Security & Privacy
We treat uploaded files as sensitive data. When you use the PDF signing tool on PdfPeaks, files are transferred over encrypted HTTPS/TLS connections and processed on secure servers in isolated temporary storage. They are used only to perform the operation you requested. Uploaded files and outputs are not permanently stored, are not used to train machine-learning models, and are never sold or shared with third parties for marketing. Temporary files are automatically removed after processing. For full details, see our Privacy Policy and Terms of Service.
