One person.
No shortcuts.
Considus is an independent software studio. There is one person here. No team, no investors, no product roadmap driven by growth targets.
Every product is built because it ought to exist, because there is a real gap, a real person without a good answer, and because making it well is worth the time it takes.
The studio was founded in 2026 following the UK government's removal of Advanced Data Protection from iCloud, the feature that provided genuine end-to-end encryption for Apple Notes and Reminders. That decision made visible a gap the market had not filled, software that feels as considered as Apple's own tools, built with privacy as a structural truth rather than a marketing position.
Catchlight is the first answer to that gap. More things will follow when they are ready.
The name
Con Sidus, from the Latin, is to stargaze, to navigate by fixed points of light. Considera is to think carefully before acting. And said aloud it carries an invitation, consider us.
Pronounced con-SEE-dus. Three syllables.
Five constraints
These are not marketing claims. They are the standards every product built under the Considus name must meet.
Permanence over novelty
A Considus product is built to last. No VC timeline, no pivot, no sunsetting because growth stalled. If it earns its place, it stays.
Privacy as infrastructure
Not a feature. Not a badge. Not an upgrade tier. The correct way to build anything that holds private data. End-to-end encryption is the baseline.
Simplicity as the hard problem
Every Considus product is harder to simplify than to complicate. Complexity is the easy path. Restraint is the discipline.
An honest business model
No dark patterns. No data as payment. One honest price for a complete product, or free and open where that serves better.
Craftsmanship over completeness
A small number of things done with real quality is worth more than a large number done adequately.
