Data Retention Policy
Last Updated: April 22, 2026
Introduction
This Data Retention Policy explains how Qardnel retains, stores, and deletes personal data and other information collected through our educational platform. We are committed to retaining your data only as long as necessary to fulfill the purposes outlined in our Privacy Policy and to comply with legal obligations.
Scope
This policy applies to all data collected by Qardnel through our website, online courses, communications, and related services. It covers personal data of students, instructors, visitors, and any other individuals who interact with our platform.
Data Categories and Retention Periods
Account Information
Personal data associated with user accounts, including names, email addresses, and profile information, is retained for the duration of the active account plus three years following account closure or last activity. This allows us to respond to inquiries, resolve disputes, and maintain educational records.
Course Enrollment and Progress Data
Information related to course enrollments, completion status, grades, certificates, and learning progress is retained for seven years after course completion. This extended period supports credential verification, transcript requests, and educational record maintenance.
Payment and Transaction Records
Financial transaction data, including payment method details and purchase history, is retained for seven years from the date of the transaction to comply with accounting requirements, tax obligations, and to resolve billing disputes.
Communications and Support Records
Email correspondence, support tickets, chat logs, and other communications are retained for three years from the date of the last interaction. This enables us to provide consistent support and maintain service quality.
Usage and Analytics Data
Technical data such as IP addresses, device information, browser types, and platform usage patterns are retained for two years. Aggregated and anonymized analytics may be retained indefinitely for research and service improvement purposes.
Marketing and Promotional Data
Contact information and preferences related to marketing communications are retained until you withdraw consent or unsubscribe, plus six months to ensure proper processing of your request and to honor your preferences.
Cookies and Tracking Technologies
Data collected through cookies and similar technologies is retained according to the specific retention periods set for each cookie type, typically ranging from session duration to two years, as described in our Cookie Policy.
Legal and Regulatory Retention
In certain circumstances, we may be required to retain data for longer periods to comply with legal obligations, regulatory requirements, or court orders. When legal retention obligations apply, we will retain the relevant data for the required period, even if it exceeds our standard retention schedule.
Data Deletion and Anonymization
Automated Deletion
We employ automated systems to identify and delete data that has exceeded its retention period. These systems run regular reviews to ensure timely deletion in accordance with this policy.
Anonymization
Where possible, we anonymize personal data rather than deleting it entirely. Anonymized data cannot be linked back to individual users and may be retained indefinitely for statistical analysis, research, and service improvement.
Secure Deletion Methods
When data is deleted, we use secure deletion methods to ensure it cannot be recovered or reconstructed. This includes overwriting data, degaussing storage media, and physical destruction of hardware when appropriate.
User Rights and Data Deletion Requests
You have the right to request deletion of your personal data at any time. Upon receiving a verified deletion request, we will delete your data within 30 days, except where retention is required by law or necessary to resolve disputes, enforce agreements, or protect our rights.
To request deletion of your data, please contact us at info@qardnel.com. We will confirm receipt of your request and notify you once the deletion is complete.
Exceptions to Deletion
We may retain certain data beyond the standard retention periods in the following circumstances:
Ongoing Transactions: Data related to incomplete transactions or active disputes will be retained until resolution.
Legal Claims: Data relevant to pending or threatened legal proceedings will be retained until the matter is fully resolved.
Security and Fraud Prevention: Information necessary to detect, prevent, or investigate security incidents or fraudulent activity may be retained as long as reasonably necessary.
Backup Systems: Data may persist in backup systems for up to 90 days after deletion from active systems. Backup data is not accessible for normal operations and is deleted according to our backup rotation schedule.
Data Retention Review
We regularly review our data retention practices to ensure they remain appropriate, necessary, and compliant with applicable laws. This policy is reviewed at least annually and updated as needed to reflect changes in our services, legal requirements, or industry best practices.
Third-Party Service Providers
When we share data with third-party service providers, we require them to adhere to retention periods consistent with this policy or to delete data when it is no longer needed for the specified purpose. We maintain agreements with service providers that define retention obligations and deletion procedures.
Changes to This Policy
We may update this Data Retention Policy from time to time. When we make material changes, we will notify you by updating the "Last Updated" date at the top of this policy and, where appropriate, provide additional notice through our platform or via email.
