StatusThe full bank isn't on sale yet. The parts about buying apply from the day it is.

Who's responsible

Klartext LLC, a Michigan limited liability company, PO Box 153, Lake Ann, MI 49650. Contact: support@klartext.one.

The short version

Klartext has no accounts, no analytics and no ads. Your practice progress stays in your own browser. When you buy, Paddle handles your name, email address and payment details. We keep your order ID and what's needed to unlock the bank, and, if you email us, your email.

When you visit

  • Hosting. Cloudflare hosts klartext.one. To deliver the site, Cloudflare processes technical data such as your IP address. If a page fails to load, your browser may send Cloudflare an error report with your IP address, the address you tried and the type of error. cloudflare.com/privacypolicy
  • Fonts. The site's fonts come from klartext.one itself. Your browser doesn't contact any other service to load them.
  • Theme. If you pick dark or light, your browser keeps that choice in its local storage for klartext.one. It isn't sent to us.

When you use the app

Your answers, flags and mock exam results are saved in your browser's local storage, on your device. They aren't sent to us. Clearing your browser's data for klartext.one deletes them.

When you buy

  • The payment. Paddle processes your purchase as our merchant of record, including your name, email address, billing address and payment details. Paddle's privacy policy covers that data: paddle.com/legal/privacy. Paddle's checkout script loads only on our buy page.
  • What we see. In Paddle's dashboard we can see your order. We use it only to answer you, reset devices and handle refunds.
  • Marketing. Paddle's checkout asks whether you'd like marketing email, and Paddle records your choice. Klartext hasn't sent any marketing email. Before we send any, we'll update this page to name the email service we use.

When you email us

If you email us, your address and message are kept in our Google Workspace mailbox. Support email is deleted once it's more than 2 years old, in a cleanup we run every 3 months. If we refund you directly, we ask for the payment details needed, use them only for that refund, and keep only a record that the refund was paid. Google's privacy policy: cloud.google.com/terms/cloud-privacy-notice.

When you unlock the full bank

When you enter your order ID, the app sends it to our server with a random ID that your browser makes for itself. Our server keeps, for each order: the order ID, whether it's active, the exam series it covers, the date it was created, the random IDs of up to 5 browsers or devices and the date each one last checked in, how many times they've been reset, references to any refund or chargeback, and, if we refund you directly, the date, amount and method of that refund. A browser checks in when it unlocks and when the app renews its access, about every three weeks of use. It doesn't keep your name, email address or payment details. Your browser keeps the order ID, the random ID and a signed access token.

To stop order IDs being guessed, our server counts unlock attempts from each IP address for about a minute. It doesn't store your IP address with your order.

We keep the order record as long as your access lasts, so the order keeps working.

Your rights

To ask about your data or have your order record deleted, write to support@klartext.one. Deleting the record ends access to the full bank.
