LandCheck is a research aid published by LandCheck LLC, a Virginia limited liability company. By using it you agree to these terms.
What LandCheck is, and is not
LandCheck displays data fetched live from public sources: county and state GIS servers, FEMA, USGS, USDA, the US Census Bureau, the FCC (a backup for the county name at a point), USFWS, NOAA, OpenStreetMap contributors and the county/city services listed in the app under Is my county covered? LandCheck does not create, own or warrant that data. This product uses the Census Bureau Data API but is not endorsed or certified by the Census Bureau; it uses FEMA's National Flood Hazard Layer but is not endorsed by FEMA.
Basemaps, imagery and address-search results are provided by Esri through the ArcGIS Location Platform. By using the map you agree to use that imagery and those results only within LandCheck (no copying, scraping, bulk downloading, storing or caching beyond what your browser does automatically) and to keep the "Powered by Esri" credit visible; static copies in a PDF report are allowed. The full list of licences and credits is on the notices page.
When you choose the Google Map or Google Satellite basemap, LandCheck includes Google Maps features and content: map tiles and, as you type in the search box, place suggestions from Google Maps Platform. Your use of them is subject to the then-current Google Maps/Google Earth Additional Terms of Service and the Google Privacy Policy. Google's logo, attribution and terms link stay on the map; Google content is shown as served and is not copied, stored or cached, and the PDF report never includes it.
Parcel boundaries are county GIS renderings, not surveys. Flood, soil, elevation, HOA and every other readout can be out of date, incomplete or wrong. Nothing here is a substitute for a licensed surveyor, a title search, a lender's appraisal, or legal advice. Do not make a purchase decision on LandCheck alone. Flood-exposure and buildable-land figures are estimates read off public map layers at coarse resolution — not floodplain determinations, wetland delineations or buildability opinions.
Data providers change or switch off their services without notice. Features can stop working and coverage can shrink; LandCheck is provided as is, without warranty of any kind, and to the fullest extent permitted by law LandCheck LLC is not liable for any loss arising from its use.
Acceptable use
Use LandCheck for your own research. Do not scrape it, hammer the underlying public services through it, or use owner information it displays for unsolicited commercial contact — several states prohibit that use of assessor data.
You may not resell, re-host or white-label LandCheck without written permission.
Changes
These terms can change; the date above moves when they do. Continued use after a change means you accept it.
Privacy
No account, no advertising trackers, no third-party cookies. LandCheck runs in your browser. The only cookies are set by landcheck.io when you activate Pro (with the key or with an emailed sign-in code): an HttpOnly random token sent only to landcheck.io's own /api/ address, which keeps Pro signed in on that browser if its local storage is cleared, and a one-character marker that only tells the app a session exists. Neither holds personal data, and both are removed by “Remove Pro from this browser”. While an emailed sign-in code is pending, a third ten-minute cookie ties that code to the browser that asked for it. Your saved places, settings, notes and license key live in your browser's local storage and are never uploaded unless you turn on Pro sync.
What leaves your browser
Map clicks and searches are sent directly to the public data providers to fetch results (for example a coordinate to FEMA or USGS, or to the US Census Bureau to name the county and city it is in (to the FCC for the county when the Census Bureau does not answer); whatever you type in the search box — an address, a city, a ZIP — to Esri's geocoder under the same key as the basemap and, when it finds nothing or for the county or town a land-listing link names, to OpenStreetMap's Nominatim; a map area to a county GIS server). Those services see your IP address and may log the request under their own policies. LandCheck itself does not receive these requests.
Google basemaps. If you switch to Google Map or Google Satellite, your browser requests map tiles from Google and, as you type in the search box, suggestions from Google Places; Google sees your IP address, the map area and the typed text under its own privacy policy. Nothing goes to Google while an Esri or USGS basemap is showing. LandCheck keeps none of it: the recent-searches list stores what you typed, not what Google returned.
Page views are counted with Cloudflare Web Analytics, which uses no cookies and no fingerprinting and reports only aggregate numbers.
Visit-to-purchase counts. To learn which pages and which sites bring visitors who go on to subscribe, the app sends landcheck.io a short note at five steps: arriving from another site (or typing the address), opening the first parcel, opening the Pro screen, viewing the pricing page, and clicking Subscribe. A note holds only the step, a one-word label for where the visit came from, picked from a fixed list (for example “google”, “reddit”, “direct”, or “campaign” for any link tag not on the list), the landing page on arrival and the plan on Subscribe. It is sent with no cookie, and nothing that identifies you or your browser is kept with it: no ID, no IP address, no location. Each note is stored on its own with the time it arrived, for about three months, and LandCheck reads only totals from them. The label is remembered for this browser tab only (in its session storage) and is added to the Subscribe links, so the store keeps it on your order and sends it back to LandCheck's server when the order is placed. That message from the store also carries the order details, including your name and email; the server reads only the label, the plan and whether it was a test order, and keeps nothing else from it.
Newsletter sign-up. If you subscribe to the monthly letter, the address you type and your optional choices (a state, notes on new counties) pass through LandCheck's server to Brevo, the email service that sends the letter for LandCheck. The server keeps no copy of the address. To stop repeated sign-ups it keeps short-lived counters named by a keyed one-way hash: of the address for a day, and of your IP address for fifteen minutes. Brevo emails you a confirmation link and adds you to the list only after you click it; normally no more than two confirmation emails go to one address a day. Brevo holds the list on LandCheck's behalf, and LandCheck decides what it is used for and how long it is kept. Brevo counts opens and clicks of each issue only as anonymous totals, not tied to a reader. Every issue has an unsubscribe link, and an email to help@landcheck.io has an address deleted.
Hosting is Cloudflare; standard server logs (IP address, user agent, request path) are retained briefly for security and operations.
If you buy Pro
Purchases are handled by our merchant of record (Lemon Squeezy), which collects your payment and billing details under its own privacy policy and gives you a license key. LandCheck LLC never sees your card number. The charge appears on your statement as LEMSQZY* followed by the store name.
Activating a key sends the key to LandCheck's server, which checks it with the store and stores a hashed copy so later checks are fast. If you enable sync, your saved places (labels, notes, coordinates, parcel fields you saved) are stored under that hashed key on Cloudflare's key-value storage so your other devices can fetch them. To keep a browser signed in, an encrypted copy of the key is stored behind a cookie for up to 400 days, and removed when you remove Pro from that browser. Nothing else is stored, and you can wipe your saved places at any time from the Pro screen or by email.
If you subscribe, we email you before a renewal: 30 days before a yearly renewal, and once a year on a monthly plan. LandCheck's server reads your address and price from the store when a reminder is due and does not keep them; it keeps only a hash of the subscription and the renewal date for 60 days, so the reminder is not sent twice. Our mail provider, Brevo, delivers it, records its delivery and when it is opened, and keeps those logs under its own privacy policy.
If you ask the Pro screen for a sign-in code by email instead of pasting the key, the address you type is sent to LandCheck's server, which asks the store for the license bought with it and emails you an eight-digit code through our mail provider, Brevo. LandCheck's server does not store the address: it keeps a keyed hash of it for up to 24 hours — as the name of the ten-minute code record and as request counters (three codes per fifteen minutes, eight per day) so one address cannot be flooded with codes — whether or not a subscription is found, and a keyed hash of your network address for fifteen minutes to limit requests. Brevo sees your address and the message, records its delivery and when it is opened, and keeps those logs under its own privacy policy. The code works once, only from the browser that asked for it, and signing in this way sets the same cookies as activating a key.
Your rights
Clearing your browser's site data removes everything LandCheck keeps locally. For sync data or any privacy request, email the address below and it will be deleted within 30 days.
LandCheck Pro
Pro is a subscription ($100 a year or $15 a month) that renews automatically at the end of each paid period until you cancel, and unlocks the features listed on the Pricing page and the Pro screen in the app for the subscriber's personal use on the browsers they activate. It is a license, not a transfer of ownership.
You can cancel at any time from the link in your receipt email; Pro stays on until the end of the period you paid for and does not renew after that. When a subscription lapses, the key stops validating and the app returns to the free plan; saved places stay in your browser.
Everything data-related stays free for everyone. Pro features depend on the same public services and can be affected when those change.
A key can be deactivated on one browser and used on another. Sharing a key publicly voids it.
Exports are for your own research. You may not use owner names or addresses from reports or CSV files for commercial solicitation, and you may not resell or republish the data they contain. South Carolina law makes solicitation use of public records an offense; the notice printed on South Carolina exports is part of the record.
Refunds
Payments are not refunded, except where the law requires it. We may refund at our discretion, for example when a Pro feature stopped working because a data provider changed: email help@landcheck.io with the address you subscribed with. Cancelling stops the next renewal; Pro stays on until the end of the period you paid for.
Refunds are issued by our merchant of record, Lemon Squeezy, to the original payment method and typically appear within 5–10 business days. A refund ends Pro: the license key stops working and the subscription does not renew.
Disclosures
Referral links. LandCheck may show links to third-party services near a parcel (surveyors, septic, well, solar, lenders and similar). Some of those are paid referral links, and they will be marked as such next to the link. Referral links never change what you pay, and they are never a recommendation of a specific company.
No financial or legal advice. LandCheck is not a licensed appraiser, surveyor, attorney, broker or financial adviser.
Mail to that address is received by Cloudflare Email Routing on the landcheck.io domain and forwarded to a mailbox the company uses at a third-party mail provider, which handles it under its own privacy policy; Cloudflare handles the message envelope only to deliver it. Your message is kept as long as it takes to answer it, is never added to a list, and is never shared. Ask in the same thread and it is deleted.
