What we know about you.

Your measurements never leave your machine. The recordings, the analyses, the filters and your rooms are stored in audiolaz’s data folder on the computer you installed it on. Nothing is uploaded, and there is no account to create.

Activation. When you type your licence key, audiolaz sends to our activation service that key, the identifier of its installation on your computer, the computer’s name and the version of audiolaz. From the version that brings Room and Room Plus, it also sends its language and, if a licence is already active on that computer, that licence, to which an upgrade adds Room Plus. The service sends back a signed licence file. Afterwards the licence is checked on your own machine, offline, for ever — audiolaz keeps working with no internet connection at all.

We keep, for each key: the key itself, the identifier and name of the computer it is bound to, the buyer’s e-mail as provided by the store, the sale reference, the version of audiolaz, the dates of activation and, for an upgrade, the Room key it was added to. This is what lets us honour a machine change or a refund. We keep it for as long as the licence exists.

Update check. Every 15 minutes, and when you open its first screen, audiolaz asks audiolaz.com for the number of the latest version, so it can tell you when a newer one exists. The request carries nothing about you or your machine, and nothing is kept.

A Linux Core’s password. To install your filters on a Roon Core running Linux, the app asks for the Core’s password once. It uses it on your network to set up its own access to the Core, then forgets it: the password is never written to a file or a log, and never sent to us.

Secure address. So that your phone can open audiolaz without installing anything, the software asks audiolaz.com for a name of its own under lan.audiolaz.com that points at the computer’s address on your home network (for example 192.168.1.80), and obtains a certificate for that name from Let’s Encrypt. We keep that name and that local address, and nothing else: the certificate’s private key is made on your computer and never leaves it, and nothing about your rooms travels. If your router refuses such names, the software falls back to its own certificate, as before.

The iPhone app. The audiolaz Room app for iPhone looks for the computer running audiolaz Room on your home network and shows its screens. When you measure, it records the measuring sound with the phone’s microphone and sends the recording only to that computer, on your network. When you measure how the sound and the picture line up (Apple TV, AirPlay video), it films the screen with the phone’s camera at your seat: the picture is read on the phone itself and kept nowhere: only the brightness of its centre, frame by frame, goes with the recorded sound to that computer, on your network. It sends nothing to us, collects no data, shows no advertising and has no account.

Reports. If you tap “Send a report” in the app, audiolaz sends us what it knows about your installation — its version and system, what Roon answers, the names and states of your zones, its last error messages, the phone’s browser string — together with the words you typed. Never a recording, a measurement or a filter. We keep the report until the matter is settled, and use it for nothing else.

Discussion. audiolaz.com/discussion holds questions and answers about audiolaz Room, open to everyone and read by search engines. What you post there is public, with the name you give and the time; a beta tester posting from their own page appears with their first name and “beta tester”. A visitor’s message is published once we have read it. To limit the messages a day, a fingerprint of your address mixed with the day is kept for two days, never the address itself. No account, no e-mail address, no cookie. Ask us and we take a message out. A beta app asks audiolaz.com every 15 minutes for the times of the latest messages, to say how many are new: nothing about you goes with the question.

The online link. If you use the optional link that lets your phone reach audiolaz from outside your network, requests pass through that relay encrypted and are not stored there.

No cookie, and nothing that identifies you. We count visits to know what people read. Each page view, and a few clicks (measure, buy, tell me when, contact, the before/after switch, a section opened), send a short note to audiolaz.com itself. All we keep is a count per day: the page, the site you came from (its name, not the full address), the campaign name if the link you followed carried one, your country, the kind of screen (phone, tablet or computer) and the button. Your IP address and browser are read for that one request, to set robots aside and find the country, and are not stored. Nothing is written on your device, nothing is shared, and one visit cannot be linked to the next. The daily counts are deleted after 25 months.

Not counted: browsers that send “Do Not Track” or “Global Privacy Control”. You can also opt out here, which only stores that choice in this browser:

Told when it opens. If you leave your e-mail address to be told when audiolaz Room opens, we keep that address, the language and the page you left it on, the country your connection comes from, and the time. Your IP address is not kept: to limit the addresses left from one connection, a fingerprint of it mixed with the day is kept for two days, never the address itself. Your e-mail address is used only to tell you that audiolaz Room is open, shared with no one, and deleted once that announcement is sent, unless you have become a customer by then. To be taken off the list before that, write to contact@audiolaz.com.

No third-party script, no third-party font. The host, Cloudflare, processes the technical data of each request (IP address, browser) to deliver the site and protect it, as every web host does.

If you apply to test audiolaz Room with the form, we keep what you type in it (name, e-mail, your setup, and the optional answers and note you add), the language of the page, the country your connection comes from, and the time. Your IP address is not kept. It is used only to choose the testers and to answer you, shared with no one, and deleted six months after sales open.

During the beta, a tester measuring with a calibrated microphone can record the listening seat once more with the phone’s own microphone, to compare the two. Only if you tick “Send both measurements to audiolaz”, audiolaz Room sends us the curves of these two measurements (the response of each speaker as the app computed it), the names of the two microphones, your phone’s browser version, the app version and the name on your licence. Never the sound itself, and not your IP address. They are used only to make phone measurements more accurate, shared with no one, and deleted six months after sales open.

Payment is handled by Gumroad, Inc., which acts as the seller of record. Your name, e-mail, payment details and billing country are collected and held by Gumroad under its own privacy policy. We never see your payment details. We receive your e-mail address and the sale reference, which we use to issue and support your licence.

You may ask for a copy of what we hold about you, ask us to correct it, or ask us to delete it. Write to contact@audiolaz.com. Deleting a licence record means the key can no longer be reactivated — the licence already installed on your machine keeps working, since it is checked offline.
