Privacy Policy

Last updated: August 5, 2026.

Calculator inputs

In the current version, calculator inputs are generally processed in your browser and are not intentionally sent to a EgoTools database. Some tools may contact third-party public APIs, such as Wikimedia, to retrieve historical information.

Health estimates

Tools such as Heartbeats Alive provide user-controlled entertainment estimates and are not medical measurements or health advice.

Local exploration progress

EgoTools may use browser local storage to remember which tools have been explored on that device. This is used only for the local exploration counter and does not require an account.

Game best scores

Some mini-games use browser local storage to remember a best score on that device. EgoTools does not require an account for these scores.

Analytics

EgoTools includes optional analytics support, but it is disabled until a valid analytics identifier is configured. Where optional analytics cookies are used, visitors can reject them through the consent notice.

Advertising

If advertising is added in the future, this policy will be updated to explain the advertising providers, cookies and controls in use before personalised advertising is enabled.

Third-party services

Wikimedia-powered features may send the requested month/day and ordinary technical request information to Wikimedia's servers. Their services are governed by their own policies.

Contact

Use the contact page for privacy questions or requests.

Favorites, streaks and local records

EgoTools may use browser local storage to remember favorites, game personal bests, optional sound preference, tools explored, and Daily Challenge streak information on that device. These features do not require an EgoTools account.

Challenge links

If you create a “Beat my score” link, the score to beat is placed in the URL you choose to share. Do not include personal information in shared URLs.

Server-recorded challenges

When you create a competitive EgoTools challenge, the server stores the game, score, challenge code, language, creation time, expiry time and optional parent challenge so the shared link can display the same recorded result to everyone who opens it.

For abuse prevention and rate limiting, EgoTools stores salted one-way hashes derived from the requesting IP address and browser user-agent. The challenge database does not store the raw IP address in these fields. Hosting/server logs may still be processed separately by the hosting provider as part of normal website operation.

Challenge records expire after approximately 180 days. Short-lived game-session tokens expire after approximately two hours. Expired records are periodically removed.
