Figure 5
Acceptability of hypothetical tracking technologies and numbers of Corona-Warn-App downloads. For the hypothetical scenarios, the first column displays baseline acceptability ratings; the other two columns display acceptability under varying conditions: with the requirement that all data be deleted and tracking stopped after 6 months; with an “opt out” option (severe scenario); and with data being stored locally on the user’s phone (mild scenario). For Corona-Warn-App usage, the data show current downloads and intentions to download. Error bars are 95% confidence intervals computed by R function prop.test. Full results are reported in Supplementary Table A4. For items, see Supplementary Table B5; for descriptions of scenarios, see Supplementary Table B4.
