SyncNos is a one-person project, built with care.
If you'd like to sponsor me, I have a small request: don't just send money — leave a message. Tell me why you use SyncNos, share a story, or simply say "keep going".
What keeps me going isn't the money — it's knowing someone cares. What connects us is emotion, not a transaction.
Special thanks to the linux.do community 💛
