GDPR and its key elements to consider
The General Data Protection Regulation was introduced by the EU in 2016 and remains the primary thing to consider when thinking about the users’ privacy. This regulation has a strict focus on data collection and management as well as on the users’ rights in regard to their personal data.
You have to keep GDPR in mind even at the stage of prototyping and designing the UX/UI. For example, one of its primary elements is the user’s consent for the data collection. That means the user has to understand that the data is collected and understand the purpose of its collection.
Here are the main things to keep in mind when designing a GDPR-friendly mobile application.

Get informed consent from the user
Informed consent about the data collection means that the user is aware of it and agrees to share the data. In mobile apps, this regulation is usually under the “Terms and Conditions” or ‘Privacy Policy’ sections.
In order to do it right, you will need to follow the rules:
- Make the section extremely visible. It should not be written in a tiny and unclear font.
- Explain why you collect the data and how it will be used. For that, include a hyperlink to the corresponding page to the “Terms and Conditions”.

The user’s right to access the data and delete it
One of the GDPR’s primary statements is that users have their full right to access and manage their personal data that your company stores. In the “Data Policy” (or similar) section, explain how exactly the user can request and receive access to the data. For example, it may be the listing of the contact email or a company’s address. As well, explain the further steps that the user will have to take in order to access the data.
Another important right that the users have is the right to request a company to delete their personal data. Same as with the data access, explain how the users can get their data deleted from your database.
Things to remember:
- Make data-related sections visible.
- Ensure the user can easily find and navigate these sections.
A big mistake that many companies make
In an attempt to make the application more user-friendly and save a bit of the user’s time, some mobile developers pre-select the checkboxes for the users. Unfortunately, they tend to do so with the data collection boxes and this is another regulatory violation.
Remember what we said about the user’s consent for the data collection? By pre-selecting the checkbox, you are taking away the user’s right to agree to share their data. So when designing a mobile application, never pre-select any checkboxes and especially the ones that are related to the personal data collection.

Permission to access the user’s data
Another common case is when the application requests access for the user’s geolocation, camera, photo gallery, etc. While people are used to it (think about Snapchat as an example), there are still some rules to follow in order not to get in trouble.
First, always ask for the user’s consent. Before accessing the device, the application should always ask the user’s permission.
Second, ensure the app has visible sections on the data usage and management. This is similar to the points discussed above.
An obligatory practice that mobile developers should follow is not letting the app to access the device without permission. Instead, when the app needs access to a certain functional e.g. geolocation, it requests the user for it, thus, granting the user more control.
