Professional Capabilities
Engineered for Privacy, Speed & Precision
Everything you need to sign contracts, agreements, and tax forms without ever exposing your files to third-party cloud servers.
Ultra-Smooth Signature Studio
Draw natural vector signatures with variable stroke thickness (Fine, Medium, Bold) and rich document ink colors (Classic Black, Executive Blue, Review Red, Emerald). Or choose from 8 calligraphic script styles pre-populated with your name.
Magnetic Alignment Snapping
Position your signature, printed name, date, and checkboxes with pinpoint precision. Intelligent magnetic guide rails detect nearby fields and lock items into crisp horizontal and vertical alignment automatically.
Bank-Grade AES-256 Encryption
Lock your confidential business agreements, deeds, and tax forms with industry-standard 256-bit password encryption directly on-device. Restrict unauthorized opening, copying, or printing.
Biometric Vault Protection
Guard your entire document vault behind your fingerprint, face unlock, or device PIN. Features automatic re-lock protection when switching apps or locking your Android device screen.
Certified SHA-256 Audit Trail
Generate tamper-evident digital seals with unique SHA-256 cryptographic hashes. On-device audit logs record timestamps of document import, field preparation, and finalization to prove document integrity.
