Privacy Notice
Last updated: November 13, 2026
This is a starter privacy notice for the current test version of FlipMargin. The operator's legal name and contact email must be added before a broad commercial launch. Have this notice reviewed for the jurisdictions where you operate.
Information you provide
If you create an account, Supabase Auth processes your email address and authentication information. If you save deals while signed in, FlipMargin stores the item name, purchase cost, expected sale price, status and creation time in its Supabase database. Do not enter sensitive personal information into deal notes or item fields.
Local browser storage
When you use the tracker without signing in, deal records are stored in your browser's local storage on that device. They are not automatically synced to another device. Clearing browser data may remove them.
How information is used
Information is used to provide account sign-in, save and display your deal records, and operate the calculator and listing draft helper. The calculator and listing helper run in your browser. The current version does not use a connected AI model, marketplace account integration, advertising tracker, or payment processor.
Service providers
Website hosting is provided by Cloudflare Pages. Account authentication and database storage are provided by Supabase. These providers process data to deliver their services under their own terms and privacy policies.
Sharing and sale
FlipMargin does not currently sell personal information or share it for cross-context behavioral advertising. Data may be processed by the service providers described above or disclosed where legally required.
Retention and deletion
Cloud deal records remain in your account until deleted through the app or an account deletion process is provided. This prototype does not yet provide self-service account deletion. For a deletion request, contact the operator using the business contact details that must be added before public launch.
Security
Supabase Row Level Security is intended to restrict cloud deal records to the signed-in account owner. No online service can guarantee absolute security. Do not reuse passwords or submit sensitive information.
Children
FlipMargin is not designed for children under 13 and is not knowingly directed to them.
Changes and contact
This notice may be updated as the product changes. Before accepting public users, the operator must publish a monitored business contact email and legal business identity here.
