Privacy

Gasbag is built so that your meetings never reach the internet. This page says exactly what stays on your Mac, what leaves it, what buying a licence records, and what this website collects.

The app

Recordings, transcripts, speaker names, titles, folders and any notes an assistant writes are stored on your Mac, in Library, Application Support, Gasbag. Transcription and speaker detection run on the Mac. No audio, transcript or title is uploaded by Gasbag, and the part of the app that can use the network is kept apart from the part that can see your recordings. This is checked by tests on every build.

Gasbag connects to two hosts, and only these:

• licence.resynthesis.com.au, every few days, to check your key. It sends the key and a name for this Mac, nothing about your recordings.
• TelemetryDeck, for anonymous usage counts such as how often a feature is used. An event holds only fixed names, numbers and yes or no flags, never content. You can switch this off in Settings, then Privacy, and nothing is sent while your library is locked.

If you connect an assistant, Claude or ChatGPT can read only the recordings or folders you have shared, and only while you leave that switch on. What the assistant does with what it reads is governed by its own provider's terms, not by Gasbag. Syncing between your own Macs runs over your own Wi-Fi, encrypted and directly. Updates come through Sparkle, signed and checked before they install, and an update request carries only the app version and your licence key.

Buying a licence

Payment is handled by Stripe. We never see your card. Our licence service keeps what it needs to issue and honour your key: your email address and the name Stripe gives us, the key itself, the Stripe reference for the purchase, a record of each Mac the key is activated on, how many times the download link has been used, and whether you asked for product news. We keep this for as long as the licence exists so that we can reissue keys and links and honour updates. Your key and download link are emailed from licences@resynthesis.com.au. Product news is sent only if you ask for it, and every message carries an unsubscribe link.
