Description

Dating Privacy aims to contribute with data literacy and gaining control over personal information in a secured and ethical manner for end users.

This collective is a social movement we have started after identifying several privacy risks we, as dating app users, are confronted with when looking for a date online: unwanted ads, harms resulting from incorrect profiling and predictions, the possibility of phishing and identity theft.

Dating Privacy is a collective formed by members coming from different countries and disciplines (mathematics, sociology, journalism, law, physics) and foreparts (academia, private, independent, citizen NGO).

Objectives

  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

Recommended practices

  1. Start requesting your data via this link https://labs.letemps.ch/interactive/2020/demander-ses-donnees/
  • Type in the box the dating app name you use
  • Copy-paste the message and email address
  • Send it and wait for your file
  1. Already requested your data and received a file? Contribute with the wiki and map what your dating app collects: https://wiki.personaldata.io/wiki/Item:Q3569
  2. Are you an Android phone user? Download Exodus Privacy helps you to know which trackers and permissions are embedded in dating apps installed on your device.
  3. Configure your privacy settings on your dating app.
  4. Check out Mozilla privacy test on different dating apps
  5. Request deleting your data on a dating app when you stop using the app via the settings or sending an email. It is not enough to uninstall the app

Problems Identified

APP

  1. Subscription rates change according to user demographic characteristics (ex. age on Tinder, sex on Hinge). Prices are invisible outside the app
  2. Sharing personal data with third parties which is not necessary for the app functioning (ex. for advertisement, see The Grindr case study) and for other purposes unknown (ex. the muslim app providing data to the american army)
  3. Background geolocation when the app is closed
  4. Automatic subscription renewal without notification, when there is a problem you have to contact the headquarter in another country
  5. Fake profiles created by the company (ex. ashley madison, Lovoo), buying profiles
  6. 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? Are users retained in the app?
  7. The app ignores settings for presenting results (ex. show me only women and the user sees men)
  8. Users are banned without any reason given by the app
  9. One user said it has zero matches on Tinder
  10. Data leaks because of security breaches, the app did not protected the data properly

Other USERS

  1. Scams, phishing, fake profiles. Users are affected by malicious user behaviours so how are dating apps moderating this and protecting users via the analysis of their personal data?
  2. Rape and harassment: when "unmatching" on Tinder, the conversations and the profile are deleted for the victim. The victim loses the data to report, see https://pages.rts.ch/emissions/temps-present/11994345-le-camp-de-la-honte-aux-portes-de-leurope-08-04-2021.html?anchor=12111124#12111124
