Privacy Policy

Last updated: May 3, 2026

This Privacy Policy describes how Syntropy Techs ("we", "us", "our") handles information when you use the Algoritmia mobile app ("the App") on iOS, iPadOS, and Android.

1. Information we DO NOT collect

Algoritmia is designed to operate without collecting personal information. Specifically, we do not collect:

• Personal data (name, email, phone number).
• Unique device or advertising identifiers (IDFA, AAID).
• Location data.
• Usage metrics or behavioral analytics inside the App.
• Account information: the App does not require sign-up or login.
• Payment information: the App contains no in-app purchases in version 1.0.

2. Information stored locally on your device

The App stores the following information only in local storage on your device, without transmitting it to our servers or to third parties:

• Diagrams and algorithms you create (.dpa files), saved in the App's Documents directory.
• Configuration preferences, such as your chosen UI language, stored via the operating system's standard preferences mechanism.

This information remains on your device. If you uninstall the App, it is removed along with the App, except for files you have manually exported or shared.

3. Third-party services

The App uses only the following third-party service:

• Google Fonts: when you select a language whose script requires non-Latin typefaces (Chinese, Japanese, Korean, Hindi, Bengali, Arabic), the App downloads the corresponding typeface family (Noto Sans) from the public Google Fonts CDN. Google may log the IP address and user agent of the request, in accordance with its own privacy policy (policies.google.com/privacy). The App does not send Google any additional data or user identifiers.

4. Operating system permissions

The App requests the following permissions:

• Storage / file access: required to save your diagrams on the device and to let you export or share them through the operating system's standard tools (share sheet, file picker).

The App does not request access to the camera, microphone, contacts, location, notifications, or any other system resource.

5. Sharing and exporting files

When you use the share or export feature (PNG, PDF, ZIP, .dpa), the App hands the file to the operating system, which displays the native share sheet. You decide which recipient or app receives the file. The App does not participate in or log that transmission.

6. Children

Algoritmia is an educational tool suitable for users of all ages, including children under 13. Because we do not collect personal information in any way, we do not collect information from minors, and the App complies by design with the principles of COPPA (Children's Online Privacy Protection Act) and equivalent regulations.

7. Security

Information stored locally is protected by the application sandboxing mechanisms provided by the operating system (iOS/iPadOS sandbox, Android sandbox). We do not transmit sensitive information over the network.

8. Changes to this policy

We may update this Privacy Policy when we add new features or when applicable regulations change. Changes will be posted at this same URL with a new "Last updated" date. Material changes will also be announced inside the App before they take effect.
