What a dating app knows about you, and where it goes

There is a short answer about dating app privacy and a useful one, and they are not the same. What follows is the useful one.

The categories you are handing over

A dating profile typically contains your face, your location over time, your sexuality, your relationship intentions and often your religion, health or political views. Several of those fall into the special categories that data protection regimes in many countries treat as requiring extra protection. Message content, photographs sent privately, and the times you are active are all held as well.

None of this is hidden; it is simply not what people are thinking about while writing a bio.

Deactivating is not deleting

Hiding a profile removes it from other users and generally leaves the account and its data intact on the company's systems. Deletion is usually a separate action, sometimes buried, and often subject to a grace period during which it can be undone.

Retention after deletion varies by company and by jurisdiction, and the privacy policy is the only reliable source for the one you use. In many countries you have a legal right to request deletion and a copy of your data, and the process is normally a form rather than a fight.

Where the data travels

Advertising and analytics components inside apps have historically shared identifiers and behavioural data with third parties, and regulators in several countries have taken action over it. The situation has improved under newer rules and it varies significantly by platform and by region. Anything shared with a third party has its own retention and its own breach risk, which is why the total exposure is larger than the app itself.

Reading the privacy policy of the specific app is dull and is the only way to know rather than assume.

The realistic threat is other users

Screenshots, saved photos and forwarded messages are the most common way private material leaves a dating app, and no setting prevents them. A first name, a workplace and a couple of photos are usually enough to find someone's other accounts, which is why so many people are located by matches. Ephemeral or view-once features reduce casual sharing and do not stop a second phone photographing a screen.

The only reliable control is deciding what you send, not what the platform promises about it.

Sensible reductions

Using photos that do not appear on your other public accounts breaks the easiest link between profiles. Keeping your employer, your street, your gym and your children out of photos and bios removes the details most often used to find people.

A separate email address, and where possible a number that is not your main one, limits what a match can search. None of this is paranoia; it is the same reasoning as not printing your address on a shop noticeboard.

Every relationship is its own thing, and general advice only goes so far.

If something goes wrong

Non-consensual sharing of intimate images is a criminal offence in a growing number of countries, and specialist helplines exist that can request takedowns on your behalf. Reporting to the platform and to the police are separate steps and both are worth taking, keeping copies of evidence first. Blackmail based on images is a well-known crime pattern; paying reliably leads to further demands, and law enforcement in most countries has seen it many times before.

None of it is your fault for having trusted somebody, and support organisations say this to people every day.

The takeaway

Assume anything you send could be saved by the person receiving it, and keep the identifying details off the profile.

Say the awkward sentence early. It is cheaper than the alternative.
