Privacy Policy

Last updated: August 19, 2026

1. Purpose of this Privacy Policy

This Privacy Policy explains how Qreck processes data in connection with its mobile application and its website available at https://www.qreck.com.

Qreck is an application that allows users to create and display QR Codes containing different types of information or links, including contact details, email addresses, URLs, text, and links to online services or social networks.

Qreck is designed to work without requiring an account.

The application can also operate without an Internet connection once its content has been loaded.

2. Data Controller and Contact

Qreck is published by an independent developer.

For any questions regarding this Privacy Policy or the processing of data, you can contact:

contact@qreck.com

This address may also be used to exercise your rights where applicable.

3. Data Entered by the User

Qreck allows users to freely create QR Codes and associate them with content of their choice.

Users may add, in particular:

  • a telephone number;
  • an email address;
  • an address;
  • a URL;
  • a link to a social network;
  • a link to a channel or online service;
  • text;
  • or any other link or content supported by the application.

This information is stored locally on the user's device.

In the current version of Qreck, the content of these QR Codes is not automatically sent to the Qreck server.

The main operation of the application therefore does not require this information to be transmitted to Qreck.

4. Offline Operation

Qreck is designed to operate even when the device does not have an Internet connection.

QR Codes created by the user remain available locally when the network is unavailable.

Some features requiring communication with Qreck servers can naturally only operate when an Internet connection is available.

5. Installation Identifier

In order to measure application usage and distinguish installations for statistical purposes, Qreck generates a unique random identifier for each installation.

This identifier is generated using the standard crypto.randomUUID() function.

It is not:

  • the user's telephone number;
  • the user's email address;
  • the user's name;
  • the user's Google account;
  • the device's advertising ID;
  • or a hardware identifier such as the IMEI.

This identifier is used solely for the technical and statistical purposes of Qreck.

6. Usage Statistics

Qreck uses an internal statistics system to understand how the application is used and to improve its operation.

Events that may be recorded may include, for example:

  • the display of a feature;
  • the opening of a screen;
  • the creation of a QR Code;
  • the display of a QR Code;
  • the modification of a QR Code;
  • or the use of other application features.

Statistical data may include:

  • the installation identifier;
  • the type of event;
  • the date and time of the event;
  • certain technical information required for the operation of the service.

The statistical system is not intended to record the content of QR Codes created by the user.

In particular, usage events do not intentionally contain:

  • telephone numbers entered into QR Codes;
  • email addresses entered into QR Codes;
  • URLs entered into QR Codes;
  • text contained in QR Codes;
  • or the content of the QR Codes themselves.

7. Deferred Transmission of Statistics

As Qreck can operate offline, statistical events may be temporarily stored locally on the device when no Internet connection is available.

When the Internet connection becomes available again, pending events may be transmitted to the Qreck server.

This transmission is performed asynchronously and does not affect the main operation of the application.

Events are removed from local storage after successful transmission.

8. IP Addresses and Technical Information

When communication with Qreck servers takes place, technical information related to the connection may be available at server level, including the IP address used to establish the connection.

To limit the precision of information retained for technical purposes, IPv4 addresses that may be stored in certain technical data are truncated.

Full IP addresses are not used in the internal usage statistics system described in this Privacy Policy.

Technical information may be used in particular to:

  • ensure server security;
  • detect abnormal or abusive behavior;
  • diagnose technical issues;
  • maintain the service;
  • analyze and resolve errors.

9. Technical Logs

Qreck servers may generate technical logs necessary for operating and securing the service.

These logs may contain technical information relating to requests, errors, or server operation events.

Technical logs are retained for a maximum period of 90 days, unless a longer retention period is necessary to comply with a legal obligation, resolve a security incident, or establish, exercise, or defend legal claims.

10. Retention of Statistical Data

Statistical data is retained for a maximum period of 12 months.

At the end of this period, the relevant data is deleted or rendered unusable for the original statistical purposes.

This period may be adjusted in the future if the operational or analytical needs of Qreck evolve. In such cases, this Privacy Policy may be updated accordingly.

11. Cookies and Local Storage

Qreck does not use cookies for advertising or advertising tracking purposes.

The application and website may use local storage mechanisms that are necessary for their operation.

Local storage is used in particular to store QR Codes created by the user and to allow the application to operate offline.

These local data are not automatically transmitted to the server simply because they are present on the device.

12. Hosting and Infrastructure

The server services of Qreck are hosted on Amazon Web Services (AWS) infrastructure, currently located in the US East (N. Virginia) — us-east-1 region.

Data transmitted to Qreck servers may therefore be processed on this infrastructure.

International transfers or processing of data outside the European Economic Area may therefore occur.

Where required by applicable law, international data transfers are subject to the appropriate legal mechanisms.

13. Data Sharing

Qreck does not sell users' data.

Content created locally by the user in QR Codes is not transmitted by Qreck to social networks, advertising networks, or data brokers.

Technical and statistical data may be processed on the hosting infrastructure used to operate Qreck services.

No data is shared for behavioral advertising purposes.

14. No User Account Required

Normal use of Qreck does not require the creation of an account.

The application therefore does not require, for normal use:

  • a name;
  • an email address;
  • a telephone number;
  • a password;
  • or a social network account.

The remote backup feature for QR Codes is not available in the current version of Qreck.

15. Security

Qreck implements technical measures designed to protect processed data against unauthorized access, loss, alteration, or disclosure.

Communications between the application and Qreck servers are carried out using HTTPS.

The architecture of Qreck also prioritizes local processing and storage of user-created content in order to limit the data transmitted to the servers.

16. Children's Data

Qreck is not specifically intended for children.

The application does not ask for the user's age and does not require an account to use its main features.

Users are responsible for the content they choose to store in their QR Codes and should avoid storing or sharing personal data relating to other individuals without having a lawful basis to do so.

If a parent or legal guardian believes that a child has provided personal data to Qreck in circumstances requiring intervention, they may contact:

contact@qreck.com

17. Rights Relating to Personal Data

Depending on the regulations applicable to your situation, you may have various rights regarding personal data concerning you, including:

  • the right of access;
  • the right to rectification;
  • the right to erasure;
  • the right to restriction of processing;
  • the right to object;
  • the right to data portability where applicable.

To exercise your rights or obtain further information, you can contact:

contact@qreck.com

We will respond to your request within the time limits provided by applicable law.

Where necessary to protect data and prevent fraudulent requests, additional information may be requested to verify the identity of the requester.

18. Supervisory Authority

If you believe that the processing of your personal data does not comply with applicable regulations, you may contact the competent supervisory authority in your country or place of residence.

For individuals subject to French data protection regulations, the competent supervisory authority is notably the Commission nationale de l'informatique et des libertés (CNIL).
