Privacy Policy
Last updated: July 5, 2026
Who we are
Empire Signal is built by a solo independent developer. For any privacy request, contact cesarabrahamhernandezponce@gmail.com.
What we collect
If you create an account, we store your email and password through Supabase Auth. When you use the app, we keep the words and any optional context you submit for analysis. We also collect anonymized usage analytics to understand how the app is used.
Analytics
We use PostHog for analytics, including session replay — recordings of how you interact with the interface. This lets a solo developer find and fix bugs without a dedicated QA team.
AI processing
Word analyses are generated by third-party AI providers (Google Gemini and models via OpenRouter). On their free tiers, the text you submit may be used by those providers to improve their models. Please do not include personal or sensitive information in the word or context fields.
Caching
Word analyses are stored in a shared global cache so that other users benefit from work already done. Your personal search history stays private to your account.
Data deletion
You can delete your search history from within the app at any time. To delete your account entirely, send a request to cesarabrahamhernandezponce@gmail.com.
Cookies
We only use functional cookies: those needed to keep you signed in (Supabase authentication sessions) and those used by our analytics.
