// 01 — no data collection

developertools.app does not collect, store, transmit, or share any data you enter into any tool on this site. All processing — Base64 encoding, JSON formatting, password generation, URL encoding, timestamp conversion, and HTML entity encoding — happens entirely in your browser using JavaScript. Your data never leaves your device.

// 02 — password generator security

// 04 — analytics

We may use privacy-respecting analytics that collect only anonymised, aggregated data (page view counts, referrer sources). No personally identifiable information is collected or stored.

// 05 — advertising

This site is ad-supported via Google AdSense. Google may use cookies and signals to serve contextually relevant ads. To opt out of personalised advertising visit Google Ads Settings.
