Privacy, by design.
Every tool currently on SomethingTool runs in your browser. Files, filenames, image pixels, links, QR content, JSON, JWTs, regular expressions, and transformed text are never uploaded to our application servers.
What stays on your device
Tool inputs live in the memory of the page and its processing workers. Downloads are generated locally. Clearing a tool or leaving its page releases its working data. We do not put tool inputs in URLs, browser history, cookies, localStorage, or analytics.
Your preferences
We use localStorage for your theme, favorite tool slugs, and up to eight recently visited tool slugs. This contains tool names, never what you entered. You can clear it using your browser’s site-data controls. Tools work even when browser storage is unavailable. In that case, preference changes last only until this tab reloads.
We also store whether the browser bookmark reminder has been shown, so it does not keep appearing. This does not tell us whether you bookmarked the site.
Optional usage counters
If enabled by the site operator, the application sends only a tool slug, started/completed/failed counts, fixed format names, and broad size and duration buckets to a same-origin endpoint. These are aggregated by UTC date. There are no visitor IDs, session IDs, IP address columns, or event-level history in the application database. Do Not Track and Global Privacy Control disable these counters in the browser.
Website analytics and performance
We use Vercel Web Analytics to understand page visits and Vercel Speed Insights to measure loading speed and responsiveness. Vercel receives page and performance measurements, along with browser, device, and approximate location information. We remove query strings and URL fragments before reporting events, and Do Not Track and Global Privacy Control suppress these reports. We do not send tool inputs or attach custom tool-content events.
See Vercel Web Analytics privacy and Speed Insights privacy for details about their processing and retention.
Website delivery
Your browser still requests the website and its software from our hosting provider. The host necessarily receives connection information such as your IP address and may keep operational access logs. That is separate from tool processing: your inputs are not included in those requests. The Vercel measurement scripts are separate from tool processing. We load no advertising scripts.
Things to keep in mind
Your browser, operating system, extensions, and clipboard manager may have their own behavior. Copying a result puts it on your system clipboard; downloading creates a file on your device. Clearing a tool does not delete those copies.
