Scan
Live page-edge guidance with automatic steady-frame capture, true perspective correction, colour / grey / B&W filters and multi-page sessions.
Offline document suite for Android, Windows and the web
Your Documents. Your Control.
Scan, read, annotate, edit, sign and organise PDFs and documents on Android, Windows or in your browser - with no ads, no accounts and no subscription. The Play build has no internet permission at all, so DOCKET cannot send your files anywhere. The optional direct-download build only contacts our signed update manifest. Sync between devices is optional and end-to-end encrypted.

Tools
Everything a PDF suite should do.
Nothing it shouldn’t.
OCR Pro
On-device text recognition adds an invisible layer, so scans become searchable and copyable — still with no upload.
Read & annotate
Fast rendering, page or continuous scrolling, resume-where-you-left-off, bookmarks, PDF contents, an annotation panel, read-aloud, local library search, highlights, ink, sticky notes, reusable signatures (Pro) and night reading mode.
Edit text
Select a line of digital PDF text and replace or delete it. The original text is removed from the text layer, not just covered with a white box. Scans are excluded.
Prepare & sign Pro
Add recipients in order, place signature, initials, date, text and checkbox fields, then fill and flatten a signed copy.
Templates Pro
Start from a guided agreement, or save your own PDF with fields as a reusable template, then create a fresh fillable copy whenever you need it.
Organise
Projects, nested folders and an Unfiled inbox keep the library under control. Each project has a dashboard for unresolved signing items, recent documents and tag counts. Tag contracts, estimates and invoices, multi-select to move or share, sort by recent/name/size, and restore anything from Trash.
Convert
Images to PDF, pages to images, text and Markdown to PDF, plus local Word, HTML, RTF, ODT and EPUB reading.
Protect
AES-256 password copies, metadata editing, watermarks and flattening — all written locally.
Forms Pro
Fill text fields, checkboxes, radio groups and choice lists, then flatten the answers into the page.
Batch Pro
Export every page as a PNG or split a document into one PDF per page, straight into a folder you choose.
A look inside
Designed for documents, not for ads.
Pricing
Free is a real app.
Pro is a one-time unlock.
The free version reads, annotates, scans, merges, splits and exports. Pro adds the tools that are expensive to build — signatures and the signing workspace, OCR, form filling, reusable templates and batch automation — for a single payment. No subscription, no expiry, no watermark.

Privacy by construction
No internet permission on Play.
Read that again.
The Play build does not request the Android INTERNET permission. There is no
analytics, no advertising SDK and no cloud processing. Camera scans, OCR and PDF edits run
on your phone. Files live in the app's private storage, and uninstalling removes the app's
private copy.
The optional direct-download build adds one HTTPS request to a signed update manifest. It sends no document data, no analytics and no account information.

Built by Off Rails.
DOCKET is a product of Off Rails. We build offline-first tools for everyday document work — software that does its job and then gets out of the way.
Questions go straight to the people who build it. No ticket queues, no chatbots.
Questions
Good to know.
Does it really work offline?
Yes. The Play build has no internet permission, so every feature — including OCR — runs locally. The direct-download build only contacts our signed update manifest; it does not upload documents, send analytics or create an account.
Where are my files stored?
DOCKET keeps its own copy in private app storage, so edits never touch your originals. Removing a document deletes that copy; uninstalling removes the app's private copy.
What does Pro cost?
$9.99 at launch, $12.99 afterwards — one time. It unlocks the signing workspace, OCR, form filling and batch automation. Everything else stays free forever.
Which versions of Android are supported?
Android 8.0 and newer. The app is built for phones and works in portrait or landscape.
Can I use it for work?
Yes — invoices, contracts, scans, forms and signatures are everyday use. Check your organisation’s policies before processing confidential documents on a personal device.
When is it on Google Play?
It is in final preparation. Email admin@off-rails.com for early access.
