§06 / Straight answers

FAQ

The questions people ask most before trying it, answered straight.

  • Where is my data stored?

    After you sign in, your records are stored under your own account and used to sync across devices. GANKAN has no analytics, ads, or crash reporting, and your records are never used for anything else.

  • Does it cost anything?

    Completely free during the beta. If it ever costs money, it will only be for extras like multiple savings goals, and data you have already logged will never be locked.

  • Why convert to time?

    Money is abstract. Time is not. ¥88 does not look like much, but at ¥66 an hour it is 1 hour 20 minutes of your day. In time, it is easier to ask yourself, “is it worth it?”

  • Will it judge my spending?

    No. The five reasons share the same size and color, there is no red flag on “impulse”, and there is no savings score. It just puts the numbers on the table, and how you read them is up to you.

  • What device do I need?

    iPhone only for now, installed through TestFlight. There is one test link for mainland China and one for friends abroad. I will send you the right one by email.

  • What can I give feedback on?

    Anything: what is unclear, what feels off, what is missing. Email me and I will reply myself. Try it for a week or two and tell me what is wrong.
