Cookie Policy.

Reaction uses a small number of cookies and similar storage to make the service work and remember your preferences. We don’t use advertising cookies and we don’t share your data with third-party advertisers.

What cookies are

Cookies are small files your browser stores when you visit a website. They let the site remember things between page loads — like whether you’re signed in. We also use localStorage, a similar technology that lives in your browser and works much the same way.

Cookies we use

Strictly necessary

These cookies are essential for Reaction to work. You can’t opt out of them — without them, signing in and using the service wouldn’t be possible.

• Session cookie — keeps you signed in between pages. Expires when you sign out or after a period of inactivity.
• CSRF token — a security cookie that prevents malicious sites from acting on your behalf.

Preferences (localStorage)

These remember your in-app choices. Stored locally in your browser, not sent to our servers:

• Theme — whether you prefer light or dark mode
• Install prompt history — so we don’t keep asking you to install the app if you’ve already dismissed the prompt
• Notification prompt history — similar, for the “allow notifications” prompt

Performance (optional)

We may use Vercel’s built-in analytics to understand which pages people use and where the app is slow. These are first-party, anonymous, and don’t track you across other websites.

Managing cookies

You can clear cookies and localStorage from your browser’s settings at any time. Doing so will sign you out of Reaction and reset any in-app preferences.

Most browsers also let you block cookies entirely — but Reaction won’t work without the strictly necessary ones, so you’d need to allow them at least for our domain.

Changes to this Policy

If we change which cookies we use, we’ll update this Policy and the “last updated” date above.
