Frequently Asked Questions
Which file types can Dubo open?
Dubo opens PDFs and other common document formats. If a file won't open, contact us with the file type and we'll look into it.
How do I open a document?
Open Dubo and choose the file you want to read from your device. You can also open a document from your file manager and pick Dubo to open it.
Can I zoom and scroll through long documents?
Yes. Pinch to zoom and scroll smoothly through pages. Dubo is built to stay fast and comfortable on long documents.
Will Dubo remember where I stopped reading?
Yes. When you reopen a document, Dubo takes you back to where you left off.
Does Dubo require an internet connection?
No. Dubo reads files stored on your device, so you can read offline.
Are my documents uploaded anywhere?
No. Your documents are opened and read on your device and are not uploaded to us. Dubo does not require an account. For more information, see the Dubo Privacy Policy.
How do I clear my reading history?
Open your phone's Settings, go to Apps, select Dubo, then Storage, and choose Clear data. This removes Dubo's saved reading positions and settings. Your original documents are not deleted.
A document looks wrong or won't load. What should I do?
Please contact us and include your device model, Android version, the file type, and roughly how large the file is. If you can share the file, that helps even more.
Can I suggest a feature?
Absolutely. Send us your idea and we'll take a look.
