In short
Finding a song needs no account, and HumFinder has no ads, no analytics and no tracking cookies. It uses your microphone only after you press a button. Recordings are not saved.
Who runs HumFinder
HumFinder is run by Humfinder. Contact us at [email protected].
When you listen for a song
Your browser records up to twelve seconds of sound and turns it into a fingerprint on your device. Only the encrypted fingerprint is sent to our server. The recording never leaves your device.
When you hum
Your browser normally reads the tune on your device and sends only that, encrypted. It downloads a small model the first time to do this. If your browser can't run it, the recording is sent to our server, encrypted, kept in memory just long enough to read the tune, up to about a minute when the server is busy, and then discarded. It is not written to disk or kept.
What we do store
If you press "That's my song" or "None of these", we store your answer, the song and the time, so results can improve. It is not linked to you.
If you tick the box to save your tune and pick a song, we store the notes of your hum with that song, so others humming it can find it. We never store the sound of your voice. We also store a one-way code made from your IP address, so one person can't count as many. It can't be turned back into your address, and it isn't linked to your name or email.
Your IP address is held in memory for up to a minute to limit abuse. Our hosting and network providers may also keep ordinary technical logs, which can include IP addresses.
If you add music
We store your email address, a sign-in cookie that is only used to keep you signed in, the details and links you enter, the fingerprints and melody data from each song, its file details, and your confirmation that you have the rights. The uploaded audio is deleted once processing ends.
Other companies
Our server is hosted by Hetzner. Sign-in and review emails are sent through Resend, which receives your email address to deliver them.
If you press Play on a song we don't host, your browser may load a preview directly from Apple, which sees your IP address. Links to YouTube, Spotify and Apple Music take you to those services, under their own privacy policies.
Your choices
You can find songs without giving a name or email. You can block the microphone in your browser at any time. For any privacy question or request, write to [email protected]. HumFinder is not directed at children under 13.
