Privacy Policy
Last updated: 8 November 2026
The short version
- Images you upload are deleted as soon as the check is finished. We never keep, share or look at them.
- We keep anonymous statistics about checks (like pixel size and result), but not your file name or anything that identifies you.
- Google Analytics cookies are only used if you click "Accept". You can change your mind any time.
- We show ads from Google AdSense. In the EU and UK, Google asks for your consent before using cookies for personalised ads.
- There are no accounts, and we don't sell data.
1. Who runs PrintCheck
PrintCheck (imageprintcheck.com) is run by Chris Bezuidenhout, who is responsible for your data under the EU General Data Protection Regulation (GDPR). For any privacy question or request, email imageprintcheck@gmail.com.
2. Images you upload
When you check an image, it is sent to our server so we can read its pixel dimensions and file format. Small files are handled in memory; larger files may be written to a temporary file for the second or so the check takes. Either way, the image is deleted as soon as the check is finished.
We never save your image to a database or cloud storage, never look at it, never share it, and never use it to train AI or for any other purpose. You keep all rights to your work.
3. Check statistics we keep
To understand how the tool is used and improve it, we record these details about each check:
- file type and file size (for example "JPEG, 2,400 KB")
- the image's pixel dimensions
- the print size and DPI you chose
- the result (pass, AI upscale candidate or fail) and the time of the check
We do not record your file name, your IP address or anything else that could identify you, so these statistics are anonymous.
4. Server logs
PrintCheck is hosted on Google Cloud (Google Cloud Run). Like almost every web host, it automatically records standard request logs: your IP address, browser type, the page requested and the time. We use these only to keep the site secure and fix problems, and they are deleted automatically after about 30 days. The legal basis is our legitimate interest in running a secure, working website (GDPR Art. 6(1)(f)).
5. Cookies and similar storage
| Name | Purpose | Type | Kept for |
|---|---|---|---|
| csrftoken | Protects the upload form against forged requests (security). | Strictly necessary | 1 year |
| printcheck_cookie_consent | Remembers whether you accepted or rejected analytics cookies (stored in your browser's local storage). | Strictly necessary | 12 months |
| _ga, _ga_* | Google Analytics: counts visits and shows which pages and features are used. | Analytics – only if you accept | Up to 2 years |
| __gads, __gpi, __eoi, IDE and similar | Google AdSense: shows ads, limits how often you see the same ad, measures ads and prevents ad fraud. See section 8. | Advertising – in the EU/UK only with your consent, given in Google's consent message | Up to 13 months |
You can change your analytics choice at any time with (also in the footer of every page). If you reject analytics cookies after accepting them, we delete them. Advertising choices are made in Google's own consent message, which you can reopen from the privacy link it shows on the page.
6. Google Analytics
If you accept analytics cookies, we use Google Analytics 4, provided by Google Ireland Limited, to see anonymous usage statistics such as how many people visit, which pages they use and roughly where they come from (country/city level). Google Analytics 4 does not log or store IP addresses. Google may process this data in the USA under the EU–US Data Privacy Framework. We keep Analytics data for no more than 14 months.
The legal basis is your consent (GDPR Art. 6(1)(a)). If you don't accept, Google Analytics is not loaded at all. More details: Google's Privacy Policy.
7. Fonts and icons
All fonts and icons are served from our own server, so loading PrintCheck does not send your IP address to font or icon providers such as Google Fonts.
8. Advertising
PrintCheck shows ads through Google AdSense, provided by Google Ireland Limited, to help cover the cost of running the site for free. Google's ad script loads on our pages. When it does, your browser connects to Google's servers, which receive your IP address, browser details and the page you are viewing. Google needs this to deliver ads and to detect fraud.
If you are in the European Economic Area, the UK or Switzerland, Google shows a consent message (a Google-certified consent tool) before using cookies or similar storage for personalised ads. If you don't consent, Google may show non-personalised or limited ads, which do not use your data to tailor ads to you. Google may process data in the USA under the EU–US Data Privacy Framework.
The legal basis for personalised advertising is your consent (GDPR Art. 6(1)(a)), which you can withdraw at any time. More details: how Google uses information from sites that use its services and Google's ad settings.
9. Affiliate links and Buy Me a Coffee
Some links (for example to print services or AI upscaling tools) are affiliate links: if you buy through them, we may earn a small commission at no extra cost to you. The "Buy me a coffee" links go to buymeacoffee.com. We don't share any of your data with these sites, but once you follow a link, that site's own privacy policy applies, and it may know that you arrived from PrintCheck.
10. Your rights
Under the GDPR you have the right to access, correct or delete personal data about you, to restrict or object to its use, to data portability, and to withdraw consent at any time. Because we don't keep accounts, file names or IP addresses with check statistics, we usually hold no personal data that can be linked to you. To make a request, email imageprintcheck@gmail.com.
You can also complain to a data protection authority, for example in the country where you live. In the Czech Republic this is the Office for Personal Data Protection (ÚOOÚ).
11. Changes to this policy
If we change how PrintCheck handles data, we'll update this page and the "Last updated" date above.
