Terms and Conditions

Diffractor is free software. It may be redistributed and/or modified under the terms of the GNU Lesser General Public License (LGPL), version 2.1 or any later version. License details: https://www.gnu.org/licenses/lgpl-2.1.html.

The Diffractor application is governed by its End User License Agreement (EULA). By installing or using the application, the user agrees to the EULA.

Software and documentation made available for download from this website are subject to the terms contained in those materials. If any conflict exists, the EULA and applicable open‑source licenses control.

Privacy Statement

Diffractor respects privacy. Personal information is not sold or traded.

Crash diagnostics: When the application crashes, it may send diagnostic information (which can include basic system details) to help improve reliability. Diagnostic data is designed to be anonymous, is retained for no longer than 30 days, and can be disabled in the application options.

Automatic updates: The application can check for and download updates from diffractor.com. This may involve contacting Diffractor web services to determine whether a new version is available. Automatic updates can be disabled in the application options.

Payments: Payments processed via PayPal are governed by PayPal’s own legal agreements.

User Data Deletion

Uninstalling the application removes cached user data. Diffractor does not store user data online, and it does not upload photos or videos.

Cached thumbnails and metadata are stored locally at C:\Users\[username]\AppData\Local\Diffractor\diffractor-cache.db. Original photos and videos remain in the folders where the user saved them and are not deleted by uninstalling the application.

Cookies

The Diffractor website aims to avoid the use of cookies. If any cookies are present, they are limited to those that are strictly necessary for the site to function. Third‑party services (for example, PayPal) may set their own cookies in accordance with their policies.

Except as required by law, the website and application are provided “as is” without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non‑infringement. To the maximum extent permitted by law, Diffractor and its operators will not be liable for any indirect, incidental, special, consequential, or punitive damages arising out of or relating to use of the website or application.
