The short version: we can't see your files.
Last updated: July 10, 2026
Your images
Every tool on this site runs entirely in your browser. When you drop an image into PrintSizer, it is opened, cropped, resized, and zipped by your own device. It is never uploaded, transmitted, or stored on our servers — there is no upload code in the site at all. You can verify this yourself: load the page, disconnect from the internet, and the tool keeps working.
Cookies
We set none. No cookie banner needed because there are no cookies — first-party, third-party, or otherwise.
localStorage
If you buy Pro, your license key and its verification status are stored in your browser's localStorage so you stay unlocked between visits. This data stays on your device; you can clear it any time via your browser settings. Nothing else is stored.
Analytics
We run minimal, first-party, anonymous analytics to understand which tools are useful: an event name (like "pageview" or "zip_download"), the page path, the referring site's hostname, and a timestamp. We do not store IP addresses, we do not fingerprint devices, we do not use any third-party analytics service, and none of it is tied to you as a person.
License verification
When you enter a Pro license key, it is checked against Gumroad (our payment provider) via our server. The only data involved is the key itself and the purchase email Gumroad returns, which is shown to you and stored only in your own browser. Gumroad's own privacy policy governs your purchase.
If you email us at hello@printsizer.com, we'll have your email address because you sent it to us. We use it to reply, and for nothing else.
Changes
If this policy changes, the date at the top changes with it. We won't quietly weaken it.
