Privacy Policy
Last updated: June 6, 2026
ProfitLens ("we", "us") operates profitlens.cybersquarekw.com and the ProfitLens Chrome extension. This policy explains what data we collect and how we use it.
What we collect
- Calculator inputs — sale price, COGS, fees, and scenarios you enter. Stored locally in your browser (localStorage) unless you share a URL.
- Chrome extension — default COGS, shipping, daily overlay quota, and Pro license token in Chrome sync storage. Listing prices are read from the page you visit to compute margin; we do not send listing data to our servers.
- Analytics — anonymous page views, checkout clicks, and feature usage (hashed session ID, no name or email). Used to improve the product.
- Email waitlist — if you opt in, your email is synced to Formspree (our form provider) and stored locally in your browser.
- Pro checkout — payment and email handled by Lemon Squeezy; we receive license verification via webhook, not card details.
What we do not collect
- Marketplace account credentials or OAuth tokens
- Order history from Etsy, Amazon, eBay, Poshmark, Depop, or Mercari
- Cross-site browsing history outside supported listing pages
- Sale of personal data to third parties
Extension permissions
The Chrome extension requests storage and host access to supported marketplace domains plus profitlens.cybersquarekw.com (license sync). Content scripts run only on listing pages you open — not in the background on unrelated sites.
Third parties
- Lemon Squeezy — payment processing and subscription management
- Formspree — email waitlist and margin alert digest (when enabled)
- Shopify Affiliate — optional affiliate links; click tracked in our analytics
Data retention
Local browser data persists until you clear site data or uninstall the extension. Analytics events are aggregated on our server; raw events rotate with dashboard exports.
Your choices
- Clear localStorage / extension storage anytime
- Use the calculator without creating an account
- Opt out of analytics by blocking requests to our analytics endpoint
