Your voice never leaves your machine.
Blurt does speech recognition on your own computer. This page explains exactly what that means, what little does get sent to us, and what we hold about you.
Last updated: August 21, 2026
The short version
The same is true of the text Blurt produces. Transcripts are written to a file on your machine and stay there. We hold no copy. We cannot read your transcripts, and we cannot recover them for you if you delete them.
“Polish”, which cleans up your dictated text, also runs locally using a model on your machine. It makes no API call and sends nothing anywhere. Meeting Mode captures system audio on your machine and follows exactly the same rules as normal dictation.
What does leave your machine
We would rather state this plainly than bury it. Once you have activated a licence, Blurt makes these network requests and no others on your behalf:
- A licence check, about once a week. Blurt sends your licence key to our server so we can confirm the subscription is still valid. The request also carries basic device information: your operating system name, the Blurt version you are running, and a device label taken from your computer's hostname so that you can tell your own devices apart when managing them. Nothing else.
- Activation. When you first enter a licence key on a device, Blurt sends the same information to claim that device's slot against your licence.
- Update checks. Blurt checks whether a newer version is available.
That is the complete list. No audio, no transcripts, and no content of any kind is included in any of these requests. If we ever add to this list, this page will say so before the change ships.
What we never collect
Stated explicitly, because privacy policies usually only tell you what is taken. We do not collect, receive, or store:
- Your audio, or any recording of it
- Your transcripts, or any text you dictate
- What you dictate about, or any analytics derived from it
- Your keystrokes
- The contents of your screen, or the apps you dictate into
- Your files or documents
What we hold about you
If you buy Blurt, we hold your email address, which plan you bought, whether your subscription is active, your licence key, and which devices that key is activated on. That is the entire list.
We run no database of our own. Our licensing server is a stateless proxy: it passes your licence key to Polar, returns the answer to your app, and keeps nothing. The record of your purchase lives with Polar, described below.
Why we hold it, and on what basis. We process your licence and subscription data to give you the software you paid for, which is performance of our contract with you. We check for updates on the basis of our legitimate interest in keeping installed software working and secure.
Payments
We never see your card details. Not the number, not the expiry, not the security code. Payments are processed by Polar (polar.sh), which acts as our merchant of record, meaning Polar is the seller of record for your purchase and handles payment processing and sales tax.
From Polar we receive your email address, the plan you bought, your subscription status, and your licence key. Cancellations, invoices, and card changes all happen in Polar's customer portal, not with us.
Who else is involved
- Polar processes payments and issues licence keys, and holds your customer record as described above.
- Vercel hosts this website and the licensing endpoint your app talks to. Like any web host, it processes the IP addresses of incoming requests in order to serve them.
- Google Analytics, loaded through Google Tag Manager, measures traffic on this website. It sets cookies in your browser and collects your approximate location derived from your IP address, along with browser and device information. This applies to this website only. The Blurt desktop app contains no analytics and sends us nothing about how you use it.
How long things are kept
Licence and subscription data is kept for as long as your licence is active, and afterwards for as long as Polar needs it to meet tax and accounting obligations.
Everything Blurt creates on your machine stays on your machine, and you can delete it yourself at any time. Your transcript history lives in history.json inside Blurt's folder:
- macOS:
~/Library/Application Support/then the Blurt folder - Linux:
~/.local/share/then the Blurt folder - Windows:
%APPDATA%\then the Blurt folder
Deleting that file removes your transcript history permanently. Because we never had a copy, we cannot restore it.
Your rights
You can ask us for a copy of what we hold about you, ask us to correct it, or ask us to delete it. Since what we hold is limited to your email, plan, subscription status, licence key and its activations, these requests are quick to answer.
Email contact@evolveratechnologies.com and we will respond within 30 days. Deleting your licence data ends your ability to activate Blurt on new devices, so we will confirm before doing it.
Depending on where you live, you may also have the right to object to processing, to restrict it, or to complain to your local data protection authority.
Children
Blurt is not directed at children. We do not knowingly collect information from anyone under 13, or under 16 in the European Union. If you believe a child has provided us with information, email us and we will delete it.
Changes to this policy
If we change what Blurt sends or what we hold, we will update this page and change the date at the top before the change ships. For anything that meaningfully affects your privacy, we will also say so in the app's release notes.
