We never collect anything without asking, and we never collect who you are or what you listen to. Right now the Attune app collects nothing at all, and this website stores an email address only if you choose to give us one.
These are not settings you can turn on. We do not collect them and do not intend to build the ability to: your identity, your contact details, your listening history, the contents of your music library, your file paths, or anything else that could be tied back to you as a person. A tuning you make is yours; what you play through it is not our business.
Attune currently collects, stores, transmits, and shares nothing. It runs entirely on your Mac, has no network access, and contains no analytics, telemetry, or tracking of any kind. Audio files you choose are read locally only to play them — nothing about your music library, your listening, or your tunings ever leaves your device.
Something you send yourself. If you use Have feedback?, the app writes a message and opens it in your mail client, with the technical context it attaches — app version, macOS version, output device, which headphone pair is loaded — shown to you in the window before you send it. You send it; we don't.
We may one day want crash reports, so bugs get fixed without someone having to write in, or anonymous results from the listening exam, so the house target improves for everyone. If we build either, all of the following are binding: it is off by default; we ask once, in plain language, and say what it's for; you can see the exact payload before you agree and any time after; one click turns it off permanently; and this page is updated first, before the feature ships, never after. Still nothing from the list above, and still nothing tied to you. A pre-ticked box, a consent bundled into something else, or a friendly dialog that defaults to yes would all break that promise, so we won't use them.
If you enter your email address in a signup, waitlist, measurement-request or feedback form, we use it only to reply and to contact you about Warren Labs. It is stored by our form provider (Formspree) and by us, and is never sold or shared with advertisers. Ask us to delete it at any time. The site sets no advertising or cross-site tracking cookies. The feedback form attaches the page you were on, your window size and your browser version — shown to you before you send — and email is optional there.
If you send a headphone in, we need your name and address to ship it back, and we keep them for that. Published measurements carry a credit line only in the form you choose: your name, a handle, or nothing at all.
Attune earns nothing from what you decide to buy, so the app has no reason to want a profile of you. Not collecting it isn't a sacrifice; it's just what this product doesn't need.
