1. Local Processing Guarantee

All tool computations — including JSON formatting, token decoding, cryptographic hash calculation, password generation, and regex testing — run entirely on your client device using browser JavaScript and the Web Cryptography API.

Your tool inputs, tokens, secrets, outputs, and uploaded files are never sent to any server, database, or remote logging service. Nothing leaves your machine.

2. Telemetry & Analytics

On production deployments, ToolingO uses privacy-friendly Vercel Analytics and Speed Insights to measure basic page load performance and aggregate visitor counts.

Telemetry tracks only anonymous page URLs and Web Vitals metrics. Inputs, outputs, form contents, JWT payloads, secrets, passwords, and file data are strictly excluded from telemetry.

3. Local Storage

ToolingO saves your explicit theme choice (light or dark) and language preference in browser localStorage. No tracking cookies, session identifiers, or personal user profiles are created.
