ArcaLyra processes personal data only to the extent technically necessary to provide the app’s functions.
The app does not require a user account, login, online connection, advertising system, analytics system, or tracking service.
All data created or imported within ArcaLyra, including sheet music, images, annotations, settings, markings, and edited files, is stored locally on the user’s device.
ArcaLyra does not automatically transmit this data to the developer, to external servers, or to third parties.
ArcaLyra requests access to the device camera.
The camera is used only to photograph or scan sheet music inside the app.
Images captured with the camera are processed locally on the device. They are not automatically uploaded, shared, or transmitted to the developer or to third parties.
ArcaLyra may request access to the device microphone.
The microphone is used only for the tuner function.
Audio input is processed locally for tuning purposes. ArcaLyra does not record, permanently store, upload, or share microphone audio.
ArcaLyra may access files selected by the user in order to import, display, edit, or store sheet music and related documents.
Imported and edited files remain locally on the user’s device unless the user manually exports or shares them through another app.
ArcaLyra uses Google Play Billing to manage subscriptions.
Payment, billing, and subscription data is processed by Google.
ArcaLyra itself does not receive full payment details and does not store payment information.
For local license verification, ArcaLyra stores only a technical subscription verification status on the device.
This allows the app to be used offline for up to 14 days after the last successful online subscription check.
This information remains local on the device and is not transmitted to the developer.
If users send feedback, bug reports, or support requests, this is done through the email application installed on the user’s device.
Only the information entered by the user into the email is transmitted. ArcaLyra does not automatically collect or attach personal data.
ArcaLyra does not use advertising networks, tracking technologies, analytics tools, or third-party profiling services.
ArcaLyra itself does not use external services for processing user content.
When downloading or using the app through Google Play, data may be processed by Google according to Google’s own privacy policies. The developer has no control over this processing.
