PaperGuard for iPhone

Support

Start here for questions about scanning, OCR, the Vault, or your subscription. PaperGuard is made by a one-person studio — emails are read by the developer, not a ticket bot.

Helpful details for a first message: iPhone model, iOS version, app version, and the steps that led to the issue. Never attach scans of IDs, passports, or other sensitive documents — we don't need them to help you, and your documents should stay on your device.

Common questions

The scanner won't open or shows a black screen

Check that PaperGuard has camera permission in iOS Settings → Privacy & Security → Camera. If it does, close the app fully and reopen it; a device restart clears stubborn camera sessions.

Edge detection misses the page

More light and a contrasting background help most. For tricky documents switch to the Manual Camera in the Scan tab and frame the page yourself; you can adjust corners before saving.

OCR text looks wrong or is missing

Check Settings → OCR Languages and make sure the document's language is selected. Recognition runs on-device — a sharp, well-lit scan makes the biggest difference. The free plan shows the first lines as a preview; full text and search are part of Pro.

Face ID doesn't unlock the Vault

iOS handles the Face ID prompt itself. If it fails, use your device passcode as the fallback. Make sure Face ID is enabled for PaperGuard in iOS Settings → Face ID & Passcode → Other Apps.

A document doesn't appear in iPhone search

Spotlight indexes document titles; indexing of document text is off by default and can be enabled in Settings. Identity cards and passports are never indexed by content — by design, for your safety.

Restore Purchases doesn't bring Pro back

Make sure you're signed in with the same Apple ID that started the trial or purchase, then use Restore Purchases in Settings. Subscription state comes from the App Store, so a working internet connection is needed for that one step.

How do I cancel the trial or subscription?

iOS Settings → your Apple ID → Subscriptions → PaperGuard Pro → Cancel. Canceling during the 7-day trial of the yearly plan means you won't be charged; the monthly plan has no trial and is billed on purchase. Apple handles all billing; we never see your payment details.

How do I move documents to a new iPhone?

PaperGuard has no cloud sync by design. Your documents transfer with your normal encrypted iPhone backup (iCloud or computer) when you set up the new device. You can also export important documents as PDFs before switching.

How do I delete everything?

Settings → Clear All Data wipes every document, folder, tag, and signature at once. Deleting the app does the same. Nothing exists anywhere else, so that's the whole story.
