Privacy Policy
Last updated · July 2026
This is a starting template, not legal advice — have it reviewed before launch.
This policy explains what data Faby handles and how. Faby is a Windows app that corrects your text inside any application.
What we collect
Account: your email and first name, managed by our authentication provider.
Payment: handled by Stripe. We never see or store your card details.
Usage: we count the volume of corrections (as token totals) to run fair-use limits — never the content of your text.
Your text stays yours
When you trigger a correction, the selected text is sent securely to our backend and to our AI provider solely to produce the correction. It is not stored, and it is never used to train any model.
Service providers
We rely on Supabase (authentication & database), Railway (backend hosting), Stripe (payments) and Anthropic (AI correction). Each processes data only to provide its part of the service.
On your device
Your login session is stored locally on your device, encrypted with Windows DPAPI. Your preferences are saved locally too.
Your rights
You can access or delete your account data at any time by contacting us. We keep account data only while your account exists.
