LangUp — Privacy Policy

Last updated: 2026-07-26

LangUp (“the extension”, “we”) helps you save words from web pages into your personal LangUp vocabulary and study them later. This policy explains what the extension collects, why, and how it is handled.

What we collect

Account information. When you sign in, we receive your email address and name — either from Google (“Sign in with Google”) or from the email and password you enter to register. Used only to create and identify your LangUp account.
Words you save. When you save a word, we store the word, the sentence it appeared in, and the URL and title of the page you saved it from. This is your learning material.
Your chosen native language. Stored so we can translate saved words for you.
Login session. Authentication tokens are stored locally in your browser (chrome.storage.local) so you stay signed in. They are not shared with anyone.

We do not collect your browsing history. The extension only sends data when you explicitly save a word or sign in; it does not read or transmit pages you simply visit.

How we use it

To provide the core feature: saving words and building your vocabulary.
To translate saved words into your native language and generate practice exercises.
To keep you signed in across sessions.

Who we share it with

We do not sell your data and do not share it with advertisers or data brokers. Data is sent only to the LangUp backend at https://langup.piatek-magazyn.com, which stores your account and vocabulary. Google is used solely to verify your identity when you choose Google sign-in.

Data storage and retention

Your account and saved words are stored on the LangUp backend for as long as your account exists. Login tokens live only in your browser and are removed when you sign out.

Your choices

Sign out at any time from the extension popup to clear the local session.
Delete your data / account by contacting us at the address below.

Permissions

The extension requests only the permissions it needs (storage, identity for Google sign-in, context menu, and access to the LangUp API host). The content script runs on all sites so it can offer the “save word” button wherever you read, but it acts only on the text you select and only sends data when you click save.

Changes

We may update this policy; the “Last updated” date above will change accordingly.
