All service providers are contractually bound to protect your data, use it only for specified purposes, and maintain security standards at least as protective as those described in this Policy.
To route Orders on your behalf, Kessel transmits necessary Order parameters to Polymarket, Kalshi, and other venues you have connected. This includes Order size, price, direction, and routing instructions. Kessel transmits only what is required to execute your instructions. Your credentials are transmitted directly to the applicable venue and are not stored in plaintext.

Where legally permitted, we will notify you before disclosing your information in response to legal process.
If Kessel is acquired, merges with another entity, or undergoes a change of control or bankruptcy proceeding, your information may be transferred to the successor entity as part of that transaction. The successor will be required to honor this Privacy Policy or obtain your consent to material changes.
We may share information in ways not described in this Policy if you explicitly authorize us to do so.
We implement industry-standard security measures, including:
You are responsible for:
No system is 100% secure. Kessel cannot guarantee absolute security and is not liable for unauthorized access resulting from your failure to secure credentials or from events outside our reasonable control.
We retain account information and API usage logs for the duration of your account and for a period of 3 years following account termination, unless a longer retention period is required by applicable law.
Order logs, fill records, routing policy configurations, and execution quality metrics are retained for 5 years following the date of the relevant activity. This retention period reflects potential regulatory inquiry windows applicable to trading activity.
Transaction records and billing history are retained for 7 years to satisfy tax and financial recordkeeping requirements.
System logs and error logs are retained for 90 days unless needed for an active security investigation or legal proceeding.
Aggregated, de-identified usage and performance data may be retained indefinitely as it cannot be re-associated with any individual user.
Upon account termination, your active access is immediately revoked. We will delete or anonymize personal data within 30 days of termination, subject to the retention periods described above and any legal obligations requiring longer retention. You may request deletion of specific data by contacting team@kesselgateway.com.
You may request a copy of the personal data Kessel holds about you. We will provide it in a machine-readable format (JSON or CSV) within 30 days of a verified request.
You may request correction of inaccurate or incomplete personal data in your account. You can update most account information directly through your account settings.
You may request deletion of your personal data. We will honor deletion requests subject to legal retention obligations described in Section 5. Some data (execution records, billing records) cannot be deleted during applicable retention periods.
We do not send marketing communications by default. If you receive any, you may opt out at any time by clicking "unsubscribe" or emailing team@kesselgateway.com.
