Privacy
Nothing to hide, because we hold nothing.
The shortest honest summary: your files never leave your device, analytics run only if you say yes, error reports help us fix bugs, and nothing is ever sold. The details, in plain language:

Your files
Every tool on Filum runs entirely in your browser. Your files are never uploaded, never stored, and never seen by us — there is no server copy to delete because none is ever made. Each tool ships with an automated test that fails if any request carries file data.
Analytics — only if you say yes
If you accept the cookie banner, we use Vercel Analytics and Speed Insights to see anonymous page-view and performance data (no cross-site tracking, no advertising identifiers). If you reject it, nothing runs — the tools work identically either way. Your choice is stored in your browser, not on our servers.
Error reports
When something breaks, an error report is sent to Sentry (our error-monitoring service) so we can fix it: the error itself, your browser type, and a short masked replay of the interface where all text is hidden. These reports exist to repair defects, are never used for marketing, and are deleted on Sentry's standard retention schedule.
Accounts — optional, never required
Every tool works without an account. If you choose to sign in, we store your email address and a session cookie through Supabase (hosted in the EU). That's the entire account record. Delete your account and it's gone.
Advertising
There are no advertising cookies and no ad networks on Filum today. If that ever changes, ads will load only after you explicitly consent, and this policy will be updated first — you will never be opted in silently.
Hosting
Filum is served by Vercel, which keeps standard short-lived server logs (IP address, browser type) to run and protect the service — the same logs every website host keeps. We don't sell or share any data with anyone, full stop.
