General Matters

Which web browser should I use?

We use progressive web app (PWA) technology to run SomnoBot locally on your computer. Therefore, we recommend that you use recent versions of web browsers such as Chrome, Chromium, and Firefox. Chromium based browsers such as Edge will also work. We recommend that you use new versions of these browsers (v. 114 or later). We have received feedback from users that they can use SomnoBot with the Safari web browser.

Do you have access to my data to analyze sleep?

No, your polysomnographic data remain on your computer. We don't have access to your data. It is not transferred or copied to anybody. When you visit our sleep analysis website, a neural network is downloaded to your web browser. Sleep stages and spindles are detected in your web browser, which runs the neural network. All the calculations are done by your computer. There is no need for any transfer of your data to us or any other party.

Still not convinced? Try it for yourself: Once you have opened the sleep stage detection website in your web browser and the page has finished loading (this can take up to a minute depending on your internet connection), you can disconnect from the internet. You will be able to select a PSG file and let SomnoBot detect sleep stages. Note that for technical reasons beyond our control, you must disable private browsing (also called "private mode" or "incognito mode") in your browser before using SomnoBot offline.

Can I use SomnoBot to score animal data or human intracranial data?

No. The neural networks underlying SomnoBot that detect sleep stages and spindles have only been trained on scalp EEG recordings. We strongly advise against using SomnoBot for animal or intracranial data.
