What: sound from your microphone, only while you use a microphone feature: the Tuner, Check your playing on a falseta, or Listen to my playing ("Listen to me") in the technique trainers and the backing tracks.
Why: the Tuner hears which note you play and how far it is from the right pitch. Check your playing compares the notes you play with the falseta's tab and gives you a score. Listen to my playing measures when you strike the strings (rhythm, evenness and tempo), which notes or chords you play, and gives feedback while you practise.
Where: analysed in real time in the app's memory on your device. It is never sent anywhere.
How long: the Tuner discards each fraction of a second of sound as soon as it has been analysed. Check your playing and Listen to my playing keep only about the last ten seconds in memory while they are analysed; they are continuously overwritten and deleted when listening stops. Nothing is ever written to storage, sent or shared, and we never have access to it.
Your control: the app asks for permission only when you turn on a microphone feature. Before your phone or browser asks, the app shows a short screen saying what the microphone is used for; you can choose "Not now". If you have refused and your phone will not ask again, the app says how to allow it and, on Android, has a button to the app's settings. The rest of the app works without the microphone. A "Microphone on" bar is shown while it listens, with a button to turn it off. The microphone is only on while a microphone feature is running: Check your playing turns it on at the count-in and off when you press Stop or the check ends; Listen to my playing is on only while its practice or backing track plays and stops when you switch it off or the playing stops; the Tuner listens only while it is switched on and its screen is open. If listening cannot start, the microphone is closed again at once. While the app plays sound and listens at the same time, the microphone uses your device's echo cancellation so it hears you rather than the app, and the app's guitar (Play along, or the backing guitar) stays silent. If you switch on "I use headphones", the app's sound cannot reach the microphone, so echo cancellation is off and the app's guitar can play. The microphone also turns off when you leave the screen, close the app or the app goes to the background. You can withdraw the permission at any time in your phone or browser settings.
Data stored on your device
What: practice history, best tempos, settings, falsetas you mark as learned, falsetas you write yourself, and your best Check your playing score per falseta (a percentage, no audio).
Why: so the app remembers your progress and preferences.
Where: in the app's own storage on your device. The app never sends it anywhere. If you have turned on Android's own backup, Android may include it in your device backup with your Google account, as it does for other apps; that backup is yours and we have no access to it.
How long: until you reset your practice history in the app, clear the app's data or uninstall the app.
Feedback by email
The About page has a "Send feedback or ideas" button and shows our feedback address, feedback@tocaor.com. The button opens your own email app with our address, a subject line and the app version and language filled in. Nothing is sent unless you choose to send that email yourself.
If you do, we receive your email address and what you write. We use it only to reply to you and to improve the app, and we do not share it.
The app itself collects nothing: it does not send anything when you press the button.
Permissions
Microphone (RECORD_AUDIO): asked only when you start a microphone feature, as described above.
Change audio settings (MODIFY_AUDIO_SETTINGS): a standard Android permission granted at install, with no prompt. It lets the app set up the microphone input. It gives no access to your data.
The app has no other permissions, including no internet permission.
Third-party components
The app includes open-source code that runs only on your device and sends nothing anywhere: pitchy and fft.js (MIT licence) for the Tuner, Check your playing and Listen to my playing; Capacitor and its App and Splash Screen plugins (MIT licence), Apache Cordova (part of Capacitor), AndroidX and the Kotlin standard library (Apache License 2.0), which run the app on Android; and the fonts Cormorant Garamond, Cormorant SC and Spectral (SIL Open Font License). The full list and licences are on the About page, under Open-source licences.
Your rights (GDPR)
Because we receive no personal data, we hold nothing about you to access, correct, export or delete. All data stays under your control on your device, and you can delete it as described above. You have the right to lodge a complaint with your data protection authority.
Children
The app does not collect personal data from anyone, including children.
Changes
If this policy changes, we update this page and the date above. Questions: support@tocaor.com.
Changelog
9 November 2026: shortened: the country removed from Who is responsible, the opening sentence made plainer and the section "What the app does not do" removed. Nothing changes in what the app does with your data.
8 November 2026: new contact addresses: support@tocaor.com for questions, feedback@tocaor.com for feedback from the app. Nothing changes in what the app does with your data.
1 November 2026 (3): the microphone now also turns off when Android reports that the app is no longer on screen (besides the signal used before), and when listening fails to start after the microphone opened; a safety check closes it whenever no feature is listening. This policy can now also be read inside the app (About, Privacy policy), offline. Apache Cordova (part of Capacitor) and the Kotlin standard library are now named in the third-party components; they were already in the app. Nothing changes in what the app does with your data.
1 November 2026 (2): the publisher name (Wisabio) added under Who is responsible. Nothing changes in what the app does with your data.
31 October 2026 (2): matched to the Android release: the app does not connect to the internet (no internet permission), the Permissions section lists the microphone and the install-time audio settings permission, Android's own device backup is mentioned, Capacitor and AndroidX added to the third-party components. Nothing changes in what the app does with your data.
31 October 2026: a short explanation now appears before your phone or browser asks for the microphone, with a "Not now" choice and, when access is blocked, a button to the app's settings. The About page now lists the credits and the open-source licences and links to this policy. Contact address added. No new data or third-party code.
28 October 2026: removed Basic Pitch and TensorFlow.js from the app (no longer used since 27 October). Nothing changes in what the app does with your data: it still collects nothing.
1 November 2026: the app is renamed Tocaor (formerly Flamenco Puro). Nothing else changed.
27 October 2026: Check your playing now analyses your playing live, like Listen to my playing, and keeps only about the last ten seconds in memory (no longer the sound of a whole round). New "I use headphones" setting: with it the microphone is opened without echo cancellation. Basic Pitch and TensorFlow.js are no longer used. No new data or third-party code.
25 October 2026: added Feedback by email (About page): feedback is sent only when you choose to send an email, and is used only to reply and improve the app. The app collects nothing itself.
22 October 2026 (5): green and red light while playing along; Check your playing also keeps the last few seconds in memory for it. No new data or third-party code.
22 October 2026 (4): Check your playing is now continuous (microphone on until Stop, each round deleted after its result) and has a Play along option; Listen to my playing now also covers rasgueado. No new data or third-party code.
22 October 2026 (3): Listen to my playing (picado, alzapúa, backing tracks): what is analysed, the few seconds kept in memory, echo cancellation. No new data is stored and no new third-party code was added.
22 October 2026 (2): Check your playing (note checking for falsetas): how the take is kept in memory and deleted, best scores stored on the device, Basic Pitch and TensorFlow.js added to third-party components.
22 October 2026: added the Microphone section (Tuner) and the third-party components; added who is responsible, your rights and a changelog; moved the policy to the project root.
