Lytho: Stone Management App

Lytho is the operational backbone for marble and stone yards. Run your yard from a phone: every block arriving, every slab cut, every hold for a regular customer, every sale, every truck dispatch — recorded and reconciled with full offline support. What Lytho does: • Inventory: tracks blocks and slabs with photos, defects, and dimensions (auto-converts between inches, cm, mm, and feet) • Hold → Sale → Dispatch: three distinct first-class events that match how Indian marble traders actually work • Production: log block-to-slab cutting across machines; mark dead stock; consolidate slab lots • Party ledger: every customer's outstanding balance, with sale and payment history • Truck logistics: receive trucks with two-step inventory confirmation; dispatch with multi-buyer support; full cascade-aware delete • Cash flow: clean inbound/outbound payment view (not a tax ledger — focused on real cash movement) What Lytho is NOT: • Not a billing or GST app — your accounting software remains the system of record for tax invoices, GST returns, and statutory books. Lytho records what actually happened in the yard; your billing software computes what's legally owed. Privacy: • Zero-knowledge encryption: keys never leave your device. Photos, party names, slab dimensions, ledger balances — all encrypted at rest. Even Lytho's servers can't read them. • Optional crash reporting (off by default) • Optional AI stone identification via Google Gemini (off by default, photos sent only when you ask) • Account export + delete tools available from Settings For: marble traders, stone-yard owners, factory managers, employees of stone businesses across India.
