Saved codes

Questions

Short answers. Where the answer is 'no', it says no rather than 'not yet at this time'.

Accounts and storage

Do I need an account?
No. There is nothing to sign up to. Open a builder and start.
Where are my projects saved?
In this browser's IndexedDB storage. Not on a server, because there isn't one.
Do you upload my images?
No. Images are resized and re-encoded on your device using the browser's canvas, then stored locally.
What happens if I clear browser storage?
Your projects are deleted and we cannot recover them. Export a backup first. This is the cost of the local-first design, and it is a real one.
Why did my project disappear on iPhone?
Safari deletes storage for sites you haven't visited in about seven days. The workspace shows whether persistent storage was granted, but Safari usually only grants it for sites added to the home screen. Export backups if you use Safari.
Can I move a project to another computer?
Yes. Export the project or a full workspace backup, then restore it in the other browser. There is no sync.
Is my content stored on your servers?
No. The site is static files. Your project data never leaves the browser.

QR codes

Are QR codes permanent?
The pattern is. A QR code encodes your destination directly in the grid, so the image never expires or stops working.
Do QR codes expire?
The code does not. The destination can. If the domain lapses, the hosting ends, or the page is deleted, a perfectly good code leads nowhere.
Can I change a QR destination later?
Not for a code that already points at a final URL. That address is baked into the pattern. If the code points at a redirect page on a domain you control, you can replace that one file and every printed code follows.
Can I track QR scans?
No. Counting scans requires a server that logs each visit, and there isn't one. You can add UTM parameters so whatever analytics you already run on your own site attributes the traffic.
Why isn't analytics included?
It would need infrastructure that stays running, which would change what this product is. Faking it would be worse.
What is error correction?
Redundancy in the code. Levels L, M, Q and H recover roughly 7, 15, 25 and 30 per cent of the data if part is damaged or covered. Higher levels make a denser code, so use H when a logo sits in the middle and M otherwise.
Is my Wi-Fi password uploaded?
No. It stays in the page's memory, is encoded into the pattern on your device, and is not saved anywhere. Reloading the page clears it.
Why is there no WPA3 option?
No QR scanner reliably recognises a separate WPA3 token. The WPA setting is what WPA2 and WPA3 networks both expect, so offering WPA3 would produce codes that don't work.

Publishing

Can I use these codes commercially?
Yes. There is no licence on a QR code you generate. The pattern is determined by the content you encode, not by us.
Do you host my page?
No. We have no servers to host it on. You choose a host.
How do I publish it?
Export the ZIP, unzip it, upload the contents to a static host such as GitHub Pages, Cloudflare Pages, Netlify, or ordinary cPanel hosting. The publishing guide walks through it.
Can I use a custom domain?
Yes, through whichever host you pick. That part is between you and them.
Does the exported website depend on this app?
No, and that is the point. It is plain HTML, CSS and images with no framework and no calls back to us. Delete this site entirely and your page keeps working.
Can I export HTML?
Yes. Either a website ZIP with separate CSS and assets, or a single standalone HTML file for simple projects.

The product

Is QRPress free?
Yes. There is no checkout and no account. If anything is sold later it will be announced with terms attached, and nothing that works today would move behind a payment.
Are there API calls?
No. No QR API, no analytics, no maps lookup, no fonts loaded from a CDN. That is why there is no address autocomplete in the location generator.
Can I use the site offline?
Partly, once it has loaded. Offline support is not finished yet, and remote images or third-party embeds will not work regardless.
Can I put a logo in the middle?
Yes. Adding one raises error correction to H so the code survives the covered area, but always scan a printed copy before committing to a print run.
What is the difference between vCard and MeCard?
They hold the same contact details, but MeCard uses far fewer characters, so the printed code is less dense and scans better when small. vCard has the widest support; MeCard is best when the code must be tiny.
