Privacy, plainly.
Effective November 12, 2026. HammerHigher is a game project operated by Sycamore Estate Services. You can play without giving us your name, email address, or payment details.
What the game remembers
An essential, secure browser cookie identifies a randomly named player. We store game rounds, choices, results, saved items, and timestamps so your score, daily attempt, and collection work. The leaderboard displays your automatically generated alias and score. Shared challenge links expose the score and game sequence, not an email address.
Your sound and automatic-advance choices and an unfinished game identifier are stored on your device. Clearing the cookie or site data starts a new anonymous player. If you request and complete an email confirmation, the proof link can reconnect another browser to the original profile.
Email is optional
If you request email confirmation, we store your email address, the email categories you explicitly request, any interests or location you choose to provide, and the time and version of your consent. “Join the list” requests weekly finds, game highlights and occasional auction recommendations. You can choose just one email category or save progress with no marketing; preferences remain separate. We do not sell your email, and choosing not to subscribe does not change the game.
We operate our own consent records, message queue, preferences, suppression list and SMTP delivery software. Email is held until a verified sender and mail server are configured. Requests made while delivery is held are disclosed as stored requests, not confirmed subscriptions. Marketing remains inactive until you confirm. We do not automatically add this audience to another business’s mailing list.
Service providers and analytics
The site runs on ChatGPT Sites and Cloudflare infrastructure. Necessary request information may be processed by those providers to host and secure the game. We keep first-party aggregate game counts, such as completed rounds, chosen categories, share intent and challenge arrivals, to improve the experience. We do not embed third-party advertising trackers. Auction photographs are served with the game, so your browser does not contact the auction house directly to display them.
Your choices
Open “Privacy” in the game menu or footer to withdraw email interest submitted from this browser. Email links use opaque random proof, without your address in the URL. Opening a confirmation or unsubscribe page alone changes nothing; email services may also use a one-click unsubscribe POST. To request access, correction, deletion, or other changes, contact the operator through the Sycamore Estate Services website and mention HammerHigher. We may need to verify that the email address is yours. Do not send identification documents.
Retention
Game and collection records are kept while the service runs or until a verified removal request is completed. Short-lived abuse limits use a daily-changing hash of a network address when supplied by the hosting platform; we do not store the raw address in the game database. Expired rate-limit records are pruned. Subscriber choices remain until you withdraw or request verified removal. Minimal hashed suppression records and consent history may remain to honor opt-outs and document permission. Confirmation links expire after 24 hours; preference links expire after 30 days. Proof tokens are hashed in the database. Undelivered messages contain an address and proof link in the private queue; accepted or suppressed message payloads are cleared. A private delivery journal records message IDs and outcomes to prevent duplicate sends. SMTP acceptance does not prove inbox delivery.
Children and money
The game does not require payment and offers no cash prizes, bidding, or purchases. Email subscriptions are intended for people aged 18 and older. Historical auction results are for entertainment and are not appraisals or investment advice.
