This page explains how Paji Pocketbook handles data when you use its reference tools. Last reviewed: 2026-06-20.
Tool Inputs and Local Data
- Most lookup tables and converters run in your browser. Paji Pocketbook does not ask visitors to register an account.
- Some interactive checklists save progress in browser localStorage, such as travel packing lists. You can clear this through your browser's site data settings.
- Personal defaults you set (such as preferred size region and units) are kept only in browser localStorage — never uploaded, no sign-up required — and can be cleared anytime.
- The site uses first-party cookies for interface preferences, such as
DARK_MODE, and for the recent-used tools list, such as RECENT_USED_TOOLS.
Usage Signals
- When a public tool page is opened, the browser sends the tool key to
/api/tool-visit. The site uses this to maintain aggregate counters such as popular tools.
- The tool-visit endpoint receives ordinary HTTP request metadata. It uses the client IP address for short-term rate limiting, but the page-view counter request sent to the Paji backend contains only the site key and tool key.
- Public tools do not request precise browser geolocation.
Analytics, Ads, and Third Parties
- Google Analytics: Used for aggregate page-view and performance measurement. Known sensitive query parameters are stripped before page-view events are sent. Google explains that Analytics uses first-party cookies and may collect device/browser data, on-site activity, and IP address for service security and location estimation.
- Microsoft Clarity: Used for heatmaps and session replay on allowed production origins. Clarity is blocked when known sensitive query parameters are present. Microsoft explains that Clarity cookies use pseudonymous IDs to connect page views and generate aggregate analytics.
- Google AdSense / Google Ads: Used to display ads. Google and other vendors may use advertising cookies to serve ads based on visits to this site or other sites. You can manage personalized ads in Google ad settings.
- Browser requests to Google, Microsoft, or ad vendors may share ordinary request data such as URL, IP address, device/browser information, cookies, and referrer according to those providers' policies.
Your Choices
- Clear this site's cookies and localStorage in your browser to remove local preferences, checklist progress, and recent-tool history.
- Use browser cookie controls, private browsing modes, ad settings, or the Google Analytics opt-out browser add-on to limit third-party measurement.
- Avoid entering sensitive personal information into public reference tools unless a tool explicitly says it is designed for that data.
Updates
We update this page when the site's data behavior, analytics, advertising setup, or third-party documentation materially changes.
