Cookie & Local Storage Policy

Last Updated: September 28, 2026

1. What Are Cookies and Local Storage?

Cookies and local storage are small data files stored directly on your computer or mobile device by your web browser when you visit a website.

2. How We Use Browser Storage

• Strictly Functional Local Storage: TileFlow Pro uses your browser's localStorage solely to remember your active room dimensions, tile layout configurations, and color theme preferences so your work is not lost when you refresh the page. This data never leaves your device during free calculator use.
• Performance & Web Analytics: We use Vercel Web Analytics to measure site uptime, server response times, and page traffic trends without tracking individual users or using invasive third-party cross-site advertising cookies.
• Payment Processor Cookies: When accessing the checkout modal or hosted LemonSqueezy payment pages, LemonSqueezy and its payment partner (Stripe) may use essential cookies strictly necessary for fraud prevention, session security, and payment processing.

3. Managing Your Preferences

You can clear your stored layout data at any time by clearing your browser's cache/local storage or clicking the "Reset" button within the calculator sidebar.
