Privacy Policy

Short version: every tool on this site runs in your browser. Anything you type, paste, drop, or upload stays on your device. The site collects only aggregate usage metrics that cannot identify you. No ads, no third-party tracking.

What the tools do with your input

Every tool — JSON formatters, PDF utilities, image converters, health calculators, all of them — runs entirely in your browser via client-side JavaScript. Your files, text, measurements, and any other input are processed locally and never transmitted to any server controlled by this site.

A few tools dynamically load third-party JavaScript libraries (for example pdf-lib, pdfjs-dist, or @zxing/browser) from the site's own bundle. These libraries run in your browser under the site's origin and do not send your data anywhere.

What the site collects

• Aggregate tool visits.When you open a tool, the site increments a per-tool counter in a Supabase database, keyed only by the tool's slug. No IP address, no user ID, no request details are stored alongside the count.
• Vercel Analytics. The site uses Vercel's privacy-friendly Web Analytics — no cookies, no cross-site fingerprinting. Aggregate page views and country-level location are recorded.
• Vercel Speed Insights.Collects anonymous Core Web Vitals (page load speed and similar real-user metrics) to help keep the site fast. Also cookie-less per Vercel's policy.
• Server logs. Vercel maintains short-retention HTTP request logs (standard for any hosting provider). These are not used for profiling.

Optional Google sign-in

The site includes an optional Google OAuth sign-in flow intended for future features that genuinely require user identity. If you choose to sign in, your email address and Google-provided profile basics are stored in Supabase. You can request deletion at any time via the contact channel below. If you never sign in, no account is created.

External services the site links to

The site links out to external services such as Ko-fi (donations) and third-party research / citation URLs. Those sites have their own privacy policies; the site owner has no control over what they do once you click through.

What the site does not do

• Sell, rent, or share your data with third parties.
• Display third-party advertising.
• Use tracking pixels, fingerprinting, or cross-site cookies.
• Store the files, text, or measurements you process in any tool.

Data retention

Aggregate visit counts are kept indefinitely. Any optional sign-in data is kept until the associated user requests deletion or the account is inactive for an extended period.

Children

The site is not directed at children under 13 and does not knowingly collect personal information from them.
