Privacy Policy
Last updated: September 14, 2026 • Applies to all visitors of penggarisonline.com
1. Privacy Commitment & Client Architecture
Welcome to Penggaris Online HP CM (penggarisonline.com). We are deeply dedicated to protecting the privacy of every visitor. This digital ruler utility is built on a "Client-Side First" philosophy: all physical measurements, pixel scaling, ID-1 card calibrations, caliper readouts, and angle calculations run 100% locally in your web browser without transmitting screen visuals or hardware sensor data to our servers.
2. Data Stored Locally (Web Storage)
Our website does NOT require user registration, phone numbers, or credit card numbers. The only data stored consists of technical configuration settings retained inside your local browser memory (localStorage) for seamless continued use:
- Calibrated Screen Density (PPI): The calibrated pixels-per-inch ratio derived from your ID-1 card calibration for persistent 1:1 scale.
- Unit Preference: Your selected measurement unit (centimeters cm, millimeters mm, or inches in).
- Visual Theme Preference: Your preferred Dark Mode or Light Mode interface appearance.
- Sound Effects State: Toggle state for audio tick feedback and haptic vibration.
Note: This localStorage data resides entirely on your device and can be cleared at any time via your browser settings.
3. Hardware, Screen, and Camera Access
Core on-screen measurement functionality does not require access to your camera, microphone, contacts, or gallery files. Measurements are taken directly against your screen glass. Pointer and touch events are processed solely to slide the measurement pins (Pin A & Pin B).
4. Google AdSense & DoubleClick Cookie Policy
