Here’s my take on this.
It’s a tricky situation because when you delete a Tinder account, the action is usually permanent on their servers, especially after a month has passed. Your matches and chat history are typically wiped from their end for privacy and data management reasons.
On one hand, your only official route is contacting Tinder support directly. You can explain the situation, but given their stated policies, the chances of a successful recovery are slim. Still, it’s the only direct channel you have.
On the other hand, the most probable outcome is that you will need to create a new account. I know this isn’t ideal as it means a fresh start without your previous connections. As for local recovery on your iPhone, since most of the critical data is stored server-side, phone data recovery tools are unlikely to restore the account itself.
