Privacy Policy

Last updated: 2026-09-06

FlowScore (operated by FlowCoder) has no user accounts and does not collect personal information such as names or email addresses.

Test records are stored only in your browser localStorage. Apart from records you submit to the Hall of Fame (see below), we keep no database of personal records. Backup files and backup codes are downloaded and kept by you; they are never sent to us. Note that share links carry your result values in the URL (?s=), so the URL may appear in the access logs of the browser and hosting server that open it. Do not create a link for a record you do not want to share.

We may use Google Analytics for visit statistics. We may use Google AdSense to serve ads. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. You can opt out of Google's use of advertising cookies (such as the DoubleClick cookie) at https://adssettings.google.com, and of other vendors' cookies at www.aboutads.info.

Links on the gear page may be affiliate links. We may earn a commission on purchases at no extra cost to you.

If you submit a record to the Hall of Fame, your nickname, the record value, your country (derived from the connecting IP) and the submission time are stored on our server (Cloudflare Workers and D1, hosted outside Korea) and shown publicly on the ranking table. Records that made a board are kept until you ask us to remove them. To count the daily submission limit we keep a non-reversible hash of the IP address for up to 2 days; the raw IP is never stored. If a record falls outside the review range and is held for review, we also keep the device type (touch or not) and how many times this browser took that test, and delete both once the review is done. Records pending review or rejected are deleted within 30 days. To stop the same record being submitted twice we keep only its attempt id and the original response, which contain no nickname or IP. To have a submitted record removed, contact us at the address below.
