1. Scope of service

AI Tools provides tools for documents, creative work, images, audio and video, learning, daily life and business. AI output may be incomplete or inaccurate; verify it yourself before publishing, signing, paying, making health decisions or other important decisions.

2. Account and security

Use the service through an account you are authorized to use, and keep your devices and sign-in status secure. If you notice unusual activity, sign out promptly and report it through the in-product help entry.

3. Lawful use

Do not use the service to infringe others’ intellectual property, privacy or other lawful rights, generate or spread illegal content, bypass quotas, authentication, risk controls or security limits, or disrupt the service through automation.

4. Your content

Using the service does not transfer your rights in the content you submit. You grant us permission to process that content to the extent necessary to provide the features you choose, and you confirm you have the right to submit it.

5. Paid services

Plan prices, periods and benefits are as shown by the server on the payment page. A payment is successful once the payment channel’s server notification is received. When a membership expires, any unused quota granted by the subscription is cleared; reward quota from check-ins, invitations and similar activities is not affected. See Payments & Refunds for refunds and subscriptions.

6. Changes and liability

We keep maintaining the service and may adjust, suspend or retire some features when necessary, giving notice in advance where possible. Impacts caused by force majeure, third-party service failures or user violations are handled under applicable law.

7. Updates to these terms

Significant changes are announced in the product or on the website. You can review the updated terms before continuing; if you disagree, you can stop using the service and request account deletion.
