Privacy

Last updated 23 October 2026.

In short

What's stored, and where

Your answers, levels, saved questions, game results and settings (such as light or dark mode) are kept in your browser's local storage on this device, so the app can pick up where you left off. They stay there until you clear them, your browser clears them, or you delete them below.

In the iPhone app, the evening reminder is off until you turn it on. It's set on your phone as a local notification, so nothing about it is sent to us or through Apple's push service.

If you create an account

We store your email address, a username if you choose one, when you signed up, and your active sign-ins (with the IP address and browser they came from, to help you and us spot misuse). Signing in with Google or Apple also gives us the name and email address on that account, and Google also the link to its profile picture (more below). We also keep a list of the new questions you've been given, to count the daily limits and let you see them again. Sign-in codes are emailed through Cloudflare, and so is one notice a few days before free access from a code ends, and one note when we give your account Premium as a gift. We send no newsletters or marketing email. A signed-in session lasts up to 60 days, kept by one cookie that the site's own scripts can't read.

While you're signed in, your progress is also stored on our server so every device you sign in on has the same: your answers (question type, level, whether you got it right, how long it took), your levels, the mistakes waiting for review, the questions you saved for later, game results, and settings such as timed-mode limits. Light or dark mode stays on each device. Nothing from before you signed in on a device is uploaded until you sign in there.

We look at accounts' activity to see how preplaud is used and to fix problems: for each account, its plan, when it was last used, how many questions and games it has synced, and which kinds it practises most. Only preplaud's administrators see this, on a page behind its own sign-in.

If you take the daily challenge, we store your answers, score and time for that day. Each day's leaderboard lists only people who turned on "Show me on daily leaderboards", by username; anyone who can open the site can see it. Everyone else is counted in the total but not named.

Delete your account on the account page: it removes the account and everything stored with it on our server, including your synced progress, straight away.

Signing in with Google

If you choose "Sign in with Google", we ask Google only for your basic profile: your name, your email address, whether Google has verified that address, and the link to your profile picture. We use the email address to find your account and sign you in, and keep the name and picture link with your account; we don't show the picture or use any of it for anything else. We get no access to your Gmail, contacts, Drive or anything else in your Google account. We don't sell this data, share it, or use it for advertising, and deleting your account removes it. preplaud's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

If you report a problem

If you report a question or a username, we store what you reported, the reason you chose and any note you wrote, and, if you're signed in, which account sent it. We use it to look into the problem and fix it.

Usage counts

To see how the site is used, the app sends short, anonymous notes: that it was opened, that a question of a given type was answered (for example "practice, number series"), that a game was played, which named test the home page was set to put first, what you said you're preparing for on the first screens of a first visit (and which test, and how far through those screens you went), that a guide was opened, whether it was read step by step or on one page, and whether it was read to the end, or that a limit of your plan was reached (such as the end of a guide's free part, the top free level or the day's questions) and whether the link there was pressed. Our server adds whether you're signed out, on the free plan or paying, and a visitor code made from your IP address, browser and the date with a secret key. The code can't be turned back into your address and changes every day, so it lets us count daily visitors without a cookie and without linking your visits across days. Your IP address itself isn't stored with the counts. They're kept by Cloudflare Analytics Engine for about three months.

Product analytics and session replays (PostHog)

We also use PostHog, a product analytics service, to see how people find their way around the site and where it gets in their way. While you use the site, it notes the pages you open, the usage notes above, when the coach answered you, a completed purchase, and errors that happen in your browser (what went wrong and where in our code). It also keeps a session replay of the visit: what the page showed and where you clicked and scrolled, so we can play it back. Anything you type is hidden in session replays, and so is everything on the account page, your name and email in the menu, and your conversation with the coach. Each note carries your browser and device type, screen size, the page's address and the site that sent you there.

This goes through our own server to PostHog, so your browser never contacts PostHog itself, and PostHog doesn't get your IP address. Nothing is stored on your device for it, no cookie and nothing in local storage, so if you aren't signed in, each visit is a new visitor and isn't linked to your others. If you are signed in, your visits are linked to your account by its code, along with whether you're on the free plan or paying, so we can see, for example, whether people come back after a week. We never send PostHog your name, email address or username, or anything you type. PostHog keeps this for up to a year, under PostHog's privacy policy. The phone app doesn't use PostHog.

Hosting

The site and its question server run on Cloudflare. To deliver pages and questions, and to protect the site from abuse (for example, limiting how many questions one visitor can request per minute), Cloudflare processes technical data such as IP addresses and browser type, under Cloudflare's privacy policy. This site doesn't use that data to identify you.

We also use Cloudflare Web Analytics, which counts page views and measures how fast pages load. It uses no cookies, doesn't store your IP address and doesn't follow you to other sites.

Payments

Paid access is sold through Stripe, using its Managed Payments service, in which Stripe is the seller. When you press Subscribe you go to a Stripe page, which asks for your payment details, your name and your billing country or address, and may offer you a Link account. We never see or store your card details. When a subscription starts with a free trial, Stripe also tells us the card's fingerprint: a code that identifies the card without revealing its number. We keep it, without your account, so that each card has one free trial. We send Stripe your email address to fill in the form, and Stripe tells us that you've paid: which account, which plan, the subscription's reference and when it renews or ends. We keep that to give you access, and keep purchase records for as long as tax and accounting law requires. Stripe handles your payment data under Stripe's privacy policy. Deleting your account cancels any subscription it has, so you aren't charged again.

The study plan and the coach (AI)

Anyone can make a study plan; it's saved like the rest of your progress. With Premium, a coach changes it when you ask, and explains questions you've answered. The coach uses Claude, an AI model made by Anthropic. When you ask it something, we send Anthropic what you typed, your last few questions and its answers to them, your plan (the test, its date, minutes a day, the drills and your days off) and your record on each drill (your level, how many you've answered, your recent share right, and how many days since you last practised it). When you ask it to explain a question you've answered, we send the question, its answer and our explanation, what you picked, and what you typed. We don't send your email address, your name or your username. Please don't type personal details into the coach.

Anthropic uses this only to write the coach's answer, under its commercial terms, which say it doesn't train its models on it. Under Anthropic's policy for its API, it deletes it within 30 days, unless it's flagged as breaking Anthropic's usage policy (then it can keep it for up to 2 years) or the law requires it to keep it longer; Anthropic's privacy policy says more. We keep your conversation with the coach (your last 12 questions and its answers) with your plan, which is saved and synced like your progress, and, for each account, how much the coach was used each day and each month, to apply its limits.

What allows us to use it

Data protection law in the EU and the UK asks us to say what allows each use of your data.

Where your data is kept

preplaud is run by a company in the United States. Accounts and synced progress are kept in Cloudflare's database in North America, Cloudflare's network delivers the site from servers in many countries, Stripe handles payments in the United States and elsewhere, Anthropic runs the coach in the United States, and PostHog keeps product analytics in the United States. So if you live outside the United States, for example in the EU or the UK, your data leaves your country, and the privacy law where it goes may protect it less than yours does. Cloudflare, Stripe, Anthropic and PostHog move data under the safeguards that EU and UK law set for this: standard contractual clauses and, where it applies, the EU–US Data Privacy Framework. Their privacy policies, linked above, say more.

How long we keep it

Children

preplaud is made for people preparing for job applications. You need to be at least 16 to create an account, and we don't knowingly keep personal data about anyone younger. The coach is for people aged 18 or over. If you think a child has made an account, write to support@preplaud.com and we'll delete it.

Your rights

Wherever the law gives you them (for example in the EU, the UK or California), you can ask us to give you a copy of your data, correct it, delete it, or stop using it, and you can complain to your local data protection authority. You can delete your account yourself on the account page; for a copy of your data, or anything else here, write to support@preplaud.com. We don't sell personal data, and we don't use it for advertising.

Changes

If what we do with your data changes, we'll update this page and its date before the change takes effect.

Who we are

preplaud is run by PREPLAUD LLC, a Wyoming (USA) limited liability company, 30 N Gould St Ste N, Sheridan, WY 82801, USA. For anything about your data, including a copy of it or deleting it, write to support@preplaud.com.

Delete your data

To remove all your progress and settings from this browser, open the privacy page in the app and press "Delete all my data". To delete an account, use the account page.
