Vittorio Poppe manages polyg and is the contact for questions about privacy and content. Contact: contact@polyg.eu.
Data on your device
Language choice, accessibility preferences, scores, records, streaks, mastery and scheduled reviews are stored only in your browser’s localStorage. polyg does not receive or synchronise this learning data. You can clear it in the game and remove all site data through your browser settings.
Cookies, accounts and advertising
polyg currently uses no account, advertising cookies, personalised advertising or visitor profiling. LocalStorage is used only to make the game and your local learning progress work.
Technical hosting logs
The production host to be confirmed before publication may process limited technical logs to deliver and secure the website, such as IP address, time, requested URL and browser information. polyg does not use this information for advertising or a learning profile. See the host’s privacy policy for details.
External sources
After an answer, polyg may show a direct link to an external dictionary. No learning results are sent with that link. The external website’s privacy policy applies once you open it.
Your rights
You can ask about processing, correction or deletion via contact@polyg.eu. Because learning progress stays on your device, only you can directly manage that browser data. You may also contact the Belgian Data Protection Authority via dataprotectionauthority.be.
