Privacy Policy
Last Updated: June 29, 2026
WebDentaku ("we", "our", or "this site") respects your privacy and is committed to transparent, minimal data practices. This Privacy Policy explains how our online calculator platform handles information when you visit and use our services.
1. Zero Personal Data Collection & Client-Side Computation
All calculators available on WebDentaku (including our Desk Calculator, Scientific, Fraction, Loan, Tax, BMI, Age, Time, and Unit Converter) execute entirely within your local web browser via client-side JavaScript. None of your entered numbers, dates, monetary values, formulas, or calculated results are ever transmitted to or stored on our servers.
2. Browser Local Storage (localStorage)
We utilize standard browser localStorage solely to preserve user interface preferences across sessions:
- Theme Preference: (Key:
theme) Stores your selection between Dark Mode and Light Mode so your chosen theme is maintained upon return.
No personally identifiable information (PII) is stored in your browser storage.
3. Cookies & Tracking
WebDentaku does not deploy proprietary user-tracking cookies or account session cookies. If third-party advertising or analytics services are integrated in the future, anonymous statistical identifiers may be processed in accordance with the respective third party's privacy terms.
4. Technical Server Logs
Like virtually all standard web server architectures, our hosting infrastructure may record routine technical log entries (such as IP address, browser user-agent, requested page URL, and timestamp) strictly for server reliability, error diagnostics, and cybersecurity protection (e.g., mitigating automated denial-of-service attacks). These logs are not combined with personal user profiles.
5. External Links
Our website may contain hyperlinks to external reference websites. We have no control over and assume no responsibility for the content, privacy practices, or policies of third-party platforms.
6. Children's Privacy
WebDentaku is a general-audience educational and computational platform. We do not knowingly solicit or collect personal information from children under any jurisdiction.
7. Policy Updates
We reserve the right to modify this Privacy Policy as our services evolve or legal standards require. Any updates will be posted directly to this page with a revised effective date.
