Privacy Policy

Effective October 7, 2026

Flip Check (“the app,” “we,” “us”) is operated by Jacob Dattage. This policy explains what information the app collects, how it is used, and the choices you have. If you have questions, email flipcheck.help@gmail.com.

Information we collect

• Account information (optional): you can use Flip Check without an account. If you choose to create one, we store your email address and a password (kept securely by our authentication provider; we never see your password in plain text), or your Sign in with Apple identity.
• Settings you enter: sales-tax rate, ZIP code (used only to estimate shipping costs), profit thresholds, and the marketplaces you sell on.
• Items you check: barcodes you scan or products you search for, the store price you enter, the results shown, whether you marked an item as bought, and listing drafts you create.
• Your acceptance of our disclaimer: which version you accepted and when.
• Usage counts: how many lookups you make each day, used to prevent abuse and to apply plan limits.
• Subscription status: whether you have an active subscription. Payments are handled entirely by Apple; we never receive your card details.
• Camera and photos: barcode scanning happens entirely on your device. If you use Photo ID, the photo you take or choose is sent once to our server and to Anthropic’s Claude AI to identify the product, and is then discarded. We do not store your photos.

If you choose to connect a marketplace account (such as Amazon or eBay) in the future, we will store an access token that marketplace issues to us so we can show your own fees, approval status, or create draft listings. We never receive your marketplace password, and you can disconnect at any time.

How we use information

• To provide the app’s features: price lookups, profit estimates, verdicts, scan history, and listing drafts.
• To keep your account secure, prevent abuse, and enforce usage limits.
• To provide customer support when you contact us.

We do not sell your personal information, use it for advertising, or track you across other companies’ apps or websites.

Who we share information with

We share only what is needed to run the app, with these service providers:

• Supabase: hosting, database, and sign-in.
• Amazon, eBay, and other marketplaces: barcodes and product searches are sent to their official data services to retrieve prices and product details. Your name and email are not sent.
• Anthropic: product details (such as name, brand, and price range) are sent to Anthropic’s Claude AI to write listing drafts, and Photo ID pictures are sent to identify products. Your name and email are not sent.
• Apple: processes subscription purchases.

We may also disclose information if required by law or to protect the rights, safety, or property of users or others.

Data retention and deletion

We keep your information while your account is active. You can delete your account and all associated data at any time in the app under Settings → Delete my account and data, or by emailing us. Deletion is permanent. Product price lookups are cached for up to 24 hours without any personal information attached.

Security

Data is encrypted in transit (HTTPS). Access to stored data is restricted, and secret keys for marketplace and AI services are kept on our servers, never in the app.

Children

Flip Check is intended for adults who buy and resell products. It is not directed to children under 13, and we do not knowingly collect information from them.

Your rights

Depending on where you live, you may have the right to access, correct, or delete your personal information. Contact us at flipcheck.help@gmail.com and we will respond within 30 days.

Changes to this policy

If we make material changes, we will update the effective date above and, when appropriate, notify you in the app.
