1. Scope
These Terms govern the agreement between Mindex UG (haftungsbeschränkt) ("Mindex") and individuals or organisations ("Users") for the use of our web app, mobile clients, and APIs.

2. Account creation

• The agreement starts once you complete registration and confirm your email.
• Users must be at least 16 years old and provide accurate information.
• Accounts are non-transferable and credentials must remain confidential.
• Mindex may decline registrations for legitimate reasons.

3. Services
Mindex offers a cloud platform for bookmarking, knowledge organisation, and AI-assisted link categorisation. Features and limits follow the plan description (Free, Pro, Enterprise). Beta functionality may change or be discontinued.

4. Fees & payment
Paid plans are billed in advance on a monthly or annual basis via the designated payment provider. Prices include statutory VAT unless stated otherwise. Invoices are provided electronically. Access may be suspended after prior notice if payments are overdue.

5. Term & termination

• Free tiers run indefinitely and can be cancelled anytime.
• Subscriptions renew automatically unless cancelled at least one day before the end of the term.
• Cancellations can be submitted via the account area or in writing.
• Both parties may terminate for cause (e.g., non-payment, abuse, legal violations).

6. Content rights
Users retain ownership of their content and grant Mindex a non-exclusive, geographically limited licence to provide the services. Only upload content you have sufficient rights to and respect applicable law and third-party rights.

7. Acceptable use
It is forbidden to distribute malware, spam, unlawful or discriminatory content, or to circumvent security controls. Mindex may remove content, suspend, or delete accounts and notify authorities if violations occur.

8. Availability & maintenance
We target 99% monthly availability. Planned maintenance windows are announced in advance. In case of outages, Mindex will take reasonable steps to restore service.

9. Warranty & liability
Mindex is fully liable for intent, gross negligence, and damages to life, body, or health. For simple negligence we only cover essential contractual duties and limit compensation to foreseeable damages. Product liability remains unaffected.

10. Changes to these Terms
We may amend these Terms for valid reasons (legal changes, feature updates). We will notify you at least 30 days in advance. Continued use without objection constitutes acceptance. If you object, Mindex may terminate the agreement with 30 days’ notice.

11. Governing law
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a merchant, the place of jurisdiction is Berlin. Mandatory consumer protections remain untouched.
