1. Cookies and similar storage
Cookies are small browser files. Similar technologies include localStorage and IndexedDB. They help a website remember a choice or keep a feature working.
2. Essential security storage
Cloudflare may use essential security cookies or comparable mechanisms to protect the site from abuse, fraud, and automated attacks. These are necessary for secure delivery.
3. Account session storage
When you sign in, essential authentication-session storage keeps your magic-link account signed in and protects account actions. It is not used to track you across unrelated sites.
4. App and preference storage
The calculator may use localStorage or IndexedDB for calculator and history data, preferences, queued sync work, cached rates, entitlement checks, and acknowledgement of this cookie notice.
5. No analytics or marketing cookies
We do not use analytics, advertising, retargeting, or marketing cookies. Analytics and marketing categories are unavailable because they are not used.
6. Your controls
Use Cookie preferences to review the essential-only approach. Essential storage cannot be switched off while using the site because it supports security and requested functions. You can also delete or block storage in browser settings; doing so may sign you out or prevent features from working.
7. Retention and contact
Cookie and session duration depends on their purpose; browser storage usually remains until you clear it, while account sessions expire or end when you sign out. Contact [SUPPORT_EMAIL] with questions.
