Privacy policy
Last updated October 2026. In short: the images and text you use in the tools stay on your device and are never sent to us or anyone else.
Your images and text
All tools work inside your browser. Photos, PDFs, signatures, documents and the text you type are processed on your device and are never uploaded to our servers or any other server. We cannot see them.
To survive a page reload, the Stacker keeps the images you add in your browser's own storage (IndexedDB) until you remove them. Some tools remember settings, such as your last preset, card text or watermark logo, in local storage. Passport photos, ID photos and signatures in Fit to size are kept only in memory and are gone when you close the page. You can clear all of this at any time by clearing this site's data in your browser.
Downloads of on-device engines
Some tools download an engine the first time you use them (for example the text reader or the background remover). These files come from this website and are stored by your browser so the tool works offline. Nothing about your images is sent when they download.
Hosting
The website is hosted on Vercel. Like any web host, it receives standard request information such as your IP address and browser type when pages and files are loaded, for security and to deliver the site. We do not use this to identify you.
Cookies
This site does not use advertising or tracking cookies.
Children
The site is a general-audience tool and is not directed at children under 13. It does not knowingly collect personal information from anyone.
Changes and contact
If this policy changes, the date at the top will change too.
Contact details will appear here soon.
