Privacy

What we collect, why, and who else touches it.

Last updated 12 November 2026

We collect what you hand us and almost nothing else. No analytics, no cookies, no advertising pixels, no tracking of any kind. This page says exactly what the site does with the rest.

01 Who we are

COET is a design and engineering studio with offices in Scottsdale, Arizona; Milan, Italy; and Carbondale, Illinois. We are the controller of the personal information described here. Our contact details are in section 11.

02 What we collect

What you send us

If you fill in the project form, we get your name, your email address, your company if you choose to give it, and what you tell us you are building. The form also lets you mark a preferred day and time for a call. That is a preference attached to your message, not a booking — there is no calendar system behind it. When you pick a time, the form sends the time you chose, your time zone as your browser reports it, and the same moment converted to Phoenix time, so we know what you meant.

That goes to our own server, and we keep it as one row in our own database. Stored with it are the time you sent it, the IP address it came from, and which site it was sent from — we keep those to deal with abuse of a form anyone on the internet can post to, and for no other purpose. We then send ourselves a notification and send you a confirmation email, which repeats your message and the time you asked for so you can see we read it the way you meant it.

The form has one hidden field that is a spam trap. It is empty for anyone using a browser normally, and a submission that fills it is dropped without a row being written.

Voice conversations

One ball in the globe starts a spoken conversation with our voice agent. Nothing listens until you click it. Your browser then asks for permission to use the microphone, and the call only begins if you grant it. While the call is running, your audio streams to ElevenLabs, who run the agent: they turn your speech into text, generate the reply, and speak it back. The call ends when you say stop, click the ball again, press Escape, leave the page, or the agent hangs up. Refusing the microphone, or never clicking, means no audio ever leaves your device.

We do not record these conversations ourselves. ElevenLabs processes the audio on our behalf under their own terms, which can include keeping audio and transcripts for a period.

What our host and our font provider see

Like any website, loading a page tells the server who is asking. Our host keeps standard request logs: IP address, browser and operating system, the page requested, the time, and the page you came from. We use these only to keep the site up and to deal with abuse.

The typeface is served by Google Fonts, so your browser asks Google for it. That request shows Google your IP address and browser. It is not used to log you in to anything and we get nothing back from it.

What stays on your device

The site saves two preferences in your browser's local storage: whether you chose the light theme, and whether you turned interface sound on. They are the words light, dark or an on/off flag — no identifier, nothing about you, and they are never sent anywhere. Clearing your browser storage removes them. The site uses no cookies, so there is no cookie banner to dismiss.

The call scheduler reads your time zone from your browser so the calendar shows your own hours. That reading stays in the page unless you pick a time and submit the form.

What we do not do

No analytics or measurement service. No advertising or social pixels. No cookies. No fingerprinting, profiling or automated decision-making. No cross-site or cross-app tracking. We do not buy personal information about you, and we do not sell or share yours.

03 Why we use it

  • To answer you. We read what you send and reply, which is us taking steps toward the work you asked about, and our legitimate interest in running a studio people can contact.
  • To run the voice agent. Your microphone is used on your consent, given through the browser permission prompt, and withdrawn by ending the call or denying the prompt.
  • To keep the site working and secure. Server logs and the spam trap, on our legitimate interest in a site that stays up and an inbox that is not full of bots.

Where the GDPR applies, those bases are Article 6(1)(b), 6(1)(a) and 6(1)(f) respectively.

04 Who else handles it

Four companies, each doing one job for us, each bound to use the data only for that job:

Beyond those, we disclose personal information only if the law requires it, or to protect our rights, safety or property. If COET is ever bought or merged, inquiries in our inbox may move with the business; this page would be updated to say so.

05 How long we keep it

Your inquiry is a row in our database and a thread in our inbox. Both stay while we are talking and for as long as we have a working relationship. If nothing comes of it, we delete the row and the thread within 24 months. Ask us to delete them sooner and we will. Server logs and anything held by the services above are kept on their own schedules, which we do not control. Your theme and sound preferences live on your device until you clear them.

06 Where it goes

We work in the United States and in Italy, and the services we use are mostly United States companies, so your information is processed in the United States. If you are in the European Economic Area, the United Kingdom or Switzerland, that is a transfer out of your region. Where it is required, we rely on the European Commission's Standard Contractual Clauses, or on the provider's certification under the EU–US Data Privacy Framework, to cover it.

07 Your choices and your rights

You can refuse the microphone, skip the form, and clear your stored preferences at any time, and the site still works. Beyond that, write to us and we will act on it.

If the GDPR or UK GDPR applies to you, you have the right to know what we hold, get a copy, correct it, have it deleted, restrict or object to how we use it, take it elsewhere in a portable form, and withdraw consent you gave. You can also complain to your national data protection authority.

If you live in California, you have the right to know what we collect and why, to get a copy, to have it corrected or deleted, and to opt out of sale or of sharing for cross-context behavioural advertising. We do not sell or share personal information and we have not in the last twelve months, so there is nothing to opt out of. We will not treat you differently for exercising any of this. Similar rights in Colorado, Connecticut, Virginia, Utah and other states are handled the same way.

We answer requests within 30 days, or 45 days in California, and we may ask you to confirm who you are before we act on one. We do not track you across sites, so a Global Privacy Control or Do Not Track signal has nothing here to switch off — we honour it regardless.

08 Children

This site is for people doing business with us. It is not for children, and we do not knowingly collect anything from anyone under 16. If a child has sent us something, write to us and we will delete it.

09 Security

The site is served over HTTPS and the voice call is encrypted in transit. These pages are static files with no account and no login, so there is nothing here to sign in to and nothing here to break into. Your message is stored in a private database that is not reachable from the public internet, and it arrives in an inbox with two-factor authentication on it. Access to both is limited to the people who need it to answer you. The endpoint the form posts to accepts only our own sites, rate-limits what one address can send, and caps the length of every field. No system is perfect, and we will tell you and the relevant regulator if a breach affects you.

10 Changes

When the site changes what it collects, this page changes with it, and the date at the top moves. If a change is significant, we will say so plainly here rather than quietly reword the page.
