BoldWords does not require an account. Saved words are stored in local storage on your current device and are not synced to a BoldWords server.
When you search, the word you enter is sent to Dictionary API (dictionaryapi.dev) for definitions and Datamuse (api.datamuse.com) for related words. These services may receive standard request metadata such as your IP address. Their own privacy terms apply.
If AI tutoring is enabled, your chat messages are sent to the BoldWords server and then to the AI provider configured for the server to generate a reply. The server request is configured not to store the model response. Hosting logs and provider terms may apply; do not share sensitive information in tutor messages.
BoldWords loads typefaces from Google Fonts. Your browser may contact Google Fonts to retrieve those files.
Pronunciation playback uses audio recordings where available or the speech voices installed on your device. Speech playback is handled by your device's browser or operating system.
BoldWords currently has no payment or account system. This page describes the current app version and should be reviewed if those features are added later.
