Lipik Reader quick help
A password-protected PDF will not open
Confirm the password and capitalization. Lipik uses the password only for the current session. It does not remove DRM or recover forgotten passwords.
A MOBI or AZW book is rejected
Lipik can identify Kindle containers and DRM, but shipping builds do not claim MOBI/AZW rendering until a legally approved, tested parser is selected. DRM-protected Kindle books must be opened in an authorised reader.
My annotations are missing from the shared PDF
Current Lipik annotations are stored locally as app overlays. PDF page operations create new document files, but overlays are not embedded or flattened into those files.
Advertisements do not load
Core reading remains available. Ads require internet access and may be unavailable because of connectivity, consent, region, inventory or frequency limits.
