Data Retention Policy
Last updated: April 4, 2026
This Data Retention Policy describes how Weknusa collects, stores, and deletes personal data and other information in connection with the services provided through weknusa.com. This policy applies to all users, participants, and visitors of the platform.
1. Purpose
Weknusa retains data only for as long as necessary to fulfill the purposes for which it was collected, to comply with applicable legal obligations, resolve disputes, and enforce agreements. When data is no longer needed, it is securely deleted or anonymized.
2. Types of Data Collected
The platform may collect and retain the following categories of data:
- Account and registration data — name, email address, contact details, and credentials provided during sign-up
- Usage and activity data — records of interactions with course materials, assignments, exercises, and collaborative tools
- Communication data — messages, feedback submissions, and support correspondence
- Payment and billing data — transaction records, invoices, and related financial information
- Technical data — IP addresses, browser type, device identifiers, and session logs
3. Retention Periods
Retention periods are determined based on the category of data and the purpose for which it is held. The table below outlines standard retention durations:
| Data Category | Retention Period | Basis for Retention |
|---|---|---|
| Account and registration data | Duration of account plus 2 years after closure | Service delivery, legal obligation |
| Course progress and activity records | Duration of account plus 1 year after closure | Service delivery, user access to history |
| Communication and support records | 3 years from last interaction | Dispute resolution, service improvement |
| Payment and billing records | 7 years from transaction date | Financial and legal compliance |
| Technical and log data | 90 days from collection | Security monitoring, fraud prevention |
| Marketing preferences | Until consent is withdrawn or account is closed | Consent-based processing |
These periods represent standard practice and may be extended where required by law, ongoing legal proceedings, or legitimate business necessity.
4. Criteria Used to Determine Retention Periods
When establishing retention periods not explicitly listed above, Weknusa considers the following criteria:
- The nature and sensitivity of the data
- The potential risk of harm from unauthorized use or disclosure
- The purposes for which the data was collected and whether those purposes can be achieved through other means
- Applicable legal, regulatory, or contractual requirements
- Guidance from relevant supervisory authorities
5. Data Deletion and Anonymization
5.1 Deletion Process
Upon expiry of the applicable retention period, personal data is permanently deleted from active systems and backup storage in a manner that prevents reconstruction or recovery. Deletion is carried out through secure erasure methods appropriate to the storage medium involved.
5.2 Anonymization
In certain cases, rather than deleting data, Weknusa may anonymize it so that it can no longer be associated with any identifiable individual. Anonymized data may be retained indefinitely for analytical, statistical, or research purposes, as it no longer constitutes personal data.
5.3 Backup Systems
Data that has been marked for deletion may remain in encrypted backup systems for a limited period as part of standard backup rotation cycles. Such data is not accessed for operational purposes and is overwritten in accordance with the backup schedule, typically within 90 days.
6. Account Closure and Data Deletion Requests
6.1 Account Closure
When a user closes their account, personal data is scheduled for deletion in accordance with the retention periods set out in Section 3. The account becomes inactive immediately, and access to platform features is revoked. Certain data may be retained beyond account closure where required by law or for legitimate business purposes.
6.2 User-Initiated Deletion Requests
Users may request deletion of their personal data at any time by contacting Weknusa at info@weknusa.com. Requests will be reviewed and processed within a reasonable timeframe. Weknusa may retain certain data where retention is required or permitted under applicable law, and users will be informed of any such exceptions.
7. Third-Party Data Processors
Weknusa may share data with trusted third-party service providers who process data on its behalf, including hosting providers, payment processors, and communication platforms. Such processors are contractually required to retain data only for the duration necessary to perform their services and to delete data in accordance with Weknusa's instructions and applicable obligations.
8. Data Security During Retention
All retained data is protected by appropriate technical and organizational measures, including encryption at rest and in transit, access controls, and regular security assessments. Access to retained personal data is restricted to authorized personnel who require it for legitimate operational purposes.
9. Special Categories of Data
Weknusa does not intentionally collect special categories of sensitive personal data. If such data is inadvertently received, it will be deleted promptly upon identification unless a specific lawful basis for its retention exists.
10. Children's Data
The platform is not directed at children under the age of 16. Weknusa does not knowingly collect personal data from individuals in this age group. If such data is identified, it will be deleted without delay.
11. Policy Review
This policy is reviewed periodically and updated to reflect changes in legal requirements, business practices, or technological developments. The date at the top of this page indicates when the policy was last revised. Continued use of the platform following any update constitutes acceptance of the revised policy.
