This Privacy Policy describes how the Easy Blower mobile application ("the App", "we", "us") handles information when you install and use it on your device. By installing or using the App, you agree to the practices described in this policy. We have written this document in plain language so that you can clearly understand what we do — and, equally important, what we do not do — with your information.
Easy Blower is an offline utility designed to help you maintain and test the speaker on your iPhone through sound. The App generates audio locally on your device, records basic session information to your local storage so that you can review your usage history, and otherwise leaves your device and your data alone.
Let us be direct about this. Easy Blower does not collect, transmit, store, sell, rent, trade, or otherwise process any of the following categories of information:
In short, the App does not talk to us and does not talk to anyone else. Everything happens on your phone.
The App's core features — Speaker Cleaner, Air Blower, Frequency Generator, Speaker Test, and Noise Generator — all produce sound in real time using your device's built-in audio hardware. Audio synthesis is performed locally through Apple's AVFoundation framework. No audio waveform, sample buffer, or output stream is recorded, stored, uploaded, analyzed, or transmitted by the App.
The App does not access the microphone at any point. It only writes audio to the device's speaker output. Because the App does not request microphone permission, your conversations, surroundings, and ambient sounds remain entirely outside the App's reach.
When you complete a cleaning session, a speaker test, or any other playback activity that lasts two seconds or longer, the App saves a small record locally on your device. Each history record contains only the following fields:
This history is stored exclusively inside the App's sandboxed container using Apple's UserDefaults mechanism. It never leaves your device. You can view the full list at any time inside the App under History, and you can delete individual entries with the trash icon on each row or wipe the entire log from the Clear button in the navigation bar. Uninstalling the App also removes this data permanently.
Easy Blower is designed to require as few permissions as possible. Specifically:
The App is suitable for general audiences and does not target children under the age of 13. Because we do not collect personal information from anyone, there is no special category of data relating to minors that requires separate handling. If you are a parent or guardian and you believe a child has provided personal information to us through some other channel, please contact us at the email address below so that we can address your concern.
All data described in this policy is stored locally on your device using the standard iOS sandboxing model. That means the data is protected by the same operating-system-level isolation that protects your other apps, and it is removed automatically when you uninstall the App. We do not maintain any copy of your data on remote servers, which means there is no remote database for an attacker to compromise and no account for an unauthorized party to access.
We may update this Privacy Policy from time to time to reflect changes in the App, in applicable law, or in our practices. When we do, we will revise the "Last updated" date at the top of this document. If the changes are material, we will make a reasonable effort to notify you through the App or through the App Store listing before the new policy takes effect. Your continued use of the App after the effective date of the updated policy indicates that you have read and accepted the revised terms.
We encourage you to review this page periodically so that you stay informed about how we protect your information.
Because the App does not collect personal information from you, most data-protection rights — such as the right to access, correct, port, or erase data held by a company — do not apply in the traditional sense. However, you always have full control over the data that lives on your device:
If you have any questions, comments, or requests about this Privacy Policy or about the App in general, please reach out to us at the email address below. We read every message and we will do our best to respond in a timely and helpful manner.
