Visiting the site

Our hosting provider, Vercel Inc. (USA), processes technical data from each request (IP address, browser, page, date and time) to deliver and protect the site. We derive your country from the IP address to show the right currency and price; we do not store it. Legal basis: legitimate interest (Art. 6(1)(f) GDPR).

Tests and practice

Your answers, scores and the texts you write in Pisanie stay in your browser (localStorage) and are not sent to us.

Your account

Sign-in and accounts are provided by Clerk, Inc. (USA). We process your email address, your name if you give it, and session data to run your account and unlock what you bought. If you buy without signing in, we create the account with the email used at checkout or attach the purchase to the existing account with that email. Legal basis: performance of a contract (Art. 6(1)(b) GDPR).

Payments

Payments are handled by Stripe (Stripe Payments Europe Ltd., Ireland, and Stripe, Inc., USA). Card details go straight to Stripe; we never see them. We receive name, email, country, product, amount and payment status. Legal basis: contract and legal obligations (Art. 6(1)(b) and (c) GDPR).

Emails

Purchase confirmations are sent through Resend, Inc. (USA). Legal basis: performance of a contract.

Cookies and local storage

We use no analytics or advertising cookies.

  • Clerk cookies (for example __session, __client_uat): keep you signed in.
  • polskib1-theme, polskib1-result-* and polskib1-draft-* in your browser’s local storage: theme, last scores and Pisanie drafts.

Transfers outside the EU

Several providers are in the USA and Polski B1 Prep is operated from Brazil. Transfers rely on adequacy decisions such as the EU-US Data Privacy Framework or on the EU Standard Contractual Clauses.

Retention

  • Account: for as long as it exists; deleted when you ask.
  • Purchase data: as long as tax law requires.
  • Messages to support: as long as needed to answer.

Your rights

Under the GDPR you can ask for access, rectification, erasure, restriction and portability, and object to processing based on legitimate interest. You can complain to a supervisory authority, in Poland the President of UODO.
