Privacy & Terms

No ads or cookies. Without an account, your progress and your officials are saved only in this browser, on this device. Looking up your officials by ZIP code happens on your device too: the ZIP code isn’t sent anywhere or saved, only your state and congressional district, with your officials.

Signing in is optional. If you sign in (with your email and a 6-digit code we send you; no password), we store your email address, a copy of your learning (progress, vocabulary, badges, bookmarks, officials and practice results) so it’s the same on all your devices, your signed-in devices (the device type only, like “iPhone”), and when you last used the app. No names or IP addresses. An unlock code you add is stored with your account. Delete your account any time in Settings: it’s erased from our server right away, and we email you any unlock code that was on it. Accounts unused for 3 years are deleted, after an email warning 30 days before.

To improve the app, we count visits anonymously: which sections are opened, whether practice tests, interviews and vocabulary games are started and finished, whether sharing is used (not what or with whom), your device type, language and approximate area (country and U.S. state). There’s no ID, so visits can’t be linked to each other or to you. No IP address is stored. Raw counts are deleted after 90 days. Turn it off any time in Settings; if your browser asks sites not to track you, nothing is sent.

If you send feedback, only what you write (and your email, if you give one) is stored, so we can improve the app. We don’t collect your IP address or anything else about you.

If you share your story, we store what you write, the name and state you choose to show (both optional), your translation language, whether you passed the USCIS interview or 3 practice interviews, the month, and a random ID made only for the story, so you can update or remove it. No email or IP address. It appears on the website only after we review it. Remove it any time in Settings, or email help@n400practice.com. If you report someone’s story, we store only the reason you picked and the time, nothing about you. Stories you hide stay hidden on this device only.

Bookmarks (“Often forget”) stay on this device. If you choose to share them, each time you add or remove one we store a random ID for this device (not linked to you), your approximate area (country, state, and the first 3 digits of the ZIP code, estimated from your connection), your device type and language setting, the time, the question number, where in the app you were, and whether you’d just answered it right or wrong. No name, email, IP address, or exact location. It’s used only to count how many people bookmark each question for the “Most forgotten” list. Raw records are deleted after a year (monthly totals per question are kept). You can stop sharing and delete what you shared any time in Settings.

Mock interview results can be shared too, only if you choose to (you’re asked once, after your first finished interview). We store the scores, never what you said or typed: which civics questions and reading and writing sentences were asked and whether you got them right (and how close you got), how often you asked the officer to repeat or explain, how long each part took, whether you spoke, typed, or tapped, and where you stopped if you didn’t finish. They’re linked to the same random device ID and details as shared bookmarks (approximate area, device type and language, the time). The language is the study translation you chose, if any, otherwise your browser’s language. Your answers to questions about you, your yes/no answers, and the AI officer’s note are never sent. Raw records are deleted after a year (monthly totals are kept).

If you buy a coffee, Stripe processes the payment. The site never sees your card; the owner receives your name, email and any message from Stripe.

If you buy the unlock, we store your unlock code, what you bought and paid, the email Stripe gives us (to send your code and for refunds), any promotion code you used, and up to 3 random device IDs that aren’t linked to you. No names, card details or IP addresses. Stripe processes the payment under its own privacy policy. Email help@n400practice.com to have this deleted; that switches the unlock off. If you buy in the iPhone or iPad app, Apple sends us the purchase details (product, price and a transaction ID, not your name or card), which we store with your code; an email address is stored only if you enter one to receive your code. For organizations that buy seats, we store the organization’s name, its contact email, the seat codes and whether each one is in use, not who uses it. A tax ID given at checkout stays with Stripe.

The optional AI officer in the mock interview runs on your device. Your answers to it are never sent anywhere. Only the model file itself is downloaded, once, from models.n400practice.com (or Hugging Face as a backup).

What’s free: 30 Study questions (and reviewing them), 2 practice tests, 3 rounds each of the English reading and writing practice, 30 English speaking questions, and the start of the mock interview. People who used the app before October 2026 keep Study, practice tests and English practice free. The unlock opens everything (all 128 questions, unlimited practice tests, English practice, and AI Interview, the mock interview including the AI officer) for a one-time purchase: $29.99 for one person, on up to 3 of their devices, or $49.99 for a family pack of 3 codes. Access doesn’t expire. Prices are in US dollars, plus sales tax where it applies.

Pass or your money back: if you don’t pass your civics test, email help@n400practice.com within 120 days of purchase and we’ll refund what you paid, minus Stripe’s card fee (about $1.17 on $29.99). No questions asked. A refund switches the code off.

Codes: each code works on up to 3 devices. To use it on a new one, the app emails a confirmation link to the purchase email, and the device used longest ago stops being unlocked. Please don’t post codes publicly; shared codes may be switched off. Free codes from us (for reviewers and partners) have no refund.

App Store purchases (in the iPhone and iPad app): Apple processes the payment and handles refunds under its own policies. Your code works on n400practice.com and other devices too (up to 3 per code). The money-back guarantee applies to purchases made on n400practice.com.

Organization seats: $12 a seat, for one learner on up to 3 of their devices, bought 50–500 at a time by card, or by invoice for larger or custom orders. Unused codes never expire. Unused seats can be refunded within 30 days of purchase, minus Stripe’s card fee; seats already in use can’t be refunded. The pass guarantee is for individual and family purchases, not seats. The organization can replace unused codes and reset a code’s devices on its page.

Stories: stories on the website are the experiences of the people who wrote them, shown as written after a review for spam and personal details. No hateful, sexual, violent or abusive content: stories that break this are removed. Anyone can report a story (it’s hidden for everyone until we review it) or hide it on their own device. Nobody is paid or rewarded for one. Everyone’s experience is different, and passing a practice interview here doesn’t mean you’ll pass the USCIS interview.

This is a practice tool, not legal advice, and it can’t promise how your real interview goes. Payments are processed by Stripe. Questions or refunds: help@n400practice.com.
