Support Blocky ❤️
Blocky is free, open source, and developed in my spare time — with no telemetry, no data collection, and no hidden filtering. Thousands of people run Blocky; only a handful support it. If Blocky is useful to you, please consider chipping in — your support directly funds ongoing development and helps keep Blocky independent and ad-free, forever. Every contribution, however small, is hugely appreciated. Thank you! ❤️
