In short
- Your PDFs are processed entirely in your browser. They are never uploaded, stored or seen by anyone else.
- No accounts, no analytics, no advertising, no third-party trackers — and no cookies of our own.
- The only thing saved on your device is your language and theme — and only if you choose them yourself.
Your files
The PDFs you add are read and merged by code running inside your browser tab, using your own device's memory. Nothing is sent to a server, so there is nothing for us to store, inspect or lose. You can confirm this in your browser's network tab while you use the app.
Closing or reloading the tab discards your files. The merged PDF is created on your device and downloaded straight to it.
What is stored on your device
If — and only if — you pick a language or a colour theme, the app remembers it using your browser's local storage:
pj-locale: the language you chosepj-theme: light or dark
Cookies and preferences
We do not set any cookies ourselves. The two values above stay on your device, are never sent to us, and exist only so the app looks the way you asked next time. Until you choose, the app simply follows your browser's language and your system's theme without saving anything. You can remove the saved values at any time by clearing this site's data in your browser settings. The only cookie you may encounter is a strictly necessary security cookie from Cloudflare, described below.
Hosting and technical data
The site is delivered by Microsoft Azure Static Web Apps. As with any web host, Microsoft may process technical request data — such as your IP address, browser type, time and the page requested — to deliver the site, keep it secure and fix problems. We add no analytics or tracking of our own and do not use this data to identify you. Microsoft's own handling of data is described in the Microsoft privacy statement.
Domain and network (Cloudflare)
Our domain name is registered with Cloudflare, Inc., which acts as registrar. Traffic to this site is routed through Cloudflare's network (DNS and proxy), which sits between your browser and our host to speed up delivery and protect the site from attacks and abuse.
To do this, Cloudflare processes technical request data such as your IP address, browser type and the pages requested, and may set a strictly necessary security cookie (for example for bot protection). We do not use Cloudflare for analytics or advertising, and we cannot use this data to identify you. Cloudflare's handling of data is described in the Cloudflare privacy policy.
Third parties
Apart from the infrastructure providers described above, there are none. Fonts are bundled with the site rather than loaded from a font provider, and there are no advertisements, embedded widgets or social media buttons.
Your rights
Because the app does not collect personal data, there is normally nothing for us to access, correct or delete. If you are in the EU or EEA, you nevertheless have the rights granted by the GDPR: access, rectification, erasure, restriction, objection, and the right to complain to your data protection authority. Feel free to contact us with any question.
Changes to this policy
If we ever change how the app handles data — for example by adding a feature that needs a server — we will update this page before the change goes live and refresh the date at the top.
