Privacy policy

Last updated November 12, 2026

This policy explains what information MediaMetrix ("MediaMetrix", "we", "us") collects when you visit our website, fill in one of our forms or use the MediaMetrix reporting service, and how we use and protect it. If you have questions, email us at hello@mediametrix.ai.

What we collect

Information you give us

Demo, plan and one-pager forms. Your name, work email, phone number, company, the number of clients or brands you report on, the platforms you use, any message you send us, and whether you agreed to receive emails or text messages from us.
Your account. If you create a MediaMetrix account, your name, email address and password (stored only as a secure hash). If you sign in with Microsoft or Google, we receive your name and email address from them. We never see your Microsoft or Google password.
Platform access. The access keys or tokens you add so we can connect to your ad platforms, such as Meta, Google Ads and CallRail.

Information collected automatically

Form records. When you submit a form, we record the time, your IP address and your browser's user agent, along with the exact consent wording you agreed to, so we can keep an accurate record of your request and your consent.
Technical data. Like most websites, our servers keep basic logs (such as IP address, pages requested and error details) to keep the site secure and working.

Data from your ad platforms

When you connect an ad platform, we pull advertising performance data (such as spend, impressions, clicks, conversions and calls) for the accounts you choose, so we can build and update your reports. We use this data only to provide the service to you.

How we use it

To respond to your demo or plan request and set up your account.
To give you access to the one-pager you asked for.
To build, update, monitor and maintain your reports and dashboards.
To write the plain-language performance and pacing summaries in your reports, using an AI service (see Who we share it with).
To send you updates about MediaMetrix by email or text, but only if you agreed to receive them.
To keep the site and service secure, prevent spam and abuse, and meet our legal obligations.

We do not sell your personal information, and we do not use your ad platform data to advertise to you or anyone else.

Email and text messages

Our forms ask separately whether we may email you and whether we may text you. Both are optional. We'll still reply about your request if you leave them unticked.

Email. You can unsubscribe at any time using the link in our emails, or by emailing hello@mediametrix.ai.
Text messages. Message frequency varies. Message and data rates may apply. Reply STOP to opt out at any time, or HELP for help. Consent to receive texts isn't a condition of buying anything from us.

We do not sell, rent or share your mobile number or your text-message consent with third parties or affiliates for their own marketing purposes.

Cookies

We use a small number of cookies that the site needs to work:

Sign-in cookie keeps you signed in to your MediaMetrix account.
One-pager access cookie lets you download the one-pager again for 30 days after you request it.
Security cookies protect our forms from cross-site request forgery and carry short-lived messages between pages, such as a confirmation after you submit a form.

Analytics and advertising

We use Google Tag Manager to run measurement tools, such as Google Analytics and Google Ads conversion tracking. These tools may set cookies and collect information about how you use our site, such as the pages you visit, how you arrived, your device and browser, your approximate location from your IP address, and whether you submitted a form. We use this to understand how people find and use our site and to measure our advertising. Google processes this information under its own privacy policy, and you can see how Google uses information from sites that use its services.

You can block or delete cookies in your browser settings, opt out of Google Analytics with Google's opt-out browser add-on, or manage ad personalization in your Google ad settings. Our site also loads fonts from Google Fonts, which means your browser connects to Google's servers and shares your IP address with Google when you visit.

We share information only with service providers that help us run MediaMetrix, and only as needed for them to do that work:

Microsoft Azure hosts our website, application and database.
Microsoft and Google handle sign-in if you choose to sign in with them.
Google provides the analytics and advertising measurement tools we run through Google Tag Manager (see Cookies).
Anthropic provides the AI service we use to write report summaries. It receives the report performance data needed to write each summary, not your account password or platform keys.
Email and messaging providers deliver the emails and texts we send.
Your ad platforms (such as Meta, Google and CallRail) receive the requests we make with the access you've given us, under their own privacy policies.

We may also disclose information if the law requires it, to protect our rights or the safety of others, or as part of a merger, acquisition or sale of our business, in which case this policy would continue to apply to your information.

Security and retention

We use encryption in transit (HTTPS) across the site. Platform access keys and tokens are encrypted before they're stored and are never shown again after you save them. Access to form submissions is limited to the MediaMetrix team. No system is perfectly secure, but we work to protect your information and will tell you if a breach affects you where the law requires it.

We keep form submissions and account information for as long as we have a business relationship with you, or as long as needed for the purposes above, and then delete them. You can ask us to delete your information sooner. When you remove a platform connection, we delete its stored access key.

Your choices and rights

You can ask us to access, correct or delete your personal information, or to stop contacting you, by emailing hello@mediametrix.ai. Depending on where you live, you may have additional rights under local law, such as the right to know what we hold about you or to object to certain uses. We'll respond within the time the law requires and won't treat you differently for making a request.

MediaMetrix is a business service and isn't intended for children. We don't knowingly collect information from anyone under 16.

Changes to this policy

If we change this policy, we'll post the new version here and update the date at the top. If a change materially affects how we use your information, we'll let you know before it takes effect.
