ChainWhich is designed with privacy in mind.
Your streak statistics are stored only on this device. Your device also generates and stores a randomly generated ID that we use to track usage in our analytics.
No account required to play. We collect your email only if you subscribe to the daily reminder.
We collect usage data (examples: solve rates, attempt counts, device type) to improve puzzles. Analytics never include your name, email, or other personally identifiable information. Country-level location is derived from your timezone for geographic analytics.
We occasionally promote ChainWhich online. These platforms track data about who visits ChainWhich as a result of their ad. We share data back about those visitors in order to measure ad effectiveness. We honor Do Not Track browser settings.
When you create a community puzzle, we store the puzzle name, words, and decoys on our servers for 14 days, after which they are automatically deleted. Puzzles are linked to your anonymized session ID - we cannot identify who created a puzzle. Anyone with the share link can play your puzzle while it’s active.
Optional. If you sign up, we collect your email address and timezone so we can send one email a day when your puzzle resets. Reminders are sent through a third-party email service. Unsubscribe anytime. Sign-ups are for ages 16 and over.
By using ChainWhich, you agree to the following.
You are responsible for the content you create in community puzzles, including puzzle names, words, and decoys.
Do not create puzzles containing harassment, hate speech, explicit content, or material intended to harm others. Offensive language is automatically filtered.
We may review and remove any community puzzle at our sole discretion, without notice or explanation.
Community puzzles are temporary. They auto-delete after 14 days and may be removed sooner. We do not guarantee uninterrupted access to any puzzle.
ChainWhich is not responsible for content created by other users. If you encounter a puzzle you find objectionable, please contact us.
