Hlas / Privacy

Privacy

Hlas has two layers: local mode, where audio never leaves your computer, and Hlas Cloud, where audio is transcribed by Groq and stored nowhere. This is a plain-language summary; the full policy and terms are being prepared with a lawyer.

What does Hlas send from my computer in local mode?

Nothing. Transcription runs through whisper.cpp on your computer, with no account and no telemetry. The only network actions are the one-time model download and the Sparkle update check, which the app asks about once.

What happens with my own API key?

Audio goes straight to the provider you picked (Groq, OpenAI, Soniox or Fish Audio) under their terms. The key is stored in the system keychain and never passes through our servers.

What happens with Hlas Cloud?

Audio goes from the app through our server on Cloudflare to Groq, which transcribes it and returns the text. Our server stores neither the audio nor the text. We only keep what the subscription needs: the Stripe customer ID, your email, an encrypted licence key and the seconds of audio per day for fair use.

Do you track visitors?

Only anonymously. When you click download or subscribe on the website, the server adds one to a counter for that button and the page language. We store no IP address, no cookie and no identifier. For the Hlas Cloud trial the app creates a random install ID so a trial can start only once; we keep only a hash of it. The same hash enforces the limit of 5 computers per subscription.

Who processes the data?

The controller is Eden Makers s.r.o., company ID 24518344, Plzeňská 3352/156, 150 00 Prague, Czech Republic. Processors are Stripe (payments and invoices), Cloudflare (server and database) and Groq (audio transcription in Hlas Cloud).

Does the website use cookies?

No. The site uses no cookie-based analytics or tracking scripts. The Stripe checkout page has its own terms.
