Why it’s listed

'no ads, no profiling'1, open-source apps2, and a one-off price instead of a subscription.

The trade-off

German private equity firm Comitis Capital agreed to buy it in January 20263, so it's worth watching. ToS;DR grades it C4.

Price

USD 6.00 one-time for private use (shown 13 October 2026)5.
