When you create an account, we store your email address and display name. If you subscribe to the weekly digest, we store your email and notification preferences. When you use the passport, we store which events you stamped and marked attended; when you file a field note, we store its rating, text, and the visibility you chose. Before you have an account, stamps you collect are kept only in your own browser's local storage and never reach our servers until you sign up. We do not collect payment information, precise location data, or any sensitive personal information.
Your email is used for account authentication, the weekly digest (only if you opt in), and short post-event check-ins asking how an event you stamped was (each has a one-click opt-out). Your activity on the site, such as the events you view, stamp, and rate, is used to rank and recommend events and to build aggregate figures like an event's average rating. We do not sell, share, or rent your personal information to third parties.
A field note publishes under the visibility you choose. Named notes show your first name and last initial; anonymous notes show no identifying information publicly. Notes you mark as visible only to the Stamps DC team are never published: the team reads them to improve coverage and recommendations, and only the rating counts in aggregate figures, which never identify you. Text you submit is screened before publication, using automated checks and human review.
Your browser may contact the following third-party services when using Stamps DC:
These services may log your IP address as part of standard web infrastructure. We do not use advertising networks or cross-site tracking.
Email link tracking records that a link in a given digest issue was clicked, and which link. It is used to judge which stories are worth running, never to build a profile, and it is not shared with advertisers. It is part of how the digest itself is sent, so the way out of it is the one-click unsubscribe link in every issue, or a reply asking us to stop.
We use PostHog to understand how the site is used (which events people view, search for, and save) so we can improve it. Analytics requests are sent to our own domain and forwarded to PostHog's US cloud. PostHog stores a randomly generated identifier in your browser to connect your actions within and across visits; this identifier is pseudonymous and is only linked to your account after you sign in. Digest link clicks are recorded in PostHog too, identified by your account if you have one and otherwise by a one-way hash that cannot be turned back into your address. We never send your email address or name to PostHog, and we do not use session recording, autocapture, or advertising identifiers.
Every digest email contains a one-click unsubscribe link. You can also manage your notification preferences at any time from your preferences page.
We retain your account data as long as your account is active. A field note you remove is hidden from the site immediately; we keep an internal record for moderation and abuse prevention. You can request a copy of your data, or deletion of your account and associated data, by emailing privacy@stampsdc.com; we honor these requests regardless of where you live.
Stamps DC is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has created an account, contact us and we will delete it.
We use Supabase with row-level security policies to protect your data. If you discover a security issue, please report it to security@stampsdc.com or see our security disclosure policy.
