How can we help?

On Google's permission screen the Drive box starts unticked. Connect again and tick "See, edit, create and delete only the specific Google Drive files you use with this app". Sheafly still can't see anything else in your Drive.

Check the sync bar on the Storage & privacy screen. If "Upload on Wi-Fi only" is on, scans wait for Wi-Fi. If it asks you to grant access, your drive sign-in has expired; tap "Grant access". Scans are always saved on the device first, so nothing is lost while they wait.

Open Storage & privacy and tap "Switch" next to your drive. Your existing files stay in the old drive; use "Export everything" if you want to take them with you.

Yes. Connect both to the same drive account and Sheafly will pick up the library from the drive.

In a folder named Sheafly, with a folder inside for each person. On OneDrive and Dropbox it sits in Sheafly's app folder.

On the crop screen, drag the corners to the page's real edges. You can re-crop, rotate or change the filter of any page later from the document's page view.

Check that "Read text in the background" is on. If the page is marked unclear, the phone's text engine couldn't read it with confidence, which happens with handwriting, very small print and non-Latin scripts. Searching the words inside pages is part of Sheafly Pro; the free version finds documents by name, person and folder. You can also rebuild the search index from Storage & privacy.

Switch the camera to "ID card", capture the front, then the back. Sheafly lays both out at true size on one A4 page. The free version makes 2 card sheets; Pro has no limit.

For a PDF from your files, open "Sign a PDF" in the library. For one of your scans, open it, tap share and turn on "Sign this PDF". Draw your signature, tap the page where it goes, then drag to move it or pull the corner to resize. Tick "Keep on this device" to reuse it next time; it is never uploaded.

Open "Merge PDF files" in the library and add two or more PDFs in the order they go. The result keeps each file's text, links and drawings. Share it, or save it to the library so it is filed and searchable like a scan. To combine two of your scans instead, use "Select to merge" in the library.

Sheafly does not keep PDF passwords, so it can't be recovered. The original document is still in your library: share it again with a new password.

The free version signs 3 PDFs, password-protects 3 PDFs and merges PDFs 3 times. Sheafly Pro removes these limits.

Open Sheafly Pro from the Storage & privacy screen and tap "Restore purchases", signed in with the Apple ID or Google account you bought it with.

On iPhone, go to Settings › your name › Subscriptions › Sheafly, or tap "Manage subscription" in the app. Cancel at least 24 hours before the period ends to avoid renewal. Refunds are handled by Apple at reportaproblem.apple.com. On Android, open Google Play › your profile › Payments & subscriptions › Subscriptions › Sheafly.

Open Storage & privacy and tap "Ad privacy choices". This row appears where consent is required in your region.

In Storage & privacy, "Disconnect and erase locally" removes the library from your phone. To delete the files themselves, delete the Sheafly folder in your drive. Deleting the app removes anything left on the device. See the privacy policy for details.
