File Deletion & Security Policy

How NexKit Tools describes browser-local workflows and temporary backend processing.

1. File Lifecycle

  • Tools labeled Runs in your browser process selected files locally and do not upload those selected files to NexKit PDF Tools servers by that workflow.
  • Tools labeled Temporary server processing require a configured backend and may upload selected files only to complete the requested conversion, OCR, or processing task.
  • The current backend upload handlers write temporary files to a local uploads directory and attempt to remove them after processing or failure.
  • NexKit PDF Tools pages describe whether a workflow is browser-local, temporary server processing, or coming soon.
  • Some configured backend tools may send file content to an external service needed for the requested task, such as OCR or document conversion, when that backend is enabled.
  • Coming soon tools do not currently accept, upload, or process files.

2. Backend Upload Evidence

Source review found backend upload handlers for OCR and document conversion routes. Those handlers use local temporary upload storage and cleanup blocks that remove the uploaded file when the request finishes or fails. A fixed retention duration beyond that cleanup behavior was not verified.

Backend OCR or conversion routes can call configured external services when enabled. Browser-local tools do not use those upload routes for their file processing workflows.

3. File Privacy Principles

  • Browser-local workflows keep selected files on your device for that tool.
  • Uploaded file contents are not added to a public search index.
  • Tool pages describe whether a workflow is browser-local, temporary server processing, or coming soon.
