Acceptable use policy

This acceptable use policy governs how customers may use BookNLink modules, API access and the workspace. Breach of this policy may result in suspension of the affected module and, in serious cases, termination of the underlying contract for cause.

1. Prohibited use

• Reverse engineering, decompiling or attempting to derive the source code of any module beyond what is permitted under mandatory copyright exceptions.
• Circumventing the rate limits, authentication or authorisation controls of the BookNLink API through any means.
• Using the modules to distribute or store content that is illegal under German or EU law, including but not limited to content that infringes third-party intellectual property rights.
• Sending unsolicited commercial messages to guests captured through the modules, unless a valid legal basis under GDPR is documented in the workspace.
• Using the modules to inflate or falsify reviews on any distribution platform.
• Sharing API credentials with third parties outside the customer's organisation without a written data-processing agreement.

2. Fair use of API calls

Each module has a fair-use quota specified in the module description. Sustained exceedance of the quota by more than 25% for three consecutive days triggers a fair-use notice. If no engineering-level explanation is provided within seven days, the module may be throttled to the quota until the situation is resolved.

3. Security

Customers must safeguard their workspace credentials, enforce two-factor authentication for all users, and notify us of any suspected compromise within 24 hours. Security researchers may report vulnerabilities in good faith to security@booknlink.org; we follow a coordinated disclosure practice with response within 72 hours.

4. Reporting abuse

Reports of abuse (spam, fraud, prohibited use) should be sent to abuse@booknlink.org. All reports are triaged within one business day.

5. Enforcement

Suspected breaches are investigated by our compliance team. Where a breach is confirmed, we apply the following remediation ladder: notice, throttle, temporary suspension, termination for cause. Each step is documented in the customer's workspace journal.
