Cookie Policy.

1. What Are Cookies?

Cookies are small text files stored by your browser when you visit a website. We use both cookies and browser localStorage to provide a functional, personalised experience.

2. Essential Cookies

These cookies are required for the platform to function and cannot be disabled.

• Firebase Auth Token — Set when you sign in. Expires after your session or 30 days if you choose "stay signed in". Required to authenticate your account.
• tf_theme_mode — Stores your dark/light theme preference. No personal data.

3. Analytics Cookies

We use Google Analytics to understand aggregate usage patterns (which pages are visited, session duration). These cookies do not contain personal identifiers and are anonymised before processing. You can opt out at any time using the Google Analytics Opt-out Browser Add-on.

• _ga — Google Analytics client ID. Expires after 2 years.
• _ga_* — Google Analytics session state. Expires after 2 years.

4. Advertising Cookies

We display ads from Google AdSense on most public tool, browse, and landing pages to keep the free tier free. Google and its advertising partners (including DoubleClick) may set the following cookies on your device when you visit those pages. They are used to serve ads, measure ad performance, and — depending on your consent — personalise the ads you see. They are not used to identify you personally.

• __gads — Google ad-serving cookie used to measure ad impressions and frequency-cap repeat ads. Expires after 13 months.
• __gpi — Google Publisher tag identifier used for ad personalisation and measurement. Expires after 13 months.
• IDE — DoubleClick cookie set by Google for ad measurement, reporting, and (with consent) personalisation across sites. Expires after 13 months.

You control whether Google personalises ads based on your activity. Use our cookie banner to decline advertising cookies, or manage your preferences directly at adssettings.google.com. You can also opt out of third-party personalised advertising industry-wide at youradchoices.ca (Canada) or optout.aboutads.info (US).

We do not serve ads inside the Kids Zone learning shell (signed-in child experience at /kid) or to any user signed in as a child account. Ads also are not served on this page, our Privacy Policy, Terms of Service, or Accessibility statement.

5. localStorage Keys

The following keys are written to your browser's localStorage by ToolFluency tools. They never leave your device.

• tf_theme_mode — Dark or light theme preference.
• tf_tier — Your current plan tier (free, plus, basic, suite). Used client-side to show/hide features.
• tf_recent_tools — List of recently used tool IDs for the "Recent" section on the dashboard.
• tf_toolbox_usage — Tracks which tools have been used to surface personalised suggestions.
• tf_debt_strategy — Saved strategy selection in the Debt Payoff tool (avalanche vs snowball).
• tf_hidden_suites — Which product suites you've chosen to hide from your dashboard.

All localStorage data is stored exclusively on your device. You can clear it at any time by clearing your browser's site data for toolfluency.com.
