CSES Forge does not collect, store, or transmit any personal data to its developer. It does not use analytics, tracking, or advertising of any kind.

Data handling:
- Your code and editor settings are stored locally in your browser (via the WebExtension storage API), scoped to your CSES account and the problem you're solving. This data never leaves your device except as described below, and is never sent to the developer.
- When you click "Run," your code and test case input are sent to Wandbox (wandbox.org), a free public code execution API, solely to compile/run it and return the output to you. No data is retained by CSES Forge after displaying the result.
- When you click "Submit," CSES Forge fills in and submits CSES's own official submission form on cses.fi, using your existing logged-in CSES session — exactly as if you had submitted it yourself. CSES Forge does not intercept, log, or store your submission.

CSES Forge only communicates with cses.fi and wandbox.org, and only as a direct result of your own actions (viewing a problem, running code, submitting a solution).
