Privacy Policy
Effective Date: December 10, 2025
Introduction
Welcome to Vine Gremlin, a product of WhistleStack. This Privacy Policy explains how we collect, use, and protect your personal information when you use our inventory tracking service. We are committed to protecting your privacy and being transparent about our data practices.
Our Commitment to Your Privacy
We never share or sell your personal information.
At Vine Gremlin, we believe that selling personal information is a disgusting and reprehensible behavior. We firmly stand against the commodification of user data that has become all too common in today’s digital landscape.
We believe that consent should never be tied to a person’s ability to use a product or service. You should never have to trade your privacy for functionality. Your data belongs to you, not to advertisers, data brokers, or third parties.
At Vine Gremlin, we will never willingly or knowingly provide your information to anyone.
All information obtained is solely for the usage of your account and the operation of our service. Period.
Information We Collect
Account Information
When you create an account, we collect your name, email address, and password (stored securely using industry-standard encryption). This information is necessary to provide you with access to your account and our services.
Inventory Data
We store the inventory information you enter into our system, including item names, ASINs, estimated tax values (ETV), dates received, sale prices, marketplace information, and any notes you add. This data is essential for providing our inventory tracking service.
Payment Information
If you subscribe to our paid service, payment processing is handled securely by Stripe. We do not store your complete credit card information on our servers. Stripe’s privacy practices are governed by their own privacy policy.

That’s it. We do not use your information for advertising, profiling, or any purpose beyond providing you with the service you signed up for.
What We Will Never Do
To be absolutely clear, we will never:
- Sell your personal information to anyone, for any reason
- Share your data with advertisers or marketing companies
- Provide your information to data brokers
- Use your data to build profiles for third parties
- Track you across other websites or services

Data Retention
We retain your personal information only for as long as necessary to provide our services to you. If you choose to delete your account, we will delete your personal data from our active systems. Some information may be retained in backups for a limited period as required for legitimate business purposes or legal compliance.

Legal Disclosure
While we will never willingly share your information, we may be required to disclose personal information if compelled by law, such as in response to a valid court order or subpoena. In such cases, we will provide only the minimum information legally required and will notify you if permitted by law.
