Also identify any privacy practices mentioned: You may review, change, update, correct or delete the Personal Information by contacting us at privacidade@psafe.com. You authorize us to use and disclose any new or modified information that you provide in accordance with this Privacy Policy, and you agree that we are under no obligation to delete or modify information that you have previously chosen to provide us. We may also retain an archived copy of your records as required by law or for legitimate business purposes.

Certain information is necessary in order for us to provide the services; therefore, if you delete such necessary information you may not be able to use the services. Please note that even though you may request the deletion of your Personal Information by us, we may be required (by law or otherwise, such as to prevent fraud, resolve disputes, troubleshoot problems, or enforce our Terms of Use and/or Privacy Policy) to keep this information and not delete it (or to keep this information for a certain time) in which case we will comply with your deletion request only after we have fulfilled such requirements. When we delete Personal Information, it will be deleted from the active database, but may remain in our archives."}, {'role': 'assistant', 'content': 'This clause is fair.
