Frequently asked questions

What is KEIKEN and how do I use it?

KEIKEN is a location game: explore the map, discover spots, collect them with GPS check-in, and fill your passport with stamps and progress.

What does “collect” mean?

Collecting is a GPS check-in within your subcategory’s radius (100 m by default). The server rejects check-ins if you are too far away. Your Hanko stamp is proof of the collect.

How do I collect and create spots?

Open a spot on the map and collect when you are on site. You can suggest new spots for the community — you cannot collect a spot you created yourself.

How do badges and medals work?

See the badge catalog on your profile. Bronze, silver, and gold medals unlock at 5, 15, and 50 collects in the same subcategory. Chapters advance with your level; curated places and recommendations have their own badges.

What is “My campaign”?

Story fragments unlock as you level up: chapter 0 at the start, then every 5 levels up to level 50.

How do I delete my account?

In the app: Settings → delete account. You can also use keiken.life/delete-account. Your profile becomes invisible immediately; data is permanently deleted after 15 days. Sign in again before the deadline to restore.

How do I report content or block someone?

Use Report from a profile, spot, or comment menu (harassment, spam, wrong location, etc.). Blocking is available in Settings.
