If it’s personal, it’s private.
Your apps know you. We don’t.
Private apps without compromise, built with zero-knowledge encryption
Nyskra Sync
Your data syncs across people and devices, with zero-knowledge client-side end-to-end encryption. We cannot read it.
True Privacy
Only you, and the people you intentionally share with, can see what’s personal to you. Enforced by technology, not policy.
No-Compromise Apps
As personal apps became part of everyday life, you had to choose between privacy and convenience. With Nyskra, you no longer do.
Traditionally, syncing meant trusting a provider with your data. Nyskra Sync removes that requirement. Personal data is encrypted on your device. Only you hold the encryption keys.
No Readable Copy
There is no readable copy of your data on our servers. All app data is encrypted. Nyskra never holds the keys needed to decrypt your data.
Offline First
Nyskra apps function without a connection. Sync happens when possible, not as a requirement for use.
Zero-knowledge encryption
with sync & share.
Finally.
Share nothing. Or only with the people who matter.
You decide.
Back online?
Syncs instantly.
Only yours to see.
partner see shared data
Privacy used to be the compromise. Now it’s the upgrade.
Privacy, Lived.
Across Nyskra apps, personal things are private.
Peace of Mind
You don’t have to wonder how this might be used in the future.
Log Freely
No need to simplify, sanitize, or keep parts of your life out of the app.
Be Yourself
Even your personal app settings aren’t visible to us. They can’t be extracted for profiling or ads.
Better Over Time
Because logging is safe, you tend to log more consistently. Insights emerge naturally.
Calm & Finite
Made for moments, not endless scrolling. You open the app, do the thing, and leave.
Sharing, Naturally
Share personal things like you do in real life, without a company listening in.
Stays Set
Privacy lives in the system, not in settings or policies. It’s always there.
Privacy shouldn’t depend on policy.
There’s a difference between
“we won’t” and “we can’t.”
The usual promise
“We won’t read
your private data.”
Nyskra
“We can’t read
your private data.”
Nyskra builds personal apps and the zero-knowledge technology behind them, enabling the apps to work, sync, and share while keeping your personal data inaccessible to us.
Privacy, Native.
Across Nyskra apps, privacy is built into the technology itself.
End-to-end Encryption
Zero-Knowledge, client-side end-to-end encryption. Nyskra cannot access your encryption keys.
Zero-Knowledge Sync & Share
Syncing and sharing work inside zero-knowledge encryption, not as an exception to it.
Works Online and Offline
Offline-first across devices and people, with or without a connection. Sync happens when connection returns.
Non-Observable Personalization
App settings and preferences are encrypted and not readable by Nyskra.
Your Data, Always
Never locked in. Export to standard formats anytime.
No Ads
Third-party ads are not part of the product or the business model.
No Dark Patterns
Not built around clicks, engagement loops, or manipulation.
The App is the Product
User data created and shared across Nyskra apps is never readable by us.
All of
the features.
None of
the data access.
Nearly all personal apps force a choice: features or privacy. Because readable data on a server is treated as the default for personal apps.
Nyskra proves full-featured apps don’t require a company to read your personal data.
First in.
First to know.
If it’s personal, it’s private.
Your apps haven't caught up yet.
We're fixing that.
