Effective Date: March 17, 2026
Tower Drill ("the App") is developed and maintained by Tower Drill. We are committed to protecting your privacy. This policy explains how we handle information when you use our iOS application.
Tower Drill does not collect, store, transmit, or share any personal data.
Specifically, the App does not collect:
Tower Drill uses on-device speech recognition to evaluate your radio communication responses. All speech processing happens entirely on your device. No audio recordings or transcriptions are transmitted to any server, including our own.
The App uses an on-device language model to provide coaching and feedback. This model runs entirely on your iPhone. No prompts, responses, or training data leave your device.
Tower Drill offers an optional in-app purchase processed entirely by Apple through the App Store. We do not have access to your payment information, Apple ID, or purchase history. Apple's handling of purchase data is governed by Apple's Privacy Policy.
Tower Drill does not integrate any third-party analytics, advertising, tracking, or social media SDKs. The App does not contain any advertisements.
Your lesson progress and app preferences are stored locally on your device using standard iOS storage mechanisms. This data is not accessible to us and is not transmitted anywhere. It is included in your standard iCloud or iTunes device backups if you have those enabled.
Because Tower Drill does not collect any data from any user, it is safe for users of all ages. We do not knowingly collect personal information from children under 13 or any other age group.
If we update this privacy policy, we will post the revised version on this page with an updated effective date. Since we do not collect email addresses or contact information, we encourage you to review this page periodically.
