 Some data can reveal more information about an individual than others. Only use an extensive or detailed data collection method, if you also use this type of data to answer your research question. Some data can reveal more information about an individual than others.

 Photo, video or audio files might contain a timestamp, date and depending on the equipment and settings also location. Check whether you can prevent the collection of these data or remove these metadata as soon as possible after collection. [[https://www.comparitech.com/blog/vpn-privacy/exif-metadata-privacy/|Comparitech]] shows an example of EXIF metadata stored with a photo, including the GPS coordinates where the photo was taken and a timestamp of when the photo was taken. These metadata, included in smartphones or digital cameras, can help catalogue photos (e.g. Google Timeline) but can also result in privacy risks in the context of research.  Photo, video or audio files might contain a timestamp, date and depending on the equipment and settings also location.

 Participants often share more information than necessary when asked open-ended questions. If possible, provide predefined options instead. For example, asking “Where are you from?” may result in participants revealing their home address or city when only their country of residence is required. Providing examples or limiting responses to a question reduces the amount of personal data collected.  Participants often share more information than necessary when asked open-ended questions.

 Do not collect contact information if you do not plan to contact your participants after you collected the data (e.g. in case of recruitment via social media, posters or third parties). The [[https://www.rug.nl/digital-competence-centre/it-solutions/collect-and-annotate/qualtrics-surveys?lang=en|UG approved survey tool Qualtrics]] provides the option to use an [[https://www.qualtrics.com/support/survey-platform/distributions-module/web-distribution/anonymous-link/|anonymous link]] to prevent the collection of name and e-mail address of your participants.  Do not collect contact information if you do not plan to contact your participants after you collected the data (e.g. in case of recruitment via social media, posters or third parties).

 Online (survey) tools sometimes automatically register personal data, such as IP addresses. Check whether it is necessary and possible to turn off automatic data collection in your online data collection tool. Counterintuitively, when using an anonymous link, Qualtrics still automatically registers IP addresses, which can reveal someone’s location and identity. If you are not using these IP addresses for your research, make sure to enable [[https://www.qualtrics.com/support/survey-platform/survey-module/survey-options/survey-protection/#AnonymizingResponses|Anonymize Responses]] in the survey options as well.    Online (survey) tools sometimes automatically register personal data, such as IP addresses.

 If you are [[https://www.rug.nl/digital-competence-centre/guides-faq/checklist-social-media-data.pdf|scraping or manually collecting data from social media platforms]], you might not directly collect contact information. However, posts are often accompanied by social media ID and post ID. This information is very easy to trace back to an individual. If you do not need this information for current or future research (e.g. connect to other datasets), delete these IDs from your dataset or consider pseudonymization. If you are [[https://www.rug.nl/digital-competence-centre/guides-faq/checklist-social-media-data.pdf|scraping or manually collecting data from social media platforms]], you might not directly collect contact information.
