Account & Data Deletion

This page explains how users of Zellia, operated by Hainan Huace Zhikang Huanbao Gongcheng Co., Ltd., can delete their account and request deletion of associated personal data. It is intended to satisfy app store account deletion disclosure requirements and to provide a deletion path even when you cannot access the app.

Data deleted when your account is deleted

When your account deletion is processed, Zellia deletes or anonymizes account-linked personal data from active systems, including:

• Account profile, email, username, nickname, avatar URL, activation code data, and authentication records controlled by Zellia;
• Medication plans, reminder settings, medication logs, missed-dose prompt records, and related care data;
• Blood pressure, heart rate, blood glucose, and other wellness entries linked to your account;
• Family links, family aliases, invite/QR relationship records, family action logs, PRO sharing records, and caregiver/elder relationship data involving your account;
• Device push tokens and notification device labels;
• Subscription event records stored in Zellia's backend that are linked to your account;
• Family voice reminder URLs and voice objects stored on Cloudflare R2, on a best-effort basis;
• Cached clinical snapshot data and app preferences linked to your account where technically feasible.

Deleting one account may also remove family links involving that account. Other users may lose access to shared family views connected to the deleted account.

Option 1 - Delete in the app (recommended)

Option 2 - Request deletion by email

If you cannot access the app, send an email from the address associated with your Zellia account to:

support@dothings.one

Use this subject line and template:

We may ask you to verify ownership of the account or email address before processing the request. Do not include detailed medical information in the deletion request email.

Delete specific data without deleting account

You can submit a request to delete certain data that Zellia collected through this app without deleting your entire account. This may include activity history, care records, transaction-related records under Zellia's control, profile images, family voice reminders, and other images, audio, or video files linked to your account.

To request deletion of specific data, email support@dothings.one from the email address associated with your Zellia account and describe the data you want deleted. You may also include the app data deletion page link in your request: https://zellia.dothings.one/data_deletion.

We may ask you to verify ownership of the account and clarify the scope of the request before deleting specific data. Deleting specific records may affect related app features, history views, reports, reminders, family sharing, or subscription support.

Active subscriptions

Account deletion does not automatically cancel a Google Play or other app store subscription. To avoid future charges, cancel Zellia PRO in the store account used for purchase. On Android, open Google Play Store - Profile - Payments & subscriptions - Subscriptions. See our Subscription Terms for details.

Processing timeline

• In-app deletion: starts immediately after confirmation. Most active records are removed promptly; backup copies may persist for up to 30 days before scheduled deletion.
• Email requests: we aim to confirm receipt within 7 business days after receiving enough information to identify the account and complete deletion within 30 days after verification.
• R2 voice files: deletion is performed on a best-effort basis after account database records are removed. If storage deletion temporarily fails, we retry or investigate when notified.

Data we may retain

We may retain limited information when necessary to:

• Comply with legal, accounting, tax, platform, or fraud-prevention obligations;
• Resolve disputes, enforce agreements, investigate abuse, or protect security;
• Maintain backup, audit, and security logs for a limited retention period;
• Keep app store or RevenueCat records that are controlled by those providers or required to verify transactions, refunds, chargebacks, or entitlement history;
• Maintain aggregated or de-identified information that cannot reasonably identify you.

Retained data is restricted and is not used for marketing.

Data controlled by other providers

Some data may be controlled by third parties, such as Google Play purchase records, Firebase authentication records, OAuth provider account data, device-level notification settings, or app store receipts. We will delete data under Zellia's control, but you may need to manage third-party account or purchase records through those providers.
