Privacy and local storage
The calculator works in your browser. This version has no user accounts, advertising scripts or analytics integrations.
Calculator inputs
Your mold dimensions, quantities, ratio settings and prices are processed on your device. The calculator does not transmit them to an application server.
Saved projects
When you choose “Save on this device,” ResinBatch stores project settings in your browser’s local storage. The unit preference is also kept locally. This data is not synced between browsers or devices. Browser privacy settings or clearing site data can remove saved projects.
You can print or download a batch sheet as a separate copy. The project manager also lets you delete a saved project. You can undo the most recent deletion while the page stays open. Closing or reloading the page ends that undo option.
“Start from blank” keeps a temporary copy of the previous working batch so you can restore it while the page is open. This temporary copy is kept in memory, not saved to browser storage; reloading or closing the page removes it. Starting another blank batch after making changes replaces that temporary copy.
Hosting and external links
The public site uses Google Firebase Hosting. When you visit the hosted site, Firebase receives your IP address as part of serving its pages. Firebase states that Hosting uses IP addresses for abuse detection and usage analysis and retains that IP data for a few months. See Firebase’s privacy and security documentation for its current practices.
Hosting a page does not send your calculator inputs or locally saved projects to Firebase. This version has no Firebase Analytics, database, authentication or other Firebase SDK integration. Manufacturer links open third-party websites with their own policies.
