Privacy
We hold what you give us, no more.
The short version: on-device tools never send your files anywhere; server-side converters process and delete within 60 minutes; analytics run only if you say yes; nothing is ever sold. The details:

Your files
Filum has two modes. On-device tools (split, merge, rotate, sign, organize, redact, and more) run entirely in your browser — your file never reaches a server. Server-side converters (Word, Excel, PowerPoint, EPUB, and other format conversions) send your file over HTTPS to a processing server, convert it, return the result, and delete the file within 60 minutes — never stored permanently. Which mode a tool uses is stated on its page.
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.
