Privacy Policy
Last updated: March 14, 2026
1. Introduction
Flip Engine X ("we," "us," or "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, store, and protect your personal information when you use our progressive web application and website at flipenginex.com.
2. Information We Collect
Account Information
- Email address (required for account creation)
- Name (if provided)
- Authentication data (hashed passwords, OAuth tokens for Google sign-in)
Subscription & Payment Data
- Subscription tier and billing cycle
- Payment information is processed securely by Square — we never store your full credit card number, CVV, or other sensitive payment details on our servers.
- Square customer ID and subscription ID for managing your account
Usage Data
- Scan history and scan logs (barcodes scanned, timestamps)
- Product lookup results and saved records
- Trigger configurations and batch data
- App settings and preferences
Amazon Seller Data (SP-API)
- If you connect your Amazon Seller Central account, we access inventory, pricing, and gating data through Amazon's SP-API. This data is used solely to provide Service functionality and is not shared with third parties.
Device & Technical Data
- Browser type and version
- Device type (mobile, desktop)
- IP address (for security and abuse prevention)
3. How We Use Your Information
- Provide, maintain, and improve the Service
- Process subscriptions and payments
- Sync your data across devices (scan history, triggers, batches, settings)
- Enforce scan limits and subscription tier restrictions
- Send transactional emails (account verification, password resets, billing receipts)
- Respond to support requests
- Detect and prevent fraud or abuse
4. Data Storage & Security
Your data is stored securely using industry-standard practices:
- Database: All user data is stored in Supabase (hosted on AWS) with row-level security (RLS) policies ensuring users can only access their own data.
- Authentication: Passwords are hashed using bcrypt. We support OAuth (Google) and magic link authentication through Supabase Auth.
- Payments: All payment processing is handled by Square. Card data is tokenized client-side using Square's Web Payments SDK — sensitive payment information never touches our servers.
- Encryption: All data in transit is encrypted via TLS/HTTPS. Data at rest is encrypted by our infrastructure providers.
- Access Control: API endpoints are protected by authentication middleware. Database access is restricted by row-level security policies.
5. Data Sharing
We do not sell, rent, or trade your personal information. We share data only with:
- Supabase: Database hosting and authentication (data processor)
- Square: Payment processing
- Keepa: Product data lookups (only barcode/ASIN data is sent — no personal information)
- Amazon SP-API: Only when you explicitly connect your Seller Central account
- Vercel: Application hosting
We may disclose information if required by law, court order, or to protect the rights, property, or safety of our users or the public.
6. Data Retention
- Account data is retained for as long as your account is active.
- Scan logs and usage data are retained for up to 12 months after your last activity.
- Upon account deletion, all personal data is permanently removed within 30 days.
- Payment records may be retained as required by financial regulations.
7. Your Rights
You have the right to:
- Access your personal data stored by the Service
- Correct inaccurate or incomplete data
- Delete your account and all associated data
- Export your data in a portable format
- Disconnect third-party integrations (Amazon SP-API) at any time
To exercise any of these rights, contact us at info@flipenginex.com.
8. Cookies & Local Storage
The Service uses browser local storage and cookies for authentication tokens, user preferences, and offline functionality (PWA). We do not use third-party tracking cookies or advertising trackers.
9. Children's Privacy
The Service is not intended for users under the age of 18. We do not knowingly collect personal information from minors. If we learn that we have collected data from a user under 18, we will promptly delete that information.
10. Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of material changes via email or through the Service. The "Last updated" date at the top of this page reflects the most recent revision.
