Dutch Subtitle Translator (browser extension) — last updated 2026-07-22

What this extension does

This extension reads the Dutch subtitle text a supported video player (Videoland, KIJK, or NPO) is already displaying, sends that text to a translation service, and shows the translated result as an overlay on top of the video. It does not access, collect, or transmit anything else from the pages it runs on.

What data is sent, and to whom

Only the subtitle line currently on screen is sent, to whichever translation provider is selected in the extension's settings:

Default ("Free") provider: subtitle text is sent to Google's public translation endpoint (translate.googleapis.com). This is the same endpoint used by the Google Translate website; no account or personal identifier is attached to these requests by the extension.

Optional DeepL provider: if you choose to enter your own DeepL API key, subtitle text is instead sent to DeepL's API (api-free.deepl.com or api.deepl.com) along with that key, so translation usage is billed/tracked against your own DeepL account. Your key is stored only in your browser and is never sent anywhere except directly to DeepL.

No other page content, browsing history, personal information, or identifiers are ever read or transmitted by this extension.

What data is stored, and where

All settings — enabled/disabled state per site, target language, appearance (size/color/font/position), and your DeepL API key if you provide one — are stored locally in your own browser using the standard chrome.storage.local extension API. This data stays on your device. The developer of this extension does not operate a server, and does not receive, see, log, or store any of it.

Analytics and tracking

This extension contains no analytics, telemetry, advertising, or tracking of any kind. It does not use cookies.

Third-party services

Translation requests are subject to the respective privacy policies of the service you've selected: Google Translate, or DeepL if you've configured your own API key. This extension has no control over, and takes no responsibility for, how those services handle the text sent to them.

Changes to this policy

If this extension's data handling ever changes, this page will be updated accordingly, along with the "last updated" date above.
