Privacy

Last updated October 11, 2026

In short

• We collect only what we need to run CDL Coach: how to sign you in, your study progress and your purchases.
• We never sell your data, we don't show ads and we don't use advertising trackers.
• You can ask us to delete your account and data at any time: support@cdlcoach.ai.

What we collect

• Sign-in: the email address or phone number you enter to receive a one-time code. The code is delivered by our messaging provider (Twilio). We store a one-way fingerprint of your email or phone to recognise you next time. If you buy study access for someone else and send it to them, we also store the invited email or phone and the optional name, to manage that invitation.
• Study progress: your answers, which questions you have mastered, saved or need to review, hints used, your exam results, your difficulty level and your chosen state, tests and language.
• Purchases: the plan, amount, date, any discount code and the payment status. Payments are handled by Stripe, which receives your card details; we do not.
• AI coach: when you ask the coach a question, your message, the recent conversation and the question on screen are sent to the AI model provider that runs the coach to write the answer. We don't save coach conversations to your account; we count how many messages you send each day to apply the daily limit.
• On your device: the app stores your settings (appearance, language, state) and, if you are not signed in, your progress in your browser's local storage. Sign-in uses one secure cookie.
• Mistake reports and emails you choose to send, including the test results you send for a claim.
• Usage counts: to see where learners get stuck, the app counts a few steps: opening the app, finishing the first-run questions, the first answer, finishing a practice or exam (its type and a score range such as 80–89%), reaching the end of the free preview, opening checkout, starting and finishing sign-in (email or text message), completing a purchase, changing the language and opening the coach. Each count carries only the state, the language and a random device ID that your browser makes; the ID is not linked to your account, email or phone.

Why we use it

To sign you in, save and sync your progress, check answers, give you access to what you paid for, answer coach questions, handle refunds and the pass promise, answer your messages, keep the service secure and fix problems. We don't use your data for advertising and we don't sell or rent it.

When someone else pays

Accepting study access that someone else bought links your account to that person. Before you accept, we explain that they can see your study progress and exam results. Your answers and saved questions stay private. They keep the purchase, payment and refund records; the study access belongs to your account, and your existing progress is kept.

Who we share it with

Only the providers that run CDL Coach for us, under contract and only for that purpose: Stripe (payments), Twilio (sign-in codes), Cloudflare (website delivery), our hosting provider and the AI model provider behind the coach. We may disclose information if the law requires it.

How long we keep it

Account and progress data are kept while your account is active and deleted when you ask us to delete your account. Purchase records are kept as long as tax and accounting law requires. Individual usage counts are deleted after 90 days; only daily and weekly totals are kept after that.

Your choices

You can use CDL Coach without signing in; your progress then stays on your device. To stop usage counts, turn on Do Not Track or Global Privacy Control in your browser; resetting progress in Me also replaces the device ID. You can ask us for a copy of your data, to correct it, or to delete your account by emailing support@cdlcoach.ai from the email or phone you sign in with. Residents of some states, such as California, have additional rights under state law; we honour them the same way.

Children

CDL Coach is made for people preparing for a commercial driver's license and is not directed at children under 13. We don't knowingly collect personal information from children under 13; if you believe we have, email us and we will delete it.

Security

Data travels over encrypted connections, sign-in codes expire quickly, and access to member data is limited and logged.

Changes and contact

We'll post any changes here and update the date above. Questions: support@cdlcoach.ai.
