Using the tools
Why doesn't a file open?
Check that the format is compatible, that the file is not damaged or protected, and that it does not exceed the limit indicated on the screen.
Does Luna4 replace my original file?
No. The result is downloaded as a new file. Always keep the original when it is important.
Does it work on mobile phones?
Yes, although very large files may exceed the available memory. For video, audio or large batches it is better to use a desktop computer.
Privacy
Does Luna4 see my files?
Current tools process content in your browser. The membership API receives the type of tool used, never the file, its name or its content.
What data does an account save?
Name, email and photo of Google, membership status, secure sessions and advanced operations of the day. Payments are managed through PayPal.
Limits and membership
What does five uses a day mean?
An advanced operation consumes one use when you press the process button. The counter is reset every day according to Dominican Republic time.
Do I need an account for the free plan?
No. You only need to log in with Google to activate or manage a Pro membership on different devices.
How do I request help with a collection?
Use the contact form and select “Membership and payments”. Do not send complete information about your card.
