Local data notice

• localStorage stores the interface language and theme preference.
• IndexedDB stores optional calculation cache, validation metadata, and recovery data.
• Cache Storage stores static application files for offline startup and efficient updates.

The current version sets no cross-site, advertising, or marketing cookies. Browser-local storage supports features you choose to use rather than tracking across websites.

Clear in the app removes the local calculation cache. To also remove language preference, offline files, and all IndexedDB data, use the browser's Clear site data function. FlopForge cannot remotely undo deletion.
