Sale and Sharing of Personal Information

Celtek does not intend to sell customer personal information for monetary consideration.

Depending on applicable privacy law, certain uses of advertising or analytics technologies may sometimes be legally defined as “selling” or “sharing” personal information even when no money changes hands.

If Celtek engages in activity considered a sale or sharing under applicable privacy law, eligible individuals may exercise the rights provided under that law.

We may update this Privacy Policy if our practices materially change.

Data Retention

We retain personal information for as long as reasonably necessary for the purpose for which it was collected and for legitimate business or legal requirements.

• Legal claims
• Security considerations

We aim to avoid retaining personal information that we no longer reasonably need.

Data Security

Celtek uses reasonable administrative, technical, and organizational measures intended to protect personal information against unauthorized access, disclosure, alteration, or loss.

No internet transmission or electronic storage system can be guaranteed to be completely secure.

Customers should protect their account credentials and notify Celtek if they believe an account has been compromised.
