1. BROKER AUTHENTICATION & SECURITY PROTOCOLS
We use industry-standard security measures and OAuth 2.0 authentication protocols to interface with supported partner brokerages (such as Upstox and Zerodha Kite). Broker authentication occurs directly on the brokerage’s official portal. NULL Microsystems does not collect, read, or store your raw broker passwords, PINs, or secondary security credentials. We process strictly read-only session tokens necessary to render chart telemetry.
2. DATA WE COLLECT
To maintain terminal access and manage backend infrastructure, we collect minimal operational data:
- Identity & Account Data: Email addresses and encrypted account identifiers managed securely via Google Firebase Authentication.
- Billing Data: Subscription metadata and payment webhooks managed through secure payment gateways (Razorpay). Raw credit card or banking details are not stored on native servers.
- Session Metrics: Timestamps and audit counters required to enforce subscription parameters and fair-use compute allocations.
3. AGGREGATED MARKET TELEMETRY INDEXING
To monitor infrastructure health and analyze broad system load, CALIPER processes asset query logs (such as queried ticker symbols and derived statistical metrics). This data is stored in aggregated/anonymized form and separated from direct account identifiers, subject to our operational retention and security controls.
4. LOCAL APPLICATION STORAGE
CALIPER does not use invasive third-party tracking cookies. The application utilizes secure local machine storage within the software environment strictly to store your active Nexus Key (JWT) and session parameters. This ensures continuous application state preservation without requiring repeated daily authentications. Transmissions to cloud infrastructure are encrypted via HTTPS protocols.
