❓ Frequently Asked Questions
How do I cancel my Pro subscription?
Go to iOS Settings → [Your Name] → Subscriptions → PDF Lock: Unlock & Protect and tap Cancel Subscription. Your Pro access continues until the end of the billing period.
I purchased Pro but the app shows Free. What do I do?
Open the side menu in the app and tap Restore Purchases. Make sure you're signed in to the same Apple ID used for the purchase.
Are my PDF files uploaded anywhere?
No. All PDF processing happens entirely on your device. Your files are never uploaded to any server. See our Privacy Policy for full details.
Why does the app ask to open a PDF file from another app?
PDF Lock: Unlock & Protect supports "Open In" from Files, Mail, Safari, and other apps. This is a standard iOS feature that lets you process PDFs without leaving the app. No data leaves your device.
I forgot the password I set on my PDF. Can you help?
We do not store any passwords you set. For security reasons, PDF passwords cannot be recovered without the original password. Please keep a record of passwords you set.
Can I get a refund?
Refunds for in-app purchases are handled by Apple. Please visit reportaproblem.apple.com to request a refund from Apple directly.
