1. Cookies and browser storage
Cookies are small text files a website stores in your browser. Websites can also keep information in browser storage, such as local storage and IndexedDB. This policy covers both.
2. Cookies we set
We only set cookies that features of the Service need:
| Cookie | Purpose | Duration |
|---|---|---|
OPENNAN_LOCALE | Remembers the language you chose. | 1 year |
ref | Remembers the referral code from a referral link, so the person who referred you is credited when you sign up. | 30 days |
sidebar_state | Remembers whether the app sidebar is open or closed. | 7 days |
3. Browser storage
We also keep a few things in your browser's storage. They stay until you sign out or clear your browser data:
| Item | Purpose |
|---|---|
| Sign-in | Keeps you signed in. Stored by Google Firebase Authentication. |
| Theme | Remembers light or dark mode. |
| Cookie notice | Remembers that you answered the cookie notice. |
| Drafts and preferences | Unsent chat messages, AI assistant settings, editor markers, recent imports, a song to MIDI import in progress, the playground options you left open, and your playground runs, which are kept only until you close the tab. |
4. No analytics or advertising cookies
We do not use analytics or advertising cookies, and we do not use Google Analytics or any advertising tools. To count page visits, we use Cloudflare Web Analytics, which counts visits without cookies or cross-site tracking. We do not track you across other websites, so there is nothing for a Do Not Track signal to turn off.
5. Other websites
When you pay, you go to Stripe's checkout page, and when you sign in with Google you use Google's sign-in window. Those services set their own cookies under their own policies, such as the Stripe Privacy Policy.
6. Your choices
Because we only use cookies and storage the Service needs, both buttons in the cookie notice keep them; choosing “Reject Non-Essential” changes nothing today, as we have no non-essential cookies.
You can block or delete cookies and browser storage in your browser settings. If you do, you may be signed out, the site may switch back to your browser's language, and a referral may not be credited.
