Our Principles

What we stand for

Zero Data Collection

We never collect, store, or transmit your personal data. Everything stays on your device.

No Tracking

No analytics, no fingerprinting, no behavioral tracking. Your usage is your business.

No Accounts Required

Open any app and use it immediately. No signup walls, no email verification, no passwords.

Works Offline

Every app functions fully without internet. No servers, no cloud dependencies.

Zero Ads

No banner ads, no interstitials, no reward videos. Clean interfaces, always.

Free Forever

All apps are completely free. No in-app purchases, no premium tiers, no paywalls.

Why Kelthos

Apps built with purpose

We are not building another app factory. Each Kelthos app is designed to solve a specific problem perfectly, while respecting your privacy completely.

Privacy by Design

Privacy isn't an afterthought. Every app is architected from the ground up with zero data collection.

Instant & Lightweight

No loading screens, no splash pages. Open any app and it works in under a second.

Beautiful Design

Material Design 3 with dark mode. Every pixel crafted for a premium experience.

Built with Flutter

Native performance with Flutter. Smooth 60fps animations and responsive layouts.

Works Everywhere

No internet required. Use our apps anywhere in the world without connectivity.

70+ Purpose-Built Apps

Each app does one thing exceptionally well. No bloat, no feature creep.
