Keep Plutocalc free

During the past 7 years Plutocalc was actively developed, improved and made available for free without displaying a single ad or tracking it's users. Plutocalc rapidly became the most popular water treatment app on the internet and nowadays, more than a hundred thousand experts rely on tool for their everyday professional needs.

Unfortunately, hosting, software licenses and equipment are not available for free. The developer has been funding this project from his personal income but as the user base increases, the costs go up and now the budget is under extreme pressure.

Plutocalc+ was released with the purpose of supporting development costs but less than 1% of the users cared to spend 3.99 USD for a lifetime license. It didn't worked out.

If you like this software and want it to continue free of ads free of money grabbing monthly subscriptions (yack!), please consider purchasing Plutocalc+ or making a small donation.
