Privacy
Updated October 6, 2026. Terreflow is operated by Lyncius LLC. For privacy questions or account-deletion requests, contact [email protected].
Browser identity and purchased access
Terreflow uses a random browser identifier, stored in your browser, to track free-location usage and purchased access. Purchase ownership is not established by your IP address or a device fingerprint. Security and abuse-prevention checks may use network and browser signals. Our Cloudflare database stores browser identifiers, location-access records, purchase references, and access-expiry times.
Optional Google sign-in after purchase
You can purchase and use a pass without Google. If you explicitly choose Save this pass with Google after a confirmed purchase, Google provides a verified account identifier and email address. Terreflow stores that identifier, email, account timestamps, and links to your purchasing browser identifiers in its Cloudflare D1 database. This lets you restore a saved pass in another browser.
Terreflow requests only basic identity information. We do not receive your Google password or request access to Gmail, Drive, contacts, or calendars. Google credentials are verified on the server; the identity database does not store Google ID tokens or Google access tokens. A signed, HttpOnly cookie maintains your Terreflow login.
Google identity information is used for account identification, purchase linking, and recovery, not as an input to AI land analysis. Sign-in does not extend a paid pass. The seven-day access period begins when Terreflow confirms payment and first records the pass activation; access ends at its recorded expiry. Identity records are not automatically deleted when access expires. You may contact support to request deletion. Purchase and security records may need to be retained separately from account identity.
Payments
Stripe handles checkout and card processing. Terreflow receives payment status and transaction references needed to grant and support access; the website does not collect card numbers directly. Signing in with Google does not create a subscription or authorize another charge.
Location analysis, AI, and infrastructure
When you search or analyze a location, addresses, coordinates, analysis inputs, and any AI-chat text you submit may be sent to the providers needed for geocoding, maps, terrain and hazard data, or AI responses. Avoid entering sensitive personal information in chat or location inputs. Cloudflare hosts Terreflow and provides database, security, and website-analytics services. Google and Stripe handle their respective sign-in and payment services under their own privacy policies.
Your choices
Google linking is optional. Skipping it keeps access in the purchasing browser, but clearing site data or switching browsers will not automatically recover an unlinked pass. To restore linked access, use the same Google account with which you saved the pass. For help with an unlinked purchase, contact support; matching an email address alone is not proof of purchase ownership.
