Privacy

Utilvia designs tools to minimize data collection. This page explains what happens to your data.

Local processing

Most Utilvia tools run entirely in your browser. Files you upload (Markdown, JSON, ICS, Instagram/TikTok exports) are processed on your device and are not sent to any server.

Cookies

We do not use tracking cookies. We may use a minimal strictly-necessary cookie to remember preferences.

Analytics

We may add privacy-respecting analytics in the future (e.g. plausible or umami). If we do, we will update this page.

Advertising

We may add ethical advertising in the future. If we do, we will use partners that respect user privacy and we will update this page.

Your rights

Since Utilvia does not collect personal data by default, there is little to exercise rights over. If you contact us with a question, we will respond and delete any correspondence you ask us to remove.
