Privacy: what leaves your computer
Last updated 9 October 2026
Your prompts never leave your computer. Not when you save them, not when you search, and not when you enhance them, because the model runs on your machine. ThatPrompt does talk to the internet for a few other things, and this page lists every one.
What never leaves your computer
- Your prompts, titles and folders. They live in a file on your computer. See Where your data lives.
- Everything Enhance reads and writes. The model runs locally, and works offline once it's downloaded.
- Your exports. They're files you save where you choose.
Every connection ThatPrompt makes
| What | When | What's sent |
|---|---|---|
| Sign in | When you choose Sign in or Create account | Your browser opens our sign-in page, and you type your email and password there. The app then receives a sign-in token. |
| Licence check | When ThatPrompt starts, when the Licence screen shows, and when you choose Check licence | Your sign-in token. The answer is your email and your licence. |
| Staying signed in | Every so often while you use it | Your sign-in token and a random ID for this computer, so your licence can count your devices. |
| Update check | When ThatPrompt starts, every 30 minutes, and when you open it | Nothing but the request for a small file listing the latest version. Like any web request, it includes your IP address, which we use to count roughly how many copies of ThatPrompt are running. |
| Model download | When you pick a model | A download from Hugging Face, where the model's makers publish it, with ThatPrompt's version and your operating system. |
| Feedback | When you choose Send | Your message, your account email so we can reply, the app version and your operating system. |
| Usage analytics | Only if you turned them on | Anonymous events, never text. See Turn usage analytics on or off. |
That's the full list. ThatPrompt contains no advertising or third-party analytics code.
Where it goes
Sign-in, licences, feedback and analytics go to ThatPrompt's own server, run by Black Lab Studios, Lda in Microsoft Azure. Payments are handled by Paddle on the website, never in the app. The privacy policy has the legal detail: what's kept, for how long, and your rights.
Why this matters for a prompt manager
Prompts carry the context you give an AI: code, customer details, plans. A tool that sends them to a server to "improve" them is one more place they can leak from. ThatPrompt was built so there's nothing to leak, which is also why it can't sync your library between computers.
