Refunds are not provided for partial billing periods.

5. AI-generated content

Corrections, coaching feedback, and progress scores are generated by artificial intelligence. While we strive for accuracy, AI-generated content may contain errors or inaccuracies. Bonjournal's feedback should be used as a learning aid and is not a substitute for professional language instruction. We make no guarantees about the accuracy or completeness of AI-generated corrections.

You retain full ownership of the journal entries you write on Bonjournal. By submitting content, you grant us a limited license to process your text through our AI systems solely for the purpose of providing the service (generating corrections and feedback). We do not share, sell, or use your journal content for any other purpose.

Bonjournal is provided "as is" without warranties of any kind, either express or implied. To the fullest extent permitted by law, we shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, use, or profits, arising out of or related to your use of the service.

8. Termination

We may suspend or terminate your access to Bonjournal at any time for conduct that we determine violates these Terms of Service or is harmful to other users, us, or third parties. You may delete your account at any time by contacting us at hello@bonjournal.app.

9. Changes to these terms

We may update these Terms of Service from time to time. If we make significant changes, we will notify you via email or through a notice on the service. Your continued use of Bonjournal after changes are posted constitutes your acceptance of the updated terms.
