Common questions about SocialAppFix
Is SocialAppFix part of Facebook, Meta or any other app?
No. SocialAppFix is an independent guide. We’re not affiliated with or endorsed by any platform, and we can’t see or change anyone’s account. For account decisions we link you to the official help routes.
Will you ever ask for my password or a login code?
Never. No real support service needs your password or login codes. If anyone asks for them — including people claiming to be "support" — it’s a scam. Read our guide to spotting recovery scams.
Can SocialAppFix recover or unlock my account?
No one outside the platform can. Our guides show you the exact official recovery or appeal route, and how to avoid paid "recovery" services that can’t deliver.
Is it free?
Yes. Every guide is free to read, with no sign-up.
