Help & FAQ

Tap the camera button on the Documents tab. Point at the document on a flat surface with good lighting. ScanSmart auto-detects the borders, corrects the perspective, and lets you tweak the crop or add more pages before saving.

Edge detection works best with high contrast between the document and the background. Try placing the page on a darker, plain surface, increase ambient light, and avoid casting shadows directly onto the page. You can always adjust the crop manually in the review screen before saving.

In ScanSmart v1, you can scan as many pages as you like into a single document. Performance depends on your device's available memory; very long documents may take a moment to render or export.

For best OCR results, scan each receipt as its own page or document. Multiple small items on one page can confuse edge detection.

OCR runs entirely on your phone using Google ML Kit. Your scan images never leave the device for text extraction.

ScanSmart v1 supports Latin-script languages (English, French, German, Spanish, Portuguese, and most European languages). Support for Chinese, Japanese, Korean, and other scripts is planned for a future release.

Open the document, tap "View extracted text (OCR)," and use Copy All to bring the text into a notes app where you can edit it. In-app editing of OCR text is on the roadmap.

Go to the Folders tab and tap the + button. Folders are used to group related documents — for example, "2026 Receipts," "Tax Documents," "Travel."

Long-press the document in the library, choose Rename, and type the new name. You can also rename from inside the document.

Deleted documents go to the Trash and stay there for 30 days, so accidental deletes are recoverable. After 30 days they are permanently removed. To delete immediately, go to the Trash and choose "Permanently delete."

PDF (multi-page) and JPEG (one file per page). Pick the default in Settings → Export → Default Export Format, or choose per-document from the share sheet.

Open the document, tap the share icon, choose Format and Quality, then pick the destination app (email, messaging, drive, etc.) from Android's system share sheet.

No. ScanSmart works fully in Guest mode — your scans are saved locally on your device. Creating an account lets you back up your scans and recover them if you change phones.

On the Sign In screen, tap "Forgot Password?" and enter your email. If we find an account for that address, we'll send you a reset link that expires in 15 minutes. Open the link on any device and choose a new password.

Check your spam folder first. The sender is noreply@scansmart.app. If it isn't there after 5 minutes, try the Forgot Password flow again, double-check the email is the one you registered with, and email support@scansmart.app if it still doesn't arrive.

Yes — sign in on each device with the same email. Cloud backup of your documents across devices is rolling out gradually; in v1, documents created on one device may not yet appear on another. We'll announce when cross-device sync is fully live.

Settings → Account → Delete Account. We mark the account for deletion and permanently remove your data after a 30-day grace period. Change your mind in the meantime? Email support@scansmart.app from the address on the account.

In Guest mode, no — everything stays on your device. With an account, scan metadata (titles, folders, dates) and optionally the images themselves may be stored on our servers so you can access them on other devices. See the Privacy Policy for details.

No. We do not use your Content to train machine-learning models, and we do not share it with advertisers. OCR runs locally on your device using on-device ML Kit, not a cloud model.

Settings → Privacy & Security → App Lock. Toggle it on; you'll be asked to confirm with your fingerprint, face, or device PIN each time you open the app.

Yes. The current version is fully free and contains no ads. A paid "Pro" tier with additional features (multi-language OCR, cross-device cloud sync, advanced export, biometric app lock guarantees) is planned for a future release. Existing free features will remain free.

Force-stop the app from Android Settings → Apps → ScanSmart, then launch again. If the issue persists, uninstall and reinstall from the Play Store. Your local data lives in the app's storage and will be cleared by an uninstall — if you have an account, sign in again to recover any data that was backed up.

Close other camera-using apps in the background. Lower-end devices may run more smoothly if you exit and reopen the app between long scanning sessions.

This usually means a temporary configuration issue on our end or a transient Google Play Services outage. Use email sign-in instead, or try again in a few minutes. If it persists, email support@scansmart.app with your device model.

The fastest path: Settings → Help → Report a Bug. That opens an email pre-filled with your app version and device model. Or email support@scansmart.app directly with a short description and, if possible, a screenshot or screen recording.
