Why Lethe Guard

Safe sharing

Export creates a new copy. Your original stays intact until you clear it.

Fast detection

Emails, tokens, names, and card-like patterns surface in seconds.

Review before export

Suggested, selected, applied—always visible. Nothing permanent until you confirm.

Scanned-file OCR

Screenshots and scanned PDFs: we read the pixels, you approve the boxes.

Questions

What is the difference between masking and redaction?
Redaction permanently removes or replaces content in the export—you cannot recover it. Masking obscures data while keeping structure, such as j***@domain.com.
Does Lethe Guard support screenshots and scanned PDFs?
Yes. Pro includes OCR. We detect text in images and scanned pages, show overlays for review, then export a safe copy.
Is the original file modified?
No. Lethe Guard works on a copy in your session. Export produces a new file; your upload remains unchanged until you delete it or it expires.
How long are files stored?
Uploads and findings typically expire within 24 hours. Exports use short-lived download links. See Privacy for exact periods.
Is this for technical users only?
No. Paste and review is enough for most people. Developers get JSON, logs, and token detection without extra setup.
