Can I build an iPhone app that generates cryptocurrency income without the user&#39;s consent or knowledge?
<p>I had an idea of an iPhone app but I'm not sure if the methods are entirely legal. For that reason I thought I would come here to ask.</p>
<p>Where I live, in Canada, it can get pretty cold. Hence, I had the idea of making the iPhone heat up slightly (to a safe level) so the user could heat up their hands and to prevent the phone from shutting down to the cold temperatures (a common problem in the winter).</p>
<p>To do this I had the idea of running a cryptocurrency miner on the device. For those who don't know, cryptocurrency mining can be a CPU-intensive process and can cause it to heat up, but the process can also generate cryptocurrency that can be exchanged for other currencies (CAD, USD).</p>
<p>Would it be illegal to use this method to heat up the phone if the user is not told how the phone is heated up as it generates an income that they would not receive?</p>

<p>The most important thing to realize is that such an App will probably never be accepted into the Apple App and/or iTunes store if you submit it without the mining disclosure in the end user's TOS.</p>

<p>Apple reserves the right to accept or decline any App in the App store; they will evaluate your App after you submit it, and when they find the crypto mining aspects and see that they are not clearly stipulated in the user's TOS, they will probably not accept your App. Apple will find that you attempted to conceal an App "feature" that involves user security, i.e. the mining software will communicate in secret from the iPhone to a mining hub or account under your control without the user's knowledge.</p>

<p>Even if your App did make it into the store, chances are good someone will see their iPhone connect with the mining software and investigate. Even if you do disclose the miner in the TOS, Apple can decide to remove your App from the store.
