Resecta

Resecta redacts PDFs entirely on your device — designed to remove the text in marked regions, not hide it. Run on-device detection or draw redaction regions by hand, review the proposed redactions, apply, then export. A verification pass checks the output before you share; verification is a check, not a substitute for your review. No accounts, no analytics, no data collection — the app makes no network requests of its own, and you can use it in airplane mode. Free and open source under Apache-2.0.
