Privacy Policy
Last Updated: June 5, 2026
1. Introduction
At UltiCalculator, we believe that your data is yours. We built this application with a strict "privacy-first" and "offline-first" mentality. This means we are mathematically and architecturally committed to protecting the confidentiality of the information you input into our calculators.
2. Data Collection and Storage
We do not collect, transmit, or store your personal data on external servers.
- Local Processing: All mathematical and financial computations (such as BMI results, amortization schedules, and scientific calculations) occur entirely within your device's browser. There is no backend server receiving your input variables.
- Local Storage: If you use certain features (e.g., custom formulas, theme preferences, calculator history), that data is saved exclusively using your browser's local cache or
localStorage. It never leaves your device. - No User Accounts: We do not require account registration, and we do not maintain profiles, identities, or accounts linked to you.
3. Third-Party Services and Analytics
To monitor basic website performance, uptime, and general non-identifiable usage statistics, we may utilize minimal, privacy-compliant analytics tools (e.g., Google Analytics).
- These tools are restricted from cross-site tracking and only collect high-level metrics such as visit counts and page load speeds.
- No ad-tracking networks or fingerprinting scripts have been embedded in our calculator utilities.
Additionally, our AI Assistant ("Ulti") interacts with the Gemini AI model to answer generalized queries. We explicitly strip any personal data before interacting with the LLM API, ensuring prompts are untraceable and anonymous.
4. Use of Device Resources
By utilizing our calculators, our application makes use of your device's processing power (CPU) and memory (RAM) temporarily to execute calculations or to generate documents (such as PDF generation via jsPDF). This processing is strictly client-side and sandboxed within modern browser security constraints.
5. Your Rights and Data Control
Because we do not transmit or store your inputs externally, you are in complete control of your data.
- Data Deletion: You can erase all saved histories, preferences, and cached inputs instantly at any time by clearing your browser's history and website data cache.
6. Changes to this Policy
We may occasionally update this Privacy Policy to reflect changes in web standards or application features. When changes are made, we will update the "Last Updated" date at the top of this document. We encourage you to review this page periodically.
7. Contact
If you have questions about how our software handles data locally, you can reach out via our general support channels or use the integrated Ulti Assistant for guidance on how the tools ensure your privacy.
