Privacy Policy

Effective Date: 2026-07-08

1. Overview

At GraphInOut, we take your privacy seriously. This Privacy Policy explains what data we collect, why we collect it, and how we handle it. We operate under the principle of data minimization and do not use tracking cookies.

2. No Cookies

We respect your privacy and do not use cookies to track you across the web. You do not need to accept any cookie banners to use our site.

3. Analytics (Umami)

To understand how our service is used and to improve the user experience, we use Umami, a privacy-focused, cookieless analytics solution. Umami collects anonymized usage data (such as page views, referrers, and browser types) without storing any personally identifiable information. Your IP address is anonymized and not stored.

4. User-Uploaded Data

When you use GraphInOut to convert or process graphs, you transmit data to our servers. As outlined in our Terms of Service, we process this data to provide the conversion service. We also retain these uploaded graphs securely for the specific purpose of testing, debugging, and improving our parsers and related algorithms. This data is not shared publicly. Please do not upload files containing sensitive or personally identifiable information.

5. Server Logs

Like most websites, our servers may temporarily log standard technical information, such as IP addresses, access times, and user agents, for security and diagnostic purposes. These logs are routinely deleted and are not used to track individual users.

6. Your Rights

Under the General Data Protection Regulation (GDPR), you have the right to request access to, correction, or deletion of any personal data we may hold about you. Because our analytics are anonymized and we do not have user accounts, we generally cannot associate usage data with a specific person.
