Privacy Policy

Last updated: March 2026

Overview

Konvertio is built with your privacy as a core principle. We believe you should be able to use online tools without sacrificing your personal data. All processing is performed entirely in your browser — no data is sent to any server.

No Data Collection

We do not collect, store, or process any personal information. Every operation you run happens locally in your browser using client‑side JavaScript. Your inputs and results never leave your device.

No Tracking Cookies

Konvertio does not use cookies for tracking, advertising, or profiling. We do not set any third‑party cookies. If your browser stores any data locally (such as theme preference), it stays on your device and is never transmitted.

No User Accounts

We do not require sign‑ups, logins, or user accounts of any kind. There is no personal data stored because there are no accounts to store it in. You can use every tool on Konvertio completely anonymously.

No Third-Party Analytics

We do not use Google Analytics, Facebook Pixel, or any other third‑party analytics or tracking services. We may use minimal, privacy‑respecting, cookie‑free analytics to understand aggregate page views, but no personal data or IP addresses are ever collected or stored.

No Data Sharing

Since we do not collect any data, there is nothing to share. We do not sell, rent, trade, or otherwise transfer any information to third parties — because we simply don't have any.

Third-Party Links

Konvertio may contain links to external websites. We are not responsible for the privacy practices of those sites and encourage you to review their privacy policies independently.

Changes to This Policy

If we make changes to this privacy policy, we will update the "Last updated" date at the top of this page. We encourage you to review this page periodically.
