Cookie Policy
Last updated: June 17, 2026
What This Site Uses
BallisticEngine uses essential browser storage only. We do not use advertising cookies, tracking pixels, or third-party analytics. Your browsing is not monitored or profiled.
Storage We Use
| Name | Type | Purpose | Duration |
|---|---|---|---|
theme | localStorage | Remembers your light/dark mode preference | Persistent |
tips | localStorage | Remembers if you disabled result tooltips | Persistent |
units | localStorage | Remembers Metric/Imperial preference | Persistent |
These are not cookies in the technical sense — they are localStorage entries that never leave your browser and are never sent to any server. They exist solely to remember your preferences between visits.
Third-Party Services
Supabase — Our ammunition and weapons database is hosted on Supabase (supabase.co). When the calculator loads, it fetches product data from their API. Supabase may set its own cookies for infrastructure purposes. See their privacy policy.
Google Fonts — We load typefaces (Rajdhani, Barlow, Material Symbols) from Google Fonts. Google may log font requests. See their privacy policy.
Cloudflare — This site is served via Cloudflare Pages. Cloudflare may set a __cf_bm cookie for bot protection. See their privacy policy.
What We Do Not Do
We do not run Google Analytics, Facebook Pixel, or any advertising network. We do not sell, share, or transmit your personal data. We do not fingerprint your browser. All calculations run entirely in your browser — no projectile or target data is sent to our servers.
Your Rights
Under GDPR (EU), CCPA (California), and similar regulations, you have the right to know what data is stored and to delete it. Since we only use localStorage, you can clear it anytime via your browser settings (Settings → Clear browsing data → Cookies and site data). This will reset your theme, tooltip, and unit preferences to defaults.
