Effective October 29, 2026
The short version. Stack42, LLC does not collect, store, or share any personally identifiable information beyond the information provided when an account is created. Everything we hold is confidential to Stack42, LLC and is never shared with any other entity for any purpose, and never for advertising. What our logs and alerts contain stays between Stack42, LLC and you. The one exception is a law enforcement request made by subpoena or warrant, which we will comply with and tell you about within 30 days unless we are prohibited from doing so.
Who we are
Stack42, LLC ("Stack42", "we", "us") is a Kansas company that makes MeerKat: MeerKat Sensors, the devices placed on a customer's network; MeerKat Sentries, the decoy files, links, and QR codes a customer places on their own systems; and the MeerKat Portal, the website where customers see what their Sensors and Sentries detect and choose who is alerted. This policy covers MeerKat, the Portal, and this website.
The information we collect
We collect personally identifiable information only from what is provided when an account is created or kept up to date afterward:
- your company's name, its primary email address, and its primary phone number;
- for each person with a Portal account, their name, email address, and role, and their phone number if they choose to add one; and
- whether each person, and the company's primary contact, has allowed text messages.
We do not buy information about you, we do not collect it from other sources, and we do not build profiles of the people who use MeerKat.
Logs and system alerts
To do its job, MeerKat records activity aimed at your Sensors and Sentries: for example, the network address and hardware address of a device that probes a Sensor, when it happened, and what it tried. The Portal also keeps the logs any secure system needs, such as sign-ins, changes to settings, and the network address each request came from. Alerts we send you by email or text describe that same activity.
Everything in our logs and system alerts is confidential. It is kept in the strictest confidence and remains internal to Stack42, LLC and to you, the client it belongs to.
How we use information
We use the information we hold only to provide MeerKat to you: to run your account, to detect and report activity on your network, to send the alerts you choose, to answer your support requests, and to keep the service secure.
We never share it
Any information we collect is confidential to Stack42, LLC. We never sell, rent, trade, or share it with any other entity for any purpose, and we never use it for advertising, ours or anyone else's.
Delivering a text alert requires handing the message and your mobile number to the text messaging service that carries it (Twilio), and to the mobile carrier that delivers it. They receive only what is needed to deliver that one message and may not use it for anything else. No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. Text messaging opt-in data and consent are never shared with any third party.
Law enforcement requests
The only exception to the rules above: Stack42, LLC will comply with a law enforcement request for information made by subpoena or warrant. When we receive one, we will notify the affected client within 30 days, unless law enforcement or the law prohibits us from doing so.
Text messages
MeerKat sends text messages only to people who have allowed them, and only the alerts their company's Admins have chosen. Message frequency varies with what your Sensors detect. Message and data rates may apply. Reply STOP to stop receiving texts, or HELP for help. You can also turn off Allow SMS on your Account settings in the Portal at any time.
Cookies
The Portal uses only the cookies it needs to work: one that keeps you signed in, and two that protect signing in (one ties an emailed sign-in link to the browser that asked for it, and one guards the sign-in form against forgery). We use no advertising or tracking cookies, and this website sets no cookies at all.
How we protect it
Information is stored on servers we manage. Connections to the Portal and from Sensors are encrypted, access inside Stack42, LLC is limited to the people who need it to support you, and staff actions in the Portal are recorded.
How long we keep it
We keep account information for as long as your account is open. When an account is closed, ask us and we will delete its information, except for anything the law requires us to keep.
Your choices
Each person can see and change their own name, phone number, and text message setting under Account settings in the Portal. Your company's Admins can add and remove people. To see, correct, or delete anything else we hold, email info@stack42.net.
Children
MeerKat is a business service. It is not intended for children, and we do not knowingly collect information from anyone under 13.
Changes to this policy
If we change this policy, we will post the new version here with its effective date, and tell account holders by email before a change that affects how their information is handled takes effect.
