Privacy Policy & Data Governance

Last Updated: September 2, 2026

1. Zero-Upload Architecture

At NovaTools (toolboxs.tech), our fundamental technical premise is that we do not transmit, collect, process, or store your documents, photos, audio tracks, or videos on any remote servers.

All operations—including PDF merging, audio volume amplification, neural subtitle generation, image compression, video trimming, and EXIF scrubbing—execute 100% locally within your client browser sandbox using in-browser processing engines, WebCodecs, and Web Workers.

2. Zero Data Collection Spec

  • Zero collection or retention of document bytes, images, or audio buffers.
  • Zero logging of file names, metadata tags, passwords, or transcription text.
  • Zero requirement for user accounts, credentials, or tracking identifiers to use any tool.

3. Advertising & Functional Cookies

To maintain free, open-access infrastructure without paywalls, we may serve programmatic advertisements provided by third-party vendors, such as Google AdSense.

• Third-Party Vendors: Google uses cookies to serve ads based on prior user visits.

• Opting Out: Users may opt out of personalized advertising via Google Ads Settings or aboutads.info.
