Privacy Policy

Last updated: March 2026
Version: 3.0

At finzbyte.com, we build finance calculators with a "Privacy-First" architecture. We operate under a Zero-Persistence Model — your financial data stays in your browser and is never stored on our servers.

Our Guarantee

FinzByte is engineered to deliver precise financial calculations without harvesting your data.

1. Zero-Persistence Guarantee

  • No Data Logging: We do not store, log, or save any values you enter into our calculators — including income figures, loan amounts, interest rates, or investment details.
  • Local Processing: All calculations run entirely in your browser using JavaScript. Once you close or refresh the page, all input data is permanently gone.
  • No User Profiles: We do not require accounts, logins, or any form of registration to use our calculators.

2. Information We Collect Automatically

To maintain site security and improve performance, 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 general usage patterns.
  • Legal Basis (GDPR): This processing is based on Legitimate Interest (Art. 6(1)(f)) — ensuring the security and reliability of our infrastructure.

3. Cookies & Global Privacy Control (GPC)

We use minimal cookies for site performance.

  • Global Privacy Control (GPC): FinzByte 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 connections are protected via SSL/TLS encryption.

5. Your 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. You may contact us to verify our 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 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 financial resources and regulatory bodies. We are not responsible for the privacy practices of these external sites.
