Help & FAQ

Quick answers to the questions people ask most. The same help is in the app: Me → Help & FAQ.

Your files

Where are my files saved?

Inside the app on your phone, in My Files. They are private: your gallery and other apps can't see them. To keep a copy somewhere else, open the file and tap Share or Save to device.

Will I lose my files if I delete the app or change phones?

Yes - deleting the app also deletes the files inside it. Back up first: in the app go to Me → Backup and use Google Drive or “Back up all files”. On the new phone, install the app and choose Restore.

I deleted a file by mistake. Can I get it back?

Yes, for 30 days. Open My Files, tap the recycle bin at the top, then tap Restore.

Are my documents private?

Yes. Scanning, text reading, translation and editing happen on your phone. We never upload your files to our servers. Pages leave your phone only when you choose AI mode (they go to Google Gemini) or back up to your own Google Drive.

Scanning and text

How do I get a sharp scan?

Use good light and put the page on a flat, dark surface. Hold the phone straight above it and keep still. Afterwards you can drag the corners to fix the edges and use Enhance to make the page clearer.

The app read the text wrong. What can I do?

Go to Me → Text reading and choose the language of your document. The app reads English and other languages written in the Latin alphabet, Hindi and Bangla. For handwriting or blurry photos, try AI mode.

Does the app work without internet?

Yes, mostly. Scanning, PDF tools, editing and your files all work offline. Text reading and translation need internet once to download a language, then they work offline too. You need internet for AI mode, Google Drive backup and buying Premium.

AI mode

What is AI mode?

AI mode reads hard pages better - handwriting, blurry photos and complex tables - and powers Ask my files, the CV helper and AI slides. Only the pages or text you choose are sent to Google's Gemini AI. You get 5 free AI pages a day, or 50 with Premium. The count starts again every day.

Can I report a bad AI answer?

Yes. Under AI answers and AI pictures, tap “Report a problem with the AI result”. Only your reason and note are sent to us - not the answer or your files.

Premium

What do I get with Premium?

No ads anywhere, unlimited saves in the PDF editor and 50 AI pages a day. You can pay monthly or yearly. All tools stay free for everyone.

How do I cancel my subscription?

Google Play manages subscriptions. Open the Google Play app, tap your profile picture, then Payments & subscriptions → Subscriptions → FSI Doc Manager → Cancel. Premium keeps working until the end of the time you paid for. If you cancel during a free trial, you are not charged.

I paid, but Premium is not on.

Make sure your phone uses the same Google account you paid with. Then open Premium in the app and tap Restore purchase. This also works on a new phone.

Locks and passwords

How do I lock the app?

Go to Me → App lock. The app will then ask for your fingerprint or your phone's PIN each time it opens. It uses your phone's own lock, so there is no extra password to forget.

I forgot the password of a PDF.

If you opened it in the app before and chose to remember the password, it opens by itself - see Me → Saved PDF passwords. Otherwise nobody can open it, not even us. That is what keeps it safe.
