GDPR Compliance Check
For those who haven't heard of it before, Gumb is
A platform for managing meetings, gatherings, and events for communities of any size. - gump.app/en
I have investigated this app because it is used by a club where I am occasionally active.
Landing Page / Homepage
Fonts: The landing page is using google fonts, so those fonts are loaded (8 requests) from fonts.gstatic.com when opening the website.
The first issue here is that google fonts are not listed in the privacy policy at all.
Second, by a German court ruling google fonts are not compliant with the GDPR:
The use of external font services cannot be based on Art. 6 § 1 p.1 f GDPR, as the use of the fonts is also possible without having to establish a connection from visitors to external servers. - LG München Az. 3 O 17493/20
Images: Furthermore the website is loading images from firebasestorage.googleapis.com (105 requests). Following the argumentation of the previously mentioned court ruling, using firebase for images could also be considered non-compliant because images could easily be served without having to establish a connection from visitors to external servers.
Youtube Embed: The website includes a youtube iframe (13 requests to www.youtube.com) with an introduction video. While youtube themself offer an iframe option called "Enable privacy-enhanced mode", the Gumb homepage embeds the »normal« iframe that places tracking cookies which again violates the GDPR.
The iframe furthermore sends
- 6 requests to
play.google.com/log, - 4 requests to
https://googleads.g.doubleclick.net - 1 request to
https://static.doubleclick.net - 4 request to
https://jnn-pa.googleapis.com
Tracking: The website uses, as stated in their privacy policy, Google Analytics (GA) which results in a request to https://region1.analytics.google.com/g/collect... and https://www.googletagmanager.com. However, writing "we use GA" in the privacy policy is not sufficient. GA requires consent from the website visitor.
There are a few more unnecessary requests, but I think the point is clear.
All of that is happening without any consent from the visitor!
Mobile App
Gumb offers mobile Apps for Android and iOS, of which I only checked the Android version. While I can't say for sure that the app violates the GDPR because it immediately asks for credentials, the Exodus Privacy Report (of the latest version 1.0.84) still looks rather bad:
- Amazon Analytics
- Amazon Mobile Analytics
- Google Analytics
- Google CrashLytics
- Google Firebase Analytics
- Google Tag Manager
Web App
Next to mobile apps, Gumb offers a web app too. Well, what can I say - there are requests to
https://fonts.googleapis.comhttps://www.googletagmanager.comhttps://region1.analytics.google.com/g/collect...https://www.google.de/ads/...https://stats.g.doubleclick.net/g/collect...https://ipgeolocation.io/
even without being logged in or any given consent.
Conclusion
For a tool from Switzerland with paid subscription plans and the purpose of managing events/meetings etc. it uses a lot of google (tracking) services... Very sad to see as the app looks otherwise really modern and useful. Do today's developers know that applications like Gumb can be implemented without selling their users' soul to google?
