Your files are never uploaded
When you add a file, your browser reads it from your device and Kin-edit processes it inside the open tab. The website is a set of static files; there is no server or database that could receive, store or read a document. The page’s security policy also blocks it from sending data to any other server.
You can check this yourself
Select On-device only at the top of any page to see every network request the page has made. They are all the app’s own files. After your first visit you can also turn on airplane mode: every tool keeps working because nothing needs the internet.
Nothing is kept afterward
Files live only in the tab’s memory while you work. We don’t save them in browser storage, there are no accounts, and there is no document history. Closing the tab, or selecting Clear, releases them. Browsers free memory on their own schedule, so this is a strong practical guarantee rather than forensic erasure.
How redaction works
Pages with redaction boxes are rebuilt as images with the boxes burned in, so the text and images underneath are removed from the file rather than just covered. Before the download starts, Kin-edit re-opens the finished file and confirms that no text is left on those pages. If the check fails, nothing is downloaded.
Text recognition and signatures
Making a scan searchable and extracting transactions both run on your device. The recognition engine and its English language data are downloaded from this site the first time you use them; your page images are never sent anywhere. Signatures you draw or type are kept in the tab’s memory only and are gone when you close it.
Hidden data
Exported files have their author, title and editing-software details cleared. Photos are re-encoded, which removes camera details and GPS location. With “Remove hidden data” on, comments, links and form fields are removed from PDF pages too.
Sending contracts
Kin-edit never sends email. It prepares each file and message, and you send them from your own email account. Delivery and read receipts are handled by your email provider, not by us.
What we do collect
Our hosting provider keeps standard, anonymous traffic statistics such as page views. They never include document contents or file names. If that changes, this page will say so before it happens.
