PDF Redaction terms of service
These terms govern your use of PDF Redaction (the “app”), a macOS application published by WHITEFORGE TECHNOLOGIES LTD (“Whiteforge”, “we”), a company registered in England and Wales (company number 17224707). By installing or using the app, you agree to these terms.
How PDF Redaction handles your data is described separately in the PDF Redaction privacy policy.
1. Beta status
PDF Redaction is currently distributed as a pre-release (“beta”) version for evaluation and feedback. Beta versions may contain defects, may produce unexpected results, and may be changed or withdrawn at any time. Although every save is verified before completing (see section 5), you should keep a copy of any source document and review every redacted output before relying on it.
2. Licence
PDF Redaction is licensed to you, not sold. Subject to your compliance with these terms, Whiteforge grants you a personal, non-exclusive, non-transferable, revocable licence to install and use the app on Apple computers running macOS that you own or control.
3. Distribution
PDF Redaction is distributed directly by Whiteforge as a Developer ID signed and Apple-notarized disk image (.dmg), outside the Mac App Store. Apple’s notarization confirms only that the app has been scanned for known malicious components and is signed by an identified Apple developer; it is not an endorsement by Apple of the app’s functionality.
4. Acceptable use
You agree not to:
- use the app for any unlawful purpose;
- use the app to redact, alter, or destroy documents that you are legally required to preserve in their original form, or that you are not authorised to modify;
- reverse engineer, decompile, or disassemble the app except where applicable law expressly permits it;
- attempt to interfere with, circumvent, or disable any security feature of the app, including the per-save verification step.
5. Redaction is best-effort and must be checked
PDF Redaction is designed to remove text and image content from PDF files at the content-stream level, and to verify the result by re-opening the output and re-extracting text from the regions you redacted before letting the save complete. If verification fails, the save fails — PDF Redaction will not write a redacted file it cannot verify.
However, PDF formats are diverse and evolving, and Whiteforge cannot guarantee that every redaction will succeed against every document, font, encoding, image format, or producer in existence. You remain responsible for reviewing every redacted document before publishing or sharing it, including opening it in a different PDF viewer and attempting to select or extract text from the redacted regions.
6. No warranty
PDF Redaction is provided on an “as is” and “as available” basis. To the maximum extent permitted by law, Whiteforge disclaims all warranties, whether express or implied, including any warranty of merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that the app will be uninterrupted, error-free, or that it will redact every kind of content in every document.
You should not rely on PDF Redaction as the sole means of safeguarding sensitive information in documents you publish or share. Always review the redacted output in an independent viewer before distribution.
7. Limitation of liability
To the fullest extent permitted by law, Whiteforge will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, revenue, data, goodwill, or reputation, arising out of or in connection with your use of PDF Redaction — including any damages arising from a redacted document that nevertheless contains information you intended to remove.
Where liability cannot lawfully be excluded, Whiteforge’s total aggregate liability is limited to the greater of (a) the amount you paid for PDF Redaction in the twelve months preceding the event giving rise to the claim, or (b) ten pounds sterling (£10).
Nothing in these terms limits or excludes any liability that cannot lawfully be limited or excluded under the laws of England and Wales, including liability for death or personal injury caused by negligence, or for fraud or fraudulent misrepresentation.
8. Third-party components
PDF Redaction incorporates the following open-source components. Each is used under the terms of its respective licence, copies of which are included with the app:
- qpdf — Apache License 2.0. Used for PDF object-model manipulation.
- PDFium — BSD 3-Clause License. Used for page rendering.
- libjpeg-turbo — IJG / BSD-style licence. Used for JPEG decode and re-encode in partial-pixel image redaction.
- nlohmann/json — MIT License. Used for JSON parsing in the engine.
- Tauri — Apache License 2.0 / MIT License. Used as the application shell.
9. Third-party trademarks
“Apple”, “macOS”, “Mac”, and the Apple logo are trademarks of Apple Inc. “PDF” is a trademark of Adobe Inc. PDF Redaction is not affiliated with, endorsed by, or sponsored by Apple or Adobe. Their marks are used in PDF Redaction and on this website for descriptive purposes only.
10. Termination
You can stop using PDF Redaction at any time by moving the PDF Redaction.app bundle to the Trash. We may suspend or end your right to use PDF Redaction if you materially breach these terms. The disclaimers, liability limits, and governing-law sections survive termination.
11. Changes
We may update these terms from time to time. Updates will be reflected by the “Last updated” date at the top of this page. Material changes will be highlighted at the top for a reasonable period. Continued use after an update means you accept the revised terms.
12. Governing law
These terms are governed by the laws of England and Wales. Disputes are subject to the exclusive jurisdiction of the courts of England and Wales, except where mandatory consumer protection law in your country of residence grants you the right to bring proceedings in your local courts.
