Uninstalling the extension or clearing browser data can remove this local data. Internet access is used for: - Website PDF imports you request - Optional OCR language downloads - Purchases, licence activation and validation - Licence recovery and installation management English OCR is included. Additional supported language models are downloaded from jsDelivr when requested and cached locally. Your documents are not sent with these downloads. Optional website and local-file access are requested when you enable features that need them. There is no advertising or sale of user data. PRICING AND LICENSING alphaPDF Pro costs US$59 once, including applicable transaction taxes. There is no subscription or recurring charge. The final total is shown at checkout. A purchase supports up to three installations you control. Purchased Pro capabilities remain available while alphaPDF remains supported. Pro requires online activation and periodic licence validation. After successful validation, Pro can work offline for up to seven days before reconnecting. IMPORTANT CAPABILITY DETAILS Redaction rebuilds every page of the exported PDF as an image, removing the original searchable text, vector artwork, links and interactive forms. Review the exported result before sharing. Drawing a black annotation is not permanent redaction. Word conversion results vary by document. Comparison does not classify purely graphical changes without text. Visual signatures and detached seals are not Adobe-compatible certificate signatures or a managed electronic-signature service. alphaPDF does not edit arbitrary existing PDF text in place.
