Common questions
Are my scanned documents uploaded anywhere?
No. Scanning, OCR text recognition, GST and receipt extraction, passport reading, and filing all run on your device. Your documents stay on your phone unless you turn on iCloud sync — which keeps them between your own Apple devices, never on our servers — or until you choose to share or export them.
Does the OCR work offline, and which languages does it read?
Yes — text recognition is fully on-device and works with no internet. It reads English, Hindi, Tamil, and Telugu and writes a searchable text layer into your PDF, so you can find any scan by the words inside it.
Is LumenScan free?
Yes, you can scan for free every day, export to PDF, and organize your documents at no cost. Pro removes the daily scan limit and unlocks GST extraction, fill & sign, password-protected PDFs, Word/PNG export, Smart Folders, and iCloud sync.
How much does Pro cost, and is there a trial?
Pro is available as a monthly or yearly subscription, or a one-time lifetime purchase, with a free trial on the yearly plan. Prices show in your local currency on the upgrade screen, and you can cancel anytime in your Apple ID settings.
How is this different from CamScanner or Adobe Scan?
LumenScan is privacy-first and built for Indian documents: OCR for Indian scripts, native GST invoice and receipt extraction, Aadhaar/PAN masking, and UPI QR detection — all on-device. Other scanners often send your pages to overseas servers to run OCR; LumenScan keeps them on your phone.
Can I lock my private documents?
Yes. A Face ID / Touch ID vault hides sensitive scans behind biometric authentication, with a device-passcode fallback so you're never locked out. You can also mask Aadhaar and PAN numbers before sharing.
Is there an Android version?
Yes. LumenScan is on the App Store and on Google Play. Scanning, OCR, and filing run on your device on both — nothing is uploaded. On Android, on-device OCR reads English and Hindi today, with more Indian scripts rolling out.
Do you show ads or sell my data?
Never. No ads and no data sale. Product analytics are anonymous and never include your document contents — the words in your scans are yours alone.
Subscriptions, billing & refunds
LumenScan subscriptions are billed through your Apple App Store or Google Play account. You can manage or cancel anytime from your store account settings — on iOS: Settings → your name → Subscriptions; on Android: Play Store → Subscriptions.
Refunds are handled by the store rather than by us: request one at reportaproblem.apple.com for Apple, or through your Google Play order history. If you hit a wall, email us and we'll do what we can to help.
Your data & account deletion
Your scans, PDFs, and OCR text are stored locally on your device. Scanning, text recognition, ID/passport and receipt parsing all run entirely on-device. You can delete your data at any time from inside the app. If you turned on cloud sync, deleting in-app also clears the synced copy.
