Cookie policy
Optional stays optional.
Arju stores your consent choice, and Vercel may set cookies or use similar technology to deliver, protect, measure or control access to the deployed website. This notice explains each purpose and the choices available to you.
LAST UPDATED · 11 AUGUST 2026
Current position
Arju and Vercel have separate roles
Arju stores one browser record containing your necessary, analytics and personalisation choices. Vercel hosts and delivers the website and may set its own cookies or similar browser records for deployment authentication, security challenges, preview tooling and other configured platform functions.
Some Vercel functions are strictly necessary for secure delivery or access. Other measurement or preference functions are treated according to their purpose and configuration. The consent control keeps Arju’s optional categories off until you choose them.

Technology register
| Technology | Provider | Purpose | Duration | Consent |
|---|---|---|---|---|
| arju-cookie-consent-v1 in browser local storage | Arju | Remember necessary, analytics and personalisation choices so the banner does not repeatedly ask | 180 days, unless you clear site data or the consent version changes | Strictly necessary to record and respect the privacy choice |
| Deployment authentication cookie, when protection is enabled | Vercel | Confirm that a visitor is allowed to open a protected preview or production deployment | Controlled by Vercel and scoped to the protected deployment URL | Strictly necessary when the requested deployment requires authentication |
| Firewall challenge session cookie or similar browser record, when a challenge is triggered | Vercel | Remember that the browser completed a security challenge so later requests can reach the site | Vercel documents a one-hour challenge session | Strictly necessary for security and abuse prevention when the challenge applies |
| Vercel Toolbar and feature-flag preference storage, on preview or explicitly enabled environments | Vercel | Support deployment comments, preview preferences, development tools and feature-flag overrides | Session-based or retained according to the selected Vercel tool and account preference | Necessary for a visitor who requests the tool; optional controls apply where a non-essential preference is offered |
| Vercel Web Analytics, when enabled | Vercel | Measure aggregated page views, referrers, device information and site usage | Vercel documents daily-reset visitor identification | Managed as analytics processing. The Analytics choice records the visitor’s preference |
| Google Fonts request | Deliver the selected website typefaces. Google states its Fonts Web API does not set or log cookies | Network request only | No cookie consent required for the font request itself | |
| Hosting, request logs and traffic monitoring | Vercel | Route requests, serve pages, diagnose faults, monitor traffic and protect the deployment | According to the Vercel service configuration and retention terms | Not necessarily browser storage; processed as part of hosting and security |
Definitions
Cookies and similar storage
A cookie is a small value a website asks a browser to store and return. Similar technologies include local storage, software development kits, pixels and other methods that store information on, or access information from, a device.
Under the UK Privacy and Electronic Communications Regulations, clear information and active consent are normally required before non-essential technologies run. A narrow exception applies where a technology is strictly necessary to provide a service the visitor requested.
Fonts
A request is not a cookie
Google Fonts receives an ordinary web request when the typeface files load. That request includes network information such as IP address and browser headers, but Google states that the Fonts Web API does not set or log cookies. The website privacy notice explains this processing because network information can still be personal information even without a cookie.
Hosting
Necessary security stays narrow
Vercel hosts and protects the site. Its deployment authentication can set a cookie for a protected URL. Its firewall may create a one-hour browser challenge session after a visitor passes a security check. These technologies allow the requested deployment to be delivered securely and are not controlled by the optional analytics toggle.
Vercel also provides preview tooling and feature-flag controls that may store preferences when those tools are used. Production visitors will not normally encounter preview-only tooling. We review the live deployment and this register when the Vercel configuration changes.
Consent control
Accept and reject take the same effort
The banner offers Reject optional, Choose cookies and Accept optional as equally available actions. Analytics and personalisation start off. Necessary technology remains on because it records and respects the choice or allows Arju and Vercel to deliver, authenticate and protect the requested page.
A choice is kept for 180 days. You can reopen Cookie settings from every page footer and replace it at any time. Refusing optional technology does not block the core website.
Your controls
Inspect or clear browser data
Use Cookie settings in the footer to change the stored choice. Most browsers also let you view or delete cookies and site data. Deleting the Arju consent record makes the banner ask again on your next visit.
Deleting necessary Vercel cookies can sign you out of a protected deployment or cause a security challenge to run again. Browser settings do not stop every network request. For example, Vercel hosting requests and externally hosted fonts can still involve network information even where no cookie is used.
