What Number Tuner does with your information

Number Tuner registers a business’s phone numbers with the carriers, spam-list operators, and call-protection services that decide how calls get labeled — getting a number off a spam-warning or robocall-blocking list is what that registration achieves. You give us your business details and the phone numbers you want registered, once. We use that information to fill out registration and dispute forms at those sites — roughly a dozen different ones. For most of them, our software fills out the form and you click that site’s own Submit button, so the request goes out as you, not as us. A few sites let our software submit the finished form for you once you tell it to.

That is the whole point of the service: your business information gets typed into other companies’ forms, on purpose, because that is how a number gets registered and cleaned. The rest of this page explains exactly what we collect, where it lives, and who else sees it.

What we collect

What you give us directly:

Your business name and address
The phone numbers you want cleaned
A contact name, phone number, and email address
The general category your business falls into, picked from a list, and roughly how many calls you make in a month (a number)
What your calls are about, in your own words — a few free-text sentences, not a fixed answer
A one-line answer, picked from a fixed list, about what’s happening with the numbers this cycle
Your login — either an email and password, or, if you use “Continue with Google,” the name, email address, and profile picture Google shares with us

What we collect automatically:

Standard web traffic information the companies that run our website for us see on every request to numbertuner.com — things like your IP address and browser type. This is the same information any hosted website receives. On top of it we use Microsoft Clarity, described below, to see where the site is hard to use. We also use Google Analytics, described below, to count visits and sign-ups. We do not run advertising analytics.
On most pages there are two cookies of our own: one that keeps you signed in, and one that stops another website from acting on your account without you. Neither is used for advertising, and neither follows you around other sites. Microsoft Clarity sets its own cookies so it can tell one visit from the next. Those are Microsoft’s, and Microsoft’s privacy policy covers them. Google Analytics sets its own cookies so it can tell one visit from the next. Those are Google’s, and Google’s privacy policy covers them. The billing page carries more. The company that processes your payment runs its own code there, and it sets its own cookies alongside ours to catch fraudulent card use — those are theirs, and their own privacy policy covers them.

Where your information lives

Your business details and phone numbers live in a database on our hosting provider’s server while your account is active, and they stay there when we update the app. Each time you save, we add a new copy of your list rather than writing over the last one. That means if you change or remove a number, an earlier copy that still has it can exist for a while after. You can close your account from Settings. Closing keeps everything working until the plan you’ve paid for runs out — nothing stops early, and there’s no partial refund for the time left. After that, your account closes, and your numbers and filing history stay on file. If you come back, your business details and numbers are still there, waiting. We hold it until you ask us to delete it — email us at support@numbertuner.com and we’ll delete it by hand.

Who else sees your information, and why

The phone-company, spam-list, and call-protection sites you clean your numbers through. This is the core of the service — we fill out their forms with your business information so you don’t have to. Once a form is submitted, that site holds your information under its own privacy policy, not this one. We don’t control what happens to your information after it leaves their form.
The companies that run our website for us. They handle every request to numbertuner.com, including the pages you load and the information you submit to us — this is standard for any hosted website and lets the site run at all.
Our error-reporting service. When something breaks, a report goes to the service we use to find and fix bugs. Before a report is sent, we check it for your real phone numbers, name, address, email address, and the reference numbers the sites you file with give back. If any of those appear anywhere in the report, we don’t send a trimmed version — we drop the whole report instead. If that check doesn’t run, the report is sent without it. This check is a setting we maintain, not a guarantee that can never fail. Any report that is sent is kept for up to 30 days, then removed.
Google, only if you sign in with “Continue with Google.” We receive your name, email address, and profile picture from your Google account to create and log you into your Number Tuner account. We don’t request access to your Gmail, Drive, Calendar, or any other Google data, and we don’t use your Google account information for anything besides signing you in.
The company that processes your payment. When you start a subscription, we hand it your name, your email address, and the reference number your account has with us, so it can bill you and tell us the payment went through. Its own code runs on the billing page to take your card number — that number goes straight to them, never to us. What they hold after that is covered by their own privacy policy, not this one.
The free tool behind “Which carrier is each number on?” on the Check Status page. That tool is run by another company, not by us. When you use it, the numbers you’re asking about go straight from your browser to them — nothing else, not your name and not your business details. Once the numbers are there, their own privacy policy covers them, not this one.
Microsoft Clarity, which shows us how people use the site. It records clicks, scrolling and which pages you visit, so we can see where the site is hard to use. It hides everything you type, and on pages you see while signed in it hides everything on the screen too.
Google Analytics, which counts visits and sign-ups. It records which pages are visited and when someone finishes signing up, along with the browser type and a rough location, so we can see how many people find the site and how many join. It does not see what you type.

We do not sell your information, and we do not share it with anyone else for their own marketing.

“Numbers never leave the machine”

If you’ve heard that phrase from us before, it described an earlier version of this tool that ran entirely on one person’s own computer, with no server involved at all. That’s no longer how Number Tuner works, and we want to say plainly what’s true now instead of repeating a claim that no longer fits:

Your phone numbers live on our hosting provider’s server while your account is active — see “Where your information lives” above.
Your phone numbers are deliberately typed into the phone-company and spam-list portals you choose to clean them at. That’s the product.
Your phone numbers are kept out of our own bug-report system by the filtering described above.

Email

We send a few kinds of email. When you sign up, we send one confirming your email address, and once you confirm it, one welcoming you in. If you join the waitlist, we send one message letting you know you’re on it. We also send the ordinary account emails most sites send — things like a password reset if you ask for one. Every waitlist email carries a link to unsubscribe. We don’t put your phone numbers in any email we send. Email records are kept for up to 30 days after they’re sent.

Security

We encrypt traffic between your browser and our servers. No method of storing or sending information over the internet is completely secure, and we can’t promise your information will never be exposed. We haven’t obtained any outside security certification or audit for Number Tuner.

Chrome extension

The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.

The Number Tuner Chrome extension talks to numbertuner.com. It sends which registration or spam-review page you have open (by site name, not the full address), asks for the approved version list, and asks for the form details tied to your account so it can fill the page in front of you. When you are signed in to Number Tuner, it also tells us that it is installed and which version, at most once every half hour. It never reads a password or a cookie for any other site.

When Number Tuner adds a site the extension can work on, Chrome asks you once to allow it. The extension does nothing on that site until you do, and you can take the permission back in Chrome’s extension settings.

Some spam-label services take review requests through their help desk. When you start one of those in Number Tuner, we prepare the request from your account: your business name, your contact email, the phone number you asked about and the words of the request. The extension sends that request to the service from your browser, without your cookies. As with any website your browser contacts, the service also sees your IP address and your browser’s details, such as its name and version. Once the service has the request, their own privacy policy covers it, not this one. The extension then tells us how each request went, and we keep that with your account: whether it went through, and the service’s request number or a short error message when it gives one.

Changes to this policy

If we make a material change to what this policy says — for example, starting to share information with a new kind of third party — we will not apply that change to information we already collected without telling you first. We’ll post the updated policy here with a new “last updated” date, and if we have a way to reach you, such as an email on file, we’ll let you know.
