⁉️ Frequently Asked Questions

Is Syntaxly.dev safe to use for sensitive data?

Absolutely. Syntaxly is built on a 'Zero-Persistence' architecture. All processing (like AES encryption or JWT decoding) happens locally in your browser. Your data is never sent to our servers.

Why is Syntaxly faster than other online tools?

We use SvelteKit and a minimalist approach to eliminate bloat. Our tools are designed for 'Swift' performance, providing instant results as you type without server round-trips.

Does Syntaxly store my JSON or API tokens?

No. We do not use databases for your input data. Once you close the tab or refresh the page, your data is completely wiped from your browser's memory.
