A free QR photo app is fine for a friend's barbecue. For client work, it can quietly become a GDPR liability -- and the moment your name (or your client's) is on the event, that liability is yours. The problem is not that free tools are badly made; it is that consumer apps are not built to answer the questions professional and corporate work demands, and the gaps only surface when something goes wrong or a client's legal team asks. This is general guidance, not legal advice.
The specific risks are consistent. With a free consumer app you often cannot tell where guest data is hosted, whether it leaves the EU, or who can access it. There is usually no data processing agreement available -- so you cannot document the controller-processor relationship a corporate client requires. Some free tools monetise data or show ads, which raises further questions about how guests' photos and personal data are used. And retention and erasure are frequently opaque, making it hard to honour a deletion request or to say how long data is kept.
For a professional, none of that is acceptable once a real client is involved. You are expected to know where the data lives, to provide a DPA, and to handle consent and retention deliberately. A consumer app that cannot give you those answers turns a convenience into a risk you are carrying on the client's behalf -- often without realising it until a procurement form or an incident forces the question. We cover the duties in GDPR for event photographers.
The fix is to use a platform built for professional use: EU-hosted, with a DPA available, clear retention, and consent and erasure tools. Gathmo hosts guest media in the EU (Frankfurt), provides a GDPR Article 28 DPA on request, has no third-country transfer of guest data, and includes moderation and erasure tools -- so you can put your brand on guest media without inheriting a compliance gap.
