Terms of use

Updated on 17 October 2026. FretUp is developed by Breno Mayder and distributed on the App Store by S&S SOLUCOES EM TI LTDA. Contact: breno@mayder.com.br.

Purpose

FretUp supports guitar study. Content, exercises, the tuner and other tools do not replace professional guidance or guarantee learning results. Stop practising if you feel pain or discomfort and seek suitable guidance.

Use and content

Use the app lawfully and respect rights to the software, brand and content. Third-party materials retain their licences and attribution, available in About and credits in the app. These terms do not restrict rights granted by open-source licences.

Device and local data

Features depend on device compatibility and, where needed, system permissions. Progress and preferences are stored locally. Uninstalling, clearing data or losing the device may remove this history. Read the privacy policy to learn how data is handled.

Updates and availability

Improvements and fixes may be distributed through the stores. Some versions may require an update to keep using the app while a valid remote rule is active. Download and installation depend on the store, connection and device compatibility. An unavailable or expired configuration check does not prevent offline access in this implementation.

Stores and applicable rights

Downloads and updates are also subject to the terms of the store you use. These terms do not exclude mandatory guarantees or rights under applicable law. Questions and issues can be sent to support.
