1. In short

ReBrayn does not use profiling cookies, advertising or third-party analytics tools. It stores in the browser only what is needed for it to work, which is why we do not ask for your consent. The only exception is the YouTube videos that you choose to open (section 4).

2. What we store in the browser

The app does not set its own cookies: it uses the browser's storage (localStorage, sessionStorage, local IndexedDB databases, including a store of files for offline use and a technical support database, and the service worker cache) and a copy of the app for use without a connection.

• Sign-in session: used to keep you signed in securely. Duration: until you sign out, at most 7 days after your last sign-in with the password.
• Local copy of your data (library, open files, Outputs, settings) and changes not yet synchronised: used to work faster and not lose changes when the connection is missing. Duration: until you delete the Account or remove the site data from the browser; signing out does not delete it.
• Preferences (language, appearance, interface choices): used to remember how you prefer to use the app. Duration: until you change them or remove the site data.
• Language of the presentation site (rebrayn.ai): the site stores in your browser, in local storage under the name «rb-lang», the language you choose (Italian or English), to show you the pages in the same language on your next visit. It holds no other data and is not sent to us. Duration: until you change language or remove the site data.
• Pending operations (uploads, draft messages to the Tutor, sharing link opened before sign-in): used to complete them when you come back. Duration: from 30 minutes (sharing link) to [● 3 days] (drafts), then they are deleted.
• Queue of technical events (event name, codes and counts, random session and device identifiers, app version): used to send us the technical data described in the Privacy Policy (in ReBrayn: Settings › About), section 3. Duration: until they are sent, at most 7 days.
• Copy of the app for use without a connection (service worker cache): used to open ReBrayn even when the network is slow or absent. Duration: until the next update of the app.

This information is strictly necessary for the service you asked for and stays on your device, except for what the app sends to our servers in order to work.

3. How to delete it

When you delete the Account, the app deletes the local copy of your data. If you sign out of the Account, the copy stays in the browser: on a shared computer, after signing out, delete the app.rebrayn.ai data from the browser settings. Changes not yet synchronised will be lost.

4. Third-party services

• YouTube: when you open a YouTube video, the video player is loaded from YouTube's servers (Google), which may store its own cookies or similar information on your device and receives your IP address. Google's policy applies: policies.google.com/privacy.
• Payments: payment takes place on Stripe's pages, which use their own cookies according to its policy: stripe.com/privacy.

5. Changes

If we add tools that need your consent, we will ask for it before using them and we will update this page.
