Five panels, one each. What the company actually does, one piece of geometry taken all the way through, the register entry, the app itself, and where to write. No catalogue, no enquiry form, and no numbers that cannot be checked.

Pearlconvert AS publishes software for Android. The whole of it is designed, written, tested and maintained by one person, which is why there is no handover here between whoever reads an email and whoever goes and changes the thing the email was about.
The taste runs to puzzles: a rule you can state in a single line, and a difficulty curve that teaches without a tutorial. They are built to run without a network, which adds nothing to a puzzle, and without an account, since there is no reason a puzzle should find out anything at all about whoever is playing.
This page makes no claims about results, performance or growth, for anybody. It describes a company and an app, and every figure on it comes with the method that produced it.
Here is a fact about the tangram worth demonstrating rather than asserting. Pick up a piece below, then turn it or flip it over and watch what happens — or rather, watch what mostly does not.
Six of the seven pieces are mirror-symmetric, so turning one over lands it on a position you could have reached by rotating it. Press flip on a triangle and the shape that comes back is one of its own four turns. The parallelogram is the single exception. It has no line of symmetry, so its mirror image is genuinely a shape the other side cannot reach — which is the entire reason a tangram app needs a flip control at all. Across the set, rotation alone yields 23 distinct orientations; adding flips takes it to 25, and both of the two extra belong to the parallelogram.
The second number is quieter and stranger. Measured in small triangles, the pieces come to 4, 4, 2, 2, 2, 1 and 1 — exactly 16, the area of the square they were cut from. Every figure you can build uses all seven, so every figure has precisely the same area. A cat and a boat and a house differ in outline and in nothing else.
How it was checked: each piece was written out as a polygon in exact fractions, its area taken by the shoelace formula, and its four rotations and four mirrored rotations reduced to a canonical form and compared. Six pieces produced no new shape under mirroring; one did.
com.formbrikk.brikkerAn aksjeselskap is Norway's ordinary limited form: share capital paid in before trading begins, liability stopping at the company, annual accounts filed whether or not anything happened in the year. Nothing exotic, and nothing above that a reader has to take on trust — every line is a matter of public record.
A tangram on a felt play-table. Seven flat pieces — triangles, a square, the parallelogram from panel 02 — and a shadow to fill: a cat, a boat, a house, a bird. Drag, rotate and flip until the silhouette is covered exactly, with no gaps and no overlaps.
Every puzzle was built by actually laying the real pieces down, so a genuine solution always exists, and a hint can ghost one piece into position when a nudge is wanted. Figures are grouped into packs that climb from plain geometry to characterful shapes, and best times are kept. No network, no account, no advertising — and that combination is the reason the privacy policy runs as brief as it does.
Two addresses. post@pearlconvert.space takes anything to do with the company itself; brikke@pearlconvert.space takes anything to do with Brikker — a fault, a figure that refused to come together, a question about what the app stores. One person reads both, so the division is filing rather than routing.
Write in Norwegian or English, whichever suits. No acknowledgement is sent automatically, so a silence lasting more than a couple of working days almost certainly means the message never arrived; send it a second time.
