The cookies SciVolume sets and why
2026/09/24
Effective date: 24 September 2026
SciVolume uses a small number of cookies and similar browser storage. All of them are needed to run the service; we do not set advertising or third-party analytics cookies.
| Purpose | What it does | Lifetime |
|---|---|---|
| Sign-in session | Keeps you signed in after email-code or Google sign-in and protects your account from cross-site requests; the anonymous trial workbench uses the same cookie. | Until you sign out, or 7 days |
| Language | Remembers whether you chose English or Chinese. | 1 year |
| Appearance | Remembers your light or dark theme choice. | 1 year |
We also use browser storage (localStorage) to keep an unsaved draft of the chapter you are editing so it can be recovered if your connection drops, and to remember interface preferences such as a collapsed panel. This data stays in your browser and is never sent to us.
Google sign-in briefly takes you through Google's sign-in page, and payments go through a checkout page hosted by Stripe. Those pages set their own cookies under Google's and Stripe's policies; none of them come back to scivolume.ai.
You can delete or block cookies in your browser settings. Blocking the sign-in cookie will prevent you from staying signed in. Because we set no optional cookies, there is no separate consent banner or opt-out.
If we add cookies for new purposes, we will update this page and, where required, ask for your consent first.
