Your criteria and your email address. That's all we hold.

Siere Signal stores the search criteria you set, your email address, and — if you subscribe — your billing state at Stripe. We never sell or share your data, and no listing pays to reach you.

Delete your account any time from your account page — it's a button, not a support ticket. Within 30 days your searches, preferences, and address are removed from our systems; invoices remain with Stripe as required by tax law.

Every email we send carries a one-click unsubscribe. Bounced or complaining addresses are suppressed permanently.

Full policy text pending legal review — this page states the operating practice it will formalize.
