Scanizma
The document scanner that can't upload your documents
Scanizma is a document scanner that removes the INTERNET permission from its manifest. It is not a privacy promise — the capability is not there. An in-app "Offline proof" screen reads your device's own permission list so you can verify it yourself. On-device: live edge detection, OCR in 5 scripts, searchable PDFs, DOCX/XLSX export, encrypted vault, permanent redaction, ID photo sheets, book mode. No watermark. No ads. No subscription. No account.
Hi Product Hunt 👋
I built this because every scanner app I tried wanted an account, a subscription, or put a watermark on my documents — and every one of them could upload whatever I scanned.
Scanizma removes INTERNET and ACCESS_NETWORK_STATE from its merged manifest. Not "we promise not to upload" — the permission is not there, so it cannot. There is a screen in the app that reads the device's own package manager and shows you the actual permission list, so you do not have to take my word for it. You can check the same list in Android Settings → Apps → Scanizma → Permissions.
Everything runs on device: edge detection (custom detector + OpenCV), OCR via ML Kit in five scripts, searchable PDF output, DOCX/XLSX export, an encrypted local vault, and permanent redaction that also clears the OCR cache — otherwise the blacked-out text would still be readable from a stale search index.
Free, no ads, no subscriptions, no account. I am not monetising it.
The one thing it is not: it cannot do anything that needs a server. No cloud sync, no Office-to-PDF conversion. There is a "How do I…?" screen that points you to free alternatives for those instead of pretending they are coming soon.
Happy to answer anything about how the offline detection works.
