Honest answers
How can I see deleted Facebook Messenger messages?
Install Nail It and allow notification access. From then on every Facebook Messenger message that reaches your notifications is saved on your phone. If the sender later uses "Unsend for everyone", the message disappears from Facebook Messenger but stays in Nail, marked "they deleted it", and Nail sends you an alert.
Does it work without root?
Yes. Nail It only reads Android notifications. No root, no access to Facebook Messenger's database, no Accessibility service, no account.
Does it capture every Facebook Messenger message?
No. It is a notification history: messages that never produced a notification (muted chats, a chat open on screen, messages read on another device, a collapsed "999 messages" summary) are not captured. Nail says so honestly.
Can I see what a Facebook Messenger message said before it was edited?
Yes. Facebook Messenger lets senders edit within 15 minutes. Nail detects the edit, keeps every version with the time it was seen, and shows the original struck through under the new text.
What about photos, voice notes and videos?
Images attached to notifications are kept. With Media Rescue switched on, Nail also copies photos, videos, voice notes, stickers and documents from Facebook Messenger's media folder the moment they arrive, so a delete cannot take them back.
Is my data safe?
Everything stays on your phone. Nail has no accounts, no cloud, no analytics on your messages. Its only connection is a daily check of this site for a new version, and you can switch that off.
