How we build
Useful over loud.
Each product is built around a clear job, a narrow data footprint, and controls that say what they actually do.
Local first
Sensitive state stays on the device whenever the product can work that way.
Plain language
Fees, actions, permissions, and tradeoffs should be reviewable before commitment.
No ad machine
Our website has no analytics or tracking pixels. Our products do not fund themselves with ads.
