Short version: Purify collects absolutely nothing. No files, no URLs, no analytics, no cookies, no personal data of any kind. Everything runs in your browser. We have no server-side component to send your data to.
Purify ("we", "us", "our") is a privacy tool operated by RuntimeZero, part of the Runtime Hub project. This Privacy Policy explains how we handle information when you use Purify at purify.runtime-hub.com.
We collect no personal data. The table below documents every category of data that could theoretically be collected and our position on each:
| Data type | Collected? | Notes |
|---|---|---|
| Images you process | NEVER | Processed entirely in browser canvas. Never transmitted. |
| URLs you clean | NEVER | Parsed client-side with the browser URL API. Never sent anywhere. |
| JSON payloads | NEVER | Processed in-memory via JSON.parse(). No server involved. |
| IP address | NOT LOGGED | Standard web hosting may log IPs for security; we do not retain or analyze them. |
| Cookies | NONE | We set zero cookies. None for tracking, none for preferences. |
| Analytics / telemetry | NONE | No Google Analytics, Hotjar, Plausible, or any third-party analytics script. |
| Account information | N/A | Purify has no accounts, no login, no registration of any kind. |
| Google Fonts | LOADED | Fonts are served by Google. Google may log your IP on font requests. See Google's privacy policy. Once loaded, the tool works offline. |
All data processing occurs inside your browser tab, using standard Web APIs:
Images are drawn onto an HTML5 Canvas element. The pixel data is read back and downloaded as a new file. The original file and its metadata are never read from disk beyond what the browser loads into memory for display, and nothing is transmitted over any network connection.
URLs and text are processed using JavaScript string operations and the browser's URL API, entirely in memory. The moment you close or refresh the tab, all data is gone.
JSON is parsed and walked using standard JavaScript. No data persists beyond your session.
The only third-party service Purify loads is Google Fonts (for typography). When your browser requests fonts, Google's servers receive your IP address as part of the standard HTTP request. We have no control over Google's data handling. You can review Google's Privacy Policy for details.
Once the page has loaded, Purify works completely offline. You can disable network access after the initial load if you prefer complete network isolation.
Purify sets no cookies and does not use localStorage, sessionStorage, or IndexedDB to persist any information. There is nothing to clear after using Purify.
Purify does not collect data from anyone, including children. The tool is suitable for use by anyone who understands its purpose.
If we ever add features that involve data collection (such as optional cloud storage), this policy will be updated with clear disclosure before any such change takes effect. The last-updated date at the top of this page will reflect any revisions.
