StyleSift is a local-first Chrome extension for extracting design tokens from the active page and saving private style guides.
Saved guides, extracted tokens, source titles and URLs, settings, and cached entitlement data stay in Chrome extension storage. StyleSift does not upload or sell this data.
StyleSift uses activeTab and a packaged script only after you explicitly request extraction. It inspects visual styles on that active page, does not run persistently across websites, and does not collect passwords, form data, cookies, or browsing history.
When you activate or re-check Lifetime, StyleSift sends the license key and fixed product ID to Gumroad’s HTTPS verification API. Gumroad handles checkout and payment details externally. Paid access may continue offline for up to 30 days after a successful verification.
StyleSift has no analytics, advertising, cloud account, remote scripts, CDN code, or embedded checkout. All executable code is packaged in the extension.
