Privacy Policy

This policy explains what the NYS Steep-Slope & Wetlands Analyzer (lyncview.com, operated by LyncView) collects, why, and what your choices are. The short version: we collect as little as possible, we don't sell data, and analysis runs against public GIS services — the parcels you look up aren't tied to your identity.

What we collect

Without an account

• Search analytics. Each analysis run logs the parcel/area searched, threshold, result summary, success/failure, and duration — with no name, email, IP address, or account attached.
• Essential cookies (see the table below) for the export paywall.
• Web analytics. Vercel Analytics and Speed Insights collect aggregated, anonymized page metrics (no cross-site tracking cookies, no ad identifiers).
• Error reporting. If an error occurs, a technical report (stack trace, browser version) may be sent to Sentry to help us fix it.

With an account

• Email address and a password hash. Passwords are hashed with bcrypt — we cannot read them.
• Purchase state. Your plan and Stripe customer/subscription identifiers, so signing in restores paid access.

When you pay

• Payments are processed entirely by Stripe. Card numbers never touch our servers. Stripe's handling of your data is described in the Stripe Privacy Policy.

Cookies

We use only first-party, functional cookies — no advertising or cross-site tracking cookies, so no cookie consent banner is required:

• tie_ent — signed proof of a paid export pass or subscription.
• tie_free — signed count of free watermarked exports used.
• tie_sess — your signed account session (only when you sign in).
• tie_owner — site-administrator session (staff only).

All are httpOnly, secure, and readable only by our server. Clearing cookies signs you out; signing back in restores purchases saved to your account.

What we do with it

• Operate the service: verify purchases, meter free exports, send password-reset emails.
• Understand usage in aggregate (which counties get searched, error rates) to improve the product.
• We do not sell or rent personal information, and we don't use it for third-party advertising.

Who we share with

Only the processors needed to run the service: Vercel (hosting, anonymized analytics), Turso (database), Stripe (payments), Sentry (error reports), our SMTP provider (transactional email), and CloudConvert (only the CAD file you convert, transiently, when you export DWG). Analysis queries go to public government services (USGS, NYS ITS, NYS DEC) and contain parcel geometry — never your identity.

Retention and deletion

• Account data is kept while your account exists. Deleting your account (from the account page) removes your email, password hash, and purchase records immediately, and sets any active subscription to cancel at period end.
• Anonymous search analytics are kept for product statistics; they contain no personal data.
• Stripe retains billing records as required for tax and accounting law.

Your rights

Depending on where you live (e.g. GDPR, CCPA/CPRA), you may have rights to access, correct, delete, or export your personal information, and to non-discrimination for exercising them. Most of these are self-serve: your only stored personal data is your account email and purchase state, and account deletion is built in. For anything else — or to exercise rights by request — email support@lyncview.comand we'll respond within 30 days. We don't sell personal information, so there is nothing to opt out of under CCPA “Do Not Sell”.

Security

Everything is served over HTTPS with strict transport security. Passwords are bcrypt-hashed, sessions and entitlements are signed server-side cookies, payment pages run on Stripe, and databases are access-controlled. No system is perfectly secure; if we learn of a breach affecting your data we'll notify you as required by law.

Children

The service is a professional tool and not directed at children under 13; we don't knowingly collect their data.

Changes

Material changes to this policy will be posted here with a new “last updated” date.
