There's actually a surprising amount of poll makers that are out there, so there's a lotta choice.

The following satisfy these requirements in no particular order:

• European (EU/EFTA, thus has to respect GDPR. National law, if prioritised above international, must not be more privacy-infringing.
• Open source.
• No tracking (or if there is tracking, it is fully anonymised).
• Lets you build forms and surveys.
• Must be platform-agnostic (allowing especially Linux) or be self-hostable.
• Not AI-powered.

I've left costs out of the equation, since if there's no tracking (and thus no ad revenue), a form must be financed in a different way, be it through a price, non-profit institutions, restrictions on forms such as how long it can stay up, amount of questions/forms, etc.

Furthermore, I'm only going to list max. 1 per country and not stuff from cooperations that already are popular for other reasons. This is because I don't want to foster vendor- or country-lock-in dependence. So no Nextcloud (even though it's pretty good).

LimeSurvey 🇩🇪 - what I've used. Pretty satisfied with it, has an intuitive form maker. It's pretty no-nonsense. Freemium, open-source. Can be self-hosted, on Linux.

CryptPad 🇫🇷 - also nice; can be self-hosted too. Freemium, open source (AGPL-3.0).

SurveyJS 🇪🇪 - lets you use JavaScript to build forms. Freemium and self-hostable, MIT open source.

Vue Flow Form 🇭🇷 - has a pretty modern design, can be integrated on websites or apps. Free and self-hostable, MIT open source.

Zeroform 🇦🇹 - static and dynamic, not much to say. Forms can be exported as CSV, textfile, and JSON. For Linux too, self-hostable, free and open-source (AGPL-3.0).

PHP FormBuilder 🇧🇬 - uses HTML. Free and open-source, self-hosted.

Hi, it think you could check out these alternatives:

• Cryptpad.fr (best alt., as far as I see it)
• tally.so
• bitpoll.de

Although I'm not sure about choice 2 or 3, choise 1 is best. You should check, if all functions you need are available.

So this is pretty good.

It's a list of things you need to do in order to make the use of Google forms gdpr compliant.

One thing they don't touch on is the use of personal accounts to collect data. People tend to use Google forms because it's easy to set up using their personal account, but that essentially removes any company oversight from the collection and data processing. This makes it much harder to satisfy the data controller requirements.

Of course if it's an external contractor gathering the data and processing it independently, your company is likely to dismiss all this as not their problem.

If it's real academic research it will have had to go through ethics approval, and this should include data handling, and gdpr compliance.
