Privacy Notice
Last updated: 26 July 2026
This page describes what martianestate.com (the "Site") does — and, mostly, does not — do with your data. We've kept data collection minimal on purpose, which keeps this notice short.
Summary
The Site itself sets no advertising cookies, no analytics cookies, and no third-party tracking cookies. It does not use fingerprinting. It does not sell or share personal information, as those terms are defined under the California Consumer Privacy Act (CCPA/CPRA). Browsing this Site does not require an account, and no purchase is ever completed on this Site — every "Reserve This Parcel" button takes you to Square Online, where the transaction actually happens.
What we collect on this Site
Nothing, if you're only browsing. The parcel catalog, plats of survey, region illustrations, and pricing are static files served to your browser; no server-side logging of personal identifiers is performed beyond standard, short-retention web server access logs (IP address, timestamp, requested page) used solely for security and abuse prevention, and not linked to any profile. We never see your name, shipping address, or payment details, because we never collect them — Square does.
Local storage, not cookies
The Site uses one piece of local browser storage: a flag remembering that you've dismissed the "no tracking cookies" notice bar, so it doesn't reappear on every page. This is stored only in your browser (localStorage), is never transmitted to us or anyone else, contains no personal information, and is strictly necessary for that one interface behavior. No consent banner is required for this under GDPR or the ePrivacy Directive because it is not used for tracking, profiling, or analytics.
Checkout happens on Square Online, not here
Clicking "Reserve This Parcel" redirects your browser to a product page hosted on Square Online, operated by Block, Inc. (Square). That page — not this Site — is where you enter your name, shipping address, and payment details, and where the purchase is completed. Square is a separate business and, for that information, a separate data controller: it is governed by Square's own privacy notice for buyers, available at squareup.com/us/en/legal/general/privacy-no-account (Square's general privacy notice is at squareup.com/us/en/legal/general/privacy), which we encourage you to read before checking out. We do not receive a copy of what you enter on Square's site beyond order confirmations we need to fulfill and ship your certificate.
Two small technical notes on the handoff itself: the link you click carries a plain-text parcel identifier (e.g. "OMF-014") so we and Square both know which parcel you're reserving, and, like any outbound link, your browser may send Square the address of the page you clicked from as an HTTP referrer. Neither of these identifies you personally on their own, and neither is used by this Site for tracking.
Because Square is a United States company, if you are located in the EU, UK, or elsewhere outside the US, your information will be transferred to and processed in the US once you reach Square's checkout. Square maintains its own data transfer safeguards (including Standard Contractual Clauses) for these transfers; details are in Square's privacy notice linked above.
If you contact us directly
If you email hello@martianestate.com, we retain that correspondence only as long as needed to respond and to keep a reasonable business record, and we don't use it for marketing without separate, affirmative consent.
Your rights (GDPR & CCPA/CPRA)
Because we don't build profiles or sell/share personal information, most access, deletion, correction, portability, and opt-out requests will simply confirm we hold nothing about you tied to your browsing. If you've emailed us directly, you can ask us to access, correct, or delete that correspondence at any time by writing to hello@martianestate.com. For any request about the order information you gave Square directly — name, shipping address, payment details — please contact Square using the process in their privacy notice, since that information was never in our hands. EU/UK residents may also lodge a complaint with their local data protection authority; California residents may contact the California Privacy Protection Agency. We do not discriminate against anyone for exercising these rights.
Children's privacy
This Site is not directed to children under 16 and we do not knowingly collect personal information from them.
Changes to this notice
