Security

Your data stays yours.Safe by design.

Fermium100 works with your App Store data and keys. Here is exactly how we keep them safe, in plain words.

Keys stored encryptedYour App Store Connect, Apple Ads and RevenueCat keys go into an encrypted vault (Supabase Vault), not into normal tables.
Servers in LondonOur database runs in London, our app servers right next to it. Your data doesn't travel around the world.
Every workspace walled offRow-level security in the database: a workspace can only ever read its own apps, keywords and numbers.
AI links you controlYour link for Claude or ChatGPT is shown once. We only keep a fingerprint of it (SHA-256), and you can revoke it any time.
No card data with usPayments run through Stripe. We never see or store your card number.
Safe sign-inSign in with email, Apple or Google. We never see your Apple or Google password.
No ad trackersOur website counts visits without cookies. Google Analytics only runs if you say yes. We never sell data.
You stay in controlDisconnect a service in Settings and its stored key is deleted right away. Want everything gone? Email us.
