Spark & Anvil Privacy

For grown-ups

OrthoForge asks how the world writes down sound. Seven writing systems make six different design choices: an alphabet (English, Ukrainian, Vietnamese), an abjad (Arabic), an abugida (Hindi), a syllabary (Japanese kana), a featural alphabet (Korean) and logography (Chinese). With the right key, a reader can decode four of them.

Each round mixes decoding with a few “why does it work this way?” questions. A wrong answer shows which misreading was made, such as reading Cyrillic by its English look-alikes or keeping a Hindi vowel the language drops. Three reading cases (a sign, a name, a root) sit under Cases, and every system and its key is on the Systems page.

Nothing is timed.

What it never does

  • No ads and nothing to buy (see the privacy page).
  • No account needed: what is practised stays in this browser, on this device.
  • No streaks, timers to beat, points to chase or leaderboards.
  • No chat, and nothing anyone types is sent anywhere.

We describe what OrthoForge is designed to practise (ages 15–18). We do not claim it raises test scores.
