Frequently Asked Questions
Is the app free?
Yes. Completely. No subscription, no in-app purchases, no ads, no trial. Download once and use without limits.
Are my files uploaded anywhere?
No. The app is fully offline. All operations (compression, merging, OCR, etc.) run on your iPhone. No document ever leaves your device.
What languages does OCR support?
Russian and English. Both are recognized on-device via Apple's Vision framework, no server involved.
A password-protected PDF won't open
The app supports entering a password during import. When you pick an encrypted PDF, a separate sheet opens with a password field. Enter it and the file unlocks for further work. The original stays unchanged on disk.
Compression didn't reduce the file size
If your PDF is mostly vector text (not scanned), there is nothing to compress — the app honestly reports "File is already optimized" and won't degrade the document. The biggest gains come from scans and PDFs made from photos.
Where are results saved?
To the "Documents" tab inside the app. From there you can share via the system share sheet, open in another app (QuickLook), or delete.
How do I delete old files?
Swipe left on a row or long-press → Delete. Or enable auto-cleanup in Settings — the app will remove results older than N days automatically.
How do I change the interface language?
The app has its own language switcher independent of the system: gear icon top-right → Language → Русский / English / Español.
Does it work on iPad?
The current version supports iPhone only.
Requirements
iOS 17 or newer, iPhone.
Bug reports
If something went wrong, email us and include:
- iPhone model and iOS version (Settings → General → About)

We don't log anything to servers — all runtime info stays only on your device, so your report is what we need to understand the issue.
