We found these ways of contacting the developers:

Do your own research!

Try out searching for "lost bitcoins", "stole my money" or "scammers" together with the wallet's name, even if you think the wallet is generally trustworthy. For all the bigger wallets you will find accusations. Make sure you understand why they were made and if you are comfortable with the provider's reaction.

The Analysis

TronWallet uses advanced security mechanisms that completely protects the user’s private keys, and makes private keys and sensitive data available only on the user’s specific device, utilizing the latest military-grade technology for encryption.

and

No third party, including TronWallet, can access your private keys or restrict any transaction the user decides to make.

are clear statements of this app being a non-custodial wallet.

* No fees - Yes, that’s right - send and receive is free

This is a suspicious claim as Bitcoin transactions cannot be sent for free any more.

* Your keys are yours and PRIVATE to you alone - YOU truly own your crypto

and

IMPORTANT NOTE REGARDING SECURITY AND PRIVACY:
* Your Private Key is stored encrypted on your smartphone. It is never shared or sent anywhere. Nobody at the TronWallet organization can access your private key.

They really care to stress this point :) Let’s see if we can verify this claim.

So their website as registered in Google Play forwards us to this website which has a link to download another Bitcoin wallet: Klever: Bitcoin Blockchain Wallet.

As the website is not about the app, the Google Play description does not point to any source code and neither can we find a relevant project on GitHub, we assume this app is closed source and thus not verifiable.

Verdict Explained

No source code found Without public source available, this app cannot be verified!

This verdict means that we could not find any source to compile the app from. Internally the company might do everything right but as we can't verify it, there is nothing protecting the user from an exit-scam where the provider releases an app that leaks the keys to the servers.

The app cannot be independently verified. If the provider puts your funds at risk on purpose or by accident, you will probably not know about the issue before people start losing money. If the provider is more criminally inclined he might have collected all the backups of all the wallets, ready to be emptied at the press of a button. The app might have a formidable track record but out of distress or change in management turns out to be evil from some point on, with nobody outside ever knowing before it is too late.
