Cookie Policy
This Cookie Policy explains how VectorGraph uses cookies and similar technologies (like LocalStorage and IndexedDB) to recognize you when you visit our website.
1. What are cookies?
Cookies are small data files that are placed on your computer or mobile device when you visit a website. At VectorGraph, because we are an Offline-First Progressive Web App (PWA), we rely heavily on modern browser storage mechanisms (LocalStorage and IndexedDB) rather than traditional HTTP cookies.
2. How we use local storage
| Storage Type | Purpose | Lifespan |
|---|---|---|
| IndexedDB | Strictly Necessary. Stores your active project files, uploaded images, extracted coordinate datasets, and workspace folder structure so you don't lose work if you refresh the page. This data never leaves your browser. | Persistent (until manually cleared) |
| LocalStorage | Strictly Necessary. Saves your UI preferences, such as zoom levels, active tool mode (Scholar/Advanced), calibration axes, theme settings, and whether you have completed the onboarding tutorial. | Persistent |
| LocalStorage | Analytics Consent. Stores a flag (vg_cookie_consent) indicating whether you accepted or declined our analytics tracking. |
1 Year |
| HTTP Cookies | Performance & Analytics. Set by Vercel Analytics and Vercel Speed Insights to track anonymized page views and load performance metrics. Only set if you click 'Accept' on the cookie banner. | Session / 1 Year |
3. How can I control cookies?
You have the right to decide whether to accept or reject analytics cookies. You can exercise your cookie rights by setting your preferences in the Cookie Consent Banner when you first visit the site.
To clear all VectorGraph data (including your local projects), you can use your browser's Developer Tools (F12) > Application tab > Clear site data.
