Software designed for people who value privacy, security, and owning their own data. No ads. No tracking. No compromise.
Privacy-first tools built for real people with real needs.
The social web is broken. Reddit is a warzone. Facebook Groups are buried. Local news is scattered across a dozen apps you don't use anymore. Nooks fixes all of that. It's a community-driven platform built for organized knowledge sharing — not arguments, not ads, not algorithmic chaos. Topic-specific communities called Nooks each have their own live feed of posts (Crannies), RSS news sources, real-time NOAA weather alerts, and a clean interface that puts community content front and center.
Reddit communities are dominated by arguments, downvotes, and toxicity. Nooks is designed for organized knowledge sharing, not debate. People who just want useful information without the drama have nowhere good to go right now.
Facebook's algorithm buries group content. People joined groups years ago and stopped seeing posts from them. Nooks puts community content front and center with a clean, chronological feed.
Nooks pulls RSS feeds into topic-specific communities so people get news filtered through the lens of a topic they actually care about — space, weather, law, finance — rather than a firehose of everything.
Local Nooks (Shelbyville, Louisville, Lexington, etc.) give communities a single place to share local news, events, and alerts that Facebook and Nextdoor have made cluttered and ad-heavy.
LawTubers fill a real gap — people following legal cases and creators like LegalEagle have no dedicated community hub. Nooks builds one: organized, searchable, and noise-free.
A real-time NOAA weather banner gives people genuinely useful safety information baked directly into a platform they're already using — no separate app, no subscription required.
Secure Messaging Platform
Most messaging apps advertise encryption. XecureCom is built on it at every layer. A zero-knowledge architecture means the server functions as a blind relay — it stores only encrypted ciphertext and has no mechanism to read your messages, access your contacts, or reconstruct your keys. Privacy here is guaranteed by mathematics, not by policy.
Extended Triple Diffie-Hellman for session setup, then per-message key rotation via Double Ratchet. One compromised key reveals exactly one message — nothing before, nothing after.
Log in with biometrics or a hardware security key via WebAuthn passkeys. No passwords means no phishing, no credential stuffing, and no password reuse risk.
Send your GPS coordinates and battery level to trusted contacts with one tap. An unmutable alarm triggers on their device and persists until you confirm you're safe.
Contact lists are encrypted client-side and stored as opaque blobs. The server cannot read who you communicate with — not even your contact names are visible server-side.
Deleting your account destroys your encryption keys, making all historical messages permanently unrecoverable — even from backups. True deletion, not just hidden data.
Unlike Signal or WhatsApp, XecureCom doesn't tie your identity to a phone number — reducing the personal information exposed during registration.
| Feature | XecureCom | Signal | Telegram | |
|---|---|---|---|---|
| E2E Encryption (default) | ✓ | ✓ | ✓ | ✗ |
| Double Ratchet Protocol | ✓ | ✓ | ✓ | ✗ |
| No Phone Number Required | ✓ | ✗ | ✗ | ✗ |
| Passwordless Auth (Passkeys) | ✓ | ✗ | ✗ | ✗ |
| Encrypted Contact Storage | ✓ | ✗ | ✗ | ✗ |
| Emergency SOS with Location | ✓ | ✗ | ✗ | ✗ |
Community Safety App
Your neighborhood has eyes — GroundTruth gives them a voice. A real-time community safety platform that keeps residents informed about local incidents, hazards, and activity as it happens. No algorithm burying the posts that matter. No ads. No noise. Just your community, staying connected and aware.
Incidents and safety notices appear instantly for people in the affected area — no waiting for the evening news or refreshing a feed.
Alerts are filtered to what's actually near you. Know about what matters in your block, your neighborhood, your town — not the whole state.
Reports come from real residents, not scraped from wire services. The people in the community are the source — faster and more local than any news outlet.
Built on the same Greenlyz principles — no data harvesting, no surveillance architecture, no selling your location history to advertisers.
Private Cloud Storage & Collaboration
The cloud doesn't have to mean giving up control. OneStop is your own private infrastructure for files, documents, and team communication — self-hosted on hardware you own, with no third-party cloud provider ever touching your data. Your files, your server, your rules.
Deploy OneStop on your own hardware or private VPS. No Greenlyz server ever sees your files. No provider to breach, subpoena, or unexpectedly shut down.
Shared workspaces, document collaboration, and team communication tools — everything a team needs to work without relying on Google or Microsoft infrastructure.
Files are encrypted at rest and in transit. Even if someone gains physical access to your hardware, your data remains protected without the keys.
You decide the retention policy, the backup schedule, and when data gets deleted — permanently. No cloud provider deciding what happens to your files.
Support Ticket Management
Support tools shouldn't require a SaaS subscription that costs more than the problem it solves. Helpdesk is a clean, self-contained ticket management system built for teams that want efficient issue tracking without the bloat, the per-seat pricing, or the vendor lock-in.
Create, assign, prioritize, and resolve tickets in a focused interface designed for speed — not for enterprise upselling.
The right people get notified at the right time. Updates, escalations, and resolutions surface automatically without drowning your inbox.
Role-based access, team assignment, and priority tiers let managers and support staff work together without stepping on each other.
Deploy it yourself. Customer conversations, internal notes, and ticket history never leave your infrastructure.
Security is a core design decision across every Greenlyz product — from encryption architecture in XecureCom to platform hardening in Nooks.
Messages are encrypted on your device before they leave it. Only the intended recipient can decrypt them — not us, not your ISP, not anyone in between. Uses AES-256-GCM with X25519 key exchange.
Used in XecureCom. Every message uses a new key derived from the previous one. If an attacker somehow obtains a key, they can only decrypt that single message — not what came before or after.
Many Greenlyz apps connect directly between devices rather than routing through central servers. Messages aren't stored waiting to be hacked — they exist only on your device and the recipient's.
Apps like OneStop are designed to run on your own hardware. Your data never touches a third-party cloud unless you choose it. No provider to breach, subpoena, or shut down.
Actively researching CRYSTALS-Kyber lattice-based key encapsulation — NIST's post-quantum standard. A hybrid classical + post-quantum approach is already in testing for future releases.
We don't log who talks to whom, when, or how often. The less we know, the less can be subpoenaed or stolen. Sealed sender support in XecureCom further reduces server-side visibility.
Every layer of the Nooks platform is independently secured — from the login page to the payment flow.
Cost factor 12 with automatic salting. Even a full database dump can't reveal any password. Each crack attempt takes 200–400ms — computationally brutal at scale.
Login capped at 20 attempts per 15 minutes per IP. General requests at 300/15 min. Post creation at 10/min. Brute force is stopped before it gains traction.
A 32-byte cryptographic token embedded in every form, verified on every POST. Third-party sites cannot forge requests on a member's behalf.
Output encoding via EJS, server-side HTML stripping with a strict no-tags whitelist, Content Security Policy headers, and per-request nonces on inline scripts.
Every database query uses parameterized prepared statements. User input is never concatenated into SQL — malicious input is always treated as literal text data.
HttpOnly + Secure + SameSite=Lax cookies. Session data lives server-side in MariaDB, not in the cookie itself. JavaScript cannot access the session token.
No card data ever touches the Nooks server. Stripe-hosted PCI-compliant checkout with cryptographic webhook signature verification on every payment event.
Full TLS 1.2+ via Let's Encrypt. Helmet.js delivers HSTS, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy on every single response.
Unknown email addresses trigger a dummy bcrypt comparison so response time never reveals whether an account exists — preventing user enumeration attacks.
