Privacy

Speaku is built so your voice stays on your computer. This notice explains what the app — for Mac and for Windows — and this website do with data. Last updated: November 2026.

The app

Audio and transcripts

Speech is recognised on your computer. Dictation audio is transcribed and then discarded; meeting recordings and transcripts are stored in ~/Library/Application Support/Speaku on a Mac and in %LocalAppData%\Speaku on Windows, and nowhere else unless you set up a storage bucket of your own. There is no account, and nothing you say, dictate or record is ever sent to us.

Language models you configure

If you set up a language model to polish dictations or write meeting notes, the text of the dictation or transcript is sent to the service you chose, under that service's terms and privacy policy. Speaku shows where text will be sent before you save such a setting. If you use a model running on your computer, no text leaves it.

Downloads and updates

Speech and speaker models are downloaded from Hugging Face and GitHub when you choose them. Once a day, Speaku asks our update server (STACKIT Object Storage) whether a newer version exists. These requests reveal your IP address to the server answering them, like any download; they contain nothing about you or your use of the app.

How many people use Speaku

So we know how many copies are in use, Speaku sends one short message a day to our server on STACKIT in Germany. It contains exactly three things: a random number made up by the app the first time it runs, the version of Speaku, and whether it is the Mac or the Windows app. It contains nothing about you, your computer, what you dictate or record, or which apps you use, and the random number cannot be traced back to you. The server keeps those three fields for 180 days and does not store your IP address. Our legitimate interest in knowing how many people use the app is the legal basis (Art. 6(1)(f) GDPR).

You can turn this off at any time under Settings → General → Count this Mac as one in use (on Windows: Count this PC as one in use). The app then stops sending it and forgets its random number; if you turn it on again later, it is counted as a new copy. Development builds never send it.

No other analytics

Speaku contains no other analytics, tracking or advertising code, and does not report crashes or what you do in the app to us.

This website

speaku.app and the downloads of Speaku are served from STACKIT Object Storage, STACKIT Cloud Foundry and STACKIT CDN in Germany. STACKIT processes the IP address of visitors to deliver the pages and files and to keep the service secure. This website sets no cookies and uses no analytics.

Contact and your rights

The controller responsible under the GDPR is the operator of Speaku, reachable at support@speaku.app. You can ask what data about you we hold, have it corrected or deleted, restrict or object to its processing, and complain to a data protection supervisory authority. The daily count holds only a random number we cannot connect to you; to have yours removed, turn the count off and it is no longer sent. A request will usually be about an email you sent us: write to support@speaku.app.
