Privacy Policy
Your privacy matters to us. This policy explains what data we collect, how we use it, and your rights as a user of YayKyi.
- ✓ All tool calculations happen in your browser — we never see your inputs.
- ✓ We collect only anonymous usage analytics.
- ✓ We never sell your data to anyone.
- ✓ You can opt out of analytics at any time.
1. Information We Collect
YayKyi is designed with privacy as a core principle. The vast majority of our tools perform all calculations entirely within your browser — no data is sent to our servers.
We may collect the following minimal, anonymous information:
• Usage analytics: Page views, session duration, and feature interactions (via Google Analytics, anonymized).
• Error logs: Crash reports to help us fix bugs (no personal data included).
• Cookies: Session cookies for basic functionality and analytics preferences.
We do NOT collect: names, email addresses, health data, relationship data, financial data, or any personally identifiable information entered into our tools.
2. How We Use Information
The limited data we collect is used solely to:
• Improve tool performance and fix bugs
• Understand which tools are most useful to our users
• Optimize page load times and user experience
We do not use your data for advertising targeting, profiling, or any commercial purpose beyond operating the platform.
3. Third-Party Services
We use the following third-party services, each with their own privacy policies:
• Google Analytics: Anonymous usage tracking. You can opt out via Google's opt-out browser add-on.
• Google AdSense: May display ads. Google may use cookies to show relevant ads.
• Vercel: Our hosting provider. See Vercel's privacy policy for infrastructure data handling.
We do not sell, rent, or share your data with any other third parties.
4. Cookies
We use the following types of cookies:
• Essential cookies: Required for basic site functionality (e.g., remembering your preferences).
• Analytics cookies: Anonymous data to help us understand how users interact with our tools.
• Advertising cookies: Set by Google AdSense for ad relevance (can be disabled in your browser).
You can disable cookies in your browser settings at any time. Most of our tools will continue to function without cookies.
5. Data Storage & Security
Tool inputs and results are processed entirely in your browser and are never transmitted to our servers. Some tools use your browser's localStorage to save your preferences between sessions — this data stays on your device and is never sent to us.
We implement industry-standard security practices for any data that does pass through our infrastructure (e.g., contact form submissions).
6. Children's Privacy
YayKyi is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will promptly delete it.
7. Your Rights
Depending on your location, you may have the following rights:
• Access: Request a copy of any personal data we hold about you.
• Deletion: Request deletion of your personal data.
• Opt-out: Opt out of analytics tracking at any time.
• Portability: Request your data in a portable format.
To exercise any of these rights, contact us at hello@yaykyi.com.
8. Changes to This Policy
We may update this Privacy Policy from time to time. We will notify users of significant changes by updating the "Last Updated" date at the top of this page. Continued use of YayKyi after changes constitutes acceptance of the updated policy.
