Browser-based calculations
The current calculators run in your browser without an account. We do not ask you to upload project photos or files.
Local storage
Saved inventory and project plans may use browser localStorage. That data remains in the browser unless you clear site data or a feature explicitly states otherwise.
Google AdSense and advertising
Leftover may use Google AdSense. Google and advertising partners may use cookies, web storage, device identifiers or similar technologies to deliver, limit, personalize and measure ads, detect fraud and report performance.
Consent and regional requirements
Where law requires consent before advertising or storage technologies are used, advertising should follow the consent choices available for that region. Some regions require a certified consent-management platform before personalized ads can be served.
QR leftover labels
If you create a QR leftover label, Leftover encodes the material type, quantity and dimensions in the URL fragment after the # symbol. That fragment is processed in your browser and is not included in the page request sent to the web server. Anyone who has the printed QR label can read the encoded material details, so treat labels as visible household/workshop information.
Technical information
Hosting, network and advertising requests can transmit IP address, browser and device information, referring page, requested URL and timestamps as needed to deliver and secure the service.
Your privacy choices
You can clear saved Leftover data with site controls or browser site-data controls, and manage cookies in your browser. Advertising choices may also be available through Google and other providers.
Children
Leftover is a general-audience DIY utility and is not directed to children under 13.
Third parties and changes
Third-party services operate under their own privacy practices. This policy may be updated as the site changes; the effective date above identifies the current version.
