Privacy Policy

Mizukagami handles information only to the extent needed to improve the simulation experience and operate the service. The items below explain what is stored, why it is used, and how it is handled.

1. Information we store

We store the asset, input mode, input value, purchase date, staking setting, selected event, and calculation timestamp used for each simulation.
For ranking identity management, we handle a browser_id and an IP hash. Raw IP addresses are not stored.

2. Purposes of use

We use the data to understand which assets and dates are frequently simulated and to improve the UI and aggregation features.
We also use it to reduce duplicate ranking submissions and control rapid repeated posting.

3. Handling policy

Stored information is used only for operating and improving Mizukagami.
It is not used for advertising purposes or to identify an individual user.
It is not provided to third parties except when required by law.

4. Site assumptions

Mizukagami is a hindsight simulation site focused on buying on a past JST date and holding until now.
It does not provide forward-looking investment advice or a calculation mode based on what if you had never sold.

5. Rights for images and logos

Rights to the logos, icons, and related images of each crypto asset shown on this site belong to their respective rights holders.
Those images are used only as needed for asset identification and share card presentation.
If a rights holder requests revision, removal, or a change in presentation, we will review the request and respond appropriately.

6. Revisions

If the scope of stored data or the purposes of use change, this page will be updated accordingly.
