Privacy & Cookies policy
What TPO Checker collects, why, the third parties involved, and the choices you have.
Last updated: 5 November 2026
TPO Checker (“the site”) lets you check whether Tree Preservation Order (TPO) records appear near a UK postcode, free of charge, and offers an optional paid Protected Tree & Planning Report. This policy explains how we handle information when you use either.
If you have any questions or want to exercise your data rights, contact us at hello@tpochecker.co.uk.
Searches you run
When you check a postcode we record the search so we can understand how the site is used and keep it working. This includes the postcode you entered, the result (e.g. how many records were found and how close), your approximate location/area, your IP address, your browser and device (user-agent), the page that referred you, an anonymous visitor ID, and the date and time. We do not ask you to log in and we do not knowingly collect special-category data.
Enquiries you send (“request a quote”)
If you choose to submit the enquiry form, we collect the details you provide — your name, email, phone number (optional), postcode, the type of work, and your message — together with the same request context above (IP, browser, time). This is so the enquiry can be read and followed up. A copy is also saved in your own browser so you can see what you sent.
Emailing yourself a result
If you ask us to email you a check result, we store your email address, the postcode and what the check found, with the same request context above, and send that one email. If you also tick the box to hear what to check before tree work, we send up to three more emails over the following week about your result and the paid report. They stop early if you buy a report or unsubscribe, and every one has an unsubscribe link. Unsubscribing stops all marketing email from us.
Report purchases
If you buy the paid report, payment is handled entirely by Stripe — we never see your card details. We store your email address, the postcode and property address the report covers, the order reference, and the order's status so we can deliver the report, re-send it if needed, and process refunds. The finished PDF is stored so your download link keeps working.
At checkout you can choose to receive occasional emails about TPO Checker. We only send these if you said yes, and every one has an unsubscribe link. If you buy using a business email address, your report email and confirmation page may also mention TPO Checker Pro, our plan for firms.
We use a small number of first-party cookies and browser storage. When you first visit, a cookie notice lets you accept or decline optional analytics. Analytics cookies are only set if you accept; you can change your mind by clearing the site's storage in your browser.

To work, the site sends some information to the services below. The first two are public data sources we query on your behalf; the others help us host and operate the site.
| Service | Used for | What it receives |
|---|---|---|
| Postcodes.io | Turning your postcode into map coordinates and an area name. | The postcode you entered. |
| planning.data.gov.uk | The national Tree Preservation Order dataset we search. | The coordinates derived from your postcode. |
| OpenStreetMap | Map tiles shown on the results map. | Your IP address and the map area being viewed (standard for any web map). |
| Google Analytics (Google) | Optional usage analytics — only if you accept cookies. | Anonymised usage data (pages viewed, approximate region). |
| Meta Pixel (Meta) | Measuring and improving our Facebook and Instagram adverts — only if you accept cookies. | Pages viewed, browser and device details, and your IP address. |
| Google Ads (Google) | Measuring whether our adverts lead to Pro subscriptions. No advertising cookies are set. | If you arrived from one of our Google adverts and then start a Pro trial: the ad's click ID, the date you started and the amount of your first payment. Never your name, email or card details. |
| PostHog | Optional usage analytics and error monitoring — only if you accept cookies. PostHog processes this data in the United States under UK-approved safeguards. | Usage data (pages viewed, clicks, searches run) and technical error details. |
| Stripe | Payment processing for the paid report. Card details go directly to Stripe and never touch our servers. | Your email, payment details, and the property address/postcode named on the order. |
| Resend | Sends the report delivery email after a purchase, and result emails you ask for. | Your email address, the report PDF, and the postcode and result in a result email. |

| Vercel | Hosting and serving the website. | Standard request data (including IP) needed to deliver pages. |
We do not sell your personal data, and we do not use it for third-party advertising.
Under UK data protection law, we rely on legitimate interests to log searches and keep the site secure and working, on your consent for optional analytics cookies, on taking steps at your request when you submit an enquiry or ask us to email you a result, and on performance of a contract when you buy a report (we need your email and the property details to deliver it, and we keep order records to meet our accounting obligations). Marketing emails rely on your consent, which you can withdraw at any time.
We keep search logs and enquiries only as long as needed for these purposes and then delete or anonymise them. You can ask us to delete your enquiry at any time.
You have the right to access, correct or delete your personal data, to object to or restrict its processing, and to withdraw consent for analytics at any time. To make a request, email hello@tpochecker.co.uk.
If you are in the UK and are unhappy with how we handle your data, you can also complain to the Information Commissioner's Office (ICO).
We may update this policy as the site evolves. Material changes will be reflected by the “last updated” date at the top of this page. See also our About TPOs page for the data accuracy disclaimer.
