Mantinomia uses these vendor categories to operate the service:
Data processing agreements, subprocessors, and transfer grounds must be checked and archived before new higher-risk features are enabled. Data may also be shared when the law requires it, during security incidents, rights claims, or necessary dispute handling.
Advertising is off by default and should only be shown to anonymous users when the ads flag is enabled and valid consent exists. Signed-in and premium users should be ad-free.
AI processing of user-uploaded material is opt-in. When an AI feature is used, the interface should explain which text or file is sent, which vendor is used, and whether the data may be used for training under the vendor's terms.
You may request access, rectification, deletion, restriction, data portability, objection, and withdrawal of consent. Mantinomia should normally respond within 30 days.
Send a request through the privacy request form or by email to mantinomia@gmail.com.
You have the right to complain to the Norwegian Data Protection Authority if you believe the processing violates data protection rules. The authority usually asks that you contact the business first.
Some vendors may process data outside Norway or the EEA. Such transfers should only take place with a relevant data processing agreement, standard contractual clauses, adequacy basis, or another lawful transfer basis.
