Look at your pirate audience from a different perspective

We researched 500+ pirated apps and games, and asked 70+ developers and 300+ pirate users:

72%

pirate
users

would buy a license if a pirated copy
‍wasn’t available.

53%

pirate
users

would buy a license if it was on sale
or cheaper.

46%

revenue
growth

on average when an app gets protected
and un-pirated.

Most app developers give up on piracy and don’t use any protection mechanism.

Most app developers don’t know what to do and how to work with their pirate audience.

Most pirate users are loyal to their apps and not interested in free or alternative products.

Un-pirate your app and convert these “lost users” into loyal customers

Pirate audience is your most valuable and overlooked asset. You’ve alread sold it to them – they just haven’t paid yet.

Love your app

Pirate users are the best sales leads: they know your product, they already use it, and they’ve chosen it over every other app.

Able to pay

They managed to pay for Mac and iPhone – they’ll manage to pay for a license when your app is no longer available for free.

Highly convertible

The question is not if they will buy, the question is how many of them will buy, and how to optimize and maximize this conversion!

Do the math yourself

If you want to see real examples, just ping us for the numbers.

Advanced code protection with logic obfuscation

Secretly uses advanced logic obfuscation to safeguard mission-  and revenue-critical code against reverse engineering.

Time-proven approach and technology that works

Secretly is not another dynamic library or plug-n-play solution – they never worked and never will.

Framework-agnostic

Secretly doesn’t care what licensing mechanism you’re using, be it Paddle, Mac App Store, Setapp, Fastspring, or anything else.

Zero-dependency

Secretly doesn’t rely on frameworks, libraries, build tools, or other other dependencies that always break. It’s only your code and nothing else.

Continuously-reinforced

Secretly allows to obfuscate every release for hardening each build and preventing reoccurring patterns in your ASM code.
