Luminos
Privacy-first investment portfolio tracker designed for individual investors who refuse to compromise on security.
The challenge
Individual investors lacked a clean, secure, and privacy-focused way to track their diversified assets — stocks, crypto, real estate, fixed deposits — in a single dashboard without handing over bank credentials to third parties. Every existing option either required account linking or was cluttered with ads and upsells.
Our approach
We built a mobile-first application around manual and semi-automated entry with real-time market syncing. The architecture puts data privacy first: encrypted local storage, no third-party data brokers, and a backend designed so that even we can't read a user's portfolio. The UI is intentionally minimal — no noise, no dark patterns.
What we built
- Unified portfolio dashboard across all asset classes
- Asset allocation analytics with visual breakdowns
- Automated fixed deposit maturity calculations
- Real-time market price sync without account linking
- Encrypted local-first data architecture
Outcome
Launched on iOS and Android with strong early retention among privacy-conscious investors. Users consistently cite the absence of ads and the clean interface as the primary reasons they stayed — and referred others.
