Who we are
OperadorListo is independent practice software for the Texas Class D Water System Operator exam. Based in Florida, USA. Contact: hola@operadorlisto.com. Mailing address: OperadorListo · 3000 Biscayne Blvd, Suite 210A PMB1086, Miami, FL 33137, USA.
What we collect
- Your email address, if you type it in to get a free guide by email (see “Free guides by email” below), when you start the free week or pay through our payment provider.
- The free check and the sample question: whether you answered each question right or wrong, its area, and your score. No name and no email.
- Your account (members only): the email and the name you entered at Stripe checkout (we use the name only to greet you in the app and in our emails), your practice progress (questions answered, right or wrong, and scores by area), your practice exam results, your exam date if you give it to us, and a daily count of your AI tutor messages (the messages themselves go to our AI provider to write the reply and aren’t saved).
- Visit and campaign data: the UTM tags in the link you clicked (for example
utm_sourceorutm_campaign), whether you arrived from a Facebook ad click (yes or no only; we don’t store the click ID), the website that sent you (without its query string), the page language, a random session ID and the time. - Funnel events: page views, the sample question, starting and finishing the free check, each question answered (right or wrong), and tapping the free-week button.
- App activity (members only): which parts of the app you use (opening the app, starting practice, a practice exam, opening the AI tutor), with counts and scores only, the random session ID and a code for your account that doesn’t contain your name or email. Never the text of a question, the option you picked or anything you type.
We don’t ask for your phone number, home address, license number, or anything about ethnicity, national origin, immigration status, union membership or income. The only name we keep is the one you enter at checkout. We don’t send marketing text messages.
Payments
The OperadorListo free week and monthly plan are sold through Stripe. Stripe collects your payment details under its own privacy policy, also when you choose another payment option at checkout, such as Apple Pay (those providers have their own policies too). We never see or store your full card number. We receive your email, the name you entered at checkout, the amount, your subscription ID, a random reference ID that links the purchase to your visit and, when Stripe records it, that you ticked the terms box. We never put personal data in links.
Free guides by email
On some free pages you can ask us to email you the guide. Then we keep only your email address, the page language, which guide you asked for, that you agreed to the line next to the box, a random visit ID and your browser’s user-agent string. No name and no phone number. The guide is always complete on the page: the email is only a copy.
We send the guide right away, and it is the only email from that box. It has an unsubscribe link. We keep this data for up to 24 months.
The member area
- Your account: we create it from the email you used at Stripe checkout.
- Signing in: there’s no password. We email you a sign-in link at the address on your account.
- Login cookie: when you sign in, we set one cookie that keeps you signed in on that device for 30 days. The member area needs it to work, and we don’t use it for ads.
- Your progress: your practice history, progress by area and practice exam results are stored in our Cloudflare D1 database in the United States, so you can pick up where you left off on any device.
The AI tutor
The AI tutor is for people 18 and older. When you tap “Explain this” and ask something, we send the question you typed and the text of the practice question to Anthropic, the company that makes the Claude model, to write the reply. We don’t save your tutor chats: they’re gone when you close the tutor. We only keep a daily count of your messages, for the 40-a-day limit. Our AI provider doesn’t use these messages to train its models. Please don’t type personal information into the tutor. The tutor is software and can be wrong; check the source it points to.
Cookies and browser storage
The public pages don’t set cookies of their own. For your visit they keep a random session ID and the link’s campaign tags in your browser, and on your device two settings: your language and whether you have signed in as a member on that device. The member area sets the login cookie described above, and keeps your language and a copy of your latest work in your browser until it’s saved, so a dropped connection doesn’t lose it. You can clear all of this in your browser settings.
To stop abuse, such as too many sign-in attempts, we keep a scrambled code made from your IP address or email for about 2 days, never the address or the email itself.
Do Not Track signals
We don’t track you across other websites, and we don’t let other companies do it on ours. So we treat every visit the same way, whether or not your browser sends a Do Not Track or Global Privacy Control signal.
How we use it
- To give you access to OperadorListo, sign you in, save your progress and run the AI tutor.
- To send your account emails: sign-in links, your progress, the reminder before the first charge, the yearly reminder of your plan and your receipts, and a free guide when you ask for one.
- To see which pages work, and to improve the free check and the practice questions.
- To reply when you write to us, and to meet legal and tax obligations.
Where it’s stored and who helps us
The site runs on Cloudflare, and your data is stored in a Cloudflare D1 database in the United States. Service providers that process data for us: Cloudflare (hosting, database, email sending), Stripe (payments), Anthropic (AI tutor), Google (our work email).
We don’t sell your data
We don’t sell or rent your personal information, and we don’t share it with others for their own marketing.
How long we keep it
We keep visit and free-check data for up to 24 months after your last visit, your progress for as long as your account exists, payment records for as long as tax and accounting rules require, and the record of when you started the free week (the terms we showed you and that you accepted them) for at least 3 years, or 1 year after your plan ends if that is later, as California law requires. You can ask us to delete the rest sooner.
Your choices and rights
- Every progress or marketing email we send has an unsubscribe link. Sign-in links and receipts are sent only when you need them.
- Write to hola@operadorlisto.com to see, correct, export or delete your data. We reply within 45 days. If we say no to a request, you can reply to appeal and we’ll review it again.
- We honor these requests for everyone, wherever you live. Some states’ privacy laws give you these rights too, where they apply.
Children
OperadorListo is not for children under 13, and we don’t knowingly collect their data. If you think a child under 13 gave us information, contact us and we’ll delete it.
Security
We use HTTPS, limit who can access data, and work with established providers. No system is perfectly secure, so please don’t send us anything you don’t need to.
Changes and contact
We may update this policy and will post the new date at the top. If a significant change affects members’ data, we also email them. Questions or requests: hola@operadorlisto.com.
