This notice explains what information I use, why, and your choices. No account is needed. Website analytics cookies are optional.

Who is responsible

Outstandly Ventures Ltd is the data controller for Inspector Walls. Our registered address is above and our contact email is below.

Information I use

For property checks, I use the address or listing you provide and relevant property details: location, price or rent, size, type, tenure, energy rating, bills and estate-agent details. Providing these is optional, but I need enough information to run the check. The extension sends selected property details, not the listing’s full text or photographs. Rent and bill figures you edit stay in your browser. On the website, what you type in the address search goes to UK address-lookup services so they can suggest matching homes.

I also use public property, planning and aircraft records, listings and mapping data. These can include home addresses and aircraft registrations. Public planning descriptions may be summarised by software. I do not make automated decisions about people with legal or similarly significant effects.

Connection information, including your IP address, browser and requests, is used to deliver and protect the service. Messages and optional goodbye notes include what you write and any contact details you give.

Stripe takes payments for full reports and donations. It receives your card or wallet details and your email, and for a report the home’s address, and it sends your receipt. I receive confirmation of the payment, never your card details; for a donation, Stripe also passes on your name and email. For a report I keep a one-way code made from your email, your card’s last four digits and the home, so I can find your payment if you lose your key. It can’t be turned back into your email.

Stripe’s payment form loads from Stripe when a report offers you the full version. It sets two cookies, __stripe_mid and __stripe_sid, and collects device signals to prevent fraud. They are needed to take payments safely, so the analytics choice does not cover them.

Analytics and error reporting

Basic visit counts

I count visits without analytics cookies.

I use optional website analytics to see what works and what needs fixing. PostHog receives this information only after you choose Allow. A random browser identifier links visits and actions. Events include pages, clicks, browser and device information, campaign tags and approximate location. On Doomsday, they also include search outcomes, postcode districts and displayed results. On reports, they also include whether the price was shown, checkout was opened and the report was bought. Typed search and form contents do not go to analytics. Referring page URLs retain their public path, including a property listing path; query strings and fragments are removed. AI model training on this data is disabled.

You can turn optional website analytics off at any time by choosing No thanks. This also removes its browser storage. Basic website statistics are separate and use no analytics cookies. They count visits, checks, report purchases, entry and exit pages, time spent on pages and how far people scroll, with campaign tags and public referring-page paths. When a browser shows it, they also note which app opened the link. Query strings and fragments are removed from referring URLs. PostHog receives grouped totals, with no visitor identifier, IP address or typed search and form contents. Public page paths are retained. Temporary page tokens and daily counting hashes stay in server memory only.

Choose Leave me out under Basic visit counts to stop basic counting in this browser. Basic counts keep no identifier, so Do Not Track and Global Privacy Control don’t switch them off. The privacy page sends no analytics or browser fault reports.

I also count inspections by council, the first part of the postcode and property website. These totals do not identify who asked or include a full postcode, address, listing or other property details.

Optional extension statistics include installs, inspections, feature use, repeat use, browser version and approximate country and city. These go to PostHog. A daily identifier can link events within a day. If your extension supports it, the setting below stops these reports and automatic extension fault reports. Requested property lookups and service-security checks continue. Older “Count me in” controls stop only daily-use and pending installation reports.

When you remove the extension with usage statistics on, Chrome opens a goodbye page and the visit is counted. Leaving a note or email address is optional.

Website fault reports are separate from the analytics choice. They go to Sentry and contain error and technical details, which may include the affected page or listing path. URL query strings and fragments are removed. Changing a setting stops future optional reports; it does not erase records already received.

Why I use this information

Consent covers optional website analytics and its cookies. You can withdraw it at any time using No thanks. I rely on our contract with you to take a payment and open the report you bought. I rely on legitimate interests to run property checks, use public records, answer messages, understand aggregate use and keep the service secure. Required accounting records are kept to meet legal obligations.

Who receives information

Property checks use UK address-lookup and property-data services, official public registers, mapping and place-search services, and AI service providers. They receive the property details or public planning text needed for the check. Weather services receive only a coarse location for the footer.

Hosting and network-security providers process connection information. Services contacted by your browser also receive your IP address and browser details. Analytics, fault-reporting and payment providers are described above.

Where information is processed

Some providers process information outside the UK, including in the EU and United States. EU transfers are covered by UK adequacy regulations. Other restricted transfers use the UK International Data Transfer Agreement or the UK Addendum to standard contractual clauses, or the UK extension to the EU–US Data Privacy Framework where the provider is certified. Contact us for a copy of the applicable safeguards.

How long information is kept

  • Website choices and analytics cookies: up to 180 days; cookie expiry renews when used. Analytics also use session storage. Other browser preferences stay until cleared.
  • Stripe’s fraud-prevention cookies: up to one year (__stripe_mid) and 30 minutes (__stripe_sid). The key to each home you pay for stays in your browser until you clear it.
  • Extension reports: one day. Settings and usage counts stay until changed, cleared or removed; switching statistics off clears the count. Temporary recovery data: two minutes. Pending installation reports: up to 31 days.
  • Property lookup responses: up to 59 days. Limited historical council-tax results and published aircraft archives are retained indefinitely. Planning descriptions: seven days; planning facts: while live and up to three years afterwards. Basic case references and outcomes may be kept longer to recognise closed applications.
  • Request logs: 30 days. Sentry fault reports: 90 days. PostHog events: up to seven years. Temporary basic-counting identifiers: up to one day. Preserved Plausible aggregate exports are kept indefinitely. Information sent to AI providers: up to 30 days.
  • Messages and goodbye notes, including any email you provide: until acted on, and afterwards where needed to follow up or handle legal claims. Payment records: as required by accounting and tax law.

The extension keeps settings and reports on your device. Copied report links can contain the report’s property information.

You can object at any time to uses based on legitimate interests. Use the choices above for basic counts and the control below for this browser’s extension, or contact us.
