100% Client-Side Privacy Guarantee
NEXUS AI processes all documents locally in your device memory. We do not upload, transmit, read, or store any of your confidential PDF files, signatures, or personal annotations on external cloud servers.
1. Local Processing Architecture & Data Retention
NEXUS AI Digital PDF Studio operates purely as a client-side web software application. When you load a PDF file, import a signature image, or draw an annotation:
All PDF rendering, canvas manipulation, and exporting happen inside your local web browser engine using HTML5 Canvas and WebAssembly.
Closing the browser tab or reloading the page permanently wipes all temporary session data and file buffers from your RAM.
2. Legal Status of Electronic Signatures
NEXUS AI provides visual electronic signature overlays (e-signatures) and custom text stamps. While electronic signatures are legally recognized under standard international regulatory frameworks:
- US ESIGN Act & UETA: Electronic visual signatures generated by NEXUS AI generally qualify as valid intent-based signatures for standard contracts, invoices, and general agreements.
- EU eIDAS Regulation: Signatures created via this tool represent "Basic Electronic Signatures" (SES). They do not qualify as "Qualified Electronic Signatures" (QES) which require cryptographic hardware tokens or identity verification.
- User Discretion: You are solely responsible for ensuring that visual digital signatures comply with your specific legal jurisdiction, legal proceedings, financial contracts, or government filings.
3. Limitation of Liability & No Warranties
The NEXUS AI software, tools, scripts, and documentation are provided strictly on an "AS IS" AND "AS AVAILABLE" BASIS without warranties or conditions of any kind, either express or implied, including but not limited to merchantability or fitness for a particular purpose.
Disclaimer of Consequential Damages:
In no event shall NEXUS AI, its developer, or associated maintainers be held liable for any claim, damages, legal disputes, loss of data, corrupted documents, browser crashes, loss of profits, or operational disruptions arising out of or in connection with the use or inability to use this platform.
4. User Responsibilities & Document Accuracy
