How it works
Where collecting meets accountability
Find a cause you care about, take part, and walk away with something you can actually keep.
Discover
Browse campaigns from NGOs, brands, universities and communities — filtered to what you care about.
Take part
Donate, attend an event, make a purchase or complete a challenge. Four ways to qualify.
Collect
Scan the QR or scratch your physical sticker and enter the code. The klek is yours.
Unlock
Earn points as you collect, then redeem them for vouchers, discounts and partner perks.
The KLEKtion
Stickers worth keeping
Original artwork, made for each campaign. Some are open to everyone. Some are limited editions that stop at a fixed number, forever.
