Building secure, privacy-respecting infrastructure for real-world digital systems.
StealthLynk is a technology company focused on designing and engineering secure software solutions for practical, real-world use. Our work bridges modern cryptographic systems, decentralized technologies, and conventional infrastructure, with an emphasis on reliability, transparency, and regulatory awareness.
What We Build
Secure Client & Network Software
StealthLynk develops cross-platform applications and backend systems designed to operate across desktop, mobile, and server environments. Our solutions focus on explicit security boundaries, client-side processing and encryption models, interoperability with existing infrastructure, and practical deployment without unnecessary abstraction.
Released
PhotoLynk
Backup Your Photos & Videos Securely. Preserve full-resolution media with no compression, keep every EXIF field intact, ingest RAW and pro formats, and run byte-level integrity checks before anything leaves the device. Encryption is end-to-end, so only you ever see the data.
Sync & Restore Across Devices. Pair phones, tablets, and desktops by QR code, mirror entire libraries on demand, and choose between self-hosted servers (free on GitHub) or StealthCloud’s managed infrastructure.
Ultimate Privacy & Ownership Protection. Zero-knowledge StealthCloud storage, cryptographic hashes, authenticity certificates, duplicate cleanup, and a strict promise of no ads, tracking, or data resale.
Certified Photos Album. Issue tamper-evident certificates that lock in the file bytes, EXIF metadata, capture context, and ownership history. Transfer certificates via blockchain links, keep them accessible forever, and use them as proof for licensing, archives, or IP defense.
StealthCloud Plans. Subscriptions at 100 GB / 200 GB / 400 GB / 1 TB with a 7-day free trial, or a one-time $50 lifetime plan (20 GB, 25 included verifications, 250 bonus verifications with zero PhotoLynk fees, plus unlimited top-ups). All formats—JPG, HEIC, PNG, RAW, CR2, NEF, DNG, more—are stored byte-for-byte.
Grace Period After Expiration. Lapsed subscriptions get a 3-day read-only window to download everything. No uploads or edits, no auto-deletions, and certificates remain user-owned via on-device keys.
Desktop
SHA-256 Integrity Verification
After downloading, verify file integrity by comparing the checksum.
In Development
A cross-platform SDK for secure identity verification and authentication. Infrastructure components intended for integration into third-party applications.
These efforts focus on enabling secure registrations, logins, and verifications without exposing unnecessary user data.
Engineering Principles
Open Development
Portions of our work are developed openly. We believe transparent engineering improves security, auditability, and trust.
