# Can I use transformations to anonymize data for client-side destinations?

You can use [transformations](/admin-panel/transformations.md) to delete a property before it's sent to a client-side destination, but we don't support a way to anonymize client-side events. This is because destinations loaded client-side will already have access to a user's IP address, at which point it is no longer possible to truly anonymize that user.

If you want to anonymize a user, you should use [ID Masking](https://documentation.freshpaint.io/hipaa-mode#id-masking) with the destination configured in server-side mode.
