Your data at Think Operator

Progress stays in your browser

The app stores completed scores, answer accuracy, test dates, skill results, and daily decisions in local browser storage. It does not currently send these results to an account or a database. Anyone using the same browser profile can see them. They do not automatically transfer between browsers, devices, domains, or HTTP and HTTPS.

Up to 100 recent runs are retained for each test type and each skill, alongside personal bests and up to ten years of daily decisions. Older entries outside these limits are removed. Clearing site data or using private browsing may remove your progress.

We also remember up to 1,000 recently shown Quick Decisions scenario IDs to reduce repeats across rounds. This rotation history is included in backups and removed when you reset progress.

Back up or delete your progress

Use My progress to download a JSON backup, restore a backup, or delete your saved progress. A backup contains your test history, so share it only if you want someone to see those results.

Hosting and tracking

This preview is hosted by GitHub Pages. Like any web host, GitHub receives connection information such as your IP address when serving the site. See GitHub’s privacy statement for its handling of that information. We have not added advertising trackers, analytics scripts, account registration, or payment collection.

What scores mean

Scores are practice feedback from the current question bank, not a professional certification or a validated hiring assessment. They are calculated on your device and can be edited by its user. Daily community percentages are illustrative examples, not measurements of real users.

Future accounts

Accounts, cloud sync, and payments are not active. Before those features launch, this page will be updated to describe the data collected, service providers, retention, and account deletion process.
