Facebook will not use personal data to show ads to one person. A woman named Tanya O'Carroll asked Facebook to stop doing this. She lives in London and works with tech and human rights. She says this will help other people who do not want ads based on their personal data.

Tanya made a Facebook account 20 years ago. She did not like how Facebook used her data to show ads. When she was pregnant, she saw many baby ads. She felt this was not right. She asked Facebook to stop using her data for ads.

The UK has rules about how companies use personal data. Tanya said Facebook's ads are like direct marketing. The UK data office agreed with her. Facebook said they do not show ads to just one person. But they agreed to stop using Tanya's data for ads. Tanya hopes this will help other people too.
