Privacy Policy

1. Who is the controller of personal data

This Notice applies in particular to services operated under the domains justmeasure.cz, app.justmeasure.cz and license.justmeasure.cz.

2. What personal data we process

2.1 Contact and customer data

• email address,
• name of the contact person, if provided,
• company or other billing entity,
• Company ID, VAT ID and billing address, if provided or necessary for the commercial relationship.

2.2 License and activation data

• public license ID, license plan and major license version,
• license-key hash; the full license key is not stored in readable form in the database,
• license status, date of issue and any expiry date,
• technical device identifier deviceId and any user-defined device name,
• data relating to activation, validation, deactivation and license recovery,
• license-token hash; the full token is not stored in readable form in the database.

2.3 Technical and security data

• IP address,
• application version and major JustMeasure version provided to the licensing API,
• time and type of significant licensing or administrative events,
• technical error and security logs necessary to operate the service.

2.4 Records of legal documents

We store information identifying the specific version and language of the License Terms accepted by the user and the specific version and language of the Privacy Notice presented during registration or when starting a Trial. The record may include the date and time, IP address, source of the operation and identification of the license or contact.

3. What is not uploaded during license verification

During standard license activation and validation, the JustMeasure licensing backend does not receive the contents of your drawings, photographs or .justm project files.

During ordinary use, drawings and projects remain on the user’s device. If JustMeasure later offers a separate cloud function requiring transfer of such data, that processing will be described separately before the function is used.

4. Why we process data and the legal basis

An email address obtained for a Trial or license management is not, solely for that reason, automatically added to a marketing newsletter.

5. Trial and prevention of repeated use

A Trial can normally be used only once on a particular device. For this purpose, we keep a technical device identifier and a record that the Trial was used. This processing protects the licensing model against repeated circumvention of the Trial limit.

6. How long we retain data

• Active licenses and customer data: for the duration of the licensing relationship and thereafter for the period necessary to settle rights and obligations and protect legal claims.
• Records of legal-document acceptance: for as long as they may be relevant to demonstrating the creation and content of the licensing relationship and thereafter according to applicable limitation periods.
• Accounting and tax data: for the period required by applicable law if such data arises in connection with paid sales.
• Activation and security logs: for the period necessary to secure the service, handle incidents and protect against misuse; the period may vary according to the type of record.
• Record of Trial use: for as long as necessary to enforce the one-Trial-per-device rule, at most for as long as this licensing model is used.

Specific retention periods are reviewed over time with regard to the purpose of processing, legal obligations and the data-minimisation principle.

7. Who may receive the data

Personal data may be made available to the extent necessary in particular to:

• the web-hosting and server-infrastructure provider,
• an email-service provider if used to deliver licensing or operational messages,
• the payment provider and entities providing accounting or invoicing services if you make a paid purchase and those services are involved,
• public authorities where disclosure is required by law.

Processors may use the data only to the extent necessary to provide their services and in accordance with the relevant contractual and legal obligations.

8. Transfers outside the European Economic Area

At the effective date of this version, the basic licensing backend is not designed to intentionally transfer license and customer data outside the European Economic Area. If a provider is later engaged whose use requires such a transfer, appropriate legal safeguards will be used before that processing begins and this document will be updated.

9. Local storage in the application

JustMeasure may use local browser storage, in particular to retain the technical device identifier, local license state and license token. These data allow the particular installation/browser to be identified to the licensing backend.

Use of local storage for technically necessary licensing functions is not intended for advertising profiling.

10. Your rights

To the extent provided by applicable law, you may in particular request:

• access to your personal data,
• rectification of inaccurate or incomplete data,
• erasure where the data are no longer necessary or there is no other legal ground for retaining them,
• restriction of processing,
• data portability where the statutory conditions are met,
• the right to object to processing based on legitimate interests.

A request can be sent to podpora@justmeasure.cz. Before processing a request, we may reasonably verify the identity of the applicant.

You also have the right to lodge a complaint with the Czech Office for Personal Data Protection if you believe that personal-data processing infringes applicable law. Information is available at uoou.gov.cz.

11. Automated decision-making

We do not use automated decision-making or profiling that by itself produces legal effects concerning the user or similarly significantly affects the user. Automated licensing checks only technically apply predetermined license rules, such as the active-device limit or Trial expiry.

12. Security

We use reasonable technical and organisational measures appropriate to the nature of the service. Licensing communication takes place over HTTPS; license keys and license tokens are not stored in readable form in the backend database but as cryptographic hashes.

13. Changes to this Notice

Each version of this Notice is published at its own versioned URL. Historical versions remain available, and for significant licensing operations the backend may record which specific version and language was presented to the user.

The current English version is also available at /en/legal/privacy/current/.
