Bindery: Looking for closed testers for a fully offline, zero-network-permission PDF toolkit [GPL-3.0]
License: GPL-3.0 (Open Source)
Source Code: https://github.com/YUSAKRU/bindery
Hello everyone,
I've built Bindery, an Android PDF utility app focused entirely on privacy and offline usage. By design, the app has absolutely no internet permission in its manifest, meaning your documents never leave your device.
What the app does:
* Create PDF booklets (signature/saddle-stitch layouts - quite rare to find offline on Android)
* Merge, rotate, and number pages
* Built-in PDF reader with landscape mode & night theme
* Image-to-PDF conversion with automatic perspective warping correction
* Custom watermarking
What I'm looking for:
Google Play Console requires me to have at least 12 testers opt-in for 14 continuous days before going public. I am looking for testers who actually use PDF tools on a regular basis, are willing to keep the app installed for the test duration, and can share some honest feedback.
What you get:
* Ad-free, tracking-free, and fully offline early access to the app.
* Fully verifiable privacy claims via the public GitHub repo linked above.
* Access to a self-hosted community hub (uses Google OAuth for convenience, no separate account creation needed, and features full delete-on-demand) where you can report bugs privately or chat about the project.
How to join the closed test:
I set up a self-hosted signup hub to automate the Google Group onboarding process:

Thank you for your time, and I look forward to your honest feedback!
