Privacy Policy

What FOMO is
FOMO is a browser extension and web app that tracks what you pay attention to online — page titles and URLs — and shows you a live feed of what people with similar interests are reading and watching. Everything is anonymous by default. No account is required.
What we collect
To classify what you're reading into interest categories.
A randomly generated ID stored in your browser. Not linked to your name, email, or identity.
To measure attention — how long you actually spent on something.
Inferred from your browsing, stored on our servers to power the pulse feed.
What we never collect
Your name, email, or any personally identifiable information (unless you voluntarily join the waitlist)
Passwords, form inputs, or anything you type
Messages, emails, or private communications
Content from banking, health, or other sensitive pages (these are automatically excluded)
Your precise location
How we use your data
We use your browsing signals to:
- Build your anonymous attention profile (shown only to you on the Mirror page)
- Contribute anonymously to the community pulse feed
- Improve classification accuracy over time
We do not sell your data. We do not share it with advertisers. We do not use it for any purpose other than running FOMO.
How data is shared
Your browsing signals contribute anonymously to the community pulse. Other users see aggregated topic trends — never individual browsing activity, never your user ID, never anything that could identify you.
We use Anthropic's Claude API to classify page content. Page titles and URLs are sent to Anthropic for this purpose. See Anthropic's privacy policy.
We use Supabase to store data. See Supabase's privacy policy.
Your rights
You can delete all your data at any time from the Settings page. This permanently removes all browsing signals, your anonymous profile, and your user record from our servers.
You can pause tracking at any time by toggling the extension off. No new signals will be collected while paused.
If you joined the waitlist and want your email removed, contact us at hi@usefomo.co.
Children
FOMO is not intended for children under 13. We do not knowingly collect data from anyone under 13. If you believe a child has used FOMO, contact us and we will delete their data immediately.
Data retention
Browsing signals are retained for as long as you use FOMO. You can delete them at any time. If you have not used FOMO in 12 months, we may delete your data automatically.
Changes to this policy
We may update this policy as FOMO evolves. If we make material changes, we will update the date at the top of this page.
