Privacy & data handling

Your photos stay here.

Photos, dimensions and print calculations are processed in your browser.

Calculator inputs

Selected photos, image names, pixel dimensions, settings and calculation results are not sent to a PrintBatch application server. JPEG, PNG and WebP files are decoded locally, and scaled previews are held in browser memory. The calculator has no account system or database. It does not save your input in cookies or browser storage. Inputs and settings reset on reload. Normal back/forward navigation may restore the open page from browser memory. Clearing a batch removes its preview references; it does not delete files from your device.

Downloads

A CSV is generated in the browser and saved when you choose Save plan. That file contains your input names, dimensions and calculated results. Where it is saved, synced or shared afterward depends on your device and the software you use.

Website delivery

The public site is hosted on Cloudflare Pages. Visiting it makes ordinary requests for the page, scripts, images and fonts. The hosting provider receives network information, such as an IP address and request details, to deliver and protect the site. This is separate from the calculation inputs, which remain in the page.

Analytics, advertising and fonts

This version does not load advertising or analytics scripts and does not set application cookies. Fonts are served from the same site; the browser does not contact a font provider. There is no consent banner because optional tracking is not enabled.

External links

Links to calculation sources open independent websites with their own data practices. Your calculator inputs are not added to those links.
