Privacy
Here's a fun exercise: pick any app on your phone and count how many third-party SDKs it loads. Analytics, crash reporting, attribution, A/B testing, ad networks — the list goes on. Most apps phone home the moment you open them, and you'd never know it.
We decided early on that our apps would work differently. Every KK Studio app keeps your data on your device. Period.
None of our apps require you to create an account. There's no sign-up screen, no email collection, no "log in with Google." You download the app, open it, and start using it. That's it.
We also don't use any analytics or tracking tools. No Firebase, no Amplitude, no Mixpanel. We genuinely don't know how many times you open our apps or which features you use the most. And honestly? That's fine. We'd rather build something good and trust that people will tell us if something's broken.
Because we don't send data anywhere, our apps work completely offline. ID-Shield lets you watermark and redact identity documents without ever connecting to the internet. Your passport photos, ID scans, and driving license images never leave your device — they're processed right there on your phone.
Calmara, our relaxation and focus app, stores your journal entries, breathing session history, and mood logs locally using Apple's SwiftData. Your personal reflections stay personal. If you record custom ambient sounds, those stay on-device too.
Vaultly handles your finances — transactions, budgets, savings goals, and tax records — all stored locally with biometric protection. No cloud sync to a server we control. No data mining. Just your numbers, on your device, behind Face ID.
Privacy isn't just a feature checkbox for us. It's a design principle. When you're sharing sensitive documents with ID-Shield, writing in your journal with Calmara, or tracking your spending with Vaultly, you shouldn't have to wonder who else can see that data.
The answer with our apps is always the same: nobody but you.
We think more apps should work this way. And until they do, we'll keep building ours the way we believe they should be built.
