This is the privacy policy for my TTS Util Android app. It details my policies concerning the collection, use, transfer and disclosure of personal or personally identifiable information.
TTS Util does not collect any personal information. All information entered into or otherwise used by the app is kept on the device and is not transmitted.
Furthermore, the read/write storage permissions the app asks for are required only for being able to read selected files with text-to-speech or write synthesised speech into a new wave file.
Log data is collected in the case of errors in the app, such as crashes or situations where the app stops responding. This log data may include information such as your device’s Internet Protocol (“IP”) address, device name, operating system version, app configuration when the error occurred, the time and date of the error occurrence, the stack trace, and other statistics.
The TTS Util app passes text to the selected text-to-speech engine in order to synthesise it into audible speech. Text-to-speech engines may or may not retain this data after finishing with it. Please see the privacy policy of the selected text-to-speech engine for more information.
Log data collected from the app is useful in diagnosing why errors occur and will help to improve the experience of using the app overall. However, reporting errors is completely voluntary and you are free, of course, to not report errors when prompted after an app crash.
Data collected by the text-to-speech engine via TTS Util should only be used for synthesising text into audible speech, although the TTS Util app has no control over what the TTS engine package actually does with this text. Please see the privacy policy of your selected text-to-speech engine for further information.
You can see which TTS engine you're using by navigating to your device's text-to-speech output settings, typically under Settings -> Accessibility -> Text-to-speech output.
Data processed by the selected text-to-speech engine may or may not be disclosed to outside parties. Once again, the TTS Util app has no control over this.
If the privacy of input text is very important to you, then Pico TTS, which is usually distributed with devices, only seems to require network access for downloading the initial models required for text synthesis. CMU Flite is another open source alternative that works like this.
If there are any policy changes they will be posted on this page.
If you have any questions, complaints or suggestions concerning my privacy policy, please do not hesitate to contact me.
