Security & Data Privacy

To let you copy multiple times across your laptop and easily find clips later, the floating clipboard checks your system clipboard history.

100% Private & Local
Data stays stored entirely inside your laptop's secure sandbox. We do not use any servers.
No Background Battery Drain
Lightweight listening event that wakes only when you copy or focus the window.
Full Control
Data auto-deletes in 24 hours. Clear everything at any time in one step.

Local-First Architecture

Every calculator and converter on OneStepKit runs entirely inside your browser using JavaScript. When you enter a number, it is processed on your device, not uploaded to a server.

No Data Collection

We do not collect, store, or transmit any of the values you enter into our tools. There are no analytics scripts on tool pages, no form submissions, and no background network requests that carry your inputs.

Secure Connections

The entire site is served over HTTPS with TLS encryption. Your connection to onestepkit.com is always encrypted in transit.

Minimal Dependencies

We keep third-party dependencies to an absolute minimum. All core tool logic is hand-written. External libraries (e.g., PDF.js, pdf-lib) are loaded from trusted CDNs and used only when you interact with a specific tool.
