Privacy policy.

01 · Scope and controller

Who this policy covers.

This privacy policy applies to the Tuner iPhone app and the Tuner pages on byelias.dev. The responsible developer and data controller is Elias Haghverdi, operating as Bonsai Media. Provider and contact details are available in the Impressum.

02 · Microphone access

Used only to detect pitch.

Tuner needs microphone access to detect the pitch of a note. Audio input is analyzed in real time on your iPhone to calculate the detected note, frequency, and tuning offset.

03 · Data storage

No app data is stored.

Tuner does not store audio, detected notes, frequencies, tuning history, user profiles, identifiers, or app settings. A selected reference pitch and live tuning measurements are used only while the app is running. Tuner does not require an account or operate a server for app data.

04 · Analytics, ads, and tracking

No advertising or cross-app tracking.

• Tuner does not include third-party advertising.
• Tuner does not sell personal information or microphone input.
• Tuner does not track you across apps or websites owned by other companies.
• Tuner does not use third-party analytics SDKs to profile app usage.

05 · Website and contact

Information you send deliberately.

If you contact support, the developer receives the information you choose to send, such as your email address, message, device details, and attachments. It is used to answer your request and diagnose a reported issue.

When these public pages are visited, the hosting infrastructure may process ordinary technical request information such as an IP address, timestamp, requested page, and browser information to deliver and protect the website. Website request data is not connected to microphone input inside Tuner.

06 · Retention, deletion, and rights

You remain in control.

Tuner does not retain microphone audio or other app data. You can revoke microphone permission at any time in iOS Settings; Tuner cannot detect pitch without it.

Depending on applicable law, you may have rights to access, correct, erase, restrict, or object to processing of personal information held by the developer. For website or correspondence requests, use Tuner Support.

07 · Changes

If the app changes, this policy changes too.

This policy will be updated if Tuner introduces a new data practice, service provider, or feature that materially changes how information is handled. The revision date at the top identifies the current version.
