Privacy Policy

01 —What We Collect

We inherently believe in data minimalism. Since our calculators process all algorithms directly in your browser using JavaScript, we do not monitor, store, or transmit your individual numeric inputs (e.g., your salary, your weight, your age).

We collect high-level, anonymous usage statistics. This consists of recognizing that a specific calculator was used and general traffic metrics (like page views) without associating this data with personal identities (PII).

02 —How We Use Information

The strictly anonymous traffic data we collect is utilized exclusively to maintain the health of the platform and to guide our future development roadmaps. If we notice the "Compound Growth" calculator gaining massive popularity, we know to prioritize investing time into similar financial tools.

We never sell analytical logs to third-party data brokers under any circumstances.

03 —Cookies & Local Storage

CalculiX Pro intentionally minimizes cookie usage. We utilize your browser's native LocalStorage to save non-sensitive UI preferences — such as whether you prefer the "Dark Mode" or "Light Mode" theme, or preserving your active list in the Subscription Tracker.

These preferences live on your device and are never transmitted to our backend databases.

04 —Third-Party Services

To support the ongoing free availability of our platform, we utilize Google AdSense to serve contextual advertisements. We may also use Google Analytics to monitor structural traffic metrics.

These third parties may utilize standard web cookies to deliver optimized advertisements. You can manage or opt-out of personal ad tracking directly through your Google preferences.

05 —Data Security

The absolute best way to secure personal data is to simply never collect it. We do not run a user-account system, meaning there are no passwords to leak. All connections between you and our web servers are securely encrypted using industry-grade HTTPS/TLS protocols.

06 —Contact & Changes

The digital landscape shifts rapidly, and we reserve the right to append or modify this Privacy Policy to reflect those updates. Any fundamental changes will be reflected by the date at the top of this page.

If you have specific concerns regarding privacy architecture, please reach us via the Contact Page.
