Privacy Policy

Last Updated: July 27, 2026

Project OpenCraft ("Project OpenCraft", "we", "our", or "us") respects your privacy.

Our mission is to create free, privacy-first Android applications that work offline whenever possible, contain no advertisements, avoid unnecessary tracking, and request only the permissions genuinely required to deliver their intended functionality.

This Privacy Policy explains how we collect, use, disclose, and protect information when you use our website, applications, and related services (collectively, the "Services").

By using our Services, you agree to the practices described in this Privacy Policy.

1. Our Privacy Principles

Everything we build follows these guiding principles:

• Privacy First

• Offline First

• No Advertisements

• No User Tracking

• Minimal Permissions

• Transparent Data Practices

Whenever technically possible, processing takes place entirely on your own device.

2. Information We Collect

Most Project OpenCraft applications are designed so that we do not collect or receive your personal information.

Unless a specific feature clearly requires it, we do not intentionally collect:

• Your name

• Email address

• Phone number

• Postal address

• Contacts

• Messages

• Photos

• Videos

• Documents

• Precise location

• Advertising ID

• Device identifiers used for tracking

• Browsing history

• Usage history across other apps

• Payment information

• Biometric information

Many of our applications function without requiring any personal information.

3. Information Stored on Your Device

Some applications may store information locally on your device to improve functionality.

Examples include:

• User preferences

• Application settings

• Saved calculations

• Offline databases

• Recently opened files

• User-created content

• Cached information

• Custom themes

• Favorites

• Local history

Unless specifically stated, this information remains on your device and is not transmitted to Project OpenCraft.

4. Permissions

Our applications request only the permissions necessary to provide their intended functionality.

Depending on the application, requested permissions may include:

• Camera (document scanning, barcode scanning, image capture)

• Microphone (voice input or recording features)

• Storage or media access (opening or saving files)

• Notifications (optional reminders or alerts)

• Internet access (features requiring live information)

Permissions are requested only when required and, where supported by Android, at the time they are needed.

You may deny or revoke permissions through your device settings at any time, although doing so may limit certain features.

5. Internet Connectivity

Most Project OpenCraft applications are designed to operate completely offline.

An internet connection is only required for features that depend on current or remotely maintained information, including but not limited to:

• Currency exchange rates

• Weather information

• Solar and lunar data

• Online AI features

• Public databases

• Live APIs

• Cloud synchronization (if offered)

• Software update checks

• Other time-sensitive information

Core functionality is intended to remain available without internet access whenever reasonably possible.

6. AI Features

Some Project OpenCraft applications include AI-assisted features.

Depending on the application, AI processing may occur:

• Entirely on your device

• Using locally hosted AI models

• Through trusted third-party AI providers when online processing is required

When cloud-based AI services are used, only the information necessary to process your request is transmitted.

We strive to minimize the amount of information shared and to avoid retaining unnecessary data.

7. Open-Source Software and Third-Party Services

Our applications may use:

• Open-source software

• Community-maintained libraries

• Public APIs

• Public datasets

• AI services

• Operating system services

These technologies remain subject to their own licenses, terms, and privacy practices.

Project OpenCraft does not control third-party services and is not responsible for their privacy policies or operational practices.

8. Advertising and Tracking

Project OpenCraft is committed to providing an experience free from unnecessary surveillance.

Our applications are designed not to intentionally include:

• Advertising SDKs

• Behavioral profiling

• Cross-app tracking

• Interest-based advertising

• User profiling

• Sale of personal information

• Third-party advertising networks

If a future application requires optional analytics or diagnostic reporting, this will be clearly disclosed within that application, and, where appropriate, you will be given the choice to enable or disable it.

9. Cookies

Our website may use cookies or similar technologies that are necessary for:

• Website functionality

• Security

• Performance

• User preferences

Where required by applicable law, you will have the ability to manage your cookie preferences.

We do not use cookies to build advertising profiles or track your activity across unrelated websites.

10. Bug Reports and Feedback

Some applications include a Report Bug feature.

If you voluntarily submit a bug report, you may choose to provide information such as:

• Device model

• Android version

• App version

• Error descriptions

• Screenshots

• Log files

• Other information you decide to include

This information is used solely for diagnosing, reproducing, and resolving software issues or improving our applications.

Submitting a bug report is entirely voluntary.

11. Data Security

We use reasonable administrative, technical, and organizational measures to help protect information under our control.

However, no method of electronic storage or internet transmission can be guaranteed to be completely secure.

Accordingly, we cannot guarantee absolute security of any information.

12. Data Retention

Because most Project OpenCraft applications do not collect personal information, we generally do not retain personal data.

If you voluntarily contact us or submit bug reports, we may retain that information only for as long as reasonably necessary to:

• Respond to your request

• Investigate reported issues

• Improve our applications

• Comply with applicable legal obligations

13. Children's Privacy

Our Services are intended for a general audience unless otherwise specified.

We do not knowingly collect personal information from children.

If you believe that a child has provided personal information to us, please contact us, and we will take reasonable steps to remove that information where appropriate.

14. International Users

Project OpenCraft applications may be downloaded and used worldwide.

By using our Services, you understand that information you voluntarily provide may be processed in accordance with applicable laws.

15. Third-Party Websites

Our website and applications may contain links to third-party websites or services.

Project OpenCraft is not responsible for the privacy practices, content, security, or availability of third-party websites.

We encourage users to review the privacy policies of any external websites they visit.

16. Your Rights

Depending on your location and applicable laws, you may have certain privacy rights, including the ability to:

• Request access to personal information you have voluntarily provided

• Request correction of inaccurate information

• Request deletion of personal information we hold about you

• Withdraw consent where processing is based on consent

• Contact us regarding privacy concerns

Because most Project OpenCraft applications do not collect personal information, many of these rights may not apply in practice.

17. Disclaimer

While we make every reasonable effort to develop reliable and secure software, no software can be guaranteed to be completely free of bugs, vulnerabilities, interruptions, or inaccuracies.

Project OpenCraft is not responsible for any loss, damage, injury, expense, or other consequences resulting from:

• Incorrect calculations

• AI-generated inaccuracies

• Outdated information

• Software defects

• API failures

• Third-party services

• User decisions based on application output

• Misuse of our applications

Users should independently verify important information before relying upon it for financial, legal, medical, engineering, educational, scientific, or safety-related decisions.

18. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our applications, legal requirements, or operational practices.

The most current version will always be published on the official Project OpenCraft website.

Your continued use of our Services after changes become effective constitutes acceptance of the revised Privacy Policy.
