Cookie Policy

Clear details on how Rein uses minimal browser storage without behavioral advertising pixels, third-party analytics cookies, or cross-site tracking.

1. What Are Cookies & Local Storage?

Cookies are small text files placed on your device by websites or infrastructure providers to support site functionality or transmit state across HTTP requests.

Instead of setting first-party tracking cookies from our application, rein.design uses browser Local Storage for lightweight interface state. Values saved in Local Storage remain inside your browser and are not transmitted as cookie headers or used to profile visitors across websites.

Minimal Footprint: Rein Design Studio does not set first-party application HTTP cookies, analytics cookies, advertising pixels, or behavioral fingerprinting scripts on our website.

2. Why We Use Local Storage

Client-side browser storage on this website is limited strictly to interface stability:

Consistent Hydration & UI State: Applying the default theme token and light-mode appearance attribute before hydration so pages render smoothly without layout or color flashing.
Spam Protection on Contact Requests: Our contact form relies on stateless form fields and a hidden honeypot field rather than placing client-side tracking cookies.

3. Categories of Storage Used

Any client-side or infrastructure storage involved when visiting this site falls into two narrow categories:

Essential Interface State

Browser Local Storage entries initialized on page load to ensure consistent visual theme and appearance attributes before React hydrates.

Infrastructure & Edge Security

Strictly necessary technical cookies or headers that our hosting provider may set at the network edge for routing, DDoS protection, or form abuse prevention.

4. Browser Storage Inventory

The table below lists the exact browser storage keys initialized by our website code:

Key / Identifier	Mechanism	Purpose	Lifespan
rein_active_theme	Local Storage	Stores the active design system theme identifier (defaulting to `zinc`) during hydration.	Persistent (until cleared)
rein_color_mode	Local Storage	Maintains the light-mode appearance attribute prior to hydration.	Persistent (until cleared)
First-party HTTP cookies	None set by app	Rein application code does not read or set any HTTP cookies.	N/A

5. Third-Party Assets & External Links

Primary typefaces (Onest and Inter) are bundled and served directly with the application rather than requested from external font tracking scripts. Certain showcase assets or imagery may be delivered via image CDNs such as Unsplash or CloudFront.

We do not embed advertising SDKs, remarketing tags, or social media tracking pixels (such as Meta Pixel or TikTok Pixel) anywhere on our site. If you click an external link (such as LinkedIn, X, or GitHub), that third-party service governs its own cookies and privacy practices.

6. Managing Your Storage Preferences

You have full control over cookies and Local Storage entries in your browser:

Browser Settings:You can configure Safari, Chrome, Firefox, or Edge to block or alert you about cookies at any time. Blocking third-party cookies will not affect core browsing on rein.design.

Clearing Local Storage:You can inspect or remove rein_* Local Storage entries anytime through your browser's site data or privacy controls.

7. Policy Updates & Inquiries

We may update this Cookie Policy if we introduce new interactive capabilities, hosting integrations, or analytics tools. For further details on how we handle personal data, see our Privacy Policy. Questions may be directed to legal@rein.design or hello@rein.design.
