Privacy Policy

Last updated: August 19, 2026

1. Overview

Ovucal is designed to be privacy-first. You can use our calculators without creating an account or providing your name. This policy explains what information may be processed when you visit the site.

2. Calculator Inputs

Inputs such as period dates, cycle lengths, and related calculator values are processed in your browser to display results. Ovucal does not require these inputs to be stored in a user profile or submitted to a health database.

3. Analytics and Consent

Google Analytics is optional and remains disabled unless you select “Allow analytics” in the privacy choices shown on the site. When enabled, it helps us understand aggregate traffic, page performance, device types, and general usage. Calculator dates and health-related entries are not intentionally sent as analytics event data. You can reopen the privacy choices from the site footer.

4. Email and Support Messages

If you contact us by email, we may receive your email address and the information you choose to include. Please do not send sensitive medical records or highly personal health details.

5. Advertising

If advertising is added to Ovucal, advertising partners such as Google may use cookies or similar technologies to serve, limit, personalize, and measure ads. These technologies may use information such as your browser, device, general location, pages visited, and ad interactions. Ovucal aims to keep advertising separate from calculator inputs and health estimates.

You can manage cookies through your browser settings. Google also provides ad personalization controls through its own privacy and advertising settings. If AdSense is enabled, Google's advertising policies and privacy practices apply to ad delivery and measurement.

6. Third-Party Links

Ovucal may link to third-party websites for reference or resources. We are not responsible for the privacy practices of external sites.

7. Data Retention

Calculator inputs entered on the page are not intended to be stored in a personal account. Support emails may be retained as needed to respond to messages, prevent abuse, and maintain records of corrections or requests.

8. Contact

For privacy questions, contact support@ovucal.com.

How we maintain quality

Ovucal explains calculator assumptions, uncertainty, and situations where professional care matters. Calculator inputs are processed in the browser and no account is required.

Optional Google Analytics loads only after consent. Calculator dates and health-related entries are not intentionally sent as analytics event data.

If advertising is enabled, ads must remain separate from calculator results and editorial decisions. A Google-certified consent platform must be configured where required.
