Manila is an offline PDF toolkit for Android. Everything runs on the device — the app never uploads, stores, or transmits the user's documents or photos to any server. Free tools: convert photos into a PDF (taken with the camera through the system capture screen, or chosen from the gallery) with page size, margin and quality options; merge several PDFs into one; split a PDF or extract a page range; and organize pages (reorder, rotate, delete). The free tools have no page limit and add no watermark. PRO tools (unlocked by an auto-renewing subscription sold through Google Play Billing, product manila_pro_monthly with a 3-day free trial): compress a PDF (three quality presets; the JPEG images inside are re-encoded while the text layer is kept), password-protect a PDF or remove a known password (AES-256 via a bundled qpdf WebAssembly engine), true redaction that rebuilds the marked pages from an image so the covered words are removed from the file rather than hidden behind a black box, add a watermark, add page numbers, and export every page as a JPG image. There is no signature tool. There are no accounts, no sign-in, and no ads. There is no advertising SDK, no analytics SDK, and no crash-reporting SDK in the app. The app has no server of its own. Permissions: INTERNET is the only permission in the manifest, requested for exactly two purposes — Google Play Billing (subscription purchase and restore) and fetching a small remote configuration file that contains no user data and no identifier. Photos and PDFs are reached through Android's own file picker, and the camera through the system capture screen, so the app holds no persistent camera or storage permission; the user chooses each file explicitly.
