UNextBridge is a free Android app that warns drivers of low bridges and other low structures ahead on the road. It is published by Eontar Technologies Ltd, United Kingdom ("we"). This page covers only UNextBridge.
Your location. The app asks for permission to use your precise location, including while the app is in the background (for example while you drive with the screen off), because the warning must work while you drive. Your phone sends your position, direction of travel and speed to our server at short intervals so that the server can find low structures within a few kilometres ahead of you and on roads you could turn onto, and send back only those. We do not store your location history, do not build a route or movement profile, and do not link locations to you. Position data is used only to answer the request and is then discarded; short-lived technical logs (for example, errors) contain no position. Location permission is required for the warnings: without it the app cannot warn you.
Your vehicle height. The height you enter is saved on your phone and is sent with each request so that only relevant structures are returned. It is not stored on our server.
Random install code. To stop automated copying of our data, the app uses a random install code (not your name, email or advertising ID). It is used only to limit the number of requests and is not used to identify you.
Settings on your phone. Language, theme, units (metres or feet) and your vehicle height are saved only on your phone.
Accounts. UNextBridge has no accounts. We collect no name, email address, phone number, contacts, photos or payment data.
Advertising. The free app may show ads from Google AdMob (two banners). Ads are switched off during the first six months after public launch. When ads are on, Google and its partners may use your device's advertising ID, your IP address and basic device information to show and measure ads. Where the law requires it (UK, EEA, Switzerland), the app asks for your consent first through Google's consent form, and you can change your choice at any time in Settings > Privacy > Ad privacy choices (shown where Google requires it). You can also reset or delete your advertising ID in your phone settings. How Google uses data from apps that use its services: https://policies.google.com/technologies/partner-sites
Data sources. Structure information comes from OpenStreetMap contributors (© OpenStreetMap contributors, Open Database Licence) and other public sources.
We do not sell personal data. We do not share your location with advertisers: Google receives only the data described under Advertising, and only when ads are on and, where required, you have consented.
Your location is not kept (see section 1). Advertising data is held by Google under its own policies.
Under UK GDPR and EU GDPR you can ask for access to, correction or deletion of personal data we hold about you, object to processing, and withdraw consent at any time. Because we hold no account and no location history, we normally hold nothing that identifies you. To withdraw ad consent use Settings > Privacy > Ad privacy choices or your phone's advertising ID settings. You may also complain to the UK Information Commissioner's Office (ico.org.uk).
UNextBridge is not directed at children under 13 (or under 16 where local law requires) and we do not knowingly collect their data.
Warnings are for reference only. The data may be incomplete, wrong or out of date, and a missing warning does not mean a road is safe. Structures without a recorded height are not guaranteed to be high enough. The driver remains fully responsible for the route and the vehicle; always follow road signs and the actual height markings. To the extent the law allows, we accept no liability for damage caused by relying on the app.
We will update this page and its date when something changes. Material changes will also be announced in the app description.
