We build technology that you own. Not technology that owns you.
Every line of code runs on your device. Every file lives on your storage. Every decision is yours.
We don't collect data. We don't phone home. We don't sell your attention. We build tools and sell them once. That's it.
The mind is only as sharp as the will behind it. Logic Butter exists because we chose to build instead of complain. To find loopholes instead of excuses. To ship instead of pitch.
Built from a phone. Certified with 15,540 assertions. Shipped to the world.
Your data stays on your device. Period.
Zero cloud calls. Zero telemetry. Zero accounts.
Buy once, own forever. No subscriptions.
15,540 test assertions. Zero failures. Lambda Seal.
Print-on-demand. Zero inventory. Zero waste. Every piece made when you order it.

Logic Butter is what happens when you solve the problem instead of talking about it.
