Privacy Policy

Last updated: Feburary 2026
Version: 2.1 (2026 Compliance Update)

At CalculatorByte.com, we prioritize a "Privacy-First" architecture. Unlike many tool-based websites, we operate under a Zero-Persistence Model. This means we do not track your health metrics, financial status, or pet’s medical data beyond the immediate calculation session.

1. Our "Zero-Persistence" Guarantee

• No Data Logging: We do not store, log, or save any values you enter into our calculators (e.g., weights, dosages, or ages).
• Local Processing: Calculations are processed in real-time. Once your browser session is closed, all input data is permanently purged from your device’s temporary memory.
• No User Profiles: We do not require accounts, logins, or social media syncing to use our services.

2. Information We Collect Automatically

To maintain site security and technical reliability, we collect limited non-identifying information via standard server logs:

• Technical Data: Anonymized IP addresses, browser types, and device operating systems.
• Engagement Data: Which calculators are most visited and the duration of stay.
• Legal Basis (GDPR): This processing is based on Legitimate Interest (Art. 6(1)(f))—specifically, ensuring the security of our infrastructure and the functional accuracy of our tools.

3. Cookies & Global Privacy Control (GPC)

We use minimal cookies for site performance.

• Global Privacy Control (GPC): Consistent with 2026 regulations, CalculatorByte automatically honors GPC signals. If your browser sends a "Do Not Track" or GPC signal, we treat it as a valid opt-out for all non-essential tracking.
• Analytics: We use anonymized analytics (e.g., GA4 with IP masking) to improve tool usability. No personal information is shared with third parties for marketing purposes.

4. Data Retention & Security

• Retention Period: Technical server logs are automatically overwritten every 30 days. We do not maintain historical archives of user activity.
• Security Infrastructure: All transmissions between your device and our calculators are protected via 256-bit SSL/TLS encryption, preventing "man-in-the-middle" attacks during sensitive calculations.

5. Your Global Rights (GDPR / CCPA / CPRA)

Regardless of your location, we provide high-standard protections:

• Right to Know & Access: Because we do not store personal data or calculator inputs, we generally do not hold "records" to provide. However, you may contact us to verify our technical data practices.
• Right to Deletion: Since your inputs are never saved, there is no "data footprint" to delete from our servers.
• Minor’s Privacy: We do not knowingly collect or process data from users under 16. Our tools are for informational use by adults or under adult supervision.

6. Third-Party Links

Our calculators may cite external scientific sources (e.g., NIH, WHO). We are not responsible for the privacy practices of these external sites. We encourage you to review their policies when leaving our domain.
