When a document enters the browser interface, our compiled WebAssembly binary allocates an isolated virtual memory block. Standard PDF cryptographic dictionaries decode strictly within that sandbox without triggering network upload requests.

The moment you trigger download or terminate the browser tab, the operating system reclaims the volatile memory space. No temporary disk dumps exist, leaving zero forensic trace across public networks or hosted cloud buckets.

No remote persistence. Your confidential pages never touch external disks.

We engineered Lockstrip as an unhosted memory pipe rather than a file repository. Zero telemetry, zero disk writes, and zero retention.
