CashBFF Privacy Policy
Last updated: February 13, 2026
The short version: CashBFF collects anonymous usage data to improve the extension. We track shopping behavior on specific retail sites only. We never collect personal information, full URLs, or anything that could identify you. You can opt out at any time.
What CashBFF Does
CashBFF is a browser extension that converts dollar prices on shopping websites into "hours of work" based on an hourly wage you provide. All price conversion happens locally in your browser.

Anonymous Analytics Data We Collect
If you have analytics enabled (the default), we collect the following anonymous data when you visit the shopping sites listed above:
- Install event — that the extension was installed, plus the version number
- Wage set signal — that a wage was saved (not the value, just whether it was changed from the default)
- Shopping site visits — which retail site you visited (domain only) and whether prices were converted
- Page type — whether you're on a product page, cart, checkout, or browsing (detected from URL patterns, not the full URL)
- Session end — how long you spent on a shopping site before leaving
- Cart action — that an add-to-cart or buy-now button was clicked on Amazon (not what product was added)
- Purchase detected — that an order confirmation page was reached on Amazon (not what was purchased or the amount)
- Wage bracket — your general wage range (under $15, $15–25, $25–50, $50+), not your actual wage
- Hours active — whether prices were converted to hours-of-work on the page you visited
Data We Do NOT Collect
- Your name, email, or any personal information
- Your actual hourly wage (only a general bracket is recorded)
- Full page URLs or browsing history
- Product names, titles, or descriptions
- Product IDs or ASINs
- Search queries
- Cart contents or purchase history
- What products you add to cart or purchase (only that the action occurred on Amazon)
- Any data from sites outside our tracked list
- Any data that could identify you personally
Why We Collect This Data
- Shopping site visits — to understand which sites to add price conversion support for next
- Page type & session end — to understand if CashBFF helps users make more mindful purchasing decisions
- Cart action & purchase detected — to understand if CashBFF influences purchasing decisions
- Wage bracket — to understand if the extension works differently for different income levels
- Hours active — to compare behavior when price conversion is on versus off
Anonymous Identifier
We generate a random UUID (universally unique identifier) stored locally on your device. This allows us to count unique users and understand session patterns without knowing who they are. This ID:
- Is randomly generated and not linked to any account or personal data
- Cannot be used to identify you
- Is stored only on your device
- Is deleted if you uninstall the extension
How to Opt Out
You can disable anonymous analytics at any time:
- Click the CashBFF extension icon in your browser toolbar
- Open the Settings page
- Toggle off "Anonymous analytics"
When analytics are disabled, no data is sent from your browser. The extension continues to work normally.
Where Data Is Stored
Anonymous analytics data is stored in a Supabase database. Supabase provides secure, encrypted data storage. We use insert-only permissions for the anonymous key, meaning the extension can only add new events — it cannot read, modify, or delete any data.
Third Parties
We do not sell, share, or transfer your data to any third parties. Anonymous analytics data is used solely by the CashBFF team to improve the extension.
Changes to This Policy
If we make changes to this privacy policy, we will update the "Last updated" date at the top of this page. Significant changes will be communicated through the extension update notes.
