This site was designed to collect as little data as possible. You do not need to create an account, and no audience-analytics services are used.
This page explains what information may be processed while you use the site. For details about browser storage and external checkout technologies, see the cookie policy.
Using the tool
Choices made in the diagrams, such as instrument, scale, key, and display options, are processed in the browser.
Some preferences may be stored locally on your device so they persist between visits. This information does not require personal identification and can be removed through your browser settings.
The cookie policy describes the locally stored data in more detail.
Microphone and tuner
The tuner requests microphone access only when you start the feature.
The audio is analyzed directly in the browser to determine the note’s pitch. The site does not record or send the audio to a server.
Permission to access the microphone is controlled by the browser and can be changed in your device or browser settings.
Contact
If you contact us by email, we receive the information you voluntarily include in your message, such as your email address, name if provided, and the content you send.
This information is used to respond to your request and maintain the necessary communication about the matter.
To get in touch, use the contact page.
Hosting and technical data
As with any site available on the internet, the providers responsible for delivering and securing the pages may process technical information needed to establish a connection, such as your IP address, browser, requested page, and the date and time of the request.
This processing is part of the infrastructure needed to make the site available and protect it from abuse.
No affiliate monetization
The site currently does not display product or affiliate links. Skimlinks and other affiliate providers are not loaded, and this site does not create affiliate cookies or process affiliate click attribution.
Contributions and payments
If you choose to make a voluntary contribution to the project, the support panel opens a modal with four locale-specific Stripe links: three fixed amounts and one custom amount. The Portuguese options are BRL 5, BRL 10, BRL 20, and a custom amount; the English options are USD 2, USD 5, USD 10, and a custom amount.
Stripe may receive and process the information needed to complete the transaction, such as payment details, contact information, and other data required by the payment method used.
This site does not receive or store your full card details, create a Stripe Checkout Session, or keep a contribution record. Stripe handles the hosted checkout and the information required for the selected payment method.
Processing carried out by Stripe is also subject to Stripe’s own privacy policy.
Your rights
Depending on applicable law, including Brazil’s General Data Protection Law (LGPD), you may have rights regarding your personal data, including requesting information about its processing, access, correction, or deletion where applicable.
Locally stored preferences can be removed directly through your browser settings. There are no site consent choices to withdraw.
For requests concerning information sent directly to the site, use the contact page.
