Privacy Policy

Updated:

This policy explains what 易迅记账 processes, why, how long it is kept, and how to exercise your rights.

Scope and contact

This policy applies to the mainland China edition of 易迅记账 V1 for personal and family bookkeeping, operated by Shanghai Yu An Shan Shi Technology Co., Ltd. under the public brand VCEAU · 屿岸山石.

To access, correct, copy, export, or delete data, withdraw consent, or report a privacy concern, email support@vceau.co. We verify account ownership before acting on account data.

First launch and consent

Cloud account, sync, and other online initialization start only after you choose “Agree & Continue” and the device saves and verifies that choice. If you decline, the app does not start cloud initialization or automatic network requests.

Privacy/Terms consent is separate from third-party AI consent. Material policy changes receive a new version and, when required, a new consent request.

Data we process

Purposes and permissions

Family sharing, providers, and transfers

A family owner manages members and shared ledgers. Authorized members can view or add shared entries. Do not enter another person’s information unless you are allowed to share it.

We may use Alibaba Cloud compute, database, object storage, SMS, or email services. Current mainland China AI processors are Alibaba Cloud DashScope and ByteDance Volcano Engine. Apple, Google, or WeChat independently processes the information needed for the selected sign-in method; WeChat sign-in uses the WeChat Open SDK and Open Platform services.

易迅记账 does not intentionally route mainland China ledgers or AI requests to international model services. Before any future cross-border transfer that requires notice or separate consent, we will identify the recipient, purpose, data categories, and rights channel and obtain consent as required.

Retention and security

Your rights and children

You may view and correct ledgers, copy or export data, withdraw Privacy/Terms or AI consent separately, and request access, correction, or deletion. Withdrawing Privacy/Terms consent pauses account and cloud features until you consent again.

Delete in “Settings Center → Account → Delete Account & Data,” or use the deletion page/email if you cannot sign in.

易迅记账 does not offer standalone accounts to children under 14. A guardian may contact us to remove information submitted improperly.

One-time trial eligibility and abuse prevention

To provide and enforce one seven-day trial per verified identity, 易迅记账 uses a keyed HMAC on the server to derive pseudonymous fingerprints from verified phone, email, or third-party sign-in identifiers. The trial-eligibility record contains neither the raw identifier nor the deleted user ID.

After account deletion, the trial-eligibility fingerprint remains for the lifetime of the one-time trial program solely to determine eligibility, prevent repeated-registration abuse, and protect the service. It is not used for advertising or cross-service tracking. Retired key versions may be retained during key rotation to recognize an existing claim.
