Public research preview · October 17, 2026

This public research preview includes an optional future-newsletter signup. It does not include advertising scripts or payment forms. Optional Google Analytics stays off unless you accept it; the separate first-party aggregate counter is described below.

The calculator and state filter run in your browser. This site’s application code does not send those inputs to a server or save them in browser storage.

The hosting platform may process request, security, authentication, and usage information under its own terms. This notice does not describe every hosting-platform practice.

Comparison links

Your selected comparison states appear in the page URL and may be recorded in your browser history. Opening or sharing that URL includes those selections in the request to the hosting platform. The application does not add a separate analytics event or store the selections in browser storage.

Planner context

Following a state guide’s planner link puts that state in the calculator URL. That context may appear in browser history and hosting request logs. Vehicle descriptions, glass and film percentages, and your chosen target are used locally by the application; the planner does not add them to the URL or save them in browser storage.

Factory glass lookup

Year, make and model entries stay in your browser. The site searches a local reference catalogue; it does not send your vehicle query to NHTSA or an automaker. No VIN, registration number or photograph is requested. The catalog lookup does not change calculator inputs or save your entries.

Newsletter signups

You can choose to join the future Window Tint Laws newsletter. Email delivery and confirmation emails have not started. Joining does not create an account, verify ownership of an email address, or promise real-time law alerts.

When you submit the form, the application sends your email address and your explicit consent to the site’s private database on its hosting platform. The record includes the signup time, consent wording version, site identifier, unconfirmed status, and a protected digest of a private removal token. There is no public subscriber list. The application does not save your email in browser storage. This signup flow does not send the list to an email-marketing provider or activate advertising or third-party analytics.

We retain the signup record, including after withdrawal, to preserve your choice and prevent an ordinary repeated signup from adding you back. There is currently no automatic deletion schedule. Save that link and keep it private: anyone with it can remove the associated signup. Using a matching link marks the record withdrawn and records the withdrawal time; it does not erase the retained email and consent record. Repeated signups do not change an existing record or issue a replacement removal link. You can send a private question through Contact us. An alternative way to recover a lost removal link is not available yet.

For abuse prevention, the application stores request counters and a salted hash derived from the request’s network address and site identifier; it does not store the raw network address in the signup database. Source-specific counters expire after at most two hours, site-wide counters after at most 25 hours, and daily salts after at most 48 hours. Cleanup happens in bounded batches during later requests, so expired records may remain longer when the site has little traffic. The hosting platform may separately process request and security information under its own terms.

Newsletter delivery has not started. The current signup stores your request as described above. Information about email delivery, confirmation, unsubscribing and any added providers or retention practices is not yet available; this notice must explain those details before delivery begins.

Information still missing from this notice

This is an interim notice for the public research preview. The site operator’s full identification, hosting-provider details and applicable privacy-rights procedures are not yet set out in this interim notice. You can send a private website question through our contact form. Additional provider or data-use information, and any required consent, must be in place before advertising or additional analytics is activated.

Basic page counts

We use a small built-in counter to understand which public pages are read. It keeps only the UTC calendar day, the public page path and a total view count in this site's private database. The counter does not store IP addresses, browser details, referral pages, full URLs, search or filter values, form entries, visitor identifiers or individual viewing histories.

The counter uses no cookies or browser storage and sends no analytics to a separate analytics provider. Preview pages and marked testing visits are excluded. It respects supported Do Not Track and Global Privacy Control signals. The totals are approximate pageviews, not a count of unique people. Aggregate counts remain available to the site owner until removed; no automatic deletion schedule is configured.

Our hosting service still processes the network requests needed to deliver and protect the site. Its technical request records are separate from these aggregate page counts.
