Privacy Policy
Calc Drawer does not send your inputs to a server. Every calculation runs only inside your browser.
1. Information collected
Calc Drawer does not offer signup or login, and it does not collect personally identifiable information. Values entered into the tools are used only inside the browser and are not transmitted or stored externally.
2. Cookies and local storage
Calc Drawer currently does not use first-party cookies or store input values in browser local storage. Some tools may later use local storage to restore recent inputs on a future visit, but that data would remain only on the user's device.
3. External resources
The site loads the Pretendard Variable font from the external CDN cdn.jsdelivr.net. During that request, the user's IP address may appear in CDN logs.
4. Analytics and advertising
Calc Drawer uses Cloudflare Web Analytics to understand site usage and improve performance.
Calc Drawer may also use Google AdSense to help cover operating costs.
For more on Google's advertising cookies and data handling, see the Google Privacy Policy →. Users can disable personalized ads in Google Ad Settings →.
5. Third-party sharing
Calc Drawer does not sell or provide user information to third parties.
6. User rights
Data stored inside the browser can be removed at any time using the browser's site data controls.
7. Policy changes
This policy may be updated as the service changes. Material updates will be announced on the site, and the latest version remains available on this page.
