Data sovereignty

Your data stays
in your hands.

OS91 is the only mobile OS engineered, governed, and deployed entirely within India. From the moment a call is made to the moment data rests on disk — every byte stays under your control, within your jurisdiction, on infrastructure you own.

No foreign dependency
OS91 ships with zero Google Play Services, no Microsoft cloud hooks, no foreign analytics SDKs. Every network call is auditable. Any attempt to contact foreign endpoints is blocked at the kernel level by default.
Infrastructure you own
Deployed on your own on-premise hardware or your own private cloud tenancy. Elements91 has no access to your infrastructure. Your data, your servers, your jurisdiction.
Full audit rights for GOI
Government and defence customers receive full right to audit OS91 source code under mutual NDA. Independent security audits by empanelled agencies are actively supported. No black boxes, no exceptions.

Network architecture

A fully encrypted
security perimeter.

256-bit AES · Transport + payload layers

From device to data centre, every byte is encrypted, tunnelled through private channels, and inspected for anomalies. Suspicious transmissions are auto-quarantined. Backend infrastructure runs entirely on organization-owned servers within Indian jurisdiction.
