I received an e-mail from Facebook that i need to include a privacy policy in my Facebook tab. I thought privacy policy's were only needed in Facebook Apps.
Were can i find an example of a privacy policy?
Simply put, the reason for Facebook's strict requirements are mostly because of them wanting to demonstrate that they do everything to educate their users "we told the user to have a privacy policy". Therefore you receiving that email may not necessarily be related to you doing anything related to privacy.
In theory it's still possible to gather data from a tab/page with input forms.
iubenda has been specialising in this kind of problem with a dedicated privacy policy generator for Facebook apps and a hosting service for privacy policies built in: http://iubenda.com/facebook/
There's also a basic free version to be had for the general privacy policy here http://iubenda.com (edit: I haven't pointed out that the free version only works for web policies, as commented on by one user)
(disclosure: I work with the iubenda team to keep this being the best possible tool out there)
