You aren't actually 'uploading' anything. All the code that powers this PDF tool is downloaded to your browser the moment you visit the page. When you select a file, processing happens directly in your computer's memory. No data is transmitted over the internet.
Encrypted PDFs require decryption before assembly. If your PDF has an open password, unlock it before merging. Permissions-locked documents can be processed directly.
Tangent uses AES cryptography to lock your document entirely in your browser. Because it runs locally, your password and your confidential document are never uploaded to a server. If you use it on an existing PDF, the tool uses a secure "flattening" process that converts all pages to un-editable visual layers, completely destroying hidden metadata and preventing unauthorized text scraping.
All memory buffers allocated for your PDF are freed immediately by the browser's garbage collector. Zero files are retained on disk or cached on remote servers.
