"Dating Privacy" is a collective contributing to take control of personal data and to data literacy in a secured and ethical manner for end users and research purposes.

It is comprised of members coming from different countries, disciplines (mathematics, sociology, journalism, law, physics) and foreparts (academia, private, independent, citizen NGO).

Meetings online at https://epfl.meet.switch.ch/dating-data
Every first Wednesday of the month at 20h15
Meeting Notes https://docs.google.com/document/d/1Co_ccRQf1tidcZpO2MVcvWCVnvaR0fCEEW2IPLpZ-q4/edit?usp=drivesdk

  1. Implement tools that allow users to request and analyse their data
  2. Find and ask for SAR with a concrete example and cooperate with communities in order to 1 increase the impact 2 relay the info
  3. Enrich the wiki with data structures extracted from the SARs
  4. Develop methodologies that allow for research without dependency on commercial platforms
  5. Formalize the working group and project with an official legal entity

Problematic Proposals

  1. Sharing personal data with third parties which is not necessary for the app functioning. The Grindr case study. Check third-parties that are the biggest players
  2. Sexual harassment
  3. Scams, phishing, fake profiles
  4. Users are affected by malicious behaviours 1 and 2 so how are dating apps moderating this and protecting users via the analysis of their personal data?
  5. Between 10-20% of users find a partner in France, Switzerland and United States. Do users really get the outcomes they want from the app in exchange for providing their data?
  6. Subscription rates changing according to user demographic characteristics (ex. Tinder)

TO DO / On going

Map the ecosystem
How many apps are available? Maybe be restricted to Europe.

  1. Digital methods project "Mapping data ecologies of the dating industry" https://docs.google.com/presentation/d/1n-p_efBmkK2v1KGCbHyHb_csmR6D7KN8SX3qron9Cn4/edit
  1. Tools to sample how many apps are in the Google and Play stores:

"Google Play Store Scraper" is a simple tool to extract the details of individual apps, collect their related apps, retrieve app permissions, and retrieve a list of apps for a given keyword.
"iTunes App Store Scraper"

Permissions per app via Exodus
List apps per ranking, add ranking to every app following the table in the google doc
Archive Privacy policies
Add link to privacy policy
Defining the project scope

Dating apps' list

  • Wiki
