Cookie Policy
Last updated: April 17, 2026
This page explains every cookie and local-storage item this site uses, what it's for, how long it stays, and how to decline the optional ones. It's the companion to our Privacy Policy, which covers the broader data practices behind the site.
What Cookies Are (and Aren't)
A cookie is a small text file that a website stores in your browser so it can recognize you on the next visit. Some are strictly necessary for a site to work. Others are optional — they help the site owner understand how pages are used, or let advertisers serve relevant ads. This site uses a small set of both, and every optional cookie is off until you click Accept on the consent banner.
We also use localStorage for a handful of user-preference settings (theme, font size, accessibility toggles). localStorage is similar to a cookie but it never leaves your device and is not sent to any server.
Cookies We Set
Every cookie and localStorage item this site may use is listed below. The Category column tells you whether we set it before or after your consent.
| Name | Provider | Purpose | Category | Storage | Duration |
|---|---|---|---|---|---|
cookie-consent |
jwatte.com | Remembers whether you accepted or declined the consent banner. | Strictly necessary | localStorage | Until cleared by you |
jw-theme, fontScale, contrast, reading-guide |
jwatte.com | Accessibility preferences — dark/light theme, font scale, contrast mode, reading guide toggle. | Strictly necessary | localStorage | Until cleared by you |
analyzer-skill-level, cvm-history-v1, batch-snapshots |
jwatte.com | Your preferences and saved snapshots inside the free SEO tools at /tools/. Nothing here is sent anywhere; it's only readable by this site in your browser. | Strictly necessary | localStorage | Until cleared by you |
_ga, _ga_* |
Google Analytics 4 (Google LLC) | Anonymous usage analytics — which pages are read, how long, where visitors arrive from. | Optional (opt-in) | Cookie | Up to 2 years |
_clck, _clsk, CLID, MR, MUID, SM |
Microsoft Clarity (Microsoft Corporation) | Session replay and heatmap analytics. Clarity does not collect personally identifiable information. | Optional (opt-in) | Cookie | Up to 1 year |
__gads, __gpi, IDE, DART and related Google ad cookies |
Google AdSense (Google LLC) | Display-advertising cookies set by Google when ad slots are present. Only activates on pages that render an AdSense unit. | Optional (opt-in) | Cookie | Up to 2 years |
Strictly Necessary vs Optional
The items marked Strictly necessary are set by this site before you click anything. They store the consent choice itself, the accessibility preferences you've set, and the local tool state for the free SEO tools. None of them track you across other sites, none are sent to a server, and none can be used to identify you.
The items marked Optional are third-party cookies for analytics and advertising. They are not set unless you click Accept on the consent banner. If you decline, the Google Analytics and Clarity scripts don't load at all, which is stricter than the typical "category-based" consent most sites offer.
How to Change Your Mind
If you previously accepted and want to revoke consent, or previously declined and want to opt in:
- Open your browser's developer tools (F12 or right-click → Inspect).
- Go to Application → Local Storage →
https://jwatte.com. - Delete the
cookie-consentkey. - Refresh the page — the consent banner will reappear.
Or, more directly, clear your browser's site data for jwatte.com and the banner will reappear on your next visit. Clearing site data removes all localStorage (including accessibility preferences and saved tool snapshots).
Third-Party Opt-Outs
You can opt out of the analytics and advertising providers directly, even without declining the banner:
- Google Analytics — install the Google Analytics Opt-out Add-on in your browser.
- Google Ads personalization — adjust preferences at Google Ad Settings.
- Microsoft Clarity — Clarity respects the browser's Do Not Track signal. Enable DNT in your browser settings to opt out.
- Industry-wide — DAA WebChoices (US) or YourOnlineChoices (EU) let you opt out of personalized ads across many providers at once.
Do Not Track and Global Privacy Control
This site respects the Global Privacy Control (GPC) signal where supported by your browser. If your browser sends a DNT or GPC header, the consent banner will default to declined for optional cookies. You can still explicitly accept via the banner if you prefer.
Cookies Set by Content You Interact With
Some pages embed third-party content (YouTube video players, Amazon book-purchase links). Clicking into those embeds may cause the third party to set its own cookies on their domain — this site has no visibility into or control over those. See each provider's privacy policy for detail: Google, Amazon.
Changes to This Policy
We'll update this page whenever cookies are added, removed, or their purpose changes. The Last updated date at the top of the page reflects the most recent change. Material changes are also reflected in the consent banner text so returning visitors see the update.
