Privacy Policy for Narro Reader
Last updated: July 5, 2026
In short: Narro Reader is a text-to-speech reading app. Your documents, reading progress, and most app settings stay on your device. We do not operate a cloud service that stores your books, PDFs, images, or clipboard content. When you use the mobile app with an internet connection, limited data may be processed by third-party services for advertising, analytics (with consent where required), crash reporting, and app updates.
This Privacy Policy explains how Gergely Kajtar ("we", "us", or "our"), the developer of the Narro Reader mobile application ("Narro Reader" or the "App"), collects, uses, shares, and protects information when you use the App on iOS or Android.
By using the App, you acknowledge this Privacy Policy. If you do not agree, please do not use the App.

Narro Reader does not require you to create an account. We do not provide user registration, login, or cloud storage for your reading content.
The core purpose of Narro Reader is to read content aloud on your device. In normal use:
We do not operate backend servers that receive or store the text of documents you read in the App.
This information stays on your phone or tablet unless you choose to share it outside the App (for example, by using the share sheet, exporting content, or opening a feedback form):
Some features need an internet connection. When you use them, data may leave your device as described below:
When you use the native iOS or Android App with internet access, we and our service providers may automatically process:
We do not intentionally collect special category data (such as health, political opinions, or religious beliefs). However, content you import into the App may contain sensitive information. That content remains on your device unless you choose to share it elsewhere.
The App may request access to device features so you can use reading features. You can deny or revoke permissions in your device settings, although some features may not work without them.
The free version of Narro Reader shows banner advertisements through Google AdMob.
When the App starts and your device is online, you may see Google's consent form for ads and related technologies. Depending on your region and choices:
On iOS and iPadOS, if ads are allowed, the App may request Apple's tracking authorization. If you deny tracking authorization, ads may still appear but are more likely to be non-personalized.
Ad providers such as Google may process advertising identifiers, device information, ad interaction data, approximate location derived from IP address, and similar ad-related data. On iOS, SKAdNetwork identifiers may also be used for ad attribution.
For more information, review Google's policies:
You can change ad and tracking choices by:
We use Google Firebase Analytics to understand how the App is used and to improve reliability and features.
Analytics is disabled unless consent rules allow it. When enabled, Firebase Analytics may receive events such as:
Some analytics events may include additional parameters. In particular, when you use the URL reader, the App may log the full URL you opened or attempted to open as part of an analytics event. URLs can sometimes contain personal or sensitive information. Analytics collection for these events follows the same consent rules described in Section 5.
Firebase may also receive a Firebase app instance identifier and a general language code user property when analytics is enabled.
Review Google's privacy documentation linked in Section 5 for details about Google's processing and retention.
We use Sentry to collect crash reports and application errors in production builds so we can diagnose and fix problems.
Sentry may receive information such as:
We use Sentry for app stability and debugging, not for advertising. We aim to avoid sending document text, clipboard content, imported file contents, or other user content in error reports, but errors may occasionally include incidental technical data from the App state.
Sentry is currently enabled in production regardless of advertising/analytics consent. Our lawful basis for this processing is our legitimate interest in maintaining and improving App reliability and security.

We use Capgo Capacitor Updater to deliver updated App bundles after the App has been installed from the App Store or Google Play. This helps us fix bugs and ship improvements between store releases.
When the App checks for updates, it may send:
Downloaded update bundles are installed locally on your device. This processing is necessary to provide and maintain the App.

If you are in Hungary or the European Economic Area, we rely on the following legal bases:
We use information to:
We do not use the App to send marketing emails, push notification campaigns, or promotional SMS messages.
Your information may be processed in Hungary and in other countries where our service providers operate, including the United States. Those countries may have different data protection laws than your country of residence.
Where required, we rely on appropriate safeguards such as provider contractual commitments and, where applicable, standard contractual clauses or equivalent protections offered by service providers.
Depending on where you live, you may have rights including:
Because most reading content stays on your device, deleting App data or uninstalling the App will remove locally stored documents and settings from your device, subject to your operating system behavior and backups.
To exercise your rights, contact us using the details in Section 18. We may need to verify your request.
If you are in Hungary, you may contact the Hungarian National Authority for Data Protection and Freedom of Information (NAIH). If you are elsewhere in the EEA, you may contact your local data protection authority.
The App is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided personal information through online services we control, contact us and we will take appropriate steps to delete such information where required.
We use reasonable technical and organizational measures designed to protect information. However, no method of transmission over the internet or electronic storage is completely secure, and we cannot guarantee absolute security.
Because your documents remain on your device, you should also protect your device with a passcode, biometrics, or other security controls.
The App may open third-party websites or services, including web pages you request in the URL reader, feedback forms, app store pages, and content delivery networks. We do not control those third parties and are not responsible for their privacy practices. Review their privacy policies separately.
We may update this Privacy Policy from time to time. When we do, we will post the updated version on this page and change the "Last updated" date above. Material changes may also be communicated through the App or our website where appropriate.
Your continued use of the App after an update means you accept the revised Privacy Policy.
