The author of these mobile applications is a developer operating under the name “dedo Libor”.
This document applies to the Ebook Voice Reader mobile app, published on Google Play under the “libcosenior” account. “dedo Libor” is the name under which the author presents the apps and website.
Ebook Voice Reader is used for reading books, documents, pasted text and web articles using Text-to-Speech, with optional text translation.
The app does not require creating an account and does not provide user registration. I do not request a user’s name, email address, or any login credentials.
The app developer does not directly collect or store on their own servers:
Book content and reading-related data, such as the book list, current position and voice settings, are stored locally on your device. Exceptions involving online TTS, advertising and Google Play services are described below.
The app may store the following information on your device so it can work correctly:
This data is stored in the phone’s memory or a local database. The developer does not receive it on their own server.
When a user shares a web page with EVR, the app connects from the device directly to the supplied internet address and attempts to load and extract the main article text. The operator of the visited website or its service providers may process normal technical data during this connection, such as the IP address, request time, page address and device or network-client information, under their own privacy policies. The EVR developer does not receive the article content or this technical data.
EVR uses Google ML Kit components for language identification and optional translation. The device may download the required language model from Google when a language is first used. After the model has been downloaded, language identification and translation run on the device; the text being translated is not sent to the developer. Model delivery may involve Google processing normal technical data under its privacy policy.
The free version uses Google AdMob to show a full-screen ad. The app enforces its own limit of no more than one displayed ad in any rolling 24-hour period, and an ad may be offered only after at least three completed reading or listening sessions. Ads are not shown during playback or to EVR PRO users.
The Google Mobile Ads SDK may automatically collect and share the IP address (which can be used to estimate approximate location), app interactions, diagnostic information, and device or account identifiers such as the advertising ID and App Set ID for advertising, analytics and fraud-prevention purposes. Data is encrypted in transit. The exact processing also depends on the user’s region and consent choices.
The app uses the Google User Messaging Platform (UMP) to obtain and manage consent where required. When required by UMP, users can later change their choice through Privacy options on the About the app screen. Depending on consent and availability, Google may provide personalized, non-personalized or limited ads.
A one-time EVR PRO purchase removes ads. Purchase, payment, ownership verification and purchase restoration are handled through Google Play Billing. The app receives the confirmation needed to activate PRO and stores it locally; the developer does not receive payment-card details. Google Play displays the current price and currency.
For more information about Google’s data processing, see the Google Privacy Policy and How Google uses information from partner apps and sites.
The app does not send book text or imported files to the developer. If a user selects an online TTS voice available on the device, the text intended for speech output may be processed by that TTS provider under its own privacy rules. The developer does not operate those TTS services and does not receive the book text.
The app may use certain system features of the device, for example:
These permissions are used exclusively for app functionality and not for collecting personal data by the app author.
The app is a general reading tool and is not designed specifically for children. It does not supply violent or sexual content and does not include gambling; users choose the documents they import.
The app does not require an account, and the developer does not store book content, documents, or user settings on their own servers.
Local data stored by the app, such as imported books, reading position, voice settings, pronunciation fixes, character fixes, or text skipping rules, can be removed by clearing the app data in Android system settings or by uninstalling the app.
If a user contacts us by email, they may request deletion of their email communication or data that is under our control.
Local app data may in some cases be included in Android/Google system backup depending on the user’s device settings. These backups are not managed by the app developer. Data processed by Google is managed through the user’s account settings, advertising-ID controls and Google’s policies.
This Privacy Policy may be updated from time to time, for example when new features are added or legal requirements change. The latest version will always be published on this page.
This site does not use first-party analytics or advertising cookies and does not include an external visit counter. It is hosted by Netlify, which may process technical server data such as an IP address, request time and browser type for security and page delivery under its privacy policy.
