The agreement, stated plainly.
These terms govern your use of TwentyThird. They are written to be read, not avoided.
The service
TwentyThird is a psychodynamic AI service operated by WelloWork AB. Readings, replies and reports are written by AI models from what you share, and they can be wrong. It is not a medical device and it is not psychotherapy, diagnosis or treatment. If you are in distress, contact a clinician; in an emergency, call your local emergency number.
Your account
You must be 18 or older to use TwentyThird. You are responsible for maintaining the confidentiality of your credentials. You may not share your account or use the platform on behalf of another person without their explicit consent.
You own what you write. By submitting it you allow WelloWork AB to process it as the Privacy Policy describes. You can export or delete your content at any time in Settings.
Acceptable use
You may use TwentyThird for lawful personal and professional self-exploration. You may not use it to harm yourself or others, to attempt to circumvent the platform's safety systems, to reverse-engineer the underlying models, or to train competing AI systems.
We reserve the right to suspend or terminate accounts that violate these terms, without prior notice where required for safety.
Our liability
TwentyThird provides insight, not certainty. We do not warrant that the analysis is accurate, complete, or appropriate for your circumstances. To the extent permitted by Swedish law, our liability is limited to the amount you paid in the 3 months preceding the relevant claim.
Nothing in these terms limits liability for death or personal injury caused by our negligence, or for fraud.
Governing law and disputes
These terms are governed by Swedish law. Disputes that cannot be resolved directly are referred to the courts of Uppsala, Sweden, as the court of first instance.
If you are a consumer in the EU, you also have access to the EU Online Dispute Resolution platform at ec.europa.eu/consumers/odr.
Changes
We may update these terms. Material changes are announced in the product before they apply, and we ask you to accept them again where needed.
