Account Deletion
This page explains how to request deletion of your account and related data in the Ahns Metronome app. It is provided in accordance with Google Play's Account Deletion Disclosure policy.
1App and Contact Information
2How to Request Account Deletion
Method A — Delete directly in the app (recommended · immediate)
- Open the app → go to the Settings screen
- Select the "Delete account" link at the bottom
- To prevent mistakes, type "Delete" in the confirmation field
- Your account is deleted immediately upon entry, and logins (authentication tokens) on all devices are revoked together
Because signing in with your Apple ID / Google account is itself your identity verification, deletion is processed immediately without any separate email verification code or password confirmation. This is the fastest and safest method.
Method B — Request via email
If you cannot access the app and direct deletion is difficult, please request it through the following steps.
- Send an email to: ahnsapp@gmail.com
- Subject:
[Account Deletion Request] Ahns Metronome
- Include the following in the body:
- Your login method (Apple or Google) and account email
- Your in-app nickname (for verification)
- Reason for deletion (optional)
- After identity verification, it is processed within up to 5 business days
3Data That Is Deleted
Upon account deletion, the following data is deleted and cannot be restored.
| Category | Items |
|---|
| Account info | Social identifier (Apple/Google provider UID), email (if collected), nickname, birth year |
| Authentication info | Login token (JWT refresh token) — revoked immediately on all devices |
| Settings | User preferences such as BPM, time signature, sound, and theme |
| Premium status | Premium expiration date, ad-watch count, accumulated days |
| Community & friends | Posts/comments you wrote, friend relationships/groups, report/block records |
| Access records | Access IP and device info at sign-up/modification |
Upon deletion, your member information is destroyed immediately. You may sign up again later with the same Apple / Google account.
4Data That Is Retained (Legal Obligation)
Some data is automatically destroyed after a certain period in accordance with legal obligations. (Only minimal information such as transaction identifiers applies.)
| Item | Retention period | Basis |
|---|
| Payment / consumer-dispute records (transaction identifier) | 5 years | Act on Consumer Protection in Electronic Commerce |
| Access logs (last access time, device info) | Deleted on account closure | Not retained |
We do not retain permanent identifying information for re-signup blocking.
The past email-signup-era policy of "permanently retaining an SHA-256 hash of the email" has been abolished. The Service is now based on Apple / Google social login, and you may freely sign up again with the same account after deletion.
However, to prevent sign-up free benefits from being granted twice, a one-way hash of your social account identifier (SHA-256, cannot be reversed to the original) is retained; this does not restrict re-signup itself.
5Result of Processing
- In-app deletion takes effect immediately upon typing "Delete" — there is no separate notification.
- For deletion requested via email, we notify you by reply when processing is complete.
- Data is not restored after deletion.
- Payment refunds on the App Store / Google Play are separate from this procedure; please proceed according to each store's refund policy.
