Privacy policy

Effective and last updated: September 8, 2026

Intoniva is published by MajkeyLab. Privacy contact: majkeylab@gmail.com.

Intoniva is an offline Android music tool. It has no accounts, advertising, analytics, profiling, tracking, maintainer-operated server, or Android Internet permission. MajkeyLab does not collect, sell, or share data through the app.

On-device processing

Intoniva uses microphone access while the tuner is active. Samples are processed transiently in memory to estimate pitch and are not recorded, retained, uploaded, or shared.

When you select a song through Android's document picker, Intoniva can read that file to estimate chords, notes, tempo, and an acoustic arrangement. The source file is not copied or uploaded. Analysis results remain in memory and disappear when replaced or when the app process ends.

Settings, favorites, custom tunings, metronome settings, Auto-scroll acceptance, and trainer scores remain in private local app storage. Delete them by clearing app data or uninstalling Intoniva.

Auto-scroll is optional. If enabled in Android Accessibility settings, it performs deterministic swipe gestures initiated through the floating controls. Its configuration disables window-content retrieval. It does not read, inspect, record, store, or transmit screen content. Closing the controls stops scrolling.

MajkeyLab receives no personal data from this local processing. Where a legal basis is required, processing is necessary to provide the feature you request and reflects MajkeyLab's legitimate interest in providing an offline music tool. There are no app recipients or international transfers.

External links and optional support

The support button asks Android to open Buy Me a Coffee in an external browser. The app sends no identifier and unlocks no feature. The browser and destination apply their own privacy terms.

If you make an optional support payment, the service may make your chosen name, contact details, message, and transaction reference, date, or amount available to MajkeyLab. These records are used for support-payment enquiries and required legal recordkeeping, based on the requested transaction, legitimate interests, or the relevant legal obligation. Payment records are kept for the time needed to resolve the enquiry and any applicable legal retention period. Full card details are processed by the payment provider, not Intoniva. See the Buy Me a Coffee Privacy Policy.

If you voluntarily email MajkeyLab or open a GitHub issue, MajkeyLab and the email or GitHub provider may receive the address or account name, message, and attachments you choose to send. Do not attach recordings or sensitive data. MajkeyLab uses correspondence only for requested support, abuse prevention, or legal obligations. The legal basis is steps requested by you or MajkeyLab's legitimate interests. Private support correspondence is normally deleted within 12 months after the request closes, unless you request earlier deletion or a legal duty requires longer retention. Provider processing and international transfers follow that provider's terms and safeguards.

GitHub issues are public. Use email for private requests. Public issues may remain in the project's history until edited or removed; the private-support retention period does not apply to them. Copies held by other people or services are outside MajkeyLab's control and cannot be erased by MajkeyLab.

This website and hosting

This website has no contact form, analytics, advertising pixels, third-party embeds, cookies, or browser-storage identifiers set by Intoniva. No marketing consent is requested. See the cookies policy.

GitHub Pages hosts the website and logs visitors’ IP addresses for security. GitHub processes technical requests under its Privacy Statement, including its retention and international-transfer provisions. MajkeyLab does not receive a visitor analytics dashboard or use this data for advertising.

European Union and EEA rights

Subject to applicable law, you may request access, correction, deletion, restriction, portability, or object to processing by contacting majkeylab@gmail.com. You may complain to the data-protection authority for your residence, work, or the alleged infringement. MajkeyLab has no server-side app record to access, correct, export, or delete; requests can apply to optional support correspondence.

United States privacy rights

Intoniva does not sell or share personal information, use targeted advertising, offer a financial incentive, or discriminate after a privacy request. MajkeyLab may receive the optional support and payment information described above. Contact majkeylab@gmail.com to exercise rights that apply in your state.

Children

Intoniva is a general-audience music tool and is not directed to children. The app does not collect personal information. A child must not send personal information through optional support without a parent or guardian.

Changes

MajkeyLab will update this policy before distributing a version that materially changes data handling.
