Privacy Policy — SwiftKitHub
Last Updated: October 21, 2026. Complete transparency regarding cookies, analytics, and advertising compliance.
1. 100% In-Browser Local Execution Architecture
SwiftKitHub is engineered from the ground up as a stateless, client-side application. When you input product selling prices, manufacturing COGS, ad spend budgets, or upload document files (PDFs, images, CSV statements), that data remains strictly inside your device's web browser memory. Zero calculation parameters are transmitted across the internet to our servers or third-party APIs.
2. Zero Server-Side Logging & Zero Accounts
We do not operate user registration databases, login accounts, or remote data storage. We do not maintain server logs of your financial inputs, profit margins, conversion metrics, or confidential documents. Once you close your browser tab or clear your session, your inputs are completely cleared from volatile RAM.
3. Browser LocalStorage & Stateless URLs
To enable convenient quick-reloading of customized scenarios, our calculators support optional stateless URL permalinks. Input values are serialized directly into the URL fragment or query string. When you bookmark or share a link, the parameters travel in the link itself, never through a database. We also use standard browser LocalStorage solely to remember your pinned tool preferences and recent tool history on your device.
4. GDPR, CCPA, and Global Privacy Compliance
Because we do not collect, process, or sell personal identifiers or financial telemetry, SwiftKitHub conforms by architectural design to the European General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA). You maintain absolute ownership and control over your data at all times.
