The application

Your text never leaves your device. Swaperty performs keyboard-layout conversion 100% locally. The application has no account system, no telemetry, and makes no network requests except: (a) license activation/validation calls to Lemon Squeezy's licensing API (transmitting only your license key and an anonymous machine fingerprint — never your text), and (b) an optional update check (transmitting only the app version).

This website

We use self-hosted, cookie-free Umami analytics: aggregate, anonymous page statistics with no cross-site tracking and no personal data — which is why you don't see a cookie banner. Our web server keeps standard short-lived access logs (IP address, user agent) for security purposes, deleted automatically.

Purchases

Checkout is operated by Lemon Squeezy, LLC as merchant of record. Your payment details go to them, not to us; see the Lemon Squeezy privacy policy. We receive your email address and license information to provide support and license management, and use it for nothing else — no marketing lists without your explicit opt-in.

Your rights

Email contact@swaperty.app to access or delete the data we hold about you (typically: your purchase email and license records).
