Terms of Service

Last updated: October 8, 2026

These terms govern your use of digitalchk.com and the free tools published on it. They are written to be read, not to be survived. If something here is unclear, write to us and we will explain it in plain words.

Who you are agreeing with

Digital Checkmark LLC, an IT and cybersecurity services company based in Tampa, Florida, United States. In these terms, “we” and “us” mean Digital Checkmark LLC, and “you” means the person or organization using this website.

By using this site or any tool on it, you accept these terms. If you do not accept them, please do not use the site.

What these terms cover

This page covers the website, the free tools and the fair use of Chatbot Chk, our WordPress plugin. It does not cover our paid services. Managed IT, security, continuity and any other engagement is governed by the written agreement signed for that work, which takes precedence over anything on this page.

Each free tool also shows its own specific terms at the point where you use it, describing what that tool queries and what it stores. Those tool specific terms apply in addition to these, and where a tool’s terms are more specific, the tool’s terms govern that tool.

The free tools

What they are for

The tools exist to give you a straight answer about something concrete: whether an address appears in a known breach, whether a domain’s email authentication is configured correctly, whether a message shows the markers of phishing, and so on. They produce information. They do not produce decisions, and they are not a substitute for professional judgment applied to your situation.

Nothing a tool returns constitutes legal, regulatory, financial or professional security advice, and a result should not be the only basis for an important decision.

Use them only where you are allowed to

You may use the tools for lawful purposes, on domains, addresses and messages that you own or that you are authorized to assess. Do not use them to profile, probe or gather information about people or organizations without a legitimate reason to do so.

You also agree not to:

• Automate, script or scrape the tools, or use them at a volume that a person could not reach by hand
• Circumvent the anti-bot check, the email verification step, or any usage limit
• Resell the tools or present their output as your own product
• Attempt to reach parts of the site or its infrastructure that are not published
• Use the tools in a way that breaks the terms of the upstream data sources named in our privacy policy

We can restrict or block access that breaks these rules, and we do not owe an explanation before doing so when the traffic is clearly abusive.

Accuracy, and what we cannot promise

The tools depend on data that belongs to other people. Breach records, ransomware victim disclosures, URL reputation and public DNS all come from outside sources that we do not control and cannot correct. A result can be incomplete, out of date, or wrong, and the absence of a finding is not proof that nothing is wrong.

We are also explicit about one thing that is easy to misread: a tool reporting no problem means the tool found no problem with the checks it performed. It does not mean you are secure.

Reports written with AI

Some reports include an explanation and an action plan written by an AI model from the technical findings. These are labeled as such. Any DNS record a report suggests carries a warning to validate it before publishing, and that warning is there because it is meant seriously: a wrong DNS record can stop your mail from being delivered. Check every suggested value against your own configuration before you apply it, or ask someone who can.

The chat

The chat on this site answers with an AI model that reads our own pages. Its answers are there to help you find information, and they can be wrong or incomplete: they are not a quote, a commitment or professional advice, and prices and conditions are only the ones a person from our team confirms in writing. Do not share passwords or other secrets in the chat. When you ask for a person, someone from our team reads the conversation and replies there or by email. Please do not use the chat to send spam or for anything unrelated to our services. Our privacy policy explains what the chat keeps and for how long.

Availability

The free tools are offered without any uptime commitment. They depend on outside services, and when one of those is unavailable the tool will tell you so rather than invent a result. We may change, limit or withdraw any free tool at any time.

For our paying clients, availability and response times are defined in their agreement. As a general note, our automated monitoring and containment run continuously, and human response is available from 8am to 8pm Eastern Time.

Chatbot Chk: fair use

What counts. Each answer the bot gives with our AI counts as one message. Messages between a visitor and a person on your team do not count, and neither do answers the bot gives with your own AI key. With your own key there is no limit on our side.

Messages per plan, each month:

• Free: 100.
• Starter: 1,000.
• Pro: fair use up to 20,000, shared by its up to 3 sites.
• Agency: 60,000, shared by its up to 10 sites.
• 14-day Pro trial: 1,000.

A conversation uses about 5 answers on average, so 20,000 messages are about 4,000 conversations.

“Unlimited” on Pro means the normal use of a business website. Almost no customer reaches the limit; if your real traffic needs more, write to us and we raise it at no extra cost.

When you reach the limit. We warn you in the dashboard at 80% and at 100%. The chat does not break: it shows your “not available” message and keeps offering to leave an email and to talk to a person. AI answers come back when the next month starts, or right away if you connect your own key.

Not fair use:

• reselling or sharing access;
• using the chat as an API for other systems;
• sending automated or bulk messages;
• using the AI for anything other than helping the visitors of your site.

There is also an hourly limit against abuse. If we see use like this, we write to you first; only if it continues may we pause the AI answers of that license.

What counts as a site. Each site on a license is one WordPress with the plugin. If that WordPress runs the chat on another domain (a Wix, Shopify or plain HTML site, for example), that domain is the site: the chat answers only there. Each additional domain needs its own WordPress and its own place on a license.

Changes. If we change these numbers, we give 30 days’ notice, and a change never applies in the middle of a period you already paid for.

SMS messaging terms

These terms apply if you receive text messages from us.

• Program. Digital Checkmark LLC sends service notifications by SMS: support ticket updates, appointment reminders, security alerts, account activity notices and service outage notifications. This is not a marketing program and we do not send promotional texts.
• Consent. We message only numbers whose owner agreed to receive them, through a signed services agreement, a form on this site with the SMS consent box checked, a reply of YES or START, or a written request to our team. Consent to receive SMS is never a condition of buying anything from us.
• Frequency. Varies with your service activity, typically one to five messages per month.
• Cost. We do not charge for these messages. Message and data rates may apply, and are set by your carrier.
• Stopping. Reply STOP to any message and we stop immediately, with one confirmation. Reply HELP for contact information. You can also email [email protected].
• Carriers. Mobile carriers are not liable for delayed or undelivered messages.
• Your data. Your number and consent record are handled as described in our Privacy Policy. We do not share or sell mobile opt-in data or phone numbers to third parties for marketing or promotional purposes.
• Devices and areas. Delivery depends on your carrier and device, and we cannot guarantee either.

Using a tool does not make us your provider

Running a free tool, receiving a report, or writing to us does not create a client relationship, a retainer, or any duty of care beyond what is described here. A working relationship begins when both sides sign an agreement for specific work.

Your content

When you submit something to a tool, such as an email file for analysis or a domain to check, you keep ownership of it. You confirm that you have the right to submit it. We use it to produce your result and, as described in our privacy policy, we keep the full analysis for no more than 2 hours, only to build your summary and report, and do not retain the content of analyzed messages after that.

Our content

The text, design, code, articles and tools on this site belong to Digital Checkmark LLC, except where a third party is credited. You may read, quote and link to our articles with attribution. You may not copy the tools or republish substantial parts of the site as your own.

The reports a tool generates for you are yours. Use them, share them internally, give them to your auditor.

Limitation of liability

The free tools are provided “as is” and “as available”, without warranties of any kind, whether express or implied, including any implied warranty of merchantability, fitness for a particular purpose, or accuracy.

To the maximum extent the law allows, we are not liable for indirect, incidental, special or consequential damages arising from your use of this site or the free tools, including lost profits, lost data, or business interruption. Where liability cannot be excluded, it is limited to one hundred dollars (USD 100) for matters relating to the free tools.

This section does not limit liability for fraud, for willful misconduct, or for anything that cannot lawfully be limited. Nor does it affect the terms of a signed services agreement, which has its own provisions.

Links to other sites

We link to outside references, documentation and data sources. We do not control those sites and are not responsible for their content or their practices.

Changes

We may update these terms. When we do, we will change the date at the top of this page. If a change materially affects how the tools may be used, we will say so plainly rather than editing the text quietly. Continuing to use the site after a change means you accept the updated terms.

Governing law

These terms are governed by the laws of the State of Florida, United States, without regard to conflict of law rules. Any dispute relating to this site or the free tools will be brought in the state or federal courts located in Hillsborough County, Florida.

If any part of these terms is found unenforceable, the rest remains in force.
