JIN

Jin is a civil site management platform built for construction sites, supervisors, and frontline workers. Designed for real-world site conditions — low connectivity, multilingual teams, and demanding environments — Saath brings accountability, transparency, and digital traceability to your on-site operations. ━━━ For Supervisors & Engineers ━━━ Raise and Manage Work Tickets Create structured work tickets from your phone — attach photos, assign categories, and set priority levels. Track the full lifecycle of every issue from open to closed, with timestamped audit trails. SLA-Aware Issue Tracking Each ticket is color-coded by urgency and category type. SLA timers ensure critical issues never go unnoticed. The intuitive inbox surfaces what needs your attention, right now. Digital Evidence & Sign-Off Capture on-site photo evidence and collect digital signatures directly within a ticket. No paper. No lost records. ━━━ For Workers ━━━ Biometric Identity, Zero Login Workers never manage usernames or passwords. A quick fingerprint scan identifies the worker at the moment of each action — raising a ticket, signing a closure, or recording attendance. Site-Bound Kiosk Mode Shared site devices operate in a session-less kiosk mode, permanently bound to a site. Workers interact, sign, and submit — the device never holds personal data between sessions. Multilingual Support The interface supports Marathi, Hindi, and English, with audio narration guiding workers through key flows — designed for teams with low digital literacy. ━━━ Privacy & Compliance ━━━ Jin is built with DPDP (Digital Personal Data Protection) Act, 2023 compliance at its core. Biometric data is validated on-device only — no raw fingerprint templates or face embeddings are ever transmitted to or stored on servers. Consent records are maintained with timestamps and are fully auditable. ━━━ Built for the Field ━━━ • Offline-first: Tickets queue locally and sync when connectivity is restored • High-contrast UI designed for bright sunlight and gloved operation • Large touch targets meeting accessibility-grade sizing • Low-bandwidth ready — minimal data footprint for 2G/3G site networks ━━━ Technical Highlights ━━━ • React Native New Architecture (Hermes engine) for fast, reliable performance • On-device ML inference (TensorFlow Lite) for biometric face embedding • Firebase push notifications for real-time ticket updates • R8 code optimisation for minimal app size Jin is a Delpat product — built for the people who build India.
