Câu hỏi thường gặp

Is it legal to remove a PDF password?
You may only unlock PDFs you own or have explicit permission to modify. SeerKits does not bypass encryption without the correct password and prohibits misuse.
What if I do not know the password?
SeerKits cannot recover forgotten passwords or crack protected files. Contact the document owner or use your original unencrypted copy.
Are my files stored after unlocking?
No — files are processed securely and deleted immediately after download. We never retain document contents on our servers.
