Privacy Policy

What Readrail does with your data: nothing leaves your phone unless you decide so.

Publisher

Readrail is a teleprompter for Android published by byohan, trade name of Yohan Baechlé, entrepreneur individuel (sole proprietor), 7 rue du Moulin Saintin, 54200 Toul, France. Contact: contact@byohan.fr. Full details are in the legal notice.

In short

Readrail collects no personal data.

The app requires no account, shows no ads and contains no analytics or tracking tools. Readrail sends no data to byohan. Only the Google Play billing library, required for purchases, communicates with Google (see “Purchases”).

On your phone

Scripts
Your scripts, their history and the trash.
Settings
Text size, colors, pace, remote keys…
Statistics
Date, duration and pace of each rehearsal take.
Videos
The videos you record, saved in your gallery (Movies/Readrail folder), and their subtitles with Readrail Pro (Documents/Readrail folder).

This data only leaves your phone if you choose to: sharing, exporting a backup to a file of your choice, or Android backup (see below). Uninstalling the app deletes everything except the videos, their subtitles and the files you exported.

Permissions

Each permission is requested when you use the feature, never at launch.

Camera and microphone
Recording a video with the scrolling text. Nothing is recorded except the videos you start.
Microphone
Voice tracking: scrolling the text as you speak. Sound is neither recorded nor kept.
Overlay and notification
The floating window over other apps, and voice tracking while it is open.

Voice tracking

When the phone offers on-device speech recognition, it runs entirely on the phone, without a connection. Otherwise, Readrail uses the Android speech recognition service installed on the phone (often Google’s), which may process sound on its servers under its own privacy policy. In both cases, Readrail only receives the recognized text, uses it to follow your reading and does not keep it.

Phone remote

With Readrail Pro, a second phone can control the prompter. The two phones talk directly over your local Wi-Fi network, without going through the internet or any server. The prompter announces itself on that network under the phone’s model (for example “Samsung SM-S918B”), never under its personal name, and the four-digit code it shows must be entered to control it. Only playback commands (play, pause, paragraph, speed) and the playback state are exchanged, never the text of your scripts.

Purchases

Buying Readrail Pro goes through Google Play, which processes the payment under its own privacy policy. Readrail uses the official Google Play billing library for this: at launch, it checks with Google Play whether Pro was bought, and it may send Google technical information about how it works. Readrail only receives the purchase confirmation, kept on the phone to unlock Pro, even offline.

Android backup

If backup is turned on in Android settings, the system may copy Readrail’s data (scripts, settings) to your Google account, so you can restore it on a new phone. This backup is managed by Android, not by Readrail; you can turn it off in your phone settings.

Children

Readrail is not specifically aimed at children and collects no data, including theirs.

Your rights

Since Readrail collects no data, byohan holds no information about you. For any question, write to the contact address above. You may also contact your data protection authority (in France, the CNIL).

Changes

Any change to this policy will be published on this page, with its update date.
