Frequently asked questions
Are images or search terms sent to an external server?
No. OCR runs inside the extension. Image content, search terms, OCR results, and copied text are not sent to an external OCR, AI, analytics, advertising, or developer server.
Which languages can it recognize?
Choose from 11 packaged recognition groups covering 106 printed languages. English and Korean are enabled by default. OCR recognizes text; it does not translate it.
Can I search before OCR finishes?
Yes. HTML matches and completed image matches remain usable while later images continue processing.
Can I delete the local OCR cache?
Yes. Extension Settings can clear only OCR records or delete all extension-owned local data. Site permissions must be revoked separately.
Does it contain ads or analytics?
No. Version 1 contains no ad SDK, ad UI, ad-network request, user analytics, or remote configuration.
