In short: Companies House Check has no accounts, no advertising and no tracking. Your saved companies, lists, notes and alerts stay on your device. We only process what is needed to look up public company information and to manage your subscription.
Companies House Check ("the app", "we", "us") is published by Chaptio. For any privacy question contact support@chaptio.com.
Companies House Check is an independent app. It is not made by, endorsed by or affiliated with Companies House or the UK Government.
The following is stored locally on your iPhone or iPad and is never sent to us:
You can delete all of it at any time in More › Delete all saved data, or by deleting the app.
| What | Why | Who |
|---|---|---|
| Search terms, company numbers and officer IDs you look up, plus the technical data any web request carries (IP address, device type, time) | To fetch public register data from the official Companies House API through our server. Public register responses are cached on our server to make the app faster; the cache contains company data, not information about you. | Our server (Chaptio), Companies House API |
| For alerts: the company numbers you monitor and the searches you save | Your device sends these to our server when it checks for changes. We do not keep a list of what each user monitors. | Our server |
| Subscription status: an anonymous app user ID, purchase and renewal events, country and price | To unlock CH Check Pro, restore purchases and support refunds. | Apple, RevenueCat Inc. (subscription management) |
| Messages you send us | To answer support requests. | Chaptio |
Server logs are kept for up to 30 days for security and troubleshooting and are then deleted.
Purchases are handled by Apple. We never see your card details. RevenueCat processes an anonymous identifier and your purchase receipts on our behalf so the app knows whether CH Check Pro is active. See Apple's privacy policy and RevenueCat's privacy policy.
If you allow notifications, alerts about companies you follow and reminders before filing deadlines are created on your device. We do not use push-notification tokens for marketing.
Companies House Check displays information published on the Companies House public register, which includes personal data about company officers and persons with significant control, such as names, month and year of birth, nationality and correspondence addresses. Companies House publishes this information under the Companies Act 2006 and the Open Government Licence v3.0.
We show this information as it appears on the register and do not add to it. If you want information about you on the register to be corrected, suppressed or removed, please contact Companies House, which controls the register. Once it changes there, Companies House Check shows the updated record after our cache refreshes, normally within 24 hours. You can also contact us and we will clear our cached copy straight away.
RevenueCat and Apple may process data outside the UK. Where they do, transfers are protected by the UK International Data Transfer Addendum or equivalent safeguards.
You can ask to access, correct or delete personal data we hold about you, object to processing or ask us to restrict it. Because most data stays on your device, the quickest way to delete it is Delete all saved data in the app. For anything else email support@chaptio.com; we reply within 30 days. You may also complain to the Information Commissioner's Office (ico.org.uk).
Companies House Check is a business information tool and is not directed at children under 13. We do not knowingly collect information from children.
We will update this page if our practices change and show the new date at the top. Significant changes will also be announced in the app.
