1. Intended Use

Trefnus Resource is licensed for legitimate internal scheduling and booking of resources for which you, your organisation or your client has lawful authority. Any use that goes beyond that purpose, that is unlawful, or that infringes the rights of others, is strictly prohibited.

• remove, alter or obscure any proprietary notice, copyright marking or licence verification indicator;
• encourage, induce, assist or enable any third party to do any of the above.

3. Account Responsibilities

You are solely responsible for all activity that takes place under your account or on any Device on which the Application is activated, whether or not authorised by you. You must keep your magic-link emails, your local Application password and your Device secure. You must notify us promptly at security@trefnus.com of any actual or suspected unauthorised access or compromise.

4. Device Usage

You may activate the Application on up to five (5) Devices per licensed account. You agree that:

• each Device must be under your personal control, or under the control of an individual member of your organisation acting on your behalf;
• you must not share your magic-link email with any unauthorised person;
• you must not use scripts, virtualisation, container snapshots or other techniques designed to defeat or extend the device limit;
• when you cease using a Device (e.g. selling, replacing, returning to an employer), you must remove it from the device list via the Settings > Devices screen, and clear local Application data on that Device.

5. Data Responsibility

You are solely responsible for the data you enter, store and process in the Application, including:

• ensuring you have all rights and permissions necessary to enter and process that data;
• complying with applicable data-protection law in respect of any personal data of third parties (guests, customers, employees, contractors);
• taking regular exports/backups of your data and storing those backups securely;
• ensuring that any device on which the Application is used is itself secured against unauthorised access.

6. Reporting Violations

If you become aware of any actual or suspected breach of this AUP, please report it to abuse@trefnus.com with as much detail as you can provide. We treat such reports confidentially where reasonably possible.

7. Enforcement

We may, at our sole discretion and without liability to you or any third party, take any or all of the following actions in response to an actual or suspected breach of this AUP:

• issue a warning;
• require you to remove or stop processing specific data;
• limit, suspend or terminate your access to the Application;
• revoke your licence in whole or in part, immediately and without refund;
• remove individual Devices from your account;
• cooperate with law enforcement, regulators or other lawful authorities;
• pursue any remedy available to us at law or in equity, including injunctive relief and damages.

8. Monitoring

We do not monitor the Content you store in the Application (which is stored only on your Device and is not visible to us in normal use). We may, however, monitor server-side activity associated with licence verification, magic-link issuance and device registration to detect abuse, fraud, security incidents and breaches of this AUP. We may use the results of such monitoring for any lawful purpose, including enforcement of this AUP.

9. Changes

We may update this AUP from time to time. The updated AUP will be posted at /legal/acceptable-use-policy.html with a new effective date. Your continued use of the Application after the effective date constitutes acceptance of the updated AUP.
