DocZeno Support

Last updated October 7, 2026

Need help? Email admin@richlabs.online. We usually reply within 2 business days.

To help us help you, include:

your phone model and iOS or Android version;
the DocZeno version (shown on DocZeno’s page in the App Store or Google Play);
what you were doing and what happened.

Please don’t send us private documents. A description or a screenshot with personal details covered is enough.

You can also send feedback from the app: Menu → Request a feature, or Report a bug.

Frequently asked questions

Are my documents uploaded anywhere?

No. Scanning, text recognition, search and Smart Extract all run on your phone. There’s no account and no cloud storage. A document leaves your phone only when you share or export it. See the Privacy Policy.

Text recognition missed some words. What can I do?

Scan in good, even light.
Keep the page flat and fill the frame.
Use the Document or High contrast filter.
Set the recognition language in Menu → OCR language.

Handwriting and very small print are harder to read.

Smart Extract read the wrong total or date

Automatic reading can make mistakes. Open the document’s details, correct the fields and tap Confirm details.

Dates like 02/09/2026 are read in your phone’s region format (day-first or month-first).

How do I search inside my documents?

Type in the search bar on Home or Files. Matches inside document text are listed under Inside documents. Searching inside text is part of DocZeno Pro.

How do I lock a PDF with a password?

Tools → Lock PDF, pick the file and set a password. Keep the password safe. We can’t recover it.

What is the Private Vault?

An encrypted space for sensitive documents, opened with Face ID, fingerprint or your passcode.

Vault files are hidden from search and left out of backups.
Moving files into the Vault is a Pro feature. Opening and restoring files stays free.
The Vault’s key is stored only on your device. If you delete the app, or move to a new phone without your documents, Vault files can’t be recovered. Restore files you need before you switch phones.

How do I restore DocZeno Pro on a new phone?

Open Menu → Upgrade to Pro → Restore purchases. Use the same Apple ID or Google account you bought Pro with.

How do I cancel my subscription?

iPhone: Settings → your name → Subscriptions → DocZeno.
Android: Google Play → profile → Payments & subscriptions → Subscriptions → DocZeno.

You can also go to Menu → Manage subscription in the app. Pro stays active until the end of the period you paid for.

Can I get a refund?

Purchases are handled by Apple and Google, so refunds go through them:

Apple: reportaproblem.apple.com
Google Play: refund help

How do I turn off personalised ads?

iPhone: choose “Ask App Not to Track” in the prompt, or change it later in Settings → Privacy & Security → Tracking.
Any phone: Menu → Ad privacy choices.
No ads at all: DocZeno Pro.

How do I delete my data?

Delete documents in the app, or delete the app to remove everything stored on your phone. We don’t hold any of your documents.
