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. Google banner advertising
Eligible Free web-app pages may load Google AdSense. Google and its advertising partners may use cookies or similar technologies to deliver, limit, secure, and measure ads. Verified Pro users do not receive web-app ad requests. Marketing pages, account pages, authentication callbacks, and subscription-management screens do not contain AskSum ad slots.
6. Your controls
Essential storage cannot be switched off while using features that depend on it. Google Privacy & Messaging provides consent, rejection, management, and revocation controls where required, including choices for personalized, non-personalized, or limited advertising. You can also block or delete browser storage, although 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.
