Frequently Asked Questions

Does CleanTools work offline?
Yes! File processing is 100% offline. For Personal subscribers, the extension performs a quick background license check every few days, but the file processing itself never touches the internet.
Why do you need internet if it's local?
Internet is ONLY used to verify your license key to prevent piracy and check for critical security updates. We never transmit, upload, or see your PDF files.
Is there a refund policy?
Yes, we offer a 14-day money-back guarantee, no questions asked. If you're not satisfied, just email us and we'll refund your subscription instantly.
What is the watermark?
The free version adds small text at the bottom of signed pages saying "Signed with CleanTools Free". Upgrade to the Personal plan to remove it completely.
