Osnovno jamstvo privatnosti: 100% obrada na strani klijenta

U Online Free Protractor (dostupan na onlinefreeprotractor.com), vaša privatnost naš je glavni prioritet. Cijela naša aplikacija radi lokalno unutar vašeg web-preglednika putem standardnih API-ja HTML5 Canvas, WebRTC i DeviceOrientation. Ne prenosimo, snimamo niti pohranjujemo vaše fotografije, nacrte, video streamove s kamere ili podatke žiroskopskih senzora na bilo kojem vanjskom poslužitelju.

1. Informacije koje ne prikupljamo

Učitane slike i nacrti: kada učitate fotografiju ili zalijepite snimku zaslona (Ctrl+V), datoteka se učitava izravno u lokalnu RAM memoriju vašeg preglednika. Nikakvi se slikovni podaci nikada ne prenose na poslužitelje u oblaku.
Feedovi s kamere uživo: AR značajka kamere aktivira videosenzor vašeg uređaja isključivo za prikaz pregleda uživo iza virtualnog kutomjera. Nikada ne snimamo, snimamo ili strujimo vaš video.
Podaci senzora kretanja i kompasa: Akcelerometar, žiroskop i telemetrija magnetometra (nagib, kotrljanje i azimut) obrađuju se u stvarnom vremenu isključivo za virtualno poravnanje igle i kutomjera.
Podaci koji mogu identificirati osobu (PII): Ne zahtijevamo registraciju računa, lozinke, imena, fizičke adrese ili telefonske brojeve za korištenje bilo kojeg alata.

2. Lokalna pohrana i postavke

Koristimo moderni preglednik localStorage isključivo kako bismo zapamtili željene postavke klijenta tijekom posjeta:

Postavke teme: Odabir teme tamnog ili svijetlog načina.
Device Preset: Vaš posljednji odabrani PPI profil zaslona za kalibraciju u omjeru 1:1.
Preference jedinice: Vaša odabrana jedinica linearnog mjerila (cm, mm, in, px).
