Wordo is a small service. It stores what it needs to look up your words and to remind you of them, and nothing else.
Everything runs on Amazon Web Services in Paris (eu-west-3). Emails are sent through Amazon SES and notifications through Google’s Firebase Cloud Messaging: they handle your email address or your device token, and the content of what is sent. Definitions come from Wiktionary and are stored on Wordo’s own servers, so no lookup is sent to anyone else. Pronunciation recordings are not copied: when you play one, your browser fetches it from Wikimedia Commons, which then sees your IP address, as any website you visit does. There are no advertising or analytics trackers in the web app, the Android app or the Chrome extension.
The extension reads nothing from the pages you visit. The only thing it sends is the text you selected, in the address of the Wordo page it opens. The Android app keeps a copy of your words on your phone so that they are there offline; its text-selection action only receives the text you selected.
Everything is kept while your account exists. Settings → Delete your account removes your account, words, digests and device tokens immediately (how to delete your account, also without signing in). The running totals on the home page (words looked up, reminders sent) are plain counts, not tied to anyone.
You can stop email digests at any time with the link at the bottom of each one, or in Settings.
