Five bands. The company, the register entry, the app, one calculation worked out in full, and an address. You will find no product list here, nothing to fill in, and no number that cannot be traced back to how it was obtained.
AUTO - RANKO d.o.o. publishes software for Android. The designing, the writing, the testing and the upkeep afterwards are all the work of one person, so there are no departments for anything to be handed between — the same person reads your message and then goes and fixes whatever it was about.
What gets made are logic puzzles: one sentence of rules, and a climb in difficulty gentle enough that no tutorial is needed. They run offline, since a network adds nothing to a puzzle, and they ask for no account, since a puzzle has no business finding out anything about whoever is playing.
No result, no performance figure and no growth claim appears anywhere here, on anyone's behalf. There is a company and there is an app, and each number comes with an account of how it was arrived at.
com.vidoset.pogledThe d.o.o. is the standard Croatian limited company: capital subscribed before business begins, liability confined to the company itself, and accounts lodged every year regardless of whether the year held anything. None of the lines above asks for your trust — all of them are on file in the court register.
A logic puzzle in the Kuromasu family, built entirely out of lines of sight. Every numbered cell states how many white cells it can see — itself, plus everything visible straight up, down, left and right until a black cell cuts the view off. Shade the right cells black so that every number comes out exactly, keeping to two rules: no two black cells may touch edge to edge, and the white cells must all remain joined in one piece.
Every grid is checked to have one unique solution, so nothing ever has to be guessed. It runs entirely offline, keeps no account and carries no advertising — which is the reason its privacy policy comes out as short as it does.
Here is a fact about sightline puzzles worth demonstrating rather than asserting. Move across the board below — any pale cell — and watch what the cell can actually see.
A genuine arrangement: 29 black cells, none touching edge to edge, and the 71 white cells all joined in one piece. The numbers are not given — this board is an illustration of the rule, not a puzzle to solve.
What this cell sees
—
Move onto a pale cell to cast a sightline from it.
Pointer, or focus the board and use the arrow keys.
A clue looks like it ought to describe an area, and it does not. It counts a cross — one arm in each direction, stopped wherever the first black cell stands — which is why the numbers on a hundred-cell board are so much smaller than the board. The largest a clue can ever be on a ten-by-ten is a full row plus a full column with the shared cell counted once: 10 + 10 − 1 = 19. The smallest is 1, a cell walled in on all four sides. So a board of a hundred cells admits exactly nineteen possible numbers, and on the particular arrangement above the counts run from 2 to 17, taking fourteen distinct values between them.
How it was checked: the arrangement was generated and then tested against both rules — no two black cells adjacent, every white cell reachable from every other — and the sightline of all 71 white cells was computed by walking outward in the four directions until a black cell or the edge stopped the walk. The page recomputes each count as you move, from the same board, by the same walk.
Two addresses. post@auto-ranko.store takes anything concerning the company itself; vid@auto-ranko.store takes anything concerning Pogled — a fault, a grid that looked wrong, a question about what the app stores. The same person opens both, so splitting them is a matter of tidiness and not of routing.
Croatian and English are equally welcome. Nothing here answers by itself, which means more than two working days of quiet is near-certain evidence that the mail went astray — try once more.
