Your practice. Your information.

What stays on your device

We use browser local storage for guided-puzzle and lesson completion, placement answers and estimates, practice history, imported PGNs, game notes, assignments, endgame attempts, and your light or dark theme preference. Importing a game or restoring a backup reads that file in your browser. If you connect this workspace to an account, its saved games and notes are included in subsequent cloud saves.

These records remain until you replace or remove them, or your browser clears its storage. Different devices, browser profiles, and website addresses have separate storage. Private browsing may remove records when you close the session.

Optional learning reports

In Progress, you can preview and download a small piece-safety report. It includes exercise outcomes, the report date and any multiple-choice feedback you select. It excludes email addresses, game files, private notes and reflections. Feedback answers remain in the form until download and are cleared when you leave the page; they are not added to cloud progress.

Creating a report does not send it to our team. You choose whether to share the downloaded file, and with whom. This report is separate from a complete workspace backup, which includes games and notes.

Optional accounts and cloud progress

Supabase processes your email address, sign-in sessions, and the workspace you choose to save. This includes placement answers and estimates, training and lesson history, imported games and their player names, notes, assignments, and endgame attempts. Your account identifier links that copy to you. Your theme preference remains on your device.

Resend delivers one-time sign-in codes to your email address. These messages are for account access, not a newsletter. Supabase, Resend, and your email provider also process technical delivery and security information. See Supabase’s privacy policy and Resend’s privacy policy.

After you connect a workspace, saves run while the app is open and connected. Conflicting device copies require you to choose which to continue. Signing out keeps a recovery copy on this device and restores the earlier guest workspace. Clear browser site data to remove local copies. Signing out does not delete the account.

Use Account → Delete my account to remove your account and its current cloud workspace. Deletion also clears this account’s active workspace and recovery copy in that browser when browser storage is available. Guest backups, other devices, and downloaded files must be cleared separately. Provider backups and operational logs may remain under their retention policies; deletion is not a promise of immediate removal from every provider backup.

What leaves your device

• Website requests. Our hosting infrastructure receives requests to serve the website, chess-engine files, and other assets. Cloudflare processes technical connection information, which may include IP addresses, request URLs, and browser information, to deliver and protect the service. Operational logs may be used to investigate failures. See Cloudflare’s privacy policy.
• Endgame checks. Opening and playing a practical endgame sends its board position in FEN notation to tablebase.lichess.ovh. The service also receives normal connection information such as your IP address. The request does not include your notes, full game file, or placement history. See Lichess’s privacy policy.
• Support messages. If you choose to contact us, your email provider and ours process the message and any information you include so we can respond. Avoid sending passwords or an entire personal backup unless it is needed and you choose to share it.

During private previews, the platform hosting that preview may also require sign-in and process access information under its own privacy policy. That access account is separate from your locally saved chess progress.

Analytics, ads, and Google Search

The application does not currently include advertising, session replay, or an analytics tracking script. Google Search Console helps us understand how public pages appear in search; verifying the domain does not install a Google Analytics script in the app. Hosting infrastructure can still process operational traffic data.

Your choices

• Download a complete backup from Progress to keep or move your work.
• Clear the website’s site data in your browser to remove local records. Delete downloaded backups separately.
• Use lessons, guided puzzles, and local game analysis without opening the external endgame checker.
• Choose what you include in an imported PGN or support message. PGNs can contain player names and other personal details.

We cannot recover deleted local progress without a backup, or read and delete records stored only in your browser on your behalf.
