PSNDL is 100% free to use and 100% free of ads.
If you paid something to use it, get a refund as fast as possible.
Keep in mind that I [Jamesst20] spent a lot of time building this website and I never earnt a penny by doing so, it's quite the opposite. Web hosting and domain renewal is not free. I have monthly bills to keep PSNDL running.
The best way to thank me and show your interest is to get me a cup of coffee.
Please, never donate against your will.
PSNDL is 100% open source. Donating is not the only way you can contribute to the project.
Feel free to fork me on BitBucket, add new features or bug fixes and send me a pull request anytime to merge your changes.
