User data deletion

Users have the authority to manage, use and delete data generated by the platform, and the following is a clear explanation of data deletion:
Scope of data that can be deleted:
1. Projects created by users and basic project information; when there are products that have been released for mass production, the corresponding projects do not provide deletion operations.
2. Products created by users and the basic information of the products, including but not limited to: function definition, interface style, alarm configuration, and distribution network guidance graphic. The published products do not provide deletion operation, but do not include the configuration information related to human-computer interaction, such as alarm configuration, interface style and network guidance.
3. Configuration information associated with APP and products.
4. The service operation log record information generated by user operation does not provide deletion operation capability, and the retention period is up to 30 days.
Description of deletion mechanism:
1. The deletion mode of project information, product information and product-associated configuration information adopts the logical deletion method, i.e. the original data records will be retained in the database after the deletion operation. The current retention period is long-term.
