Last updated 9 October 2026

StudyPal English (app.studypal.store) helps you learn English phrases. We collect only what the app needs to work, we don't sell your data, and we don't use advertising or tracking tools.

What we keep

  • Your account: your phone number and/or email, your name, and a scrambled (hashed) version of your password. We never see or store the password itself.
  • Purchases: which books you bought, the amount, and the bank reference from your payment slip, so we can unlock your books and help if something goes wrong.
  • Your learning: which phrases you have read, your quiz scores and stars, your streak, and your badges and certificates.
  • Your devices: a name for each device you sign in on, its browser type and country, so we can enforce the 3-device limit and let you sign devices out.

Cookies and storage on your device

We use one sign-in cookie to keep you signed in, and your browser's storage to remember your settings and any progress made while offline. There are no advertising or analytics cookies.

AI checking of your answers

In the “Say it yourself” quiz questions, the English answer you type is sent to OpenAI to check how well it says what you meant. We send only your answer, the phrase from the book and the situation, never your name, phone number, email or account details. OpenAI processes it under its API data policies. We keep only the result (for example “understood” or “check your grammar”), not the text you typed. Please don't type personal details into your answers.

Who stores it

  • Vercel (USA): runs the website and the app's server.
  • Neon (USA): our database.
  • Oracle Cloud (USA): a fast cache for progress and sign-in limits.
  • OpenAI (USA): checks typed quiz answers, as described above.

Data is sent to them over encrypted connections. We share it with no one else, except where the law requires it.

How long we keep it

We keep your account and learning progress while you use StudyPal so your books stay unlocked. Sign-in sessions are deleted 30 days after they end, and devices you haven't used for 30 days are removed.
