This Cookie Policy explains how Greenfinch AI, Inc. ("Greenfinch," "we," "us," or "our") uses cookies, local storage, and similar browser-storage technologies on our website and platform at greenfinch.ai and app.greenfinch.ai (the "Service"). It supplements our Privacy Policy, which describes our broader data practices, including the product usage telemetry summarized below.
Greenfinch does not use third-party advertising cookies, cross-site behavioral-advertising trackers, or third-party analytics cookies (such as Google Analytics) on the Service. The categories and principal first-party keys below describe the browser storage the Service currently uses: essential authentication and security cookies, local storage used for interface state, and session storage used for per-tab workflow continuity. We keep this description accurate as the Service changes; if a future feature adds a new cookie or storage category, we will update this Policy before it goes live.
These cookies are strictly necessary for authentication or a security-critical Service workflow. Clerk sets the authentication cookies; Greenfinch sets the short-lived onboarding cookie. Disabling them prevents sign-in or the related secured workflow from functioning correctly.
| Cookie | Purpose | Duration |
|---|---|---|
| `__session` | Manages your authenticated session | Session |
| `__clerk_db_jwt` | Secure authentication token used to validate your session | Session |
| `__client_uat` | Records when your Clerk client was last updated, so a signed-out browser is recognized correctly | 1 year |
| `gf_onboarding_verified` | Short-lived, signed proof that the current user completed the onboarding verification step | 1 hour |
Depending on the authentication flow and Clerk configuration, Clerk may also set short-lived session-refresh or redirect-handshake cookies such as `__refresh`, `__clerk_handshake`, `__clerk_redirect_count`, and `__clerk_handshake_nonce`.
We do not use analytics or advertising cookies. The local- and session-storage items described below are not sent to our servers on every request; the Service reads them in the browser while you use the relevant signed-in feature.
Local storage lets your browser remember choices you make in the Service between visits. Unlike a cookie, local storage is not transmitted with every request — it is read only by the page itself. The Service currently uses local storage for:
| Key | Purpose |
|---|---|
| `theme` | Remembers your light/dark mode preference (set by the interface theme control) |
| `greenfinch_map_label_metric` | Remembers your preferred map label metric |
| `greenfinch_map_legend_open` | Remembers whether the map legend panel is expanded |
| `propdash-visible-columns` (and a per-user variant) | Remembers which property-table columns you have chosen to show |
| `pipeline_swipe_hint_seen` | Remembers that you have already seen the pipeline swipe-gesture hint, so it is not shown again |
| `greenfinch_enrichment_queue` | Tracks in-progress enrichment requests you started, so their status survives a page reload |
| `greenfinch_active_filters` | Remembers your active search/map filters |
| `greenfinch_contacts_view` | Remembers your preferred contacts list view |
| `greenfinch_organizations_view` | Remembers your preferred organizations list view |
| `property_saved_searches` (per-user variant) | Stores your saved searches locally for quick access |
Most account-scoped values are cleared automatically when you sign out, so a different person signing in on the same browser does not inherit them. Your `theme` (light/dark) choice and the map legend setting (`greenfinch_map_legend_open`) may persist across sign-out. Property-tooltip data is kept only in memory while the active map is open; it is not written to local or session storage.
Session storage lasts only for the current browser tab. The Service uses `greenfinch_enrichment_session` (including a per-user scoped variant) as a random per-tab identifier that distinguishes a continuing tab session from a newly opened tab. It is cleared when you sign out and when the browser tab closes.
When enabled, Greenfinch records first-party, cookie-free usage telemetry (feature-use and performance events) to help us improve the Service, as described in our Privacy Policy. This telemetry does not use a cookie or a persistent browser identifier — it is keyed to a temporary, in-memory per-tab session identifier that is discarded when the tab closes, and to your signed-in account identifier when you are logged in. Telemetry is off by default and is only active when we have enabled it. See our Privacy Policy for the full description.
We use an error-monitoring service to help us detect and fix bugs. It does not set tracking cookies or perform session-replay recording. It may associate an error report with your signed-in account identifier and limited request context so we can diagnose the issue.
When you complete a purchase, Stripe's hosted checkout and billing-portal pages may set their own cookies on stripe.com domains to process your payment securely. Those cookies are not set by Greenfinch and are governed by Stripe's privacy policy, not this one.
Essential authentication cookies cannot be disabled without losing the ability to sign in. If you disable cookies in your browser, you will not be able to use the authenticated parts of the Service.
Most browsers let you view, manage, and delete cookies and local storage through their settings:
Clearing local storage for greenfinch.ai or app.greenfinch.ai will reset your saved interface preferences to their defaults; it does not affect your account, Customer Data, or credit balance, which are stored on our servers.
We may update this Cookie Policy to reflect changes in the technology, cookies, or local storage the Service actually uses. We will post updates here and update the "Last updated" date above. If a future change would add a new tracking technology not described here, we will update this Policy before that change takes effect.
