1. Introduction

At Veewom Online Measurement Tools (located at https://veewom.com/ruler-online/), your privacy is one of our highest priorities. We are committed to transparency regarding any data processed when you visit our website.

2. Zero Measurement Tracking (Client-Side Privacy)

All calculations across our tools—including ruler calibrations, on-screen object measurements, protractor angles, screen pixel density computations, and unit conversions—execute 100% locally in your web browser using client-side JavaScript.

We do not record the length or dimensions of items you measure.
We do not track the angles you measure or the numbers you convert.
No measurement coordinates or inputs are transmitted to our servers or third parties.

3. Browser Local Storage (`localStorage`)

To enhance your experience, our online ruler utilizes standard HTML5 Web Storage (localStorage) to store your custom display calibration:

Key: veewom_ruler_ppi
Data Stored: A single decimal number representing your monitor's calibrated pixels per inch (e.g., 96.00).
Purpose: Allows the ruler to maintain your calibrated scale across browser sessions so you do not need to re-calibrate with a credit card on every visit.
Control: You can delete or reset this stored value at any time by clicking the "Reset PPI" button on the ruler or clearing your browser cache/cookies.

4. Web Server Logs

Like virtually all websites, our Apache web servers automatically record standard HTTP request logs when you access our pages. These logs may include:

Internet Protocol (IP) address.
Browser type and version (User Agent).
Date, time, and referring URL.
Requested files and HTTP response status codes.

These logs are used strictly for technical performance monitoring, DDoS mitigation, debugging broken links, and maintaining server security.

5. Contact Form Submissions

If you voluntarily contact us via our contact form, we collect your name, email address, and message content. This information is used exclusively to respond to your technical question or feedback and is never sold, leased, or added to marketing newsletters.
