Privacy policy

Last updated: 8 November 2026

This policy explains what personal data Wreckfinder Limited ("we", "us") collects when you use the Wreckfinder app, web app and website, why we use it, and your rights. We are the data controller for this data under UK data protection law (UK GDPR).

What we collect

Account details: your name and email address when you sign in with email, Google or Apple.
Subscription details: whether you have Premium, your plan, and when it renews or expires. Payments are handled by Google Play, the App Store or Stripe. We never see your full card details.
Your saved wrecks: the wrecks you add to favourites.
App usage: which screens and features are used, linked to a random ID for your app installation, along with your device type, app version and whether you have Premium. This doesn't include your name, email address or GPS position. You can turn it off at any time in Account > Share usage stats. We also keep a notification token if you allow notifications.
Messages to us: support chats, emails and feature suggestions you send. If you chat with Dusty on our website, we keep your messages, and the email address if you give one, so Sean can reply. While you use the website chat, a random ID is kept in your browser so your conversation carries on from page to page; it is only created if you open the chat. The website also notes, until you close your browser, whether Dusty has already offered to help, so he doesn't ask twice. We don't use advertising or tracking cookies on the website.
Your location: if you allow it, the app uses your phone's location to show your position and the distance to wrecks. This is worked out on your phone and is not stored on our servers.
Marketing choice: whether you have opted in to "Tips & news".

Why we use it

To provide the app and your Premium features (to perform our contract with you).
To answer support requests and improve the app (our legitimate interests).
To send occasional tips and news, only if you opt in (your consent, which you can withdraw at any time in the app).
To keep payment and tax records (legal obligation).

Who we share it with

We use trusted service providers to run Wreckfinder. They only use your data to provide their service to us:

Clerk (sign-in and accounts)
Supabase (our database)
Google Play, Apple App Store, RevenueCat and Stripe (payments and subscriptions)
Google Maps (the map)
Google Analytics for Firebase (app usage statistics)
Brevo and Zendesk (customer support records and emails)
Anthropic (powers the AI assistant in our support chat; your chat messages are processed to generate replies)
Expo (app updates and notifications)

Some of these providers are based outside the UK. Where data is transferred abroad, it is protected by approved safeguards such as standard contractual clauses. We never sell your data.

How long we keep it

We keep your data while you have an account. If you delete your account we remove your personal data within 30 days, apart from backups (up to 90 days) and payment records we must keep by law.

Your rights

You can ask to see, correct or delete your data, object to how we use it, or ask for a copy. Email [email protected]. You can also delete your account. If you're unhappy with how we handle your data, you can complain to the Information Commissioner's Office at ico.org.uk.

Children

Wreckfinder is not intended for children under 13, and we don't knowingly collect their data.

Changes

We'll post any changes on this page and update the date at the top.
