Privacy Policy

1. Photos & Artwork Stay on Your Device

All image tools on ltlprints.com—including the Print Size Calculator, Crop for Print tool, 4× Image Upscaler, 3D Canvas Preview, Wall Mockup, and Wall Decal Maker—process images locally inside your web browser using HTML5 Canvas and Web Workers. Your images are never uploaded to or stored on our servers.

2. Analytics (GA4: G-XY18423Z23)

We use Google Analytics 4 (G-XY18423Z23) to measure aggregate page views and anonymous tool interaction events (such as tool_used, export, upscale_complete, and affiliate_click). Image filenames and image contents are never sent to Google Analytics.

3. Email Cheat Sheet & Studio Pro Accounts

If you request the printable Print Size & DPI Cheat Sheet PDF via /api/subscribe, we store your email address to send the double opt-in confirmation and occasional new-tool announcements. You can unsubscribe in one click at any time.

If you purchase Studio Pro, payment processing is handled directly by Stripe Checkout and Stripe Customer Portal. We store only your email address, Stripe customer ID, and subscription status in Cloudflare D1 to verify magic-link sign-ins. We never see or store your credit card number.

4. Outbound Affiliate Redirects (/go/*)

When you click a printer button under /go/, you are redirected to the merchant's website along with non-personal context subids (such as the print size or tool name, e.g., 16x20_canvas). No personal data or uploaded photo is shared with affiliate partners.
