Cookie Policy

October 21, 2026

This Cookie Policy explains how Fuser Technologies, Inc. ("Fuser," "we," "us," "our") uses cookies and similar technologies when you visit fuser.studio, use the Fuser app at app.fuser.studio, or use any other site or service we operate that links to this policy (together, the "Service"). It also covers similar technologies, such as browser storage, session replay and partner tags. Read it together with our Privacy Policy.

The categories we use

Essential cookies keep you signed in, keep the Service secure, protect against bots, and remember your cookie choice. You can't turn them off in our settings.

Functional cookies remember your settings, such as theme, language and your last workspace.

Analytics cookies help us understand how the Service is used: PostHog for product analytics, Google Analytics 4 (through Cloudflare Zaraz), and session replay in the app from PostHog and Sentry. PostHog replays can include text you type (except passwords), what appears on your screen including your canvas, and browser console messages; Sentry replays hide text and media. If you are signed in, analytics data is linked to your account.

Marketing cookies help us measure our advertising and show our ads to you on other sites and apps: Google Ads, Meta (Facebook/Instagram), TikTok, Reddit and X (through Cloudflare Zaraz); Apollo, which identifies the company associated with a visitor's IP address (fuser.studio only); and Dub, which attributes sign-ups and purchases to referral links. Some US state laws call this "sharing" personal data for "cross-context behavioral advertising" or "targeted advertising".

Your choices by location

European Economic Area, United Kingdom and Switzerland (and visitors whose location we can't determine): we ask before using analytics or marketing cookies. Until you choose, only essential and functional cookies are used. Declining is as easy as accepting.

Everywhere else, including the United States: analytics and marketing cookies are on by default and you can opt out at any time.

Global Privacy Control: if your browser sends a GPC signal, we treat it as an opt-out of marketing cookies and of sharing for targeted advertising, wherever you are. It does not affect analytics cookies, which you can turn off separately.

How to change your choice

  • On fuser.studio: Your Privacy Choices at the bottom of any page.
  • In the app: Settings → Notifications → Cookies.
  • In your browser: block or delete cookies (blocking essential cookies stops you signing in).

Declining analytics or marketing doesn't change how the Service works. If you decline analytics, PostHog counts visits without cookies or a persistent identifier, and no session replay is recorded.

How we remember your choice

We keep your choice for 12 months and, when you're signed in, save it to your account so it follows you to other browsers. When you sign out, we clear it from that browser so the next person is asked again.

Server-side measurement

When you sign up, start generating, start a checkout or make a purchase, publish, or deploy an app, our servers may send that event to our advertising partners. These messages can include a hashed copy of your email address, your IP address and browser user agent, and the partner identifiers in your cookies. We send them only when your marketing choice allows it.

Emails

Our marketing emails contain a small pixel and tracked links (through our email provider, Resend) that tell us whether an email was opened and which links were clicked. The cookie banner doesn't control this; turn off automatic image loading in your email app or unsubscribe using the link in any marketing email.
