Privacy Policy

Last updated November 5, 2026

Kagency LLC ("we") makes Katalogue. This policy explains what we collect through the app and this website. The short version: your files, searches and transcripts never leave your computer.

In the app

• Your media, searches and index: processed and stored only on your computer. We never receive them.
• Licence activation and checks (on activation, then about once a week when online): your licence key, a hashed device fingerprint (one-way hashes of your OS installation ID, hardware ID and processor model, not the identifiers themselves), your computer's name, operating system and app version. Used to enforce the one-computer licence and to let you see and move your activations.
• Free trial: the same hashed fingerprint, so a trial runs once per computer.
• Update check (can be turned off in Settings): the app version and operating system.
• Model downloads: the app downloads AI models and tools directly from their publishers (GitHub, Hugging Face, NuGet, FFmpeg build hosts). Those services see your IP address under their own privacy policies.

On this website

• Purchases are handled by Paddle.com (Merchant of Record), which processes your payment and billing details under its privacy policy. We receive your name, email, country and order details.
• Licences: we store your email, name, licence (the key itself only as a one-way hash) and activated devices.
• Reviews you submit, with the name you choose.
• Server logs (IP address, pages requested) kept up to 30 days for security. No advertising or tracking cookies; the admin area uses one strictly necessary cookie.

Why and how long

We use this data to provide and support the licence you bought (contract), to prevent fraud (legitimate interest) and to meet tax and accounting duties (legal obligation). Licence records are kept for as long as the licence exists and 7 years after a purchase for tax purposes; trial records for 2 years.

Your rights

You can ask to see, correct, export or delete your data, or object to its use, by writing to [email protected]. If you are in the EU/UK you may complain to your data-protection authority; California residents have the rights described in the CCPA. We do not sell or share personal information.
