Website terms
Terms of use.
Updated November 12, 2026. These terms describe perceptle.openguessr.org, provided by Perceptle.io.
Independent practice
You can play, choose settings and share your own generated challenges and results. This website is not affiliated with or endorsed by the original Perceptle's creators. Names belonging to other operators remain their property. Practice scores are for entertainment, not official dated-puzzle results, medical measurements, prizes or verified global rankings.
The scoring page explains calculations. Device, browser and audio latency can affect play. Keep mode, difficulty, skills and set count clear when comparing results.
Records and availability
Results and unfinished checkpoints are stored in your browser under this domain. IO and Daily records remain separate. There is no cloud recovery service. Use History export/import to keep completed-session backups. Imports keep at most the newest 100 completed sessions; keep a backup before merging. Unfinished checkpoints are separate.
Availability on every device and uninterrupted access are not guaranteed. Version changes may affect future challenge compatibility. Do not interfere with the service, attempt unauthorized access or present practice scores as certified results.
Advertising and questions
Google advertisements may appear in the completed-set results area. Playing, continuing, sharing and exporting do not require clicking or watching an advertisement. See Privacy for data use and consent choices.
For corrections, contact [email protected] or use Contact. Include enough information to reproduce the issue. These terms do not limit rights that cannot legally be excluded.
