Privacy Policy

The data we collect

User accounts

All the data of your account is yours. When you create your account, we ask information like your email, you name or what company you work for. All this information is used to personalize your experience or send you onboarding emails and invoices. This basic information about your account is only accessible to the team and will never be shared with third parties.

Sensitive data that results from your use of the product like the searches you do on Hunter, the files you upload or the data accessible via connected applications will only be accessed by the team with your permission to help you with a problem or squash a software bug.

The data we distribute in our service

Hunter crawls the entire web and indexes all the email addresses it can find. All the email addresses can be directly distributed in the service with an indication of the place they have been found ("sources"). They can also be used in our algorithm to guess other email addresses.

There are some cases where we don’t collect or distribute these email addresses:

  • Our crawler follows the robots.txt files. Commonly used for search engines, robots.txt files are used on a website to indicate what pages should be read or not by crawlers. In clear, if a website owner doesn’t wish some pages to be read, we don’t.
  • We never distribute webmail email addresses, like Gmail or Yahoo. Hunter is designed for professional use only.
  • Whenever a professional asks for his information to be removed from our database with the Claim functionality.

Browser extension

Hunter’s browser extension on Chrome and Firefox lets you use our services directly through your browser. While you use the browser extension, it collects the domain names visited in an anonymized fashion. This statistical information helps us identify the most popular websites and improve the service.


Hunter edits another extension, MailTracker. MailTracker lets you track the emails you send with Gmail. The extension integrates into Gmail and needs to connect to your Google account. We store the recipients, the senders, the objects and the dates of the email addresses.

This data is used for the purpose of the email tracking and also helps us to validate the email addresses in the database distributed in Hunter's services. We use the MailTracker information to verify email addresses, update their confidence score, verify the names associated and better detect the email patterns. The data collected with MailTracker is only used for verifications but never to enrich the database distributed in Hunter's services.

Google Sheets Add-on

The Google Sheets Add-on only modifies your Google spreadsheets to return email addresses. It never modifies them unless you ask to do so by launching an enrichment. It never stores any information contained in your spreadsheets.


In all our products, we may track actions done by our users to improve the service. We'll track these actions for statistical purposes, for example, to know the popularity of a feature or the conversion rate of a page. This data is only accessible to the team.

Your Controls and Choices

You can access, change or delete your personal information at any time in your dashboard, or if it’s not directly possible, by contacting our support team.

If a professional email address you own is distributed in our services, you can modify or delete the data related to this email address we collected by using the Claim functionality.


The security of your personal information is important to us. We maintain a variety of appropriate technical and organizational safeguards to protect your personal information.

All data is encrypted via SSL/TLS when transmitted from our servers to your browser. We work with security researchers to continuously improve the overall security of Hunter. We go to great length to secure your data. You can read more in our Security Policy.


We use cookies to recognize you when you're using our services and give you the best possible experience. Learn more about how we use cookies in our Cookie Policy.
