The dating app Christian Connection is considering whether its members would want to see other users' vaccination status on their profile.
Opinions range among users, with some thinking it would be a good way to stay safe from Covid while meeting up, and others thinking it infringes their privacy.
Secular dating apps have already teamed up with the Government and the NHS to allow users to show their support for the vaccine on their dating profiles and give in-app bonuses to those who say they are vaccinated recently.
Tinder, Hinge, Bumble and Muslim dating site Muzmatch have all started collaborations with the vaccine campaign.
Features include vaccination badges and stickers to display on their profile, free 'likes', and other boost-type features.
Users will also start seeing adverts for the 'every vaccination gives us hope' campaign.
The Department of Health and Social Care said providing vaccination status on these apps is optional, but added that data has shown that people are more likely to date someone who has had a Covid-19 jab.
Christian Connection has done a survey of their members to see what they would prefer. Nearly 40 per cent are in favour but nearly a third of responders are opposed.
Jackie Elton, founder fo Christian Connection, told Premier: "We still haven't made up our mind. What the survey indicates is that a majority either think it's a really good idea or are very open to the idea and will probably use it, but then there is probably about 30-32 per cent who feel pretty strongly that they will be very unhappy."
Elton said they are taking all views into account and any addition would be optional, like adding that you are a vegetarian or a smoker. Nearly half of members, when asked, said they would display their status if it was an option, but again nearly a third said they definitely would not.
She added that another reason for providing the option would be that it gets the conversation out the way and avoids any debates about the vaccine on the actual date. Results of the survey suggest that a lot of people would find it useful simply to understand more about someone's beliefs, as well as the safety factor.
Jackie Elton added, however, that people do not usually ask someone if they have had the flu vaccine, so it might seem too personal for some single people meeting for the first time.
"I think it's something that we will have to discuss and look at the survey and decide whether this is the right thing to do. Sometimes we trial things and see if it's a good thing to do. It's never easy - any feature we add on Christian Connection we take very, very seriously indeed."
