Privacy Policy
Last update: May 8, 2026
What we process
Opening Repair asks for a Lichess username and uses public Lichess games to build an opening repair report. We do not ask for your Lichess password and we do not access private games.
The app stores report jobs, reports, report items, engine evaluations, dismissed items, and reward-extension eligibility so the report can be shown again and extended without recomputing everything.
Browser storage
Your browser may store display preferences, sound preference, the last report link, selected tabs, review choices, and temporary training progress. Some training state is kept in session storage and can disappear when the browser session ends.
Service data
Our hosting provider and server may process technical data such as IP address, browser information, requested pages, timestamps, and errors. We use this to deliver the website, diagnose problems, and keep the service secure.
We do not use advertising trackers or analytics tools at this time. External services linked from the app, including Lichess, process data under their own terms.
Your rights
You may have rights under applicable privacy law, including the right to access, correct, or erase your personal data, and to object to certain processing. You may also lodge a complaint with the Dutch Data Protection Authority (Autoriteit Persoonsgegevens).
