Terms of Service

Last updated: 2025-12-01

These Terms of Service (“Terms”) govern your use of the Parta Labels mobile application (“App”) provided by æ Aeonian Engineering Limited, Hong Kong (“we”, “us”, “our”). By installing or using the App, you agree to these Terms. If you do not agree, you must not use the App.


1. Description of the Service

Parta Labels is a local-first utility tool that allows you to create, encrypt, scan, and manage QR labels. All label content is encrypted and processed on your device. Cloud functionality is not required for operation, though certain optional paid features may interact with our API.

2. Eligibility

You must be at least 16 years old, or the age of digital consent in your region, to use the App. If you are using the App on behalf of an organization, you represent that you have authority to bind that organization to these Terms.

3. Your Responsibilities

  • You are responsible for maintaining the confidentiality of your device, your master key, and any encrypted labels you generate.
  • You must not misuse the App, reverse engineer it, or attempt to circumvent its encryption logic.
  • You must not use the App to store or distribute illegal content or content that violates third-party rights.

4. Local Encryption and Data Handling

All label content is encrypted locally on your device using keys generated on your device. We do not store or access your label content. If you delete the App or lose your master key, you may lose access to encrypted data permanently. This behavior is intentional and part of the App’s security model.

5. Optional Cloud Features

Some future paid tiers may allow optional storage of master keys or metadata through secure API communication. These features are optional and require explicit user activation. Data handling and encryption rules for such features will be described in supporting documentation.

6. Advertisements

The free version of the App displays advertisements through Google AdMob. You agree to the display of ads as part of your use of the free tier. Upgrading to a paid tier may remove ads.

7. Payments and Subscriptions

Certain features are available only through paid plans. All payments are processed by Google Play and subject to its terms, including subscription renewal and cancellation procedures. We do not process or store your payment information directly.

8. Intellectual Property

The App, including its design, code, and graphics, is owned by æ Aeonian Engineering Limited and protected by international copyright and trademark laws. You may not copy, modify, adapt, or distribute any part of the App without permission.

9. Disclaimer of Warranties

The App is provided “as is” without warranties of any kind, express or implied. We do not guarantee that the App will be error-free, uninterrupted, or suitable for any specific purpose. Use of the App is at your own risk.

10. Limitation of Liability

To the maximum extent permitted by law, we are not liable for:

  • loss of access to encrypted labels or master keys,
  • any indirect, incidental, or consequential damages,
  • loss of data resulting from device failure, deletion, or corruption.

Your sole remedy for dissatisfaction with the App is to stop using it.

11. Changes to the Terms

We may modify these Terms from time to time. Continued use of the App after changes become effective constitutes acceptance of the revised Terms.

12. Termination

We may suspend or terminate your access to the App if you violate these Terms. You may stop using the App at any time by uninstalling it.

13. Governing Law

These Terms are governed by the laws of Hong Kong SAR. Any disputes shall be resolved under Hong Kong jurisdiction.
