BFF's own pages treat a screenshot of a profile as an ordinary thing to do. Its Privacy Policy notes that a member may recommend you to a friend. The member can do that by screenshotting your profile picture and sharing it, whether or not that friend is a member. What it bans is sharing sexual images, or screenshots of sexual conversations, without the consent of the person involved.

What the help center says

Three pages are worth knowing. BFF's Privacy Policy notes that a member can screenshot your profile picture. The member can share it with a friend as a recommendation, even if that friend is not on the app.

BFF's Community Guidelines draw a hard line. Obtaining, sharing or threatening to share sexual images or videos is prohibited without the consent of the person involved. The same goes for screenshots of sexual conversations.

And its page on reporting non-consensual intimate imagery lets you upload screenshots. They should show the profile belonging to the person sharing the content. The page also notes that BFF uses unique usernames.

So a screenshot sits in two different places. Sending a friend a picture of someone you think she should meet is a normal use. Sharing private or sexual material without consent is a violation, and a screenshot is also the thing you use to report it.

Will they know

Many men ask whether the other person finds out. BFF's help center does not say that members are notified when a profile is screenshotted. That is all it says. It does not promise that no one is told, so do not build a plan on the gap.

If you screenshot only for yourself, in a way you would be happy to explain, the answer to "will they know" stops mattering. The useful question is whether you would be comfortable if they did.

When a screenshot is fine

There are good reasons to take one.

You found someone who would get on well with a friend, and you want to introduce them. A screenshot of the profile picture is how BFF's own policy describes that kind of recommendation.

You want a record when something is wrong. If a person behaves badly, a screenshot of their profile and the conversation gives you something to hand over when you report them.

You want to remember a name or a detail before you reply. Saving a picture for your own use is the least risky of all.

When it is not

Do not screenshot a profile to mock it, post it in a group chat or send it around for a laugh. A woman or a man who joined an app to find company did not agree to be an example. BFF's guidelines are built to protect people from that sort of exposure.

Do not screenshot a private conversation in order to hold it over someone, and never threaten to share it. The Community Guidelines name threatening to share as a violation along with sharing itself.

And keep anything sexual out of a friendship app entirely. If a chat turns that way and you did not ask for it, report it and keep the evidence, and do not forward it to anyone.

Protecting your own profile

The same rule runs in your direction. Anything you put on your profile can be captured and passed on, because the policy says a member may share a screenshot of your picture. So put up nothing you would not want a stranger to forward.

Use a photo that looks like you on an ordinary good day. Skip anything with your home address, your workplace badge or other people's faces in it. Choose answers you would be happy to read aloud to a friend.

If you want less exposure, BFF's Privacy settings let you hide your age and your online status, and you can pause your profile completely. A paused profile is not shown to anyone new, so there is less of it to capture.

What it means for how you use the app

An app for finding friends works best when people treat each other as people, so use the same manners you would use in a club or a class. Be the person who says hello, makes a plan and turns up.

Friendships come from repetition. A man who goes to the same climbing class or board game night every week, learns three names and suggests a coffee gets further than one who collects profiles. The app is a way to start, and the plan to meet is what finishes the job.

The short answer

You can screenshot a BFF profile, and the app's own policy treats sharing a profile picture to recommend someone as ordinary. Keep it for introductions, for your own notes and for reports. Never use it to expose, mock or pressure anyone.
