonemap Pro license on tonemap.live, a strictly necessary cookie named tm_pro is set in your browser. This cookie contains a cryptographically signed token that proves your device has an active Pro license — it does not contain your name, email address, or any other personally identifiable information. The cookie is required to serve Pro content; the server cannot verify your device's authorization without it. Because it is strictly necessary to deliver the service you explicitly requested, it does not require a separate consent prompt under GDPR, the ePrivacy Directive, or comparable regulations. Your license may be activated on up to five devices simultaneously; you can deactivate a device at any time from within the web app to free a slot. License keys apply to the web app; the iOS app uses App Store subscriptions and sets no such cookie. The cookie persists for up to one year and is refreshed automatically when your license is revalidated. Tonemap's server infrastructure runs on Cloudflare.

7. Open Source License

The Tonemap client-side source code is released under the MIT License. You are free to use, copy, modify, merge, publish, distribute, sublicense, or sell copies of the software, subject to the following condition: the above copyright notice and this permission notice must be included in all copies or substantial portions of the software.

The MIT License applies to the software code itself. It does not grant any rights to the Tonemap name, logo, or tonemap.live domain, and does not entitle anyone to a Tonemap Pro subscription without purchase. The code being open is intentional: you can read exactly how Tonemap handles your microphone input and verify that nothing leaves your device.

8. Trademark

Tonemap™ is a trademark with a pending registration. All rights reserved. Use of the Tonemap name or mark in connection with any product, service, or domain requires express written permission.

9. Disclaimer of Warranties

THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NONINFRINGEMENT. IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES, OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF, OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.

Pitch detection accuracy depends on your device, microphone, and acoustic environment. We do not guarantee specific intonation analysis results.

10. Limitation of Liability

To the maximum extent permitted by applicable law, Tonemap and its creator shall not be liable for any indirect, incidental, or consequential damages arising from your use of or inability to use the Service.

11. Changes to These Terms

We may update these terms from time to time. Continued use of the Service after changes are posted constitutes your acceptance of the revised terms. The date at the top of this page indicates when the terms were last updated.
