Pangunahing Garantiya sa Privacy: 100% Pagproseso sa Gilid ng Kliyente

Sa Online Free Protractor (maa-access sa onlinefreeprotractor.com), ang iyong privacy ang aming pangunahing priyoridad. Ang aming buong application ay lokal na tumatakbo sa loob ng iyong web browser sa pamamagitan ng karaniwang HTML5 Canvas, WebRTC, at DeviceOrientation API. Hindi kami nagpapadala, nagre-record, o nag-iimbak ng iyong mga larawan, blueprint, camera video stream, o data ng gyro sensor sa anumang external na server.

1. Impormasyong Hindi Namin Kinokolekta

Mga Na-upload na Larawan at Mga Blueprint: Kapag nag-upload ka ng larawan o nag-paste ng screenshot (Ctrl+V), direktang nilo-load ang file sa lokal na memorya ng RAM ng iyong browser. Walang data ng imahe ang naililipat sa mga cloud server.
Mga Live na Feed ng Camera: Ina-activate ng feature na AR ng camera ang iyong video sensor ng device para lang magpakita ng live na preview sa likod ng virtual na protractor. Hindi namin kailanman nire-record, nag-snapshot, o nag-stream ng iyong video.
Data ng Motion & Compass Sensor: Accelerometer, gyroscope, at magnetometer telemetry (pitch, roll, at azimuth bearing) ay pinoproseso sa real time para lang sa virtual na karayom at protractor alignment.
Personal Identifiable Information (PII): Hindi namin hinihiling ang pagpaparehistro ng account, mga password, pangalan, pisikal na address, o numero ng telepono upang gumamit ng anumang tool.

2. Lokal na Imbakan at Mga Kagustuhan

Gumagamit kami ng modernong browser localStorage para lamang matandaan ang iyong ginustong mga setting ng kliyente sa mga pagbisita:

Kagustuhan sa Tema: Madilim na Mode o Light Mode na pagpili ng tema.
Preset ng Device: Ang iyong huling napiling screen PPI profile para sa 1:1 scale calibration.
Yunit Preference: Ang iyong napiling linear scale unit (cm, mm, in, px).
