How much notice do I need to give for a change in privacy policy?

You need to give advance notice for any substantive or material changes to your privacy policy. The amount of notice depends on the type of change you are making.

For notices of upcoming substantive or material changes, it’s best to let users know a couple of weeks in advance to give them time to adjust their privacy preferences if needed.

While not always required, it is good practice to actively notify users of changes that may not constitute substantive or material changes alone but which together constitute an important update to the policy (whether in substance, style, or format). For notice of important updates that are not substantive or material, notice closer to, on, or immediately after an update may be appropriate.
