Privacy
Last updated: 2026-08-05. DeepFeather keeps a small data footprint.
What we collect
- Votes — anonymous “I replaced this” / “I want to replace this” counts per app, rate-limited by IP.
- Digest / waitlist — email address and signup source if you subscribe.
- App tips — name, URL, email, and optional note when you use /submit.
- First-party analytics — only if
POSTHOG_KEYis configured: page views and explicit product events (prompt copy, agent open, votes). Autocapture and session recording are off. No advertising pixels.
What we do not do
- No user accounts.
- We do not sell personal data.
- We do not store prompt bodies you copy from the page.
- Sponsorship checkout (when enabled later) is handled by Stripe; card data never touches our servers.
Retention
Vote counters and rate-limit rows live in Cloudflare D1. Waitlist and submission rows stay until we process or delete them. Analytics retention follows the PostHog project settings when enabled.
