This Privacy Policy explains how the BuildAlert mobile app (Android and iOS, package name uk.buildalert.app) collects, uses, and protects your information. BuildAlert ("we", "our", or "us") is committed to protecting your privacy.
The app uses the same BuildAlert account as our website. For how we handle data on buildalert.uk itself - including planning application data, billing, and letter sending - see our main website Privacy Policy. This page covers everything specific to the app: the device permissions it asks for and how it uses them.
BuildAlert is a platform that provides access to publicly available planning application data and allows users to identify potential construction opportunities and send marketing letters to property owners. The app is a native companion to our website, built for account holders to manage leads and letter templates on the go.
For the purposes of data protection law, BuildAlert acts as a data controller for personal data collected through the app.

Signing in on the app uses the same BuildAlert account as the website: name, email address, business name, and address. See the website Privacy Policy for full detail on this data.
Card and payment details are collected and processed directly by our payment provider, Stripe - BuildAlert never receives or stores your full card number. We do store a reference to your Stripe customer record, and a record of each transaction (credits purchased, amount, date, and transaction type) against your account, so we can show your purchase history and manage your subscription.
If you choose to upload a company logo, the app asks for access to your photo library so you can select an image. We only access the specific photo you pick - the app does not scan or upload your photo library in the background.
If you allow notifications, the app registers a device push token (via Firebase Cloud Messaging on Android, and Apple Push Notification service on iOS) so we can alert you about new leads and account activity. You can disable notifications at any time in your device settings.
If you enable Face ID or fingerprint sign-in, this is handled entirely by your device's own operating system. Your biometric data never leaves your device and is never sent to or stored by BuildAlert - the app only receives a yes/no confirmation that your device unlocked successfully.
To find and fix crashes, the app automatically collects crash reports, device model, operating system version, and app version through our crash reporting provider, Sentry. We do not send your IP address or any personal identifiers with this data. We use it only to diagnose and fix problems.
If you enable notifications, we store a push notification token, your device platform (iOS or Android), device name, and app version against your account, so we know where to deliver notifications. This is removed when you sign out or disable notifications.
The app does not request or access your device's precise or approximate location. Maps shown in the app display property addresses from planning application data, not your own location.
As on the website, the app gives you access to planning application information collected from publicly available local authority planning portals.
To provide your account, leads, and letter templates inside the app
To send you push notifications about new leads and account activity, if enabled
To let you attach a company logo to your letter templates
To diagnose crashes and improve the app's reliability
To process payments and manage your subscription
To respond to support requests
We do not sell personal data.
The app relies on the following third-party services:
Firebase / Google - delivers push notifications to Android devices
Apple - delivers push notifications to iOS devices
Sentry - collects crash reports and device diagnostics so we can fix bugs
Stripe - processes payments and manages subscriptions
Expo - our app development platform, used to build and deliver app updates
Printing and mailing providers - to post physical letters you create in the app
These providers only process data on our behalf and are required to protect it. We may also disclose information if required by law.
Depending on your device, the app may ask for the following permissions:
Photo library - to select a company logo to upload
Notifications - to alert you about new leads and account activity
Face ID / biometrics - as an optional, on-device sign-in method
The app does not request camera, microphone, contacts, or location permissions. You can review or revoke any permission at any time in your device's settings.
Account information is retained for as long as your account is active. Transaction records and records of letters sent are retained after account closure for as long as UK tax and accounting law requires us to keep them. Push notification tokens and device information are deleted when you sign out or disable notifications. Crash and diagnostic data is retained by Sentry for a limited period to support debugging, after which it is automatically deleted.
You can delete your account from inside the app under Settings → Delete my account, or use our web form at buildalert.uk/delete-account if you no longer have the app installed. See that page for what gets deleted and what we're required to keep.
Under UK data protection law you may have the right to:
request access to personal data we hold about you
request correction of inaccurate information
request deletion of your personal data
request restriction of processing
object to certain types of data processing
request transfer of your data
Requests can be made by contacting us at info@buildalert.uk.
The app is intended for business use and is not directed at children. We do not knowingly collect personal data from children.
We implement appropriate technical and organisational measures to protect personal data from unauthorised access, loss, misuse, or disclosure. Authentication tokens are stored securely on your device using your operating system's secure storage. However, no service can guarantee absolute security.
We may update this Privacy Policy from time to time. Any updates will be published on this page and the "Last updated" date will be revised.
