Hello there, are there any FOSS Android apps out there that serve as both a reader and a vault for PDFs? I want to be able to encrypt the PDF files and decrypt+read them with a single vault password.

I could just encrypt PDF files separately using the same password, but it’s not really that convenient having to go through several PDFs tbh.

I want to store the PDFs on the storage of my phone.

UPDATE: Safe Space is exactly what I needed, ty @[email protected], will provide a review of the app later
