Does Catadoc upload my documents anywhere?
No. Reading, search, and sharing all happen on your phone. The only thing the app ever sends is feedback, and only if you write some. Turn on airplane mode and use the app; that is the proof.
How is this different from CamScanner or Adobe Scan?
Those apps give you an image or a PDF, usually after a trip through their servers. Catadoc reads the document on the phone and keeps the useful parts: who it is from, what it cost, when it runs out. Your papers become something you can search, not just store.
What kinds of documents can it read?
Passports, invoices, receipts, contracts, insurance papers, bills. Everyday paperwork. Anything unusual still gets scanned and saved with its text; the app just extracts fewer facts from it.
Does it work offline?
Fully. Airplane mode changes nothing.
How do I get one PDF under 2 MB for a visa portal?
Pick the documents, set the cap (2 MB, 10 MB, or your own number) and share. Catadoc merges and compresses on the phone, and warns you before quality drops too far. No "compress PDF online" sites, no uploading your passport to a stranger's server.
What happens when it reads something wrong?
It will, sometimes, and it tells you when it is unsure instead of pretending. Tap the wrong value and pick the right one straight off the scan. Corrections stick, so the next receipt from the same shop arrives already fixed.
Do I need an account?
No. Nothing to sign up for, no password to forget. Delete the app and everything goes with it.
Is my library encrypted?
Yes. Encrypted at rest, with the key held in your phone's own secure keystore.
Which languages does it read?
English, German, Hindi and more.
Can I search by what's inside a document?
Type what you'd say out loud. "Bills under 2000." "Passport expiring soon." Catadoc turns that into filters you can see and remove one at a time.
Will it warn me before something expires?
Anything with an expiry date, a passport, a policy, a warranty, gets flagged on the front screen 60 days ahead. The app won't send you notifications; the warning is there when you open it.
What does Catadoc cost?
One payment, not a subscription. The trial is free for 3 days or 5 documents, whichever comes first, and the Play listing shows the price for your country. iOS comes later.
