PictoClass privacy policy
PictoClass Chrome extension · updated 27 September 2026
In short
PictoClass does not collect personal data. There is no account, no analytics and no advertising. Everything you set up stays in your own browser.
What is stored in your browser
- The languages you choose and your settings.
- The words for the pictograms, the pronunciations found and recordings you make yourself with the microphone. Your own recordings are never sent anywhere.
This data is only kept in the extension's storage on your computer. You delete it by removing the extension.
What goes to other services
- Translation: the fixed words of the pictograms (for example "raise your hand") and the target language go to Google Translate (translate.googleapis.com), or if that fails to MyMemory (api.mymemory.translated.net). If you change the Dutch or English text of a pictogram yourself, that text is translated. If you type a sentence in the bubble, that sentence goes to the same services to be translated.
- Pronunciation: the word or typed sentence and the language go to Google Translate (translate.google.com) for a spoken version.
No data about you, your students or the pages you visit goes to these services. Their own processing is covered by the privacy rules of Google and MyMemory.
Extension permissions
PictoClass does not read web pages. The extension only places a layer with pictograms on the tab where you choose a pictogram. The bubble is shown on every website; Chrome asks for permission for this when you install it. PictoClass only uses it to show the bubble and does not read or store anything from those pages.
