Frequently Asked Questions
Instant answers to common questions regarding security, performance, and usage.
If I lose the password, can you help?
No. Encryption happens locally on your device; we never see your password or your file.
Is it compatible with Mac/PC?
Yes. Protected files follow the official PDF standard and work in all major viewers.
Is it really secure?
Yes. We use standard crypto libraries that make the file unreadable without the correct key.
