Privacy Policy – Parta Labels

Local-only encrypted label app

Last updated: 10 December 2025

Parta Labels (“the App”) is developed and maintained by æ Aeonian Engineering Limited (Hong Kong) and WIDE di D. Papa (Italy) (collectively “we”, “us”, “our”).

This Privacy Policy explains how the App handles information. The short version is: we do not collect, store or sell your personal data. All label content and keys stay on your device, and only you decide if and how to share them.

1. Data Collection

The App itself does not collect personal data.

Specifically, the App does not:

  • require you to create an account or log in;
  • collect your name, email address, phone number, or postal address;
  • upload your labels, master keys, or QR codes to our servers;
  • track your activity across other apps or websites.

On-device data only

All label content and master keys are encrypted and stored locally on your device. We cannot access or recover your data.

2. Encryption and Security

The App uses AES-based client-side encryption to protect your labels. Encryption keys are generated on your device and stored using the platform’s secure storage APIs.

We never receive your encryption keys or your label content. If you lose your master key or printed/QR backups, we cannot restore your data for you.

3. Camera Use

The App uses the device camera only to scan QR codes. The camera feed is processed locally and is not sent to our servers.

4. Sharing and Export

The App can generate QR codes or files (for example, a PDF) that you may choose to export or share using the operating system’s native share dialog.

When you share something, it is handled by your device and the apps you select (for example, email, messaging, or cloud storage). We do not know what you share, where you share it, or with whom.

5. Advertising and Advertising ID

Parta Labels displays advertising provided by Google AdMob. For this purpose, Google may use an Advertising ID or similar device identifiers to:

  • serve ads within the App;
  • measure ad performance;
  • limit the number of times you see the same ad.

We do not have direct access to the Advertising ID and we do not combine it with any personal information. For more information on how Google uses data in advertising, please see: https://policies.google.com/technologies/ads .

You can control ad personalization in your Google account settings or your device’s ad/privacy settings.

6. Children’s Privacy

The App is intended for users aged 16 and over. It is not designed for children and does not knowingly collect personal information from children.

7. Third-Party Services

The App uses the following third-party service:

  • Google AdMob – to display advertisements.

These services are provided by Google. Their use of data is governed by Google’s own privacy policy: https://policies.google.com/privacy .

8. Data Safety and Your Rights

Because we do not collect or store your personal data on our servers, most data protection rights (access, deletion, correction, portability) are handled directly on your device by you.

If you are in the EU/EEA, UK or other regions with specific privacy laws and have questions about how the App handles information, you can contact us using the details below.

10. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will update the “Last updated” date at the top of this page. Continued use of the App after changes are published means you accept the revised policy.
