License verification: When you activate KitFlow Pro, we send your license key and a device fingerprint (CPU, screen resolution, language, timezone) to our server solely to verify your purchase and enforce the 3-device limit. This data is stored securely and never shared with third parties.
CDN services: This site loads fonts from Google Fonts and JavaScript libraries (JSZip, MozJPEG) from jsDelivr CDN. These providers may receive your IP address and user agent. See Google's Privacy Policy and jsDelivr's Privacy Policy.
Your images never leave your device. All compression happens locally in your browser using Canvas and WebAssembly. We have no access to your files, ever.
Payments are processed by Gumroad. We never see or store your credit card or PayPal details. See Gumroad's Privacy Policy.
We do not sell, rent, or share your personal information with advertisers or any third party. This tool has no ads, no trackers, and no analytics. Your data is never monetized.
We use localStorage to remember your license activation and language preference. No tracking cookies. No analytics.
You have the right to access, correct, or delete any personal data we hold about you. Since we store minimal data (license key + device fingerprint), most data can be cleared by removing this site's localStorage in your browser settings. For GDPR (EU) or CCPA (California) requests, email us.
