The secure home for your passport, visas, residence permits and every document that's hard to replace. Snap it once — Filum files it, tracks its expiry date, and encrypts it on your iPhone so only you can read it. BUILT FOR PAPERWORK IN MORE THAN ONE COUNTRY Moving abroad means residence permits, apostilles, translated certificates, pet passports, and forms from two tax authorities. Filum keeps all of it in one place, files it automatically, and puts it in your iPhone's document picker — so when a government portal asks you to upload proof, it's two taps away. IT FILES ITSELF Snap a document and on-device AI reads it, sorts it by type, and pulls out the dates and numbers that matter. A passport becomes a passport. A lease becomes a lease. Everything becomes searchable — instantly, even offline. NEVER MISS A RENEWAL Radar tracks passports, visas, residence permits and insurance, and warns you before they lapse. It counts to the six-month validity rule most destinations enforce, not the date printed on the document. ONLY YOU HOLD THE KEY Every file is encrypted with AES-256-GCM on your iPhone before it syncs. Your keys are derived in the Secure Enclave and never sent to our servers. We store ciphertext and nothing else. What we can't see: • Your documents • Filenames, types, or extracted fields • Your encryption key All we hold are encrypted blobs and the sizes and timestamps needed to sync them. YOURS TO KEEP Export your entire vault any time. No lock-in. The only way back into your vault is a 24-word recovery phrase that belongs to you alone — we can't recover it for you, and that's exactly the point. OPEN CORE Filum's encryption core is open source under MIT. Read it instead of taking our word for it: github.com/CorvidSoft/filum-crypto FREE TO START Store up to 25 documents for free. Filum Pro removes the limit, monthly or yearly. Privacy Policy: filumapp.com/privacy Terms of Service: filumapp.com/terms
