Privacy policy
Last updated: 2026-05-20
What we collect
- Recipient context you choose to share — the LinkedIn URL or about text you paste into Coldsage. Sent to Anthropic via our backend Worker to generate openers. NOT logged on our side.
- Subscription identity — an ExtensionPay api_key (anonymous; stored in your browser's chrome.storage.sync). Used only to verify you're a paid subscriber.
- Anonymous crash reports — when the extension hits an unhandled error, a per-install random clientId (NOT a user identifier) and the error message + stack are sent to our Worker. Rate-limited to 5 reports per 5 minutes per install.
What we don't collect
- Your email address (unless you contact us via hello@coldsage.dev)
- The contents of emails you send (we only see what you actively submit via the popup; the full message body is never read)
- Your browsing history, location, or web activity
- Recipient lists, contact databases, or any prospect data you haven't actively submitted to the popup
- The text of openers you generate (these live in your browser only; we never log request bodies on our side)
Third parties
- Anthropic — receives recipient context you submit, to generate openers. Their privacy policy.
- ExtensionPay + Stripe — receives payment information if you subscribe. We never see card details. ExtensionPay's privacy policy.
- Cloudflare — hosts our Worker backend. Standard request logs (IP, user-agent) per Cloudflare's policy.
