Privacy Policy

June 17, 2023

We value your privacy.

Information We Collect

When you use our service, you share information with us:

As you use our services, we want you to be clear how we use the information you share with us. Please take the time to get to know our practices, and contact us if you have any questions.

eMail addresses

Many of our tests focus on email, so we see a lot of email addresses. We will never share individual personal information without your consent or unless ordered by a court of law. We will never share, sell, or rent any email addresses we collect as part of testing done at CheckTLS unless ordered by a court of law.

Authentication information

Some of our tests allow you to supply authentication information such as user ids, passwords, ssh keys, private IP addresses, and other access credentials. We do not save this information, but we cannot assure that some of our tools, used in certain ways, could result in such information being captured in our logs.

Log information

When you use our services or view content provided by CheckTLS, we may automatically collect and store certain information in server logs. This may include:

Cookies and anonymous identifiers

We use various technologies to collect and store information when you use CheckTLS. This may include sending one or more cookies or anonymous identifiers to your device.

Google Analytics

We use Google Analytics to track use of our site. As we are focused on furthering email tools and knowledge, we do not have the resources to develop the tools that Google provides for free to help us manage our site. While there is no telling what Google collects or does with your information, they too state they protect privacy, and they already know everything anyway.

How We Use Information We Collect

We use the information we collect from our services to provide, maintain, protect and improve them, to develop new ones, and to protect CheckTLS and our users. We may also use this information to introduce new products, services, and offers tailored to you. We may use the identification you provide for your CheckTLS Subscription across all of the services that we offer. In addition, we may replace past names associated with your CheckTLS Subscription so that you are represented consistently across all our services. When you contact CheckTLS, we may keep a record of your communication to help solve any issues you might be facing. We may use your email address to inform you about our services, such as letting you know about upcoming changes or improvements. We will ask for your consent before using information for a purpose other than those that are set out in this Privacy Policy. CheckTLS may processes information you provide on servers around the world. This includes servers located outside the country where you live.
See our Data Protection Policy for more information about our Information Collection and Retention.

Transparency and choice

People have different privacy concerns. Our goal is to be clear about what information we collect, so that you can make meaningful choices. For example, you may set your browser to block all cookies, including cookies associated with our services, or to indicate when a cookie is being set by us. However, it is important to know that some of our services may not function properly if your cookies are disabled.

You can use our site to access private areas of your systems. You are expressly forbidden from using our site to access any system that you do not have permission to access. We do not deliberately keep any private information, such as login information or private keys. There may be ways of using our tests that result in such private information being captured by our logs. Be careful with what information you provide to us when accessing private areas. We advise the use of temporary passwords and such, and promptly deleting them.

We give you complete access to your Subscription information. If that information is wrong, you can update it or delete it quickly, unless we have to keep that information for legitimate business or legal purposes. When updating your personal information, we may ask you to verify your identity before we can act on your request. Where we can provide information access and correction, we will do so for free, except where it would require a disproportionate effort. We aim to maintain our services in a manner that protects information from accidental or malicious destruction. Because of this, after you delete information from our services, we may not immediately delete residual copies from our active servers and may not remove information from our backup systems.

Information we share

We do not share personal information with companies, organizations, and individuals outside of CheckTLS unless one of the following circumstances apply:

With your consent

We will share personal information with companies, organizations, or individuals outside of CheckTLS when we have your consent to do so. We require opt-in consent for the sharing of any sensitive personal information.

For external processing

We may provide personal information to our affiliates or other trusted businesses or persons to process it for us, based on our instructions and in compliance with our Privacy Policy and any other appropriate confidentiality and security measures.

For legal reasons

We will share personal information with companies, organizations, or individuals outside of CheckTLS if we have a good-faith belief that access, use, preservation or disclosure of the information is reasonably necessary to:

In Aggregate

We may share aggregated, non-personally identifiable information publicly and with our partners, e.g. publishers, advertisers, or connected sites. For example, we may share information publicly to show trends about the general use of our services. If CheckTLS is involved in a merger, acquisition, or asset sale, we will continue to ensure the confidentiality of any personal information and give affected users notice before personal information is transferred or becomes subject to a different privacy policy.

Your choice regarding your personal information

You have the option of not providing us the Personal Information at the point where it is collected. This may result in unavailability of certain services to you. For example, we require a Subscriptioni with a small number of mandatory fields to use some services. If you elect not to provide the requested information, you might be not be able to subscribe and use all of our services.

Information security

We work hard to protect CheckTLS and our users from unauthorized access to or unauthorized alteration, disclosure, or destruction of information we hold. In particular:


Our Privacy Policy applies to all of the services offered by and its affiliates, including services offered on other sites, but excludes services that have separate privacy policies that do not incorporate this Privacy Policy. Our Privacy Policy does not apply to services offered by other companies or individuals, including products or sites that may be displayed to you in our results, sites that may include CheckTLS services, or other sites linked from our services. Our Privacy Policy does not cover the information practices of other companies and organizations who advertise our services, and who may use cookies, pixel tags, and other technologies.


We regularly review our compliance with our Privacy Policy. When we receive formal written complaints, we will contact the person who made the complaint to follow up. We work with the appropriate regulatory authorities, including local data protection authorities, to resolve any complaints regarding the transfer of personal data that we cannot resolve with our users directly.


Our Privacy Policy may change from time to time. We will post any privacy policy changes on this page and, if the changes are significant, we will provide a more prominent notice (including, for certain services, email notification of privacy policy changes).

Key terms

Personal information
This is information which you provide to us which personally identifies you, such as your name, email address or billing information, or other data which can be reasonably linked to such information by CheckTLS.
CheckTLS Subscription
You may access some of our services by signing up for a CheckTLS Account and providing us with some personal information (typically your name, email address, and a password). This account information will be used to authenticate you when you access CheckTLS services and protect your account from unauthorized access by others. You can edit or terminate your account at any time through your My CheckTLS dashboard.
A cookie is a small file containing a string of characters that is sent to your computer when you visit a website. When you visit the website again, the cookie allows that site to recognize your browser. Cookies may store user preferences and other information. You can reset your browser to refuse all cookies or to indicate when a cookie is being sent. However, some website features or services may not function properly without cookies.
Anonymous identifier
An anonymous identifier is a random string of characters that is used for the same purposes as a cookie on platforms, including certain mobile devices, where cookie technology is not available.
IP address
Every computer connected to the Internet is assigned a unique number known as an Internet protocol (IP) address. Since these numbers are usually assigned in country-based blocks, an IP address can often be used to identify the country from which a computer is connecting to the Internet.
