Cookie Policy

Working draft — pending human review. This policy describes cookies and similar storage used by the current free early-access version of FormulaClear.

What this site stores in your browser

Preferences. The site stores your theme choice (light or dark mode) in local storage so the page looks the way you left it. No personal data is included.

Session storage. If you use account features that are enabled, the site sets a session cookie so you stay signed in. The free check-up requires no account and sets no cookie.

Language. Older versions of this site offered a /zh path; the language switcher has been removed and no language cookie is set on this site.

What we don't use

• No advertising cookies and no cross-site trackers.
• No analytics that build individual profiles.
• Formula sheets are parsed in your browser and are never written to any storage outside your device.

Third parties

Our hosting runs on Cloudflare Workers infrastructure, whose standard request logging operates under Cloudflare's terms. If email or payment providers are connected in later phases, this section will be updated before those features go live.

Changes to this policy

This is a working draft. Changes will be noted on this page with a new revision date.
