Cookies
SmartCalc does not use cookies of any kind — neither session cookies, persistent cookies, nor third-party cookies. No cookie consent banner is required because we set none.
localStorage (Browser Storage)
We use your browser's localStorage — a technology similar to cookies but with key differences — solely to improve your experience. Specifically, we store:
| Key | Purpose | Expiry |
|---|---|---|
| activeCalcId | Stores the identifier of the last calculator you used (e.g., "mortgage") so the app reopens to it on your next visit. | Persists until cleared; no automatic expiry. |
Unlike cookies, localStorage data is never sent to any server. It stays on your device.
How to Clear Your Data
You can remove all SmartCalc localStorage data at any time:
- Chrome/Edge: Settings → Privacy and Security → Site Settings → View permissions and data stored across sites → find this site → Delete
- Firefox: Settings → Privacy & Security → Cookies and Site Data → Manage Data → find this site → Remove Selected
- Safari: Preferences → Privacy → Manage Website Data → find this site → Remove
- Or use your browser's developer tools → Application → Local Storage → clear the entries for this site.
Third-Party Storage
We do not use any third-party cookies, pixels, or tracking scripts. The Currency Converter makes an outbound API call to fetch exchange rates, but this does not involve any cookies or storage on your device beyond what is described above.
Changes to This Policy
If we add any new forms of browser storage in the future, we will update this policy accordingly.
