Selling ex-device with metamask associated safely?

Hi everyone,

I am an iOS user and have installed metamask app on my phone. I now have changed it, and was able to set up metamask in my new device with no problem at all.

Nevertheless, I was wondering if I have deleted/erased completely my accounts/wallets config from the older device… I have made a full restore on it, and my question is: is it safe now to sell it or give it away? There is no way of reaching to my funds from that older device?

It may be a silly question, but I would like to confirm my guesses that there is no way to reach to my metamask info from that older device.

Thanks in advance,
