Privacy Policy

    Last updated: February 2026

    At ToolKit, we take your privacy seriously. This policy explains what data we collect, how we use it, and your rights regarding your information.

    The Short Version

    All calculations run in your browser. We don't upload, store, or have access to the data you enter into our tools. We use cookies for basic analytics and, if you use the free version, for serving ads. We never sell your personal information to third parties.

    Data We Collect

    Data You Enter Into Tools

    When you use a  calculator or converter on ToolKit, all processing happens directly in your  web browser. The numbers, text, and other data you input are never transmitted to our servers. We cannot see, access, or store this information.

    Local Storage

    Some features use your browser's local storage to remember preferences or track usage limits (for free tier users). This data stays on your device and is never sent to us. You can clear this data at any time through your browser settings.

    Analytics

    We use Google Analytics to understand how people use our site—which pages are popular, how users navigate, and general demographic information. This helps us improve our tools and prioritize new features. Google Analytics uses cookies and collects anonymized data about your visit.

    Third-Party Services

    Google AdSense

    Free users may see advertisements served by Google AdSense. Google uses cookies to serve ads based on your browsing history across different websites. You can opt out of personalized advertising through Google's Ad Settings or by visiting aboutads.info.

    Dictionaries & Encyclopedias

    Payment Processing

    If you upgrade to Pro, your payment is processed by Stripe. We never see or store your full credit card number. Stripe's privacy policy governs how they handle your payment information.

    Cookies

    We use cookies for:

    • Essential site functionality
    • Analytics (Google Analytics)
    • Advertising (Google AdSense, free users only)
    • Remembering your preferences

    Most browsers allow you to control cookies through settings. Disabling cookies may affect some site features.

    Data Retention

    Since we don't collect personal data from your tool usage, there's nothing to retain or delete. Analytics data is retained according to Google's standard policies (currently 26 months). If you contact us, we retain those  communications to provide support.

    Enterprise Technology

    Your Rights

    Depending on your location, you may have rights including:

    • Access to data we hold about you
    • Correction of inaccurate data
    • Deletion of your data
    • Opting out of data collection
    • Data portability

    Children's Privacy

    ToolKit is not directed at children under 13. We don't knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us.
