TowerDub does not collect, transmit, or share any personal data — full stop. Everything you create stays on your device.
TowerDub requests microphone access solely to record samples in the Sampler and to mix a live input through the Delay and Reverb effects. Any audio you record stays on your device — it is never transmitted, uploaded, or shared with anyone, including the developer.
All your projects, patterns, sample recordings, and dub mixes are stored locally on your device. Nothing is synced to a server, because TowerDub doesn't have one.
TowerDub has no analytics, no advertising, no third-party tracking software, and no user accounts. There is nothing to opt out of, because nothing is being collected in the first place.
