Privacy Policy

Last updated: December 4 2025

1. Introduction

This application ("the App") is developed and provided by Per Baecklund.
This Privacy Policy explains how the App handles user data. The App is designed with privacy in mind and does not collect or store personal information.

If you have any questions, please contact: pbaecklund@gmail.com.

2. Data Collection

The App does not collect, transmit, or store any personal data about the user.
No names, email addresses, identifiers, analytics, or usage tracking are gathered.

3. Local Storage

The App allows users to create and save chemical formulas or related files.
These files are stored locally on the user's device only.

• No data stored by the user is uploaded or shared.

• The developer has no access to the locally stored files.

• Users may delete these files at any time through the App or device file system.

4. Internet Access & Third-Party Requests (PubChem)

The App retrieves publicly available chemical information from the PubChem database provided by the National Institutes of Health (NIH).

When the App requests data from PubChem:

• Standard technical information (such as the device's IP address) may be transmitted automatically as part of a normal web request.

• No personal or user-generated data is included in these requests.

PubChem's own privacy practices apply to these requests and can be found on the NIH website.

The App does not use analytics, advertising services, tracking SDKs, or any other third-party data collectors.

5. Data Sharing

The App does not share any user data with any third parties.
Since no personal data is collected, there is no data to sell, rent, or disclose.

6. Children's Privacy

The App does not collect any personal data from children or anyone else.
It is suitable for users of all ages.

7. Security

Because the App does not collect or store personal data, no server-side data security measures are required.
Local files created by the user remain under the user's control.

8. Changes to This Policy

This Privacy Policy may be updated if needed.
Any changes will be reflected by updating the "Last updated" date at the top of this page.
