Information We Collect

We collect only the information necessary to provide our data weighting service. This includes your account details (name, email), payment information (processed securely through Stripe), and any data files you upload for weighting analysis.

Personal Information

We collect your name and email address when you create an account. This allows us to provide customer support and communicate important service updates. Note that Persimmon Systems LLC never sees or has access to your full credit card number—all payment processing is handled securely by Stripe.

Usage Data

When you upload data files for weighting, we temporarily store and process them to calculate weights and return your results. We also collect basic usage data like login times and feature usage to improve our service.

How We Use Your Information

We use your information solely to provide our data weighting service. We don't sell or share your information for marketing purposes. Your data is processed to calculate statistical weights and returned to you—that's it.

  • To provide and maintain our service
  • To process your data weighting requests
  • To communicate with you about your account
  • To improve our services
  • To comply with legal obligations

Data Security

We protect your data using industry-standard encryption and security practices. All data transmission uses HTTPS encryption, and our servers employ standard security measures to protect against unauthorized access.

Data Retention

We keep your account information (name, email) as long as your account is active. Your project files and uploaded data remain in your account until you choose to delete them. We don't automatically delete your data—we've learned that customers appreciate being able to access their projects even years later. If you want your data deleted, simply email us at support@sampleweighting.com and we'll take care of it promptly.

Your Rights

You have complete control over your data. You can update your account information anytime, download your data, or request complete deletion of your account and all associated data. Just email us—no complicated forms or waiting periods.

Cookies and Tracking

We use minimal cookies necessary to keep you logged in and remember your preferences. We don't use tracking cookies or analytics that follow you around the web. We keep it simple.

Third-Party Services

We use a few trusted third-party services to operate our business. Stripe handles payment processing and shares basic payment details with us like your city/state, card issuer, and last 4 digits, but we never see your full credit card number or billing address. We also use email service providers to send you account-related communications. We only work with reputable companies that maintain strong privacy and security standards.

Changes to This Policy

If we need to update this policy, we'll email you about any significant changes. We'll also update the "Last updated" date at the top of this page. We won't make changes that reduce your privacy protections without giving you notice and a chance to review.
