Account & Data Deletion Request
App: SevenBill (七只记账) · Android package acchw.top.acc_app
Once your account is deleted you will no longer be able to sign in, and all data in the
account is permanently deleted after 30 days and cannot be recovered.
Please export your bill data in the app before submitting a deletion request.
You can delete your account and personal data in either of the following ways:
Option 1: Delete in the app (recommended, takes effect immediately)
- Open the SevenBill app and sign in to the account you want to delete;
- Go to Settings → Other settings → Delete account;
- Read the notice, tick the confirmation box, and enter the verification code to verify your identity;
- Tap Delete account permanently and confirm in the dialog. The account is disabled immediately.
Option 2: Request by email (if you have uninstalled the app or cannot sign in)
- Send an email from the address you registered the account with to
matrixelem@gmail.com.
Requests sent from any other address cannot pass identity verification and will be rejected, so that your account stays protected.
- Use Account Deletion Request as the email subject;
- Include the following account identifiers in the message body so that we can verify your identity:
- Registered email address (required)
- Username (required; shown on the “Me / Settings” page in the app)
- Approximate registration date, or the date of your last recorded bill (optional, helps verification)
- Once verified, we delete the account and reply by email to confirm the result.
✉ Open your email app to send the request
If the button does not open your email client, please email matrixelem@gmail.com manually.
Data that will be deleted
After identity verification the account is disabled immediately (sign-in blocked, scheduled bills stopped). The following data is permanently and irreversibly deleted by the system after the 30-day cooling-off period:
- Account profile: username, password, bound email address, phone number, avatar;
- Bookkeeping data: bill records, ledgers, custom income/expense categories, asset accounts and asset flows;
- Feature data: scheduled bills, item deadlines, in-app notifications, personalized settings;
- AI data: AI chat history and AI-generated voice files;
- Sharing relations: shared ledgers you created are dismissed and other members lose access; your membership in other people's ledgers and any ledger invitation codes are deleted as well.
Data retained as required by law
The following data is not deleted together with the account, because financial reconciliation and compliance audits legally require it. It is kept to the minimum necessary extent and is never used for personalization or marketing:
| Retained data | Reason | Retention period |
|---|
| Order and payment records from membership purchases (order number, amount, payment time, payment status) |
Financial reconciliation, refunds and payment disputes, tax and compliance audits |
Kept for the period required by applicable financial and tax regulations, then destroyed |
| Deletion archive record (original account ID, registered email, deletion time and source) |
Proving that the deletion took place, handling post-deletion appeals, security audits |
Kept for the period required by applicable laws and regulations, then destroyed |
Processing time
- In-app deletion: effective immediately upon submission;
- Email request: we complete identity verification and deletion within 7 business days of receiving your email (no more than 15 business days in exceptional cases), and reply by email to confirm;
- Data purge: after the deletion is executed, the data listed above is permanently removed by the system at the end of the 30-day cooling-off period.
Please note
- Deletion is irreversible, and any remaining membership time is not refundable;
- The same email address can be used to register a new account, but the original data will not be restored;
- For any question about this page or about how your personal data is handled, email matrixelem@gmail.com.
