What it does, and what it does not

  • Processing happens locally in the browser; images, prompts, and conversation text are not uploaded. Review the privacy policy for the full disclosure.
  • It only cleans visible corner logos, stars, and marks on images you are authorized to use.
  • It does not remove or circumvent invisible provenance signals such as SynthID.
  • It does not process Gemini / Veo videos.
  • The current version targets visible corner marks. If Gemini changes its interface, we update the extension selectors. It does not promise every future layout will work immediately.
