We are Shopify App Developers and have created a few apps which are under https://apps.shopify.com/partners/webomnific
Each app contains the contact form. If you contact us through this form, an email is sent to us. We don’t store this data anywhere else other than the email we have received.
Merchants: On the 8th day after uninstallation, we don’t have any information in our database that you have used our app.
Customers of Merchants: On the 8th day, we don’t have any information about the customers using apps through merchants. We delete all logs and database entries regularly.
