13 of 15 tools never upload a byte

An invoice has your client's name and your bank details. A JSON payload has your production data. A QR code for a UPI payment has your VPA. None of that should travel to a stranger's server to be formatted. 13 of the 15 tools on tools.scult.in run entirely in your browser — the invoice generator (GST or VAT, eight currencies, print straight to PDF), the QR code generator (links, text, WiFi and UPI payments; PNG or SVG; no tracking redirect), the favicon generator (favicon.ico, PNGs and apple-touch-icon from an image, text or emoji), the JSON formatter (line-and-column errors), the word counter (Unicode-accurate, keyword density, platform limits), the UTM builder (your conventions saved locally). The two that aren't — the speed test and the AI visibility checker — say exactly what they send and where. Privacy as a feature, stated on every page. Try it free: https://tools.scult.in Built entirely solo and free for users, forever. If you're a company like Razorpay, Proton, Zoho that acquires or invests in tools like this, I'd genuinely love to talk — pranjulrathour41@gmail.com
